Serverless Computing

Serverless computing is a method of providing backend services on an as-used basis. A serverless provider allows users to write and deploy code without the hassle of worrying about the underlying infrastructure. A company that gets backend services from a serverless vendor is charged based on their computation and do not have to reserve and pay for a fixed amount of bandwidth or number of servers, as the service is auto-scaling.

Advantages of Serverless Computing

• Lower costs - Serverless computing is generally very cost-effective, as traditional cloud providers of backend services often result in the user paying for unused space or idle CPU time.
• Simplified scalability - Developers using serverless architecture don’t have to worry about policies to scale up their code. The serverless vendor handles all of the scaling on demand.
• Simplified backend code -With FaaS, developers can create simple functions that independently perform a single purpose, like making an API call.
• Quicker turnaround -Serverless architecture can significantly cut time to market. Instead of needing a complicated deploy process to roll out bug fixes and new features, developers can add and modify code on a piecemeal basis.

Backend-as-a-service (BaaS):- is a service model where a cloud provider offers backend services such as data storage, so that developers can focus on writing front-end code. But while serverless applications are event-driven and run on the edge, BaaS applications may not meet either of these requirements.

Platform-as-a-service (PaaS):- is a model where developers essentially rent all the necessary tools to develop and deploy applications from a cloud provider, including things like operating systems and middleware.
