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.

Открыт предзаказ на четвертое издание моей книги по OpenStack. В 4-е издание добавлен материал по работе с сетью, настройками производительности и отказоустойчивости. В связи с переходом на сервис Gnocchi переработана глава, посвященная сервису телеметрии.

Ниже приведены некоторые изменения четвертого издания, по сравнению с третьим:

• Обновлены главы, посвященные основным сервисам OpenStack, в соответствии с изменениями на начало 2018 года (версия Queens).
• Добавлен материал в главах, посвященных работе с сетью, настройками производительности и отказоустойчивости.
• Переработана глава, посвященная сервису телеметрии, в связи с переходом на сервис Gnocchi.
• Примеры большинства команд обновлены с использованием клиента командной строки openstack.

I have received the results of EX310 Red Hat Certified Engineer in Red Hat OpenStack just now. I have upgraded my Red Hat Certified Architect Level to XI :) Exam was all about Networking & Foundations of NFV in OpenStack. Since my job role focus will shift from NVFi to another area, this exam was a good conclusion for the last two years of working with OpenStack :)

I have created diagram which shows how Director deployed services in RHOSP 10. That is something like summary for “UNDERSTANDING RED HAT OPENSTACK PLATFORM HIGH AVAILABILITY ” guide. If you learning RHOSP it would be useful.

I have received the results for EX220 Red Hat Certified Specialist in Hybrid Cloud Management today. Now I have Red Hat Certified Architect Level X.
