What is serverless computing?

The promise of serverless computing

What if you could spend all your time building and deploying great apps, and none of your time managing servers? Serverless computing lets you do just that because the infrastructure you need to run and scale your apps is managed for you. Focus your efforts on your business. Redirect resources from infrastructure management into innovating and bringing apps to market faster.

What is serverless computing?

Serverless computing is the abstraction of servers, infrastructure, and operating systems. When you build serverless apps you don’t need to provision and manage any servers, so you can take your mind off infrastructure concerns. Serverless computing is driven by the reaction to events and triggers happening in near-real-time—in the cloud. As a fully managed service, server management and capacity planning are invisible to the developer and billing is based just on resources consumed or the actual time your code is running.

Why build serverless applications?

Benefit from fully managed services

Spare your teams the burden of managing servers. By utilizing fully managed services, you focus on your business logic and avoid administrative tasks. With serverless architecture you simply deploy your code, and it runs with high availability.

Scale flexibly

Serverless compute scales from nothing to handle tens of thousands of concurrent functions almost instantly (within seconds), to match any workload, and without requiring scale configuration—it reacts to events and triggers in near-real time.

Only pay for resources you use

With serverless architecture, you only pay for the time your code is running. Serverless computing is event-driven, and resources are allocated as soon as they’re triggered by an event. You’re only charged for the time and resources it takes to execute your code—through sub-second billing.
