I haven’t had much time to write lately. Between consulting work and my master’s studies, spare time is scarce — which I think is understandable. That said, I really enjoy it, despite how tiring it can be. I’ve learned (and keep learning) a lot from each course, so I already have mixed feelings about finishing the program next year. Still, the...

This is article number 100. I started this blog around 2019—built it up in March or April, but didn’t start posting until May. I posted my welcome article on May 6th, followed the next day by the first post in my S.O.L.I.D series (which I only now realize I posted as D.S.O.L.I—completely out of order). I think I read somewhere that having a bl...

Quick announcement. Until recently, I’ve been adding and sharing the labs in the Cloud Experiments series using the blog’s main code samples repository. There’s a bunch of other interesting stuff there—like the Pandas labs and the code for the deep learning series—so it’s still worth checking out from time to time. In less than two weeks, I’ll...

I recently found a nice tool that may make your life easier when writing infrastructure as code using CDK. I Wanted Tests I noticed that the cdk init command creates a default test folder, and started reading about how to write effective tests for your IaC. It’s quite easy actually, and after you get the hang of it, it can be very entertainin...

I don’t have much experience with TypeScript—actually, I’d never touched the language until recently when I started writing Infrastructure as Code using CDK. Today I learned a useful trick that can help clean up sections of your stack by putting shared configuration in an object and then using the spread operator to merge those settings into the...

If you’ve been following this blog, you may have noticed that I consistently include two specific parameters when creating S3 buckets: const someBucket = new s3.Bucket(this, "someBucket", { // ... more bucket properties, sometimes none removalPolicy: cdk.RemovalPolicy.DESTROY, autoDeleteObjects: true, }); These parameters work together ...

I recently worked on a project that required creating and attaching an RDS Proxy to an already existing RDS instance running PostgreSQL. It seems easy enough, but I kept getting a validation error that took some time to resolve. What I Was Doing (This Doesn’t Work) My first attempt used the standard fromLookup function to reference an existing...

Lambda functions are typically executed in environments created from the default runtimes provided by AWS (such as python3.13 or ruby3.4). These runtimes come pre-loaded with many popular modules, like boto3 (the Python AWS SDK), so you often don’t need to install additional dependencies for routine tasks. However, you may eventually need a mo...
