Ballerina has been built for integration purposes, having the native ability for working with JSON and XML messages, and easy build for APIs using HTTP, REST, and Swagger to define and implement it.
We can make two different types of applications in this programming language--network services and main functions. On the one hand, we have the network services that keep waiting once launched for incoming requests, until the process is stopped. On the other hand, the main function does a specific action when it is launched and then finished until the next execution.
