The Known and Unknown of Amazon Q Developer

Lydia Dely — Tue, 03 Sep 2024 16:25:57 +0000

When Amazon Q Developer was first announced at the re:Invent 2023 in Las Vegas, NV, I felt like I had finally found what I had been looking for throughout my entire career as a DevOps Engineer in SRE. I couldn't wait to get my hands dirty and meet this amazing best friend of mine "in person" as I immediately knew this buddy (available 24/7 only for me) will save me hours of a day's work.

Amazon Q Developer is part of Amazon Q family which is generative AI powered assistant for software development (Amazon Q Developer) and company knowledge (Amazon Q Business), and in this blog, I'll dive deep into Amazon Q Developer.
By the way, did you know why it's called Q? Q is short for 'Question,' but it also calls to mind fictional characters from both Star Trek and James Bond who are known for their power, resourcefulness, and expertise.

Statistics and Facts
Organizations want to enable employees with generative AI as productivity improves more than 30% on average.

More than 80% of enterprises will have used generative AI APIs or deployed generative AI-enabled apps by 2026.
*According to Gartner, October 2023

How much time do developers spend coding?
Software.com analyzed data from more than 250 000 developers worldwide over a 3 month period, and they found that:

the median time that developers spend writing or editing code in their IDE is less than an hour per day (52 minutes),
per work week, developers spend less than 4 1/2 hours writing code,
only 10 % of developers spend more than 2 hours per day coding.

Amazon Q Developer vs. Amazon CodeWhisperer

Maybe you think now: "OK, but isn't it the same as Amazon CodeWhisperer?"

CodeWhisperer is where we got started [with code generation], but we really wanted to have a brand - and name - that fit a wider set of use cases.
(Doug Seven, Director, GM @ AWS| AWS AI Developer Experiences)

All of the features of CodeWhisperer were moved to Amazon Q Developer in April 2024, that means CodeWhisperer is now Amazon Q Developer. In addition, there are some more features of Amazon Q Developer that weren't available in CodeWhisperer, such as:

diagnosing console errors (with Amazon Q),
transforming your code with Amazon Q Developer agents for transformation,
developing software with Amazon Q Developer agents for software development,
chatting about your costs (retrieve and analyze cost data from AWS Cost Explorer),
chatting about your resources (list, describe, and get guidance based on resources in your AWS account).

By including @workspace in yur prompt, Amazon Q Developer will automaticaly ingest and index all code files, configurations and project structure

UPDATE Recently announced

How does /transform work?

Open Amazon Q chat in your IDE and type /transform.

Amazon Q Developer code transformation recieved new CLI tool (public preview).
UPDATE Recently announced

It will automatically prompt to upgrade Java as follows (example for upgrade to Java17):

Then you need to add path to your Java code and your transformation starts. It takes usually up to 30 mins.

/dev Looking at this project, can  you tell me which version of java this project is using?
/usr/libexec/java_home -V #Current java varsion
/usr/libexec/java_home -v 1.8 #Path to java8 (need to update ~/.zshrc or ~/.bash_profile #depends what you are using in your IDE terminal)

#if MAC:
brew tap adoptopenjdk/openjdk
brew install --cask adoptopenjdk8
brew install maven

Below you can see newly generated Code Transformation plan by Amazon Q and Code Transformation Summary by Amazon Q.

Java has been successfully upgraded even you can see some red flags.
The reason why upgrade succeeded is that during the process Gen AI fixed errors itself.

At the end we can review our pom.xml file before and after upgrade.

Amazon has migrated tens of thousands of production applications from Java 8 or 11 to Java 17 with assistance from Amazon Q Developer. This represents a savings of over 4,000 years of development work for over a thousand developers (when compared to manual upgrades) and performance improvements worth $260 million dollars in annual cost savings.

Don't forget to verify your new created tests by following command:
mvn verify -f "PATH to pom.xml file" or as follows

It will automatically prompt to upgrade Java as follows (example for upgrade to Java21):

Amazon Q Developer Agent for software development

Amazon Q Developer has an agent for software development (type /dev in chat window) that can autonomously perform a range of tasks–everything from writing and implementing entire application features in minutes right from a simple natural language prompt in your IDE.

This agent got new capabilities, such:
- enhanced documentation in codebases (type /doc in chat window),
- supporting code reviews to detect and resolve security and code quality issues (type /review in chat window),
- generating unit tests automatically and improving test coverage (type /test in chat window).

UPDATE Recently announced

Developers can collaborate with the agent to review and iterate on the plan before the agent implements it, connecting multiple steps together and applying updates across source files, code blocks, and test suites.

How does /doc work?
Type /doc in IDE Q chat window and choose if you want to create new README or update an existing README.

After you choose an existing README, you can select from update README to reflect code or make a specific change.

Then approve project by clicking on YES button or write specific change.

How does /test work?
Type /test in IDE Q chat window and write your description. This agent support only tests (Java and Python) for selected code.

How does /review work?
Type /review in IDE Q chat window to identify and fix code issues before committing. Then you can choose if you want to scan whole project (workspace) or active file only.

Scan detects security vulnerabilities, scans for secrets, and assesses the security of your infrastructure as code files. You can scan an entire codebase or you can analyze your code as you write it using automatic scans.
For example, it might detect resource leaks, SQL injection, hardcoded database connection strings, infrastructure as code misconfiguration, and more.

After it scans your code it will provide you with a list of security issues found in your files.

You can then select each problem detected in the list of issues. It will take you to the line in your code where it found the issue. You can then hover over the line and see more details about the problem.

Sometimes you can see fix your issue button that is only available for certain issues. This option is an automatic code fix. The description will show that there’s a code fix available, and you can select this fix and it will directly update your code for you.

How does /dev work?

Type /dev in IDE Q chat window and describe your task or feature in as much detail as possible.

Once the /dev command is entered in the IDE, the agent packages the project and securely uploads it to Amazon Q, initiating project-specific code generation. The Amazon Q Developer agent not only focuses on code generation, but also maintains a real-time connection with the developer, providing updates throughout the process and delivering a polished patch or implementation for the requested feature.

This real-time execution is powered by a Devfile, which defines the development environment and commands the agent can use. If a project doesn’t already have a Devfile, Amazon Q Developer will prompt users to create one after their first run of /dev. Without a Devfile, the agent will develop solutions without the additional feedback provided by running builds or unit tests, limiting developers’ ability to receive real-time feedback during the development process.

The Devfile must conform to the Devfile 2.2.0 schema. Currently, Amazon Q Developer supports the install, build, and test commands.

Core enhancements in the latest Amazon Q Developer update

Customizable Commands: Developers can specify commands in a Devfile to control which commands the AI agent runs, reducing unnecessary steps and improving accuracy.
Flexible Environment Setup: Developers can use custom Docker images preloaded with dependencies for faster startup times, providing the agent has all necessary tools.
Sandboxed Security: Amazon Q Developer secures the execution within isolated environments, offering comprehensive logging and robust permission controls to safeguard any changes made.

With this setup, Amazon Q Developer can execute tests, apply migrations, and run installation commands directly within a sandbox, providing feedback to the agent for iterative improvements.

Customers have reported efficiency improvements of 25% faster initial development and up to a 40% increase in developer productivity.

Explain code with conversational coding

This is especially useful for new developers who may have just inherited a legacy code base and who may have questions about what some of the various code modules do.

As you can see, there is much more you can do, such as:

Refactor Code for Code Readability: Improve the readability of a specific code module by refactoring it. Break down complex functions into smaller, more manageable units, and apply meaningful variable and function names for better clarity.
Optimising your code can help you towards cost and sustainability goals, and so may provide you with some good options.
and many more...

Amazon Q Developer in the AWS Management Console

Ask questions and get guidance from 17 years of AWS knowledge, best practices, well-architected advice (best practices, AWS WAF, Amazon EC2 instance optimization).

You can also tetrieve and analyze cost data from AWS Cost Explorer (in preview).

Inline coding companion in IDE and CLI

How does this kind of coding work?

based on your natural language prompt,

generate up to 5 suggestions (Tab for accept, Arrows for moving between suggestions),

by pressing Enter Q Developer generates code for you based on your private repositories.

Plus
I find this very helpful because if I were to write the code manually, I would have had to look up some of the exact wording and syntax, which would have taken me much longer and potentially could have been less accurate.
Even though the generated code need some manual fixes to meet IaC best practices, it still can save developers a lot of time.

Cons
You really need to know where your code is going for Q Developer to be helpful, though. Sometimes, Q Developer might get it wrong, suggest something you're not looking for, or not follow common coding best practices, so you need to stay focused. This tool isn't a replacement for a programmer and to get the most out of it, you need to know what you want your code to look like so you can pick the right suggestions from Q Developer.

EC2 instance type suggestion

Amazon Q can help you with choosing right instance type while creating EC2 instance.

Troubleshooting

Amazon Q Developer has expanded its AWS Console error coverage from US East (N. Virginia) and US West (Oregon) to AWS Commercial regions. Users can now troubleshoot AWS Console errors using Amazon Q Developer regardless of their console region, including locations like Europe (Frankfurt).
UPDATE Announced on February 2024

Troubleshoot errors from the following services - Amazon S3, AWS Lambda, Amazon EC2, Amazon Elastic Container Service and

also Amazon CloudFormation.
UPDATE Recently announced

Troubleshoots IAM Permission and Athena console errors across all AWS Console pages.

AWS announced a new capability to investigate and remediation operational issues, which seamlessly integrated into Amazon CloudWatch and AWS Systems Manager UPDATE Recently announced

Lambda troubleshooting example This is my fave! I have written basic lambda for creating object in S3 bucket with some text. While testing it I've got an error. What now?

Just click on Diagnose with Q and Q will help to troubleshoot.

So I was missing inline policy, fixed it and rerun test and test succeeded.

VPC Reachability Analyzer troubleshooting example

In case you are experiencing a network problem, you can ask in AWS Management Console for help. It will forward you to network troubleshooting chat.

Q will help you identify and fix the issue.

Conclusion and Findings

I believe that Q will become part of every aspect of how developers complete development tasks. Across Research, Design, Test and Maintain. From how developers find the information they need and how they understand code, to writing the actual code and figuring out bugs, all the way to doing the code reviews. Q will even brainstorm with developers how to improve applications. With Q, developers can spend more time building, innovating and experimenting.

Like all new tools, we need to learn how to get the best of them.

PS: If you're looking for information on Amazon Q Developer Security and couldn't find it, it's because I wrote a separate article on the topic. Check it out here.

Is Amazon Q Developer Secure?

Lydia Dely — Tue, 20 Aug 2024 19:54:46 +0000

Amazon Q is built with security and privacy in mind from the start, making it easier for organizations to use generative AI safely.

In this blog, I'll compile all the information regarding the security of data you send to Amazon Q Developer in one place.

1. Data Protection

The AWS shared responsibility model applies to data protection in Amazon Q Developer. AWS is responsible for protecting the global infrastructure that runs all of the AWS Cloud. You are responsible for maintaining control over your content that is hosted on this infrastructure. You are also responsible for the security configuration and management tasks for the AWS services that you use.

Regardless of where you use Amazon Q Developer, data is sent to and stored in an AWS Region in the US.
Your conversations with Amazon Q are stored in the US East (N. Virginia) Region even if the AWS Management Console is set to a different AWS Region.
Data processed during troubleshooting console error sessions is stored in the US West (Oregon) Region.
Data processed during interactions with Amazon Q in integrated development environments (IDEs) is stored in the US East (N. Virginia) Region.

2. Service Improvements

If you’re using the Pro version, it will not store or use any of your codebase to maintain or improve the service.
If you’re using the free version of Q Developer, this input/output combination, which includes the snippets Q Developer generates and the customer file contents, as well as chat conversations, may be stored in the Q Developer service and used for service improvement.

The idea is that Q Developer can use this data to improve the performance of the service over time. However, if privacy is a concern, you can choose to turn off this default behaviour to ensure that Q Developer does not use your information to maintain the service.
You can turn it off manually in your IDE, as you can see at the picture below (VSCode).

3. Data Encryption

3.1 Encryption in transit

All communication between customers and Amazon Q and between Amazon Q and its downstream dependencies is protected using TLS 1.2 or higher connections.

3.2 Encryption at rest

Amazon Q stores data at rest using Amazon DynamoDB and Amazon Simple Storage Service (Amazon S3). The data at rest is encrypted using AWS encryption solutions by default. Amazon Q encrypts your data using AWS owned encryption keys from AWS Key Management Service (AWS KMS). You don’t have to take any action to protect the AWS managed keys that encrypt your data.

For data stored by Amazon Q in IDEs, you can create your own customer managed AWS KMS key to encrypt your data at rest. Customer managed keys are KMS keys in your AWS account that you create, own, and manage to directly control access to your data by controlling access to the KMS key.

3.3 Encryption with the Amazon Q Developer Agent for code transformation

When you begin a transformation with the Amazon Q Developer Agent for code transformation, your code is sent to a service-owned Amazon S3 bucket over an encrypted TLS connection. Your code is encrypted at rest with a customer managed key if you provide one, and otherwise with an AWS-owned key. During the transformation, your code is stored in memory in a secure build environment. After the transformation has completed, the build environment is deleted and any artifacts are flushed from memory. Your encrypted code remains in the service-owned Amazon S3 bucket for up to 24 hours, and then is permanently deleted.

3.4 Encryption with Customizations

When you create a customization, Amazon Q uploads your files to a service-owned Amazon S3 bucket. Your files are encrypted in transit with HTTPS and TLS. They are encrypted at rest with a customer managed key if you provide one, and otherwise with an AWS-owned key. Once your customization has been created, AWS permanently deletes your data from the bucket, and purges it from memory.

Your customizations are fully isolated from each other within your account. They are also isolated from the data of other customers. Only users specified by a Amazon Q Developer administrator have access to any specific customization. Before a Amazon Q administrator can specify which users can access which customizations, you must authorize that administrator permission to do so.

4. Reference tracker

Amazon Q Developer was trained using open source and Amazon-specific code in order to generate these code snippets based on your contextual data.
Technically, if you accept a suggestion from Q Developer, you still own that code plus any code you create yourself. However, there may be times when Q Developer generates code that closely matches code that it was trained on.

If Q Developer detects that this is the case, and they’re giving you essentially plagiarized code, then the reference tracker kicks in. The reference tracker is built-in to the Q Developer service to notify you when code snippets match publicly available data. It does this by providing a reference to the license information and to the URL of the open-source training data. That way you can review the code and save yourself from a murky legal situation if needed.

If you don’t want any code snippets that match publicly available data, then you can turn off a setting to “Include Suggestions With Code References”. This is turned on by default, but you can toggle it to ensure that you don’t have any code snippet suggestions that have references.

Conclusion

In wrapping up, I believe the security features offered by Amazon Q Developer are truly impressive and set a high standard in the industry. The commitment to data protection, through sophisticated encryption and ongoing service enhancements, reflects a deep understanding of the challenges developers face today.

The inclusion of reference tracking is a particularly thoughtful touch, showing that Amazon is not just focused on keeping your data secure, but also on streamlining your workflow.

Personally, I find these features reassuring, knowing that Amazon Q Developer is not just about powerful tools, but also about ensuring that the integrity and security of my work are maintained at all times. It’s clear that Amazon has taken the necessary steps to make sure we can focus on creating, without worrying about the security of our data.

What are the steps to integrate AWS services with a Streamlit application?

Integrating AWS services with a Streamlit application involves several steps, and the specific steps may vary depending on the AWS services you want to use and the requirements of your application. Here's a general guide to get you started:

set up AWS account,
install required libraries (make sure you have the necessary Python libraries installed like boto3 for AWS SDK and other libraries based on your application's requirements)

pip install streamlit boto3

AWS SDK configuration (set up AWS SDK (boto3) with your credentials. You can either configure it with environment variables or using the AWS CLI.)

import boto3

# Configure AWS SDK
aws_access_key_id = 'your_access_key_id'
aws_secret_access_key = 'your_secret_access_key'
aws_region = 'your_region'

boto3.setup_default_session(
    aws_access_key_id=aws_access_key_id,
    aws_secret_access_key=aws_secret_access_key,
    region_name=aws_region
)

integrate AWS services (depending on your application's requirements, you might integrate services like Amazon S3 for storage or other AWS services)

import boto3
import streamlit as st

# Function to upload file to S3
uploaded_file = st.sidebar.file_uploader("Choose a file", type=["txt","jpg","png","pdf"])
def upload_to_s3(file_path, bucket_name, object_name):
        s3 = boto3.client('s3')
        try:
            s3.upload_file(file_path, bucket_name, object_name)
            return True
        except Exception as e:
            st.error(f"An error occurred: {e}")
            return False

st.info(f"Updating file '{filename}' to S3 bucket '{bucket_name}'...")
        if upload_to_s3(temp_file.name, bucket_name, object_name):
            st.success(f"File '{filename}' uploaded successfully to S3 bucket: s3://{bucket_name}/{object_name}")        
        else:
            st.error(f"Failed to upload '{filename}' to S3 bucket '{bucket_name}'")

📝 securely manage credentials (avoid hardcoding credentials in your code, instead, employ IAM roles and permissions for better security, leverage AWS Secrets Manager _or _Parameter Store to securely store sensitive information)

📝 streamlit application (develop your Streamlit application as you normally would, utilizing Streamlit widgets to interact with your application and display relevant information)

📝 testing and deployment (test your application locally to ensure everything is working as expected)

📝 monitoring and logging (use CloudWatch or other relevant AWS services)

Utilizing AWS GenAI Services in a Streamlit App

Generative AI, a subset of artificial intelligence, empowers applications to create new content, such as images, text, or even entire narratives, by learning patterns from existing data. Integrating Generative AI services into a Streamlit app adds a creative and dynamic dimension to user interactions. Whether generating text, images, or other forms of content, these services open up innovative possibilities for enhancing user engagement.

How can AWS GenAI Services be incorporated into a Streamlit app?

Integrating GenAI services into your Streamlit applications can elevate user experiences and provide advanced functionality.

As shown in the examples below, these services can help streamline processes, increase user engagement, and make your Streamlit apps more competitive in today's tech landscape.

Image Recognition with GenAI Vision

GenAI Vision is a powerful service that can recognize objects, scenes, and text in images. Let's say you're building an e-commerce application that allows users to upload product images. You can enhance this functionality by integrating GenAI Vision to automatically identify and tag objects within the images.

In the example above, GenAI Vision has identified and tagged objects in an uploaded image, making it easier for users to categorize and search for products.

Natural Language Processing with GenAI Language

GenAI Language can be a valuable addition to Streamlit applications that involve text analysis or generation. Imagine you're creating a sentiment analysis tool for social media posts. By incorporating GenAI Language, you can provide more accurate sentiment analysis and even generate suggestions for improving text.

In this example, GenAI Language has analyzed a user's tweet and provided sentiment analysis along with suggestions for a more positive tone.

Enhancing Data Visualization with GenAI Data

If your Streamlit application deals with data visualization, GenAI Data can help improve the quality and appeal of your charts and graphs. Whether it's generating realistic data for testing or enhancing visualizations with intelligent data transformation, GenAI Data can save time and make your app more engaging. GenAI Data has transformed raw data into a visually appealing chart, making it easier for users to grasp the information.

Voice Commands and Responses with GenAI Voice

Adding voice commands and responses to your Streamlit application can greatly enhance accessibility and user interaction. GenAI Voice can help create conversational interfaces, making your app more user-friendly.

In this example, a Streamlit application uses GenAI Voice to respond to voice commands, providing a hands-free and convenient experience for users.

Benefits and Limitations

Using Streamlit in combination with AWS GenAI Services provides several benefits, particularly when compared to more comprehensive solutions like AWS Amplify. Here are some of the major advantages:

Ease of Use and Rapid Prototyping

Streamlit: It is incredibly user-friendly for data scientists and developers who are more comfortable with Python. Streamlit allows for rapid prototyping; you can create a working prototype with interactive features quickly.
AWS Amplify: While Amplify provides a full-stack development environment, it has a steeper learning curve, especially for those who are not as familiar with JavaScript or full-stack development practices.

Flexibility and Customization

Streamlit: It offers a high degree of flexibility, allowing developers to integrate various Python libraries and AWS services as needed. You can tailor your app specifically to your data visualization and processing needs.
AWS Amplify: Amplify is opinionated in its approach and is designed to work well within the AWS ecosystem. This can sometimes limit customization options, particularly for complex or unique backend requirements.

Cost Efficiency

Streamlit: Running Streamlit on an AWS instance incurs the cost of the instance itself. However, there are no additional charges for the Streamlit framework, which can be a cost-efficient solution for lightweight applications.
AWS Amplify: Amplify has a pricing model that includes costs for backend services, hosting, and other features. While it offers a free tier, costs can grow as your application scales or as you use more of the Amplify suite.

Python-Centric Development

Streamlit: Ideal for Python developers, Streamlit is a natural choice for teams that are already invested in Python for data science and analytics.
AWS Amplify: Amplify is more focused on JavaScript/TypeScript and the broader AWS service ecosystem, which can be a barrier for Python-centric teams.

Integration with AWS Services

Streamlit: While not as tightly integrated as Amplify, Streamlit can still easily connect to AWS services, including GenAI. This is especially powerful when leveraging AWS's machine learning services for data-intensive applications.
AWS Amplify: Amplify is designed to work seamlessly with AWS services, offering built-in components and CLI tools to connect to AWS backends.

Community and Support

Streamlit: It has a growing community, especially among data scientists. The support for data-centric operations is strong, with many resources available.
AWS Amplify: Amplify is backed by AWS and has extensive documentation and community support, including first-party support from AWS.

Deployment and Hosting

Streamlit: Can be deployed on various AWS services such as EC2, Elastic Beanstalk, or even a container service like ECS or EKS, giving developers flexibility in their deployment strategy.
AWS Amplify: The deployment is tightly integrated with the AWS ecosystem, which might be more straightforward but also ties your deployment closely to AWS.
