Choosing between SQS, SNS, Kinesis, and EventBridge

AWS can overwhelm with the number of services. Especially if multiple services seem to do a very similar job. Let’s look at the cloud-native AWS messaging services – the SQS, SNS, Kinesis, and EventBridge. What are the differences and when to use which one?

I know my coworkers and teammates are reading this, and probably my boss as well. But let’s risk it.

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.

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.

Welcome to the first issue of Things I Found Interesting – an irregular series of links to, well, interesting content. Below are eleven articles and resources on various software-related topics, which I stumbled upon in the last several weeks.

Pin exact dependency versions

Buckle up, for some of you this may be controversial, but maybe for some others – obvious. This is how to prevent a problem causing your application to out of the sudden stop behaving correctly, or, even more funny, stop behaving correctly only on one developer’s computer. We can solve this with ~~one~~ two simple tricks.

Three ways to create Amazon Athena tables

Here I show three ways to create Amazon Athena tables. More importantly, I show when to use which one (and when don’t) depending on the case, with comparison and tips, and a sample data flow architecture implementation. Also, I have a short rant over redundant AWS Glue features. All in a single article. Enjoy.
