Just updated my 11 years old EX442 Red Hat Certified Specialist in Linux Performance Tuning certification. First I did it on RHEL 5 in 2009 when I finished my RHCA certification. Now updated it on RHEL 8. It is still one of the hardest exams I ever passed.

10 years RHCA

Ten years ago, January 2009, in Stockholm I passed the last of five required hands-on exams and got Red Hat Certified Architect (RHCA) certification. Those days it was about 300 RHCA worldwide and I was the second for CIS/Russia. As you have to pass exam before teach corresponding course, we could bring RHCA-level courses to Russia at Инвента training center after that. Looking back for the last 10 years I still think that this certification is valuable and the knowledge itself is relevant for my daily job.
