In active mode, the server initiates the data connection with the client after the client has established a connection on the command channel. In passive mode it is the other way round, the client initiates the data connection with the server.

Servlets are API which is simple and provides capabilities to write server side components. Web Service uses ServletContainer class which is again a Servlet class, which handles the request in clean and structured way. The REST stands for REpresentational STateless Protocol. Here the request won't store any data.

For RDS you have to choose what type of EC2 instance to run it on. So you are actually required to think about what virtual server you want underneath and you are also billed for those instances. With serverless you don't make that choice. ... A usual database needs a server where it is running on.
