Kubernetes to RDS: secure connections via IAM roles without passwords

Databases are a cornerstone of any meaningful business application. Or not meaningful. Or not even business. They keep things consistent. Yes, that’s the one.

For decades, we’ve been using usernames and passwords to connect to databases inside applications.

And in this article, I’m going to show you the entire process of configuring a database connection using AWS native tools -- IAM roles and policies.

EKS Auto Mode custom NodeClasses and NodePools

Hello, dear reader! It's been a while since our last one-way communication. Mostly because the last couple of months have been taxing on me. Searching for a new job is not an easy task these days. Also, there’s been a new Warhammer box, which I just couldn’t resist.

Everything* as code

Hello, dear visitor. Seeing you here today means you're likely a developer, engineer, coder, or some combination of these -- and that you're familiar with the term "code". For several decades engineers all over the world were writing code. This code, first and foremost, was meant to solve problems. And today I would like to tell you about solving even more problems with the power of code. I will show you why and how we should use code for more and more scenarios across our professional and personal lives.

A Beginner's Guide to AWS S3 Block Public Access

S3 is an incredibly useful service for storing and sharing a vast variety of files. Due to its ability to store files in a bucket accessible to a broad audience, it is even possible to host a static website. The first "S" in the acronym S3 stands for "Simple." But is it actually so simple when it comes to public access?
