Serverless Architecture and Why you Need it

Serverless architecture and its associated technologies have been around for about five years now. In these five years, serverless architecture has gained significant traction as the go-to operational model for small and medium-sized businesses looking to build applications, with multiple benefits for your business as well as for your clients and users.

Function as a Service

First, let’s make one thing clear. “Serverless” does not mean the complete lack of a server. Running your application still requires the capabilities of software hosted on a piece of hardware. The application you are building is simply hosted by a third-party service provider, eliminating the need for server management by your developers.

The applications and software being built are event-triggered and run in stateless compute containers which are managed by third-party service providers. Amazon Web Services’ Lambda is a popular example of providing Function as a Service, where the applications built are run without the provisioning or management of servers by the organization building the application. You will only have to pay for the computing power used.

In terms of responsibilities at the front-end of the application, the developer is required to build the user interface and the client side capabilities. In the back end, he/she is required to build the server side logic. The FaaS providers, on the other hand, are required to provide hosting, scaling, optimization and modularity for the application built.

In FaaS, the developers simply have to upload their code on to the service and the service providers take care of provisioning resources and instantiating virtual machines. By providing developers with the opportunity to focus on the front end functionalities instead of the backend architecture, serverless architecture is making the job of developers much easier.
