Serverless is a natural evolution or extension to microservices where each function is understood as mini-service. A single chunk of code or ‘function’ is executed any time a distinct event occurs. The function ‘wakes up’ takes some amount of time to execute and consume the server’s resources, including memory before getting vanished after completing the task.
