Serverless is a cloud systems architecture that depends on third-party services also know as (BaaS) – Backend as a service or they run on temporary container also known as (FaaS) – Function as a Service. They don’t involve any servers, virtual machines, or containers to provision or manage.
Using serverless developers need not worry about the servers as they will give their respective function to the service provider who will run their function on demand or on an event basis.
Saves Time & Overhead Costs
Serverless computing is based on ‘pay as you use’ model ṭhat's what makes it more interesting. You will be charged for the time your function is running and the number of times it is triggered. In this way, you can save a lot of money.
Event-based Compute Experience
Companies always worry about their infrastructure costs and servers when their Functions call rate become very high. As serverless operates on an event-driven basis, developers no longer have to rely on ops to test their code.
No worries about the machinery
Infrastructure as a Service assures developers that they can stop worrying about how many machines are needed at any given point of time, especially during peak hours, whether the machines are optimized enough and are the security measures tight enough.
