Many people may wonder if PowerHA clusters still make sense in today’s IT world, considering the solution was developed and operated when servers were large bare-metal machines without any virtualization or containerization. Of course, in an ideal world, everything would be cloud-based, and blowing up half the globe wouldn’t cause any service unavailability. However, in the imperfect world, the life of infrastructure and metal servers in our own Data Centers is fought for by brave administrators, and large systems that function for our daily convenience (including banking, telecommunications services, etc.) are often extremely difficult or unprofitable to rewrite into something more flexible.
