I’ve been thinking about this topic a lot lately when bringing EventBridge’s EventBus into some applications. On the current projects I’m working on with existing code, I’ve said 100 times, if EventBridge existed when I started them, I wouldn’t have so much SNS->SQS based code lying around. But such is life when working in evolving tech. Enter the EventBus Mesh

Subscribe SNS to EventBridge Pipes
Legacy Serverless to New Serverless
I’ve been thinking and working hard on how I can start to introduce EventBridge and Pipes into some of my existing applications. Unfortunately, I have SNS in front of a lot of my service code and you can’t natively subscribe SNS to EventBridge Pipes. So I’ve started pondering this idea of how to integrate Legacy Serverless Applications into an ecosystem as new features are developed with more modern Serverless concepts. What I really want is a way to connect SNS to EventBridge Pipes.

Canary Deployment for AWS Lambda
In life, when working on anything, small and iterative changes give us the best opportunity for feedback and learning. And it’s through that feedback and failure even that we get better. The same thing can be applied to building software. Small, iterative and independent deploys help us as builders understand if we’ve built the right thing and architected it correctly to handle the conditions asked of it. A technique called Canary Deployment is a popular model and the article below will demonstrate how to perform Canary Deployment for AWS Lambda
However, when deploying more frequently, we also need to do it safely. Shipping unfinished or potentially risky changes can have a big impact on our user base. No one wants to be in the middle of using your software only to be interrupted by a bad change. While we can’t be perfect in our ability to predict the impact or blast radius of a change, we can make it so that if the deploy shows signs of not being good, we can roll that change back without the need for human intervention.

BatchGetItem with Golang
I haven’t had to use the Batch API a great deal over the past few years. When thinking more on it, it’s not that I have anything against the API, it is just that I never had a reason to work with it. However, over the past couple of months I saw that I’d used it twice in a project and with good success. My Golang and DynamoDB content has been doing well so I figured there might be some appetite for this one. And with all that said, I wrote this article highlighting how to use DynamoDB’s BatchGetItem with Golang.
Common AWS CLI commands and explanations
I tend to lose track of some of the commands or things I run often and by the time I think to script or alias something, I’ve long sense forgotten it. Then I end up running history | grep -i <some phrase> hoping that it’s in my history. The point of this article is just to document and capture some the common AWS CLI commands that I use pretty often.
