Is ‘VM Stall’ the Next Big Virtualization Challenge?

Is ‘VM Stall’ the Next Big Virtualization Challenge?

There appears to be a challenger to ‘VM sprawl’ as the scourge of virtualization success - a problem I call ‘VM stall’. We know about ‘VM sprawl’ – because new virtual machines are so easy to deploy, organizations can end up with more VMs that they can handle, or even use. This has the potential to cause severe problems to availability, performance, compliance, costs, security, and more. However, I am seeing more and more evidence of this new phenomenon I think of as ‘VM stall’ – the tendency for virtualization deployments to stall once the ‘low-hanging fruit’ has been converted (typically around 20-30% of servers). I think it happens more or less like this...

Not every IT organization needs a fully self-service interface, and many smaller organizations see no value in usage metering. They simply want to deliver services faster. For them, a 70% private cloud is absolutely good enough … it all comes down to business requirements, return on investment, and future strategy. How far you go is your decision. via Driving for Imperfection With Your Private Cloud.…

You Cannot Separate Security and Systems Management

You Cannot Separate Security and Systems Management

A few days ago I was pleased to brief again with Reflex Systems. Apart from the fact that they are doing some very cool things with virtualization management, their approach struck me as, if not unique, at least pleasantly rare. Good for them! What I liked most was that they are trying to break down the barriers between systems and security management.
