End of September 2021, AWS announced Graviton 2 powered Lambda Functions. The announcement post says “All Lambda runtimes built on top of Amazon Linux 2, including the custom runtime, are supported on Arm…”. Not all languages out of the box, for using GO as fast language on a fast Graviton processor, you have to use Docker based deployment. Here I show you a simple - CDK powered way to do that.
CDK Lambda Deployment takes about a minute - how about sub second Function Code Deployment? Creation of Lambda infrastructure with the CDK is really powerful. Updating the Function code is really slow. Here is a fix for that to get to a sub-second Lambda
Detect the crack in the window (or the lambda library) before it breaks: As we have seen during the last month, also well known libraries like log4j can have previously unknown vulnerabilities. Therefore scanning your Lambda application before deploying i
In this blog, I take you along on my journey to build my first Golang-based Lambda function. Inspired by surprise on my RDS bill, I built a Lambda function in Go to periodically stop running databases with a specific tag. Come, learn and debug with me!
In hybrid architectures, serverless functions work together with container solutions. Lambda logs have to be translated when you don`t choose CloudWatch Logs. The old way of doing this is through subscription filters using additional Lambda functions for
CDK is great for serverless architectures. But the deploy times even for small lambda functions is to slow. Here is a little trick which can speed up things a lot. A small caveat: It is cheating.
