I’m locking in for the next 90 days.
12 years of Linux, Datacenter , DevOps, SRE, Cloud & Architecture — I’m going back through all of it and refreshing everything from the ground up.
I’m going to share the whole journey here — notes, learnings, experiments, mistakes, and everything in between.
If you’re into infra, cloud, DevOps, SRE, or just love tech, keep an eye on this profile.
This is going to be one hell of a journey - That’s my promise.

Sure, with you on this journey. If you stumbled upon any networking concept do let me know. Post your learnings here and also the articles if you encounter any great one.

We were doing aggressive AWS cost optimisation in my company, Today I saw an AWS account in our org paying a noticeable amount just because S3 was configured with SSE-KMS even though there was no real compliance requirement for it.
In that case, SSE-S3 would have been enough.
Let me explain it with an example:
1B KMS requests/month
SSE-S3 → $0 additional encryption cost
SSE-KMS → ~$3,000/month additional KMS cost
SSE-KMS is great when you need tighter key control, auditing, or compliance.
Otherwise, don’t pay for complexity you don’t need.

These are the two different API gateway pattern where we need CDN features.
1. User → Edge-Optimized API Gateway → backend
2. User → Your CloudFront → Regional API Gateway → backend
Choose option 1, if you want simple integrated CDN layer with api gateway, but if you want to control entire CDN layer configurations then prefer option 2.

Good distinction. The key trade-off is simplicity and integration versus granular control over the CDN layer.

I built a cool little game — check it out. 😄

Play, climb the leaderboard, and if you make it into the Top 10, you can list your product, startup, or X profile.

Just woke up to find yet another issue with @msftClarity. I’ve already lost track of 8K+ users because of this mess, and now the “last 24 hours” stats are literally showing the exact same number as yesterday. At this point, I’m not even sure if I’m using an analytics tool or a random number generator. You guys should just decommission the product, the support team had one job, and somehow they managed to make the problem part of the product

Yesterday in a casual meeting one of the fresher was making fun of some old code because the logic wasn’t very optimised!!!!
Fair enough, improving old code is always good. But I think newer engineers sometimes don’t realise the pain of writing and debugging this stuff in the pre-AI days. where we used to refer official docs and stackoverflow discussions to stitch each piece together.
Today you can throw almost any code into an AI and it’ll suggest 10 better ways to write it. That doesn’t mean the original developer was bad or the code was sloppy.
Every piece of old code has some context behind it 🙂

Exactly, in the AI era, you can't tell who is developing genuinely with complete understanding and who is doing AI dev.

Good reminder that code should be judged in context, not just by today’s standards. Understanding why a decision was made can be just as important as finding a better implementation.

Peer review getting harder nowadays, due to AI agent code. ( we can use agent to do the review but some case I would prefer manual review)
Some terraform codebases now look like full-blown application code, layers of abstractions and complex logic just to save a few lines.
I’ll choose simplicity over complexity every time.

Once we start building something alone then office works get bored easily, it's like we can't drop it as it's the financial backbone but difficult to work on boring stuff 🫤
