AWS re-engineered Lambda VPC networking in 2019 with Hyperplane ENIs, eliminating the cold start penalty entirely.

Every tool call in an agentic loop replays the full conversation history.

Most developers treat Claude Code as stateless.

The AI agent part was easy.

A hands-on tutorial building a coding agent CLI with the AWS Strands SDK.

Claude Code's documentation tells you to use shell environment variables for Bedrock config.

Skills teach how.

Kiro's new open weight models run at 0.05x to 0.25x the cost of larger frontier models.

Lambda Durable Functions store your checkpoint data safely and securely, but do you really want all your system operators to see credit card numbers?

Using the Kiro IDE on Windows with Windows Subsystem for Linux (WSL) feels like a dark art.

That URL looks public, so surely that traffic is going across the public internet?

Dive deep into how Web Sockets really work and understand what they actually provide as a part of your architecture.

We all just copy MCP configs from READMEs and hope for the best. run-mcp lets you keep that simplicity while running servers in complete isolation.

Kick off those long-running tasks quickly and easily using an Event Driven solution leveraging AWS Web Sockets.

A Web Socket primer!

URL Shortener projects feel a little like the “Hello World” of programming.

The data you log is critical to understanding how your system is working, learn more about what you should log!

Logging sounds pretty simple.

Did you ever wonder how your logs get into Cloudwatch?

A lot goes on when your Lambda function emits a log entry.

Logging for Observability is always harder than it needs to be.

Have you ever wondered how to tell if your Serverless system is going wrong or have you ever seen what happens when Scalability boundaries clash?

Observability feels hard, but it doesn't have to be.

When you are building with AWS Lambda, you need to understand how it works in different situations.

Observability is a mindset.

Scalability boundaries are the number one enemy of Serverless.

Serverless thinking is not just about Lambda!

You need to retrain your brain and start to get into the Serverless mindset.

Before you get started, we need to clear up what Serverless means.

What's next for Serverless DNA?

Our mission statement, what we stand for and what we aim to achieve.

Often we like to jump in and get building straight away without learning everything we need to know.

We use Next.JS and react-markdown for rendering markdown content.

Rendering Markdown content with react-markdown is straightforward.

We ask ChatGPT all the hard questions, read on to see what it said.

We love to jump in and get building ASAP after we create an AWS account but, take a pause and make sure the credentials you use for your AWS CLI are secure!

We asked chatgpt "If I wanted to build a solution with AWS Serverless technology.
