The application which was to be deployed on the environment included the following stack:

• NodeJS

• PHP

• PostgreSQL

• Nginx

The business goal was to develop a flawless and as stable as a possible environment with an advanced backup system.

The DevOps team has started the project from detailed planning and gathering metrics to follow. In the course of the planning, we faced multiple top-level challenges delivered from the client where the client wanted to either avoid some of the pains they have or minimize their impact.

As a result, all client’s business needs were solved with our technical solution. Now the existing system has:

• two separate servers for the back-end and for the balancer in the separate subnet;

• two separate servers for the front-end and for the balancer in the separate subnet;

• PostgreSQL for the front-end and for the back-end in the separate subnet.
