Part 4 of a 5-part series based on my more than a decade of virtualization experience with large enterprises and service providers, and my time running strategic planning for one of the largest 2 virtualization vendors, this blog series covers 10 types of situations when you should consider not virtualizing some of your applications.
Reason 7: When you don’t have a way to manage encryption keys
Encryption keys are easy to manage on physical servers. When secure workloads move around because of virtualization, encryption key management designed for physical servers won’t work. The obvious...

Reason 5: When you work for a cheapskate
Sorry, like an worthwhile IT project, virtualization requires a budget. If you don’t have a way to pay for the project, don’t start it. Halfway implemented virtualization without adequate tools is worse than whatever you...

I. When it just won’t work very well
There are some apps that just don’t work well on virtualization for a variety of reasons. VM vendors are getting better are supporting these special cases, and some new technologies like I/O virtualization are coming along...

Perhaps bubonic plague is uncommon, but influenza or cold germs are easily transmitted in the public domain. What degree of assurance do you have that when you check into your hotel room, that it is safe and sanitized? The hotel employs a cleaning staff and adheres to standards of cleanliness and hygiene to ensure your room is clean. However, door knobs, elevator buttons etc handled by the other guests all day, are an avenue of transport for infection. These are some of the risks we take in daily public life – our own immune systems and personal hygiene help to ward off illness and infection.
When...

At cloudexpo yesterday, I chatted with Allan Allison, after his session on cloud security. Subsequently, I read his blog post which advises organizations considering the cloud, how they can leverage compliance factors when selecting a cloud provider (for example if the customer’s data is subject to HIPAA, HITECH, PCI and similar regulations).
When you migrate to the cloud, compliance factors are one item to consider, security is another.
If your applications and data are hosted on physical servers in your datacenter, under your control, security can be achieved with in-line network appliances...

Virtualization and private cloud have enabled server consolidation, created more flexible environments, and saved companies a ton of money.
Virtualization is a good thing.
But it’s not always a panacea. Trend Micro’s recent survey of 1200 companies with more than 500 employees showed that 59% had server virtualization in production or pilot. But based on my more than a decade of virtualization experience with large enterprises and service providers, and my time running strategic planning for one of the largest 2 virtualization vendors, this blog series covers 10 types of situations when...

Check out this new release from Greylock Partners, which calls Pure Storage “one of the most exciting enterprise companies in the Greylock Portfolio.” Pure Storage makes a flash based storage array. Greylock is a solid VC – I’ve pitched them on startup ideas a few times over the years.
I’m the first to admit that storage arrays might be the most boring part of cloud infrastructure, aside from layer 1 signaling mechanisms maybe. Nonetheless, I’m excited to see this launch.
The reason is that I/O for storage is becoming a limiting factor in some cloud infrastructure....
