Goals

Setup the extra infrastructure tools and become the devops master.

Load balancing

Redundancy

In this section our goal will be to have a redundant backend. Instead of having a single backend application let’s have 2 (Why not more? Do not forget that your server does not have unlimited resources).

Setup 2 backends instances: backend-1/backend-2 or backend-blue/backend green (my personal favorite).

Actual load balancing

Set up your reverse proxy to do some actual load-balancing between your 2 backends using: Mod proxy balancer.

Start by setting up your load balancing on your dev environment, once you are satisfied with the behavior deploy it to your production.

Tip

Ask yourself: why can we that easily load balance between our backends? Heard of sticky sessions or stateless apps?
