Top Virtualization Articles to Start Your Week

By Zerto, on 3 February, 2013

Some light reading for when you need your Virtualization and Data Protection fix!  Here are the virtualization articles we found interesting in the last week:

1. For pure awesomeness rolled up into a blog post – check out “What Jaws Taught me About Information Technology” well done @discoposse !

2. TheInfoPro, part of 451 Research, released its ‘Servers and Virtualization Study,’ which was based on live interviews with “server professionals and primary decision-makers at large and midsize enterprises” in North America and Europe. One interesting take-away: “Average virtualization levels have increased 13% from last year to 51%, with a notable increase at the higher levels, roughly doubling the number of organizations virtualizing production applications.”

3. This one’s useful – outside the scope of data protection and more focused on incident management in virtualized environments – but well written and interesting – here’s an excerpt from the post “5 steps to Incident Management in a Virtualized environment,” from the InfoSec Institute:

“Incident Management (IM) is a critical component to a security program. Traditional IM approaches are not always effective in a partial or completely virtualized data centers and this article discusses five steps that lead to a tight integration of VM and existing incident response processes. They examine and help remedy system, network, and process design challenges associated with VM placement  incident detection and containment, and business process recovery unique to virtualization.” Read More…

4. Finally – a topic that can never be discussed too much – when to upgrade to the next VMWare version.  This time, addressed by Trevor Pott at SearchVmware, “Ready for a vSphere 5.1 upgrade? Depends on your current version

Happy Superbowl Sunday and have a great week!

    A couple of thugohts come to mind.First, in my opinion, virtualization or abstraction, like entropy, grows. I don’t recall any instance in my career of a layer of abstraction being removed from a solution, whether that be in storage, processing, communication protocol or software design.Second, virtualization exists for two reasons, being 1) to simplify aspects of system usage, at least from the perspective of a subset of the system users, and 2) because integration happens. The first is perhaps obvious, but the second deserves a little elaboration. I have this file folder on my titled What to do with all that annoying excess storage capacity for example. I don’t open it much these days, but it does serve to remind me of the disc industry’s continued fascination with areal density, and how the mismatch in the pace of different technology trajectories creates problems that are often addressed by, you guessed it, additional layers of virtualization or abstraction. I’m about to pen another folder with What to do with all that annoying excess CPU capacity .Of course virtualization comes at a price, being system complexity. The distance grows between your fingertips on the keyboard, and the flux reversal on magnetic media where your data is persisted. Distance here is measured in the number of layers of abstraction, virtualization, APIs, nested protocol, encryption, encoding, replication, migration, , etc. It will continue to grow, and it continues to provide rich opportunity for system and storage management utilities.
