🤔 DevOps & SRE Kya Hai?
DevOps + SRE (Site Reliability Engineering) + Platform Engineering — Indian IT industry mein last 5-7 saal mein sabse fast-growing tracks bane hain. DevOps initially scripting + deployment automation tha; ab Cloud (AWS/Azure/GCP) + Kubernetes + Terraform/Pulumi (IaC — Infrastructure as Code) + observability (Datadog, Grafana, Prometheus, New Relic) + CI/CD (Jenkins, GitHub Actions, ArgoCD) + security (DevSecOps) — comprehensive role hai. SRE — Google ne pioneer kiya, ab Microsoft, Meta, Amazon, Adobe, Walmart Labs sab adopt karte hain. SRE focus production reliability + SLO/SLI + error budget + on-call rotation + incident management + chaos engineering. Platform Engineering — internal developer platform build karta hai (Backstage-like portals, self-service infra). India mein DevOps / SRE / Platform roles kaafi premium pay karte hain — services side ₹10-25 LPA mid-level, product ₹25-50 LPA, FAANG ₹50 LPA - 1.5 Cr. Iss chat mein hum DevOps / SRE / Platform engineers ki real challenges discuss karte hain — on-call rotation ki sleep-disrupting reality, Kubernetes deep dive ka 6-12 month curve, Terraform multi-cloud setup, Prometheus + Grafana observability stack, incident management aur post-mortem culture, security shifting (SAST, DAST, secret scanning), aur 'paged at 3 AM' burnout ki honest baat. Karier path — Junior DevOps → DevOps Engineer → Senior DevOps / SRE → Lead SRE → Platform Engineering Manager / Principal SRE. SDE-to-SRE switch popular hai (similar pay, less product-feature pressure). QA-to-DevOps switch bhi possible — automation + scripting overlap hai.
