What is serverless computing and when should I use it for Indian apps?
Serverless computing lets you run code without managing servers — you write functions, upload them, and pay only when they execute (per-invocation pricing). The cloud provider handles infrastructure, scaling, and maintenance. Major platforms: AWS Lambda (most popular), Google Cloud Functions, Cloudflare Workers (edge computing, lowest latency). Use serverless for: event-driven tasks (process image on upload, send welcome email on signup), scheduled jobs (daily report generation), API backends with unpredictable traffic spikes (Diwali sale surge), and webhooks (Razorpay payment confirmation processing). Do NOT use serverless for: long-running processes over 15 minutes, applications needing persistent connections (WebSockets), or workloads running 24/7 (a constantly-running app is cheaper on a Connect Quest VPS). India use case: Razorpay webhook handler as Lambda function processes payment confirmations reliably without running a server 24/7. For always-on applications, Connect Quest VPS at Rs 699/month is more cost-effective than serverless. Evaluate at connectquest.co.in.
