The emergence of generative AI has ushered in a new era of possibilities, enabling the creation of human-like text, images, code, and more. However, as exciting as these advancements are, data scientists often face challenges when it comes to developing UIs and to prototyping and interacting with their business users. Traditionally, building frontend and backend applications has required knowledge of web development frameworks and infrastructure management, which can be daunting for those with expertise primarily in data science and machine learning.

AWS provides a powerful set of tools and services that simplify the process of building and deploying generative AI applications, even for those with limited experience in frontend and backend development. In this post, we explore a practical solution that uses Streamlit, a Python library for building interactive data applications, and AWS services like Amazon Elastic Container Service (Amazon ECS), Amazon Cognito, and the AWS Cloud Development Kit (AWS CDK) to create a user-friendly generative AI application with authentication and deployment.

Solution overview

For this solution, you deploy a demo application that provides a clean and intuitive UI for interacting with a generative AI model, as illustrated in the following screenshot.

The UI consists of a text input area where users can enter their queries, and an output area to display the generated results.

The default interface is simple and straightforward, but you can extend and customize it to fit your specific needs. With Streamlit’s flexibility, you can add additional features, adjust the styling, and integrate other functionalities as required by your use case.

The solution we explore consists of two main components: a Python application for the UI and an AWS deployment architecture for hosting and serving the application securely.

The Python application uses the Streamlit library to provide a user-friendly interface for interacting with a generative AI model. Streamlit allows data scientists to create interactive web applications using Python, using their existing skills and knowledge. With Streamlit, you can quickly build and iterate on your application without the need for extensive frontend development experience.

The AWS deployment architecture makes sure the Python application is hosted and accessible from the internet to authenticated users. The solution uses the following key components:

• Amazon ECS and AWS Fargate provide a serverless container orchestration platform for running the Python application
• Amazon Cognito handles user authentication, making sure only authorized users can access the generative AI application
• Application Load Balancer (ALB) and Amazon CloudFront are responsible for load balancing and content delivery, so the application is available for users worldwide
• The AWS CDK allows you to define and provision AWS infrastructure resources using familiar programming languages like Python
• Amazon Bedrock is a fully managed service that offers a choice of high-performing generative AI models through an API

The following diagram illustrates this architecture.

Prerequisites

As a prerequisite, you need to enable model access in Amazon Bedrock and have access to a Linux or macOS development environment. You could also use a Windows development environment, in which case you need to update the instructions in this post.

Access to Amazon Bedrock foundation models is not granted by default. Complete the following steps to enable access to Anthropic’s Claude on Amazon Bedrock, which we use as part of this post:

1. Sign in to the AWS Management Console.
2. Choose the us-east-1 AWS Region from the top right corner.
3. On the Amazon Bedrock console, choose Model access in the navigation pane.
4. Choose Manage model access.
5. Select the model you want access to (for this post, Anthropic’s Claude). You can also select other models for future use.
6. Choose Next and then Submit to confirm your selection.

For more information on how to manage model access, see Access Amazon Bedrock foundation models.

Set up your development environment

To get started with deploying the Streamlit application, you need access to a development environment with the following software installed:

• Python version 3.8 or later. You can download Python from the official website or use your Linux distribution’s package manager.
• The AWS Command Line Interface (AWS CLI). For installation instructions, see Installing or updating to the latest version of the AWS CLI.
• The AWS CDK. For installation instructions, see Getting started with the AWS CDK.
• Docker or Colima. For installation instructions, see Install Docker Engine. For macOS, we have tested the deployment with Colima container runtimes in replacement for Docker Desktop.

You also need to configure the AWS CLI. One way to do it is to get your access key through the console, and use the aws configure command in your terminal to set up your credentials.

Clone the GitHub repository

Use the terminal of your development environment to enter the commands in the following steps:

1. Clone the deploy-streamlit-app repository from the AWS Samples GitHub repository:

git clone https://github.com/aws-samples/deploy-streamlit-app.git

2. Navigate to the cloned repository:

cd deploy-streamlit-app

Create the Python virtual environment and install the AWS CDK

Complete the following steps to set up the virtual environment and the AWS CDK:

1. Create a new Python virtual environment (your Python version should be 3.8 or greater):

python3 -m venv .venv

2. Activate the virtual environment:

source .venv/bin/activate

3. Install the AWS CDK, which is in the required Python dependencies:

pip install -r requirements.txt

Configure the Streamlit application

Complete the following steps to configure the Streamlit application:

1. In the docker_app directory, locate the config_file.py file.
2. Open config_file.py in your editor and modify the STACK_NAME and CUSTOM_HEADER_VALUE variables:
   1. The stack name enables you to deploy multiple applications in the same account. Choose a different stack name for each application. For your first application, you can leave the default value.
   2. The custom header value is a security token that CloudFront uses to authenticate on the load balancer. You can choose it randomly, and it must be kept secret.

Deploy the AWS CDK template

Complete the following steps to deploy the AWS CDK template:

1. From your terminal, bootstrap the AWS CDK:

cdk bootstrap

2. Deploy the AWS CDK template, which will create the necessary AWS resources:

cdk deploy

3. Enter y (yes) when asked if you want to deploy the changes.

The deployment process may take 5–10 minutes. When it’s complete, note the CloudFront distribution URL and Amazon Cognito user pool ID from the output.

Create an Amazon Cognito user

Complete the following steps to create an Amazon Cognito user:

1. On the Amazon Cognito console, navigate to the user pool that you created as part of the AWS CDK deployment.
2. On the Users tab, choose Create user.

3. Enter a user name and password.
4. Choose Create user.

Access the Streamlit application

Complete the following steps to access the Streamlit application:

1. Open a new web browser window or tab and navigate to the CloudFront distribution URL from the AWS CDK deployment output.

If you have not noted this URL, you can open the AWS CloudFormation console and find it in the outputs of the stack.

2. Log in to the Streamlit application using the Amazon Cognito user credentials you created in the previous step.

You should now be able to access and interact with the Streamlit application, which is deployed and running on AWS using the provided AWS CDK template.

This deployment is intended as a starting point and a demo. Before using this application in a production environment, you should thoroughly review and implement appropriate security measures, such as configuring HTTPS on the load balancer and following AWS best practices for securing your resources. See the README.md file in the GitHub repository for more information.

Customize the application

The aws-samples/deploy-streamlit-app GitHub repository provides a solid foundation for building and deploying generative AI applications, but it’s also highly customizable and extensible.

Let’s explore how you can customize the Streamlit application. Because the application is written in Python, you can modify it to integrate with different generative AI models, add new features, or change the UI to better align with your application’s requirements.

For example, let’s say you want to add a button to invoke the LLM answer instead of invoking it automatically when the user enters input text. Complete the following steps to modify the docker_app/app.py file:

1. After the definition of the input_sent text input, add a Streamlit button:

# Insert this after the line starting with input_sent = …
submit_button = st.button("Get LLM Response")

2. Change the if condition to check if the button is clicked instead of checking for input_sent:

# Replace the line `if input_sent:` by the following
if submit_button:

3. Redeploy the application by entering the following in the terminal:

cdk deploy

The deployment should take less than 5 minutes. In the next section, we show how to test your changes locally before deploying, which will accelerate your development workflow.

4. When the deployment is complete, refresh the webpage in your browser.

The Streamlit application will now display a button labeled Get LLM Response. When the user chooses this button, the LLM will be invoked, and the output will be displayed on the UI.

This is just one example of how you can customize the Streamlit application to meet your specific requirements. You can modify the code further to integrate with different generative AI models, add additional features, or enhance the UI as needed.

Test your changes locally before deploying

Although deploying the application using cdk deploy allows you to test your changes in the actual AWS environment, it can be time-consuming, especially during the development and testing phase. Fortunately, you can run and test your application locally before deploying it to AWS.

To test your changes locally, follow these steps:

1. In your terminal, navigate to the docker_app directory, where the Streamlit application is located:

cd docker_app

2. If you haven’t already, install the dependencies of the Python application. These dependencies are different from the ones of the AWS CDK application that you installed previously.

pip install -r requirements.txt

3. Start the Streamlit server with the following command:

streamlit run app.py --server.port 8080

This will start the Streamlit application on port 8080.

You should now be able to interact with the locally running Streamlit application and test your changes without having to redeploy the application to AWS.

Remember to stop the Streamlit server (by pressing Ctrl+C in the terminal) when you’re done testing.

By testing your changes locally, you can significantly speed up the development and testing cycle, allowing you to iterate more quickly and catch issues early in the process.

Clean up

To avoid incurring additional charges, clean up the resources created during this demo:

1. Open the terminal in your development environment.
2. Make sure you’re in the root directory of the project and your virtual environment is activated:

cd ~/environment/deploy-streamlit-app
source .venv/bin/activate

3. Destroy the AWS CDK stack:

cdk destroy

4. Confirm the deletion by entering yes when prompted.

Conclusion

Building and deploying user-friendly generative AI applications no longer requires extensive knowledge of frontend and backend development frameworks. By using Streamlit and AWS services, data scientists can focus on their core expertise while still delivering secure, scalable, and accessible applications to business users.

The full code of the demo is available in the GitHub repository. It provides a valuable starting point for building and deploying generative AI applications, allowing you to quickly set up a working prototype and iterate from there. We encourage you to explore the repository and experiment with the provided solution to create your own applications.

As the adoption of generative AI continues to grow, the ability to build and deploy user-friendly applications will become increasingly important. With AWS and Python, data scientists now have the tools and resources to bridge the gap between their technical expertise and the need to showcase their models to business users through secure and accessible UIs.

Generative AI continues to push the boundaries of what’s possible. One area garnering significant attention is the use of generative AI to analyze audio and video transcripts, increasing our ability to extract valuable insights from content stored in audio or video files. Speech data is unique and complex, which makes it difficult to analyze and extract insights. Manually transcribing and analyzing it can be time-consuming and resource-intensive.

Existing methods for extracting insights from speech data often require tedious human transcription and review. You can use automatic voice recognition tools to convert your audio and video data to text. However, you still have to rely on manual processes for extracting specific insights and data points, or get summaries of the content. This approach is time-consuming and as organizations amass vast amounts of this content, the need for a more efficient and insightful solution becomes increasingly pressing. There is a significant opportunity to add business value given the amount of data organizations store in these formats and the valuable insights that might otherwise go undiscovered. The following are some of the new insights and capabilities that can be obtained through the use of large language models (LLM) with audio transcripts:

• LLMs can analyze and understand the context of a conversation, not just the words spoken, but also the implied meaning, intent, and emotions. Previously, this would have required extensive human interpretation.
• LLMs can perform advanced sentiment analysis. Previously, sentiment analysis could be captured, but LLMs can capture more emotions, such as sarcasm, ambivalence, or mixed feelings by understanding the context of the conversation.
• LLMs can generate concise summarizations not just by extracting content, but by understanding the context of the conversation.
• Users can now ask complex, natural language questions and receive insightful answers.
• LLMs can infer personas or roles in a conversation, enabling targeted insights and actions.
• LLMs can support the creation of new content based on audio assets or conversations following predetermined templates or flows.

In this post, we examine how to create business value through speech analytics with some examples focused on the following:

• Automatically summarizing, categorizing, and analyzing marketing content such as podcasts, recorded interviews, or videos, and creating new marketing materials based on those assets
• Automatically extracting key points, summaries, and sentiment from a recorded meeting (such as an earnings call)
• Transcribing and analyzing contact center calls to improve customer experience.

The first step in getting these audio data insights involves transcribing the audio file using Amazon Transcribe. Amazon Transcribe is a machine learning (ML) based managed service that automatically converts speech to text, enabling developers to seamlessly integrate speech-to-text capabilities into their applications. It also recognizes multiple speakers, automatically redacts personally identifiable information (PII), and allows you to enhance the accuracy of a transcription by providing custom vocabularies specific to your industries or use case, or by using custom language models.

The second step involves using foundation models (FMs) with Amazon Bedrock to summarize the content, identify topics, and recognize conclusions, extracting valuable insights that can guide strategic decisions and innovations. Automatic generation of new content also adds value, increasing creativity and productivity.

Generative AI is reshaping the way we analyze audio transcripts, enabling you to unlock insights such as customer sentiment, pain points, common themes, avenues for risk mitigation, and more, that were previously obfuscated.

Use case overview

In this post, we discuss three example use cases in detail. The code artifacts are in Python. We used a Jupyter notebook to run the code snippets. You can follow along by creating and running a notebook in Amazon SageMaker Studio.

Audio summarization and insights, and automated generation of new content using Amazon Transcribe and Amazon Bedrock

Through this use case, we demonstrate how to take an existing marketing asset (a video) and create a new blog post to announce the launch of the video, create an abstract, and extract the main topics and the search engine optimization (SEO) keywords present in the post for documenting and categorizing the asset.

Transcribe audio with Amazon Transcribe

In this case, we use an AWS re:Invent 2023 technical talk as a sample. For the purpose of this notebook, we downloaded the MP4 file for the recording and stored it in an Amazon Simple Storage Service (Amazon S3) bucket.

The first step is to transcribe the audio file using Amazon Transcribe:

# Create a Amazon Transcribe transcirption job by specifying the audio/video file's S3 location
import boto3
import time
import random
transcribe = boto3.client('transcribe')
response = transcribe.start_transcription_job(
    TranscriptionJobName=f"podcast-transcription-{int(time.time())}_{random.randint(1000, 9999)}",
    LanguageCode='en-US',
    MediaFormat='mp3',
    Media={
        'MediaFileUri': '<S3 URI of the media file>'
    },
    OutputBucketName='<name of the S3 bucket that will store the output>',
    OutputKey='transcribe_bedrock_blog/output-files/',
    Settings={
        'ShowSpeakerLabels': True,
        'MaxSpeakerLabels': 3
    }
)
max_tries = 60
while max_tries > 0:
    max_tries -= 1
    job = transcribe.get_transcription_job(TranscriptionJobName=response['TranscriptionJob']['TranscriptionJobName'])
    job_status = job["TranscriptionJob"]["TranscriptionJobStatus"]
    if job_status in ["COMPLETED", "FAILED"]:
        if job_status == "COMPLETED":
            print(
                f"Download the transcript fromn"
                f"t{job['TranscriptionJob']['Transcript']['TranscriptFileUri']}."
            )
        break
    else:
        print(f"Waiting for {response['TranscriptionJob']['TranscriptionJobName']}. Current status is {job_status}.")
    time.sleep(10)

The transcription job will take a few minutes to complete.

When the job is complete, you can inspect the transcription output and check the plain text transcript that was generated (the following has been trimmed for brevity):

# Get the Transcribe Output JSON file
s3 = boto3.client('s3')
output_bucket = job['TranscriptionJob']['Transcript']['TranscriptFileUri'].split('https://')[1].split('/',2)[1]
output_file_key = job['TranscriptionJob']['Transcript']['TranscriptFileUri'].split('https://')[1].split('/',2)[2]
s3_response_object = s3.get_object(Bucket=output_bucket, Key=output_file_key)
object_content = s3_response_object['Body'].read()

transcription_output = json.loads(object_content)

# Let's see what we have inside the job output JSON
print(transcription_output['results']['transcripts'][0]['transcript'])

……….Once the alert comes, how do you kind of correlate these alerts, not by just text signals and text passing, but understanding the topology, the infrastructure topology that is supporting that application or that business service. It is the topology that ultimately gives the source of truth when an alert comes, right. That’s what we mean by a correlation that is assisted with topology in in in the thing that ultimately results in finding a probable root cause. And once ……….

After you have validated the existence of the text, you can use Amazon Bedrock to analyze the output:

# Now let's use this transcript to extract insights with a help of a Large Language Model on Amazon Bedrock
# First let's initialize the bedrock runtime client to invoke the model. 
bedrock_runtime = boto3.client('bedrock-runtime')
# Selecting Claude 3 Sonnet
model_id = 'anthropic.claude-3-sonnet-20240229-v1:0'

Using the transcription from the technical talk, we use Amazon Bedrock to call an FM (we use Anthropic’s Claude 3 Sonnet on Amazon Bedrock in this case). You can choose from the language models available on Amazon Bedrock from AI21 Labs, Anthropic, Cohere, Meta, Mistral AI, Stability AI, and Amazon.

You can now perform additional tasks.

Extract the main topics with Amazon Bedrock

The following prompt provides instructions to ask the LLM for the main topics in the technical talk:

# Extracting the main topics with Amazon Bedrock
main_topics_prompt = """Based on the contents of <transcript></transcript>, what are the main topics being discussed? Display the topics as a list.

<transcript>
{transcript}
</transcript>
"""

user_message = {"role": "user", "content": main_topics_prompt.format(transcript = transcription_output['results']['transcripts'][0]['transcript'])}

messages = [user_message]

body=json.dumps(
{
"anthropic_version": "bedrock-2023-05-31",
"max_tokens": 1000,
"messages": messages
}
)
bedrock_response = bedrock_runtime.invoke_model(body=body, modelId=model_id)
response_body = json.loads(bedrock_response.get('body').read())
main_topics = response_body['content'][0]['text']
print(main_topics)

We have created a prompt that uses prompting best practices for Anthropic’s Claude. In this case, we pass the transcript within the <transcript></transcript> XML tags and ask for main topics discussed. Based on that, we get the following output:

Based on the contents of the transcript, the main topics being discussed are:

1. AI and Machine Learning in IT Operations
2. Challenges faced by IT Operations teams
3. Observable data explosion from cloud, on-premise, and edge infrastructure
4. The convergence of IT, SRE, and DevOps roles
5. Discovery to Resolution pipeline for IT Operations
6. Alert correlation and intelligent alerting using AI/ML
7. Probable root cause analysis with AI/ML
8. Automated remediation and runbook automation
9. Predictive analytics and preventive maintenance using AI/ML
10. Benefits of AI/ML for IT Operations (proactive operations, reduced human effort, improved service health, cost optimization)

Generate a blog post to announce the video with Amazon Bedrock

The following prompt provides instructions to ask the LLM for the generation of a new blog post announcing the launch of the preceding recording. Just like the preceding prompt, we use prompting best practices for Anthropic’s Claude:

# Generating a blog post to announce the Podcast with Amazon Bedrock
generate_blog_prompt = """The contents of <transcript></transcript> are a transcription of a technical talk video recording. Based on this information write a blogpost that summarizes the technical talk and announces that the recording of this talk is now available for public consumption. Limit the blogpost to 1500 words.

user_message =  {"role": "user", "content": generate_blog_prompt.format(transcript = transcription_output['results']['transcripts'][0]['transcript'])}

messages = [user_message]

body=json.dumps(
    {
        "anthropic_version": "bedrock-2023-05-31",
        "max_tokens": 1000,
        "messages": messages
    }
)
bedrock_response = bedrock_runtime.invoke_model(body=body, modelId=model_id)
response_body = json.loads(bedrock_response.get('body').read())
generate_blog = response_body['content'][0]['text']
print(generate_blog)

Based on that, we get the following output:

Here is a draft 1462 word blogpost summarizing the technical talk and announcing the recording is now available:

Title: Revolutionizing IT Operations with AI/ML: A Future-Ready Approach

Extract SEO keywords from the generated blog post with Amazon Bedrock

The following prompt provides instructions to extract the main SEO keywords from the generated blog post. Based on online research on how to extract SEO keywords from long-form text, we came up with the following list. This demonstrates how you can empower an LLM like Anthropic’s Claude to follow instructions and best practices for a particular task or domain. Also, the prompt specifies that the output should be in JSON. This is helpful in use cases where you want to programmatically get results from an LLM and therefore require consistent formatting. Based on best practices for Anthropic’s Claude, we use the Assistant message in the messages API to pre-fill the model’s response to have further control on the output format:

# Extracting SEO keywords from the generated blog post
SEO_keywords_prompt = """Extract the most relevant keywords and phrases from the given blog post text present in <blog></blog> that would be valuable for SEO (search engine optimization) based on the instructions present in <instructions></instructions> below. The ideal keywords should capture the main topics, concepts, entities, and high-value terms present in the content. Use JSON format with key "keywords" and value as an array of keywords. Skip the preamble; go straight into the JSON.

Title: Unleash the Power of AI-Driven and Machine Learning IT Operations for Proactive IT Operations

In today’s rapidly evolving digital landscape, traditional IT operations approaches are struggling to keep pace. The explosion of data from cloud workloads, Kubernetes clusters, and distributed edge locations has overwhelmed conventional monitoring tools, leading to fragmented views and reactive operations that respond to issues after they occur. To stay ahead of the curve, organizations must embrace AI-driven and machine learning IT operations, paving the way for proactive IT operations that enhance efficiency and minimize downtime.

At a recent technical talk, Verma and Radha Krishna Kunni from OpsRamp (recently acquired by HPE) delved into the transformative impact of AI and machine learning on IT operations, DevOps, and SRE for hybrid multi-cloud environments. They highlighted the key challenges ops teams face today and introduced the innovative “FutureOps” approach, which leverages AI and machine learning to revolutionize IT operations.

Summarize content discussed in a recorded meeting using Amazon Transcribe and Amazon Bedrock

Through this use case, we demonstrate how to take an existing recording from a meeting (we use a recording from an AWS earnings call) to summarize the content discussed, extract the key points, and provide details on the sentiment of the meeting. For additional information on this use case, see Live Meeting Assistant with Amazon Transcribe, Amazon Bedrock, and Amazon Bedrock Knowledge Bases or Amazon Q Business.

Transcribe audio with Amazon Transcribe

In this use case, we use an Amazon 2024 Q1 earnings call as a sample. For the purpose of this notebook, we downloaded the WAV file for the recording and stored in an S3 bucket.

The first step is to transcribe the audio file using Amazon Transcribe:

# Create a Amazon Transcribe transcription job by specifying the audio/video file's S3 location
import boto3
import time
import random

Thank you for standing by. Good day, everyone and welcome to the amazon.com first quarter, 2024 financial results teleconference. At this time, all participants are in a listen only mode. After the presentation, we will conduct a question and answer session. Today’s call is being recorded and for opening remarks, I’ll be turning the call over to the Vice President of Investor………

After you have validated the existence of the text, you can use Amazon Bedrock to analyze the output:

# Now let's use this transcript to extract insights with a help of a Large Language Model on Amazon Bedrock
# First let's initialize the bedrock runtime client to invoke the model. 
bedrock_runtime = boto3.client('bedrock-runtime')
# Selecting Claude 3 Sonnet
model_id = 'anthropic.claude-3-sonnet-20240229-v1:0'

Using the transcription from the earnings call recording, we use Amazon Bedrock to call an FM (we use Anthropic’s Claude 3 Sonnet in this case). You can choose from other FMs available on Amazon Bedrock.

You can now perform additional tasks.

Based on this, we get the following output:

Based on the earnings call transcript, the following financial ratios and their implications were highlighted:

1. Operating Income Margin:
   • Amazon reported its highest ever quarterly operating income of $15.3 billion, which was $3.3 billion above the high end of their guidance range. This was driven by strong operational performance across all three reportable segments (North America, International, and AWS) and better-than-expected operating leverage, including lower cost to serve.
   • North America segment operating income was $5 billion with an operating margin of 5.8%, up 460 basis points year-over-year, driven by improvements in cost to serve, including benefits from regionalization efforts, more consolidated customer shipments, and improved leverage.
   • International segment operating income was $903 million with an operating margin of 2.8%, up 710 basis points year-over-year, primarily driven by cost efficiencies through network design enhancements and improved volume leverage in established countries, as well as progress in emerging countries.
   • AWS operating income was $9.4 billion, an increase of $4.3 billion year-over-year, with improved leverage from managing infrastructure and fixed costs while growing at a healthy rate.

Implication: The higher operating income margins across all segments indicate Amazon’s focus on driving efficiencies and improving profitability while continuing to invest in growth opportunities.

2. Revenue Growth:
   • Worldwide revenue was $143.3 billion, up 13% year-over-year (excluding the impact of foreign exchange).
   • AWS revenue grew 17.2% year-over-year, accelerating from 13.2% in Q4 2023, driven by strong demand for both generative AI and non-generative AI workloads.
   • Advertising revenue grew 24% year-over-year (excluding the impact of foreign exchange), primarily driven by sponsored products and improvements in relevancy and measurement capabilities.

Implication: The strong revenue growth, particularly in AWS and advertising, highlights Amazon’s diversified revenue streams and the growth opportunities in cloud computing and digital advertising.

3. Capital Expenditures (Capex):
   • Amazon anticipates a meaningful increase in overall capital expenditures in 2024, primarily driven by higher infrastructure Capex for growth in AWS, including generative AI investments.
   • In Q1 2024, Capex was $14 billion, expected to be the lowest quarter of the year.

Implication: The increase in Capex signals Amazon’s confidence in the strong demand for AWS and their commitment to investing in emerging technologies like generative AI to drive future growth.

Overall, the financial ratios and commentary indicate Amazon’s focus on improving profitability, driving operational efficiencies, and investing in growth opportunities, particularly in AWS and generative AI, while maintaining a diversified revenue stream and managing costs effectively.

1. Foreign exchange headwinds: Amazon faced an unfavorable impact from global currencies weakening against the U.S. dollar in Q1, leading to a $700 million or 50 basis point headwind to revenue compared to guidance.
2. Increasing capital expenditures: Amazon expects to meaningfully increase its capital expenditures year-over-year in 2024, primarily driven by higher infrastructure spending for AWS growth, including investments in generative AI capabilities.
3. Consumer spending concerns: Amazon mentioned keeping an eye on consumer spending trends, specifically in Europe, where it appears weaker relative to the U.S.
4. International segment profitability: While the international segment’s profitability improved, with an operating margin of 2.8%, Amazon acknowledged the need to continue working on cost efficiencies and profitability, particularly in emerging countries.
5. Cost optimization challenges: Although Amazon believes the majority of cost optimization efforts are behind them, there is still a need to continually streamline processes, optimize inventory placement, and invest in automation to further reduce the cost to serve.

Overall, the challenges centered around foreign exchange impacts, increasing capital intensity for AWS and generative AI investments, consumer demand uncertainties, and ongoing efforts to improve operational efficiencies and international profitability.

Thank you for calling Big Jim’s Auto. This is Travis. How can I help you today? Hello, my name is Violet King and I bought a car not too long ago and a light is coming on um a light on the dashboard. And so I was wondering what I should do about that. Ok. It may depend on what kind of light we’re looking at here today, ma’am. Uh Could I get your first and last name spelled out for me so I can just get some information pulled up? Yes. My name is Violet Vviolet. My last name is King King. Ok, I got the call last week. Ok. Uh And what kind of car are we examining today? It’s, it’s a Ford Fusion. It’s 2017, 2017 Ford Fusion. OK. And for verification, ma’am. Do you happen to know the purchase date of the car? Yes, it, it, it was last Tuesday, August 10th. You say the 10th? Ok. And can you describe to me what kind of light we’re looking at? Y yes, it’s uh I, I think it’s a, an oil, an oil light, an oil light? Ok. Ok. And uh just for clarity on my end, ma’am. Um, uh, is this the first call you’ve made regarding this? Yes. Ok. And, uh, this might be kind of a silly question because I know you just got the car. But sometimes they make me ask a silly question about how many miles has the car been driven since you bought it? Oh. I’m not sure. Should I check? Uh, no, that’s ok. I’ll just, I’ll just put in that. We don’t know at this time. It’s ok. Um, so, um, uh, under the warranty we offer, um, we, the, we don’t handle in house oil changes. Um, we basically, when, when someone buys a car from us, the warranty, we have, it, it covers some stuff like, um, weather damage. Um, and, uh, if the engine light comes on, we take a look at that, but the oil change is something that we just don’t have, uh, here at the dealership that’s a little bit outsourced out and they’re pretty backed up right now because a lot of people have been, uh, staying in due to the recent pandemic and now everyone’s just starting to get out and a whole bunch of places are just completely bogged down. So we have a place that we typically outsource to, um, and they’re, they’re pretty reasonable. They’re about, I wanna say somewhere between 25 and $35 to do an oil change. So it’s really not that bad, but they’re a little bit backed up right now from what I’ve heard, I would recommend giving them a call as soon as you can before they close. Ok. What is their number? Uh, give me a second. Let me just rustle through the desk here. See if I can find their information. Uh, ok. Ok. Yes, I’m all right with them one moment, please. Sure. Ok. All their number is 888 333 2222. Ok, and they can fix my car. Yeah, they should be able to handle the oil change. I’m sorry, that’s not something that we cover under the warranty that uh, we have, um, but they should be able to get you settled and, uh, sorted. Ok. Ok. Thank you. Cool. No problem. Have a good one. Thank you. Yup. Bye.

Based on the contents of the transcript, here is a summary of the call between the agent (Travis) and the customer (Violet King) with a focus on resolution:

Violet King called about a light on the dashboard of her recently purchased 2017 Ford Fusion from Big Jim’s Auto. The light appeared to be an oil light. Travis explained that while their warranty covers certain issues like weather damage and engine lights, it does not cover oil changes. He recommended calling an outsourced oil change service that Big Jim’s Auto typically uses, which charges between $25-35 for an oil change.

Travis provided the phone number for the oil change service (888-333-2222) and mentioned that they are currently backed up due to the recent pandemic. He advised Violet to call them as soon as possible before they close to get her oil changed and resolve the issue with the oil light on her dashboard.

The resolution was for Violet to contact the recommended third-party oil change service to have her car’s oil changed, which should address the oil light issue she was experiencing with her newly purchased vehicle.

Dear Ms. Violet King,

I hope this email finds you well. I’m writing to summarize our conversation regarding the issue with your 2017 Ford Fusion that you purchased last Tuesday, August 10th.

During our call, you mentioned that an oil light was illuminated on the dashboard of your vehicle. As discussed, our dealership’s warranty does not cover routine maintenance services like oil changes. However, we have a trusted partner that we typically recommend for such services.

The recommended auto service provider is reachable at 888-333-2222. They are experienced in handling oil changes and should be able to assist you with your vehicle’s needs. Please note that they have been experiencing a high volume of requests due to the recent pandemic, so it’s advisable to call them as soon as possible to schedule an appointment.
