Does Serverless Computing Offer the Benefits of Microservices?

Often this kind of question arises in the mind of who are new to the world of cloud computing. We have discussed some basic around serverless including What Problems are Solved by Serverless, Relationship Between Serverless Computing and Microservices, What Is a Serverless Microservice and so on. Serverless is an excellent environment to build a microservices architecture due to optimal virtualization of resources and for reusing APIs of the others. Combining serverless with microservice architecture several benefits resulting better scalability.

The biggest advantage of Serverless computing is that we do not need to deal with backend server management anymore. That factor brings plenty of benefits, like PaaS brings some benefits. Another good point of the serverless is automatic scaling. It eventually brings zero cost at idling. The cost will grow higher if load grows higher. This linear function actually was absent in traditional cloud computing service delivery models.

Zero machine maintenance means increased overall security, less steep learning curve and lesser burden. Instead of too many diverse types of DevOps and containerization tools, with serverless the developers can focus on the main business logic. Eventually, these backend factors bring the growth of the software business. It is also good for software clients. As a direct consequence of this progress, developers and software engineers can achieve full control of their software design, implementation, deployment, monitoring, bug-fixing, etc.

FaaS ensures a very granular approach based on individual Functions. Each function can be implemented via different languages. Serverless computing helps to develop and deploy state-less services, like with the other technologies which enable microservices. It is not exactly possible to compare microservices with serverless computing as they are really of a different breed. Microservices is one way to design software as loosely coupled services. Microservices broke down the traditional monolithic applications into loosely coupled services. Systems which has already adopted the microservices architecture are at a better position to move to serverless while maintaining the microservice architecture.
