When I started working with VMware ESX in the early 2000, I knew it was a very cool tech; and not only me, everyone knew there’s something special about it.
However, I haven’t fully grasped the full value of this technology right of the gate, at that point, I only saw “server consolidation” in front of me.
When vMotion came out, and we realized that physics has changed for our servers, we were no longer tied to the hardware the Server was running on. That hardware abstraction allowed us to do things we couldn’t do before. like fixing hardware issues or patch it with no downtime, scale much better and faster by deploying VMs when we need them and monitor the health of the infrastructure much better, even self heal. A new exciting world of agility we never saw before was opened.
