AWS Weekly Roundup: Kiro, Lambda Debugging, ECS Blue/Green, Bedrock AgentCore, and More (July 21, 2025)
Major AWS Updates You Can’t Miss: New Tools for Security, Lambda, ECS, and AI
Keeping up with the pace of innovation at Amazon Web Services can feel like a full-time job. Every week brings a fresh wave of updates that can significantly impact how you build, deploy, and secure your applications. This week is no exception, with major announcements spanning cloud security, serverless computing, container deployments, and generative AI.
Whether you’re a developer, a security professional, or a cloud architect, these new features offer powerful capabilities to enhance your workflows. Let’s dive into the most important updates and what they mean for your infrastructure.
Strengthen Your Security Posture with Kiro
In the world of cloud computing, security isn’t just a feature—it’s the foundation. Misconfigurations remain one of the leading causes of security vulnerabilities. To combat this, AWS has introduced Kiro, a new open-source tool designed to proactively detect security issues in your cloud environment.
Kiro functions as a powerful scanner that analyzes your infrastructure for common misconfigurations, security vulnerabilities, and deviations from best practices. Think of it as an automated security auditor working for you 24/7.
Key Benefit: By integrating Kiro into your development and deployment pipelines, you can catch potential security flaws before they reach production. This shifts security left, making it an integral part of your development lifecycle rather than an afterthought.
Actionable Tip: We recommend security teams and platform engineers install Kiro and run an initial scan against their development environments. The insights gained can provide a clear roadmap for immediate security hardening and help you establish a more robust baseline for future deployments.
Finally, Simplified Debugging for AWS Lambda
Any developer who works with serverless functions knows that debugging can sometimes be a challenge. Sifting through CloudWatch logs to trace an issue across distributed components can be time-consuming and frustrating. A new enhancement aims to drastically improve this experience.
AWS has rolled out an advanced, native debugging capability directly for AWS Lambda. This new feature allows developers to perform step-through debugging, set breakpoints, and inspect the state of a function during its execution, just as you would with a local application.
Key Benefit: This is a game-changer for serverless development. It dramatically reduces the time it takes to troubleshoot and resolve bugs, leading to faster development cycles and more reliable applications. No more adding endless print statements to your code.
Actionable Tip: To get started, check your Lambda function’s configuration settings for the new debugging options. You can typically enable it through the AWS Toolkit for your favorite IDE, like VS Code, allowing for a seamless and intuitive debugging workflow.
Achieve Zero-Downtime Deployments with Native ECS Blue/Green Support
For teams running containerized applications on Amazon Elastic Container Service (ECS), ensuring safe and seamless deployments is paramount. While blue/green deployments have always been a best practice, setting them up often required custom scripting and complex pipeline configurations.
Now, AWS has simplified this process by introducing native support for blue/green deployments in ECS, fully integrated with AWS CodeDeploy. A blue/green strategy involves running two identical production environments—”blue” and “green.” You deploy the new version of your application to the idle environment (green) and, after testing, switch traffic over from the live environment (blue).
Key Benefits: This method provides zero-downtime deployments and offers an instant rollback capability. If any issues are detected in the new version, you can immediately redirect traffic back to the old environment, minimizing impact on your users.
Actionable Tip: If you’re using ECS, it’s time to review your current deployment scripts. You may be able to replace complex, custom-built logic with this streamlined, native solution, making your CI/CD pipelines simpler, more reliable, and easier to maintain.
Building Smarter AI with Amazon Bedrock AgentCore
Generative AI is evolving beyond simple text generation. The real power lies in creating autonomous agents that can reason, plan, and interact with other systems to complete complex tasks. To accelerate this, a foundational update has been released for Amazon Bedrock.
AgentCore for Amazon Bedrock is a significant enhancement to the Agents for Bedrock service. It provides a more robust and flexible framework for building sophisticated AI agents. AgentCore improves an agent’s ability to orchestrate tasks, make API calls to your internal and external services, and access data sources to provide accurate, context-aware responses.
Key Benefit: This update empowers developers to build more capable and reliable AI agents with less effort. It handles much of the complex orchestration logic, allowing you to focus on defining the agent’s unique skills and knowledge base.
Actionable Tip: Start by exploring the updated Bedrock documentation and try building a simple agent that connects to one of your existing APIs. This hands-on experience is the best way to understand how AgentCore can be leveraged to automate business processes or create powerful new user-facing features.
Staying Ahead in the Cloud
These updates represent more than just incremental improvements; they are strategic enhancements that address critical needs in security, development efficiency, operational excellence, and AI innovation. By understanding and adopting these new tools, you can not only improve your current applications but also position your organization to take advantage of the next wave of cloud technology.
