In a traditional scenario, if you want to develop an application, you need to have a server where your desired operating system and required software can be installed. While you are writing your code, you need to make sure that your server is up and running. During deployment, you need to add more servers to keep up with user demand and add scaling mechanisms such as Auto Scaling to manage the desired number of servers to fulfill users' requests. In this entire situation, a lot of effort goes into infrastructure management and maintenance, which has nothing to do with your business problem.

Serverless means there is no server to run your code, which frees you up from Auto Scaling and decoupling overheads while providing a low-cost model.
A public cloud, such as AWS, provides several...
