How to use the Linux and DevOps hub

Use this hub when you want operational practice: commands, clusters, infrastructure, cloud services, and architecture decisions that show up in platform roles.

Start with LFCS when Linux fundamentals are the weak point.
Use CKA and Terraform for Kubernetes and infrastructure-as-code practice.
Add AZ-104, AZ-305, SAA-C03, or AWS Cloud Practitioner when cloud operations and architecture are part of the role.
