Serverless computing, or functions as a service (FaaS), abstracts where a particular component is running — or how overall resource capacity needs are satisfied — and is largely invisible to the application end-user, the application itself, and its developer. When applied properly, this approach can reduce IT operational costs, enable faster deployment of services, and improve performance for end-users.
Embarking upon a serverless path requires a cohesive strategy from the start. These key elements will help an organization succeed in this regard:
- Decompose the application into stateless, single-purpose functions. Stateless functions are infinitely scalable and easy to test.
- Decouple back-end logic from front-end applications. Building core business logic into the back end allows the front end to focus exclusively on interaction. This has security advantages as well.
- Incorporate security at every layer. Good fences make good neighbors. Ensure that each and every layer is doing input validation, authentication/authorization verification, etc.
- Establish clear visibility into every layer. Serverless doesn’t mean “magic.” Each layer must still be actively monitored.
