What is serverless computing?

Serverless computing is a method of providing backend services on an as-used basis, eliminating the need to manage server infrastructure.

What is serverless computing?

Serverless computing is a cloud execution model where the cloud provider dynamically manages the allocation and provisioning of servers. Despite the name, servers are still involved — developers simply do not need to manage them. The cloud provider handles all infrastructure concerns including scaling, patching, and capacity planning.

How does serverless differ from other cloud models?

In traditional cloud computing, developers provision and manage virtual servers. With serverless, the provider abstracts away all infrastructure. Code runs in stateless compute containers that are event-triggered, ephemeral, and fully managed by the provider.

Benefits of serverless

  • No server management: Zero infrastructure administration
  • Auto-scaling: Automatically scales with demand
  • Pay-per-use: Only pay for actual compute time consumed
  • Reduced time to market: Focus on code, not infrastructure

Serverless use cases

Serverless excels at event-driven workloads, API backends, data processing, scheduled tasks, and webhook handling.
