6 Common Pitfalls of AWS Lambda with Kinesis Trigger

The simplicity of setting up a Kinesis trigger for a Lambda function may be deceptive. There are pitfalls that can cause problems we will spot only later, in the production environment. I learned about some of them the hard way, so let’s say I speak from the experience.

Headless CMS with Gatsby on AWS for $0.00 per month

Can you have a website with a CMS on AWS and not pay just for its existence? I looked at Amazon Lightsail, headless WordPress, and Webiny CMS but found none of those suitable. So I choose Prismic – a SaaS headless CMS, and Gatsby to create the site. Yes, I needed to make a pipeline to build my website after content changes. But when I did it, I got a website with CMS hosted at no cost.

AWS Lambda performance optimization

There are two reasons to optimize AWS Lambda functions performance. First is money – you pay for the Lambda execution duration. The quicker you do the job, the less you pay. The second is latency – the quicker you do the job, the shorter your client waits for the result. It’s a known fact that the decrease of latency improves sales, user engagement, and client satisfaction – so we could argue it’s also the money, in the end.

AWS JavaScript SDK v3 – usage, problems, testing

The new version of AWS SDK for JavaScript / TypeScript / Node.js came with a few significant improvements. But does “General Availability” mean “ready for the production”? How to use it? And how to unit test our code using it? Let’s take a look at it.

AWS Lambda logging best practices

Logging in AWS Lambda functions is simple. You just print the message, and it’s sent to the CloudWatch Logs. And everything is fine until you get a surprisingly big bill for the CloudWatch usage, or you need to actually debug some live system. Here are my tips for logging in AWS Lambda, based on my experience with real-live, big-scale functions running on production.
