Function-as-a-Service

Trust your cloud provider to fully manage your infrastructure automatically

And you can fully focus on the development

Function-as-a-Service, also known as FaaS, is a cloud computing approach that allows code to run without the complex infrastructure that comes with a microservice architecture.

Storing and executing code, as a rule, requires the creation and management of infrastructure, further in brackets (physical or virtual server), OS, components, services, and so on) FaaS is a special case of serverless (serverless) architecture.

A serverless architecture does not mean there are no physical servers, but it does mean that a third party, rather than the end user, is responsible for configuring, managing and maintaining them.

Responding to various events or triggers, a part of the code implemented through FaaS is executed automatically, regardless of other parts of the code. The client pays only for the time during which the program is executed (by the second).

A function is the smallest executable unit, typically time-limited by the service provider for maximum efficiency. This is the next step in “detailing” after microservices.

Focus on development

You do not need to think about the technology stack, consumed resources, administer servers and balance their load. The result is faster time to market for products or updates.

More simple code

Development without reference to the environment (stateless), and you can also write each function in any language suitable for the task

Interaction with other PaaS services

FaaS interacts with other PaaS services by running code through FaaS, you can work with DBaaS or K8aaS, i.e. without your own infrastructure, you get a fully-fledged application running in the cloud

Dynamic scaling

The provider makes your function available via an API and manages resource allocation. Functions are tied to events, not to resources, they are easily scalable this is the main characteristic of FaaS
