Unlike cloud computing where clients run applications on automated platforms and manage their own infrastructure, serverless computing architecture (middleware) allows payment for the service only when you need it.
While you pay for the resources you need for executing your codes, it does not mean that servers are no longer in use. This method provides developers with auto-scaled backend services for any bandwidth of resources they can afford.
Serverless computing has made the building of web applications easy. Developers can focus on coding and do not have to waste time and money managing their data centers but only pay for the computing services. With a modular architecture, developers can build efficient and reliable codes into a scalable registry within the database and storage services provided by serverless providers. Some of the backend services developers can tap into include function as a service that allows code development on the platform edge.
Some benefits of serverless computing are:
- It is economical-with server allocation, pay for the space and the infrastructure even if it is lying idle, while serverless computing is cheap and efficient.
- It is a simplified & scalable technology -service providers provide coding environments integrated with policies and scaling options paid as a service.
- A simple backend application – function as a service module allows developers to develop small pieces of code that solve a specific task.
- Faster execution – the architecture of serverless platforms has code debugging capabilities that allow quick release of well-tested products into the market.
Even though developers enjoy these simplified features of serverless computing, its main drawback is the inability to auto-start functions that have developed a cold start. It is a function in an idle state because of the system shutdown and needs manual spinning to process an application. These are the standards what and why of server computing architecture.
