Rate limiting is the first thing teams reach for against bot attacks. But attackers have adapted. distributed bots using residential proxies can spread requests across 200 real IPs, each staying under your threshold. Your logs show nothing unusual. ๐งต

That's exactly what happened to us. Rate limiting didn't catch it, as every request looked legitimate. By the time the aggregate told the story, our email sender reputation was already taking damage.

The fix was using AWS WAF CAPTCHA and Cloudflare Turnstile. I wrote about how we diagnosed it, why the obvious defences failed, and how we solved it.
If you're running any public endpoint that triggers an email, this is worth a read: poly4.hashnode.dev/why-rate-โฆ

Just passed the AWS Certified DevOps Engineer โ Professional exam!
Definitely a tough one; long, complex questions that really test your real-world AWS experience.
On to the next one ๐

Many teams start with S3 CloudFront, then later move marketing pages or blogs to Webflow.
Making both work on the same domain isnโt very straightforward.
I wrote about how to do it cleanly using CloudFront path-based routing:poly4.hashnode.dev/webflow-cโฆ

Engineers, build this habit; type out URLs of important apps (like your cloud console or NPM) instead of clicking links from emails.

Over the past few years, Iโve had the chance to work on multiple DevOps projects.
I reflect on that journey and write an article highlighting some of the most interesting of them and the lessons learnt.

๐I raise you DevOps
one time after sprint demo, designer was praising FE for pixel perfect work, frontend thanking BE for amazing api doc, BE praising FE and designer say it was nice working with them. I was like guys "I'll put off the prod env" as nobody remember infra ๐

I'm so jealous of designers. Their work speaks for them, no need for too much shalaye.
Backend dev? Lol.

I definitely love getting hands dirty with bare metal for sure but there are many usecases where I will choose cloud over bare metal. coz it's not about what tinkers me, it's about what's good for the product
14 Jul 2025
Every good Devops persons prefers bare metal to cloud. Cloud is usually preferred by the management team. Devops people enjoy tinkering, and bare metal gives them that joy.

If there's anything I miss in frontend, it's how easy it is to show your work and get accolades for it. Show a few UIs and everybody is clapping. But for DevOps, you go just dey explain explain ๐, shey na terminal I wan dey show stakeholders

all true until the googling part ๐

A true DevOps engineer doesnโt fear the terminal. They live in it. They know their shell, understand ps aux output, and fix things without googling every command.

Over the past 2 years, Iโve built transcription and subtitle support across 3 video learning platforms.
So, I wrote a guide on building a reusable subtitle service with AWS Transcribe.
