Let me tell you about a large bank and two data centers operated using VMware and the type of talent the bank is able to hire and retain. A move away from VMware is a 5-year project involving hiring, retraining, design mistakes, budget overruns, and a lot of grey hair. The year was 2012. 7 years later, one DC converted to OpenStack, the project is shelved and the majority of th OpenStack DC gets converted back to VMware due to “OpenStack disaster.”
