Serverless Architecture: When and How to Use It

Serverless (FaaS and managed backends) lets you run code and services without managing servers. Here's a practical overview.

What Is Serverless?

You deploy functions or use managed APIs; the provider handles scaling, patching, and availability. You pay per execution or request.

When Serverless Works Well

• Event-driven workloads (webhooks, file processing, queues).
• APIs with variable or unpredictable traffic.
• Short-running, stateless tasks.

Considerations

Cold starts, execution time limits, and vendor lock-in can matter. For long-running or stateful workloads, containers or VMs might be better.

Getting Started

Start with a single function or a small API. Use infrastructure-as-code to keep environments consistent and repeatable.

Sohobcom offers serverless and container options so you can choose the right abstraction for each workload.
