As I was trudging through access control issues in the last chapter, I found that there were scalability issues with the current implementation. This short chapter will recap the issues and fixes for the tooling for scalability, as well as how to test whether full horizontal scalability has been achieved. …

As of 30th April 2022, I’ve gotten CKA-certified!!! 🥳 🎉 Oops, not to say that this will be a self-congratulatory post (though I would be hard-pressed to admit that it kind of is). This is also not a post to teach you how to pass this exam, since there are…

In the last two chapters, we have been mostly occupied with the initial setup of EKS, along with initial monitoring tools for understanding our cluster better.

However, starting a project from scratch with Kubernetes, that’s something that I suspect most, including myself, have not yet experienced before. For me, this…

Let’s start with, Trust, and the world we live in Taking a look at the whole world, we can observe that it is run by different systems of “trust”. Our entire financial system is predicated on trust.

“Weiyuan, what tier-ed architecture are we on today? 2-tier or 3-tier?” — Le Boss Me — “😳” Earlier this week, I was caught, with my pants down — I was asked the above question and didn’t know how to answer it. To be completely honest, I have never heard about…
