Creating and managing all available resources offered by major cloud providers exclusively in free-tier plans. Using Terraform to create and manage all the resources in a simplified and centralized manner.
Every major cloud provider offers a free tier that allows for some kind of resource free of charge, still, learning every cloud and managing these resources can prove burdensome to most.
The goal is to automate the management of these resources using Terraform as the centralizing tool. It also aims to provide resources for learning and improve your skills as a SRE/DevOps Engineer and as a Terraform user, even if you're developer that never touched cloud infrastructure, nowadays there's great value in learning these tools.
