Tired of bloated Docker images? Distroless might be your answer. No shell, no package manager — just what your app needs to run. 🔒 More secure ⚡️ Smaller & faster 📦 Great for prod I broke it down in a new post: 👉 medium.com/@rajat41997/di… #Docker #DevOps #Containers

I used to avoid System Design. Too complex. Too many buzzwords. “Not for me.” No idea how to design at scale. Then came the wake-up call. Here’s how I actually learned System Design 🧵 ✅ Accepted I didn’t get it, and that was okay 🧩 Broke it down: DNS, DBs, Queues, Scaling 👀

The moment I realized I finally "got" DevOps? When I stopped thinking in tools and started thinking in systems. It wasn’t about Terraform, Ansible, or Jenkins. It was about: – Reducing manual toil – Building reliable infra – Empowering Devs – Automating trust That’s when it

After spending more than half a decade in corporate, I’ve finally learned to decode the language. Here’s your updated 2025 translation guide 🧵: "I'll sync with the team" = That's a no, but politely. "It’s on the backlog" = Maybe… in another universe. "Strategic priority" =

No one jumps from 3 LPA to 50 LPA overnight. It’s usually 3 to 8, then 20, and eventually 50. It’s a journey, and in most cases, switching roles is the only constant. Speaking from personal experience, I’m still on the path, still learning, but this is the reality.

Here are the DevOps tools I use every single week and exactly why I keep reaching for them: 🧵 1. Terraform — infra as code default 2. Vault — secret mgmt done right 3. Docker — consistent local builds 4. Nomad — lightweight scheduling 5. Consul — Service Discovery 6. GitHub
