What is serverless?
Serverless computing—popularized by platforms like AWS Lambda, Azure Functions and Google Cloud Functions—allows developers to run code without provisioning or managing servers. You pay only for the compute time used, while the provider handles scaling and maintenance.
Benefits of serverless
- Cost savings: Billing is based on execution time and resources consumed, which reduces costs for variable workloads.
- Automatic scaling: Functions scale instantly to handle spikes in traffic and scale down to zero when idle.
- Faster development: Developers focus on code, not infrastructure; this accelerates innovation and reduces time to market.
Considerations and best practices
- Cold start latency: Initial invocation of a function may incur delay; optimize by keeping functions warm or bundling dependencies efficiently.
- Stateless design: Functions should be stateless; state must be stored in external services (databases, caches or queues).
- Vendor lock‑in: Functions may rely on provider‑specific features; design with portability in mind.
