What is Serverless?
A cloud computing model where the provider manages server infrastructure automatically, letting developers deploy code without provisioning or managing servers, scaling automatically with demand.
Understanding the Details
Serverless doesn't mean no servers—it means you don't manage them. You write functions that execute in response to events: HTTP requests, database changes, scheduled triggers. The cloud provider handles provisioning, scaling, and infrastructure. You pay per execution rather than for always-on servers. This model enables rapid development without ops overhead and automatic scaling from zero to massive demand. Serverless works well for variable workloads, APIs, and event processing, though it introduces considerations around cold starts, execution limits, and vendor lock-in.
How It Works in Practice
API endpoints
Each API route runs as a serverless function, scaling automatically when traffic spikes and costing nothing when idle.
Webhook processing
Incoming webhooks trigger serverless functions that process events, enrich data, and update databases.
Scheduled jobs
Daily data sync runs as a scheduled serverless function, executing for 5 minutes then disappearing.
Why It Matters
Serverless lets small teams build scalable systems without infrastructure expertise. It reduces ops burden, enables pay-per-use economics, and allows focus on application logic rather than server management.
What People Often Get Wrong
Serverless is always cheaper. Actually, high-volume consistent workloads can be cheaper on traditional servers.
Serverless means no ops. Actually, you still need to handle observability, error handling, and deployment pipelines.
Serverless functions are slow. Actually, cold start issues are manageable with warming strategies and edge deployment.
How We Handle Serverless
We build serverless architectures for web applications, APIs, and data pipelines, using appropriate patterns for each use case and avoiding common pitfalls around cold starts and execution limits.
