Things That Lurk in the Background

Now that the preliminary infrastructure for our GitLab POC is in place, we are ready to build up the key components of the POC back-end services. In this chapter, we will cover the creation of both the PostgreSQL database and the Redis database required for GitLab. We will also tackle the spinning up of bastion servers in our public subnets that we will need later to access servers in our private subnets.
