AEM: Deploying replication agents as code

Include your replication agents in your git repository

Use case

Let's imagine you want to install AEM with a pretty standard, simple topology. You may have 4 environments (local, dev, uat, prod) and each environments consists of one author replicating to two publishers.

That means you have 8 replication agents to set up, 12 if you add a dispatcher, 20 if you want reverse-replication, etc.

Configuring these replication agents can start to become a bit of a chore, especially if you are using custom replication and transport (receiver) users. You should btw, it's in the security checklist.

Data and operators

Writing a program is a lot like writing in English, there are certain rules to follow.

To describe what something is we use data. For example:

A number
True or false (ie: a boolean)
Some texxt (ie: a string)

Q1. What is the output of this program?

public class Test {
    public static void main(String[] args) {
        int n = 10;
        int next = 0;
        int nextNext = 1;
        for (int i = 1; i < n; i++) {
 nextNext = next + nextNext;
