Load Balancer vs. Reverse Proxy? 🧭 🔹 Load Balancer: Distributes traffic across servers. 🔹 Reverse Proxy: Sits in front, handles routing, caching, SSL. Both = smarter traffic control! 🚦 #DevOps Stuff's 🧑‍💻

Rolling Updates in Kubernetes? 🚀 🔹 Update Pods gradually, not all at once. 🔹 Keep service available during deployment. 🔹 Safer, smoother rollouts. Always roll, never crash! ⚙️ #DevOps Stuff's 🧑‍💻

Zero Downtime Database Migrations? 🛢️ 🔹 Use expand and contract strategy. 🔹 Add new columns first ➔ Deploy app changes ➔ Remove old fields later. 🔹 Never break compatibility mid-deploy! Database changes are deployments too! Treat them carefully. 💣 #DevOps Stuff's 🧑‍💻

Chaos Engineering? 🔥 🔹 Break things on purpose to test system resilience. 🔹 Discover weaknesses before real outages. 🔹 Netflix pioneered it with Chaos Monkey. Better to fail safely than crash blindly! 🚨 #DevOps Stuff's 🧑‍💻

Monitoring vs. Observability? 📈🔍 🔹 Monitoring: Watch known problems. 🔹 Observability: Discover unknown problems. Logs, Metrics, Traces = your superpowers! 🦸‍♂️ #DevOps Stuff's 🧑‍💻

Why should you use Kubernetes Namespaces? 🏷️ 🔹 Logical separation of resources (apps, teams, stages). 🔹 Better RBAC (Role-Based Access Control) per namespace. 🔹 Limit blast radius: a bad deployment in one namespace won’t crash others! Namespaces=Natural multi-tenancy for K8s🚀

What is SRE Error Budget? 🧮 🔹 Error Budget = 100% - SLO. 🔹 Example: 99.9% uptime goal ➔ 0.1% allowed failure. 🔹 Teams can innovate/fail as long as budget isn't exhausted. Error Budgets = Balance between stability and speed! ⚖️ #DevOps Stuff's 🧑‍💻

Think Linux permissions are just about rwx? 🤔 True system control goes deeper. A simple way to set a memory limit for a process in the current shell: $ ulimit -v 512000 This limits virtual memory to ~500MB. It's resource permission in action! #Linux #DevOps #SRE
