What is hyperconverging?

Hyperconverging is the latest hype: do things more efficiently with the resources that you have by cramming as many virtual machines on the same hypervisor. In theory this should allow you to mix and match various workloads to make the optimum use of your hypervisor (e.g. all cores used 100% of the time, overbooking your memory up to 200%, moving virtuals around like there is no tomorrow). Any cloud provider is hyperconverging their infrastructure and this has pros and cons. The pro is that it’s much cheaper to run many different workloads while the con clearly is when you encounter noisy neighbors. As Jeremy Cole said: “We are utilizing our virtual machines to the max. If you are on the same hypervisor as us, sorry!”

Apart from cloud providers, you could hyperconverge your infrastructure yourself. There are a few hardware/software vendors out there that will help you with that and at one of my …
