About RCW IT Training
RCW IT Training is a free, browser-based practice ground for people who run — or want to run — enterprise infrastructure: Linux and RHEL, Microsoft Intune and Azure, AWS and GCP, VMware, storage, backup and networking. Everything on the site is public, needs no account, and is written by one person who still does this work every day.

I design and operate infrastructure for large organisations — VMware and Linux estates, Active Directory and Entra ID, Microsoft Intune device management, backup and storage platforms, and workloads on AWS, Azure and GCP. RCW IT Training started as the practice environment I wished I had when I was preparing for my first certifications, and grew into the labs, simulators and troubleshooting notes published here.
- Focus: VMware and Linux estates, Active Directory and Entra ID, Microsoft Intune device management, backup and storage platforms, and workloads on AWS, Azure and GCP.
- Teaching: 14 RHEL 10 video lessons on YouTube, plus the labs, simulators and practice tasks published on this site.
What is on the site
- Hands-on labs — a simulated terminal with objectives that are checked as you type: Linux administration, Docker, Kubernetes, Ansible, Terraform, AWS/Azure/GCP CLI, databases and networking. Each lab page now opens with a written study guide so you can learn the concepts before, or instead of, running the lab.
- Certification practice — timed exam simulators for Microsoft Intune MD-102, Cisco CCNA 200-301, VMware Cloud Foundation and Citrix CCE-V, and a 62-task RHCSA series mapped to the published EX200 skill areas.
- Troubleshooting guides — long-form write-ups of production problems I have actually been paged for: AD replication, VMware datastores and PSODs, Intune enrolment, Veeam and Commvault jobs, Kubernetes workload failures, storage path loss and more.
- Incident-response desk and challenges — realistic tickets for freshers and L1 analysts, and scored challenges for experienced engineers.
How the content is made — and what it is not
Every lab and guide begins with a real scenario from production work or from a certification objective. I build and test it in a lab environment (RHEL 10, vSphere, an Intune tenant, cloud sandboxes), write it up, and publish it here. Where I use AI tools, it is for proof-reading and formatting; the technical content, command sequences and the mistakes described come from operating these systems. If a page reads like a vendor manual, that is a bug — please tell me.
The site is not affiliated with, endorsed by or sponsored by Red Hat, Microsoft, VMware/Broadcom, Cisco, Citrix, Amazon, Google or any other vendor named here. Practice questions are original and are not exam dumps; RHCSA tasks are original exercises aligned to public objectives, not exam content. All product names and trademarks belong to their owners.
Corrections and update policy
- Every article shows a published date and, when changed, an updated date.
- Guides are re-checked when a product version changes the behaviour described (for example, RHEL point releases and Intune service updates).
- Reported errors are fixed within a week and acknowledged on the page with credit to the reporter, unless they prefer otherwise.
