2012: The Beginning of the End for Virtualization Management?

In the APM Digest, Andi Mann VP of Strategic Solutions for CA, predicted that “in 3-5 years Virtual System Management vendors will no longer survive, as virtualization becomes a core part of the enterprise compute fabric. Three years later this trend has definitely started, and will accelerate in 2012 as IT turns instead to hybrid IT management, recognizing that silos of standalone virtualization management is a costly and inefficient burden. Maybe 2012 is not the end of Virtualization Management, but it is going to be the start of the demise“. Continue reading 2012: The Beginning of the End for Virtualization Management?

5 Starting Steps to Protect Your Virtual and Cloud Environments

More and more is coming out about the attack from a MacDonald’s that left an organization crippled for a bit of time. The final tally was that the recently fired employee was able to delete 15 VMs before either being caught or he gave up. On twitter, it was commented that the administrator must not have been a powershell programmer because in the time it takes to delete 15 VMs by hand, a powershell script could have removed 100s. Or perhaps the ‘Bad Actor’ was trying to not be discovered. In either case, this has prompted discussions across the twitter-sphere, blog-sphere, and within organizations about how to secure from such attacks.

Your VMworld 2011 Enterprise Virtualization Performance and Capacity Management Short List

With VMworld 2011 around the corner whose booth’s should you visit? Well if you are an enterprise with a large scale virtualization initiative then performance and capacity management should be at or near the top of your mind.  VMware clearly agrees as they have announced and delivered vCenter Operations specifically to meet this need. So after you go see vC Ops Enterprise, what else should you go see?  Continue reading Your VMworld 2011 Enterprise Virtualization Performance and Capacity Management Short List

Security of Performance and Management tools within the Virtual Environment

One of the basic tenants of virtualization security is to protect the management components of your virtualization hosts by placing these all important components on a separate network. These components often include management servers such as SCOM, vCenter, XenCenter, VirtManager, etc. as well as the management appliances of your virtualization hosts. In essence, the use of a properly configured, firewalled, and monitored virtualization management network would be the simplest and most effective security measure that can be made to day within any virtual environment. A message shared by Citrix, VMware, myself, and many others.

The problem is that not everything is as black and white as security folks desire. If we implement performance and other management tools, we often need to expose part of our all important virtualization management network to others. But how do we do this safely, securely, with minimal impact to usability? Why do we need to this is also another question. You just have to take one look at the Virtualization ASsessment TOolkit (Vasto) to realize the importance of this security requirement. But the question still exists, how do you implement other necessary tools within your virtual environment without impacting usability? Which we discussed on the May 5th Virtualization Security Podcast. Continue reading Security of Performance and Management tools within the Virtual Environment

A Perfect Storm in Availability and Performance Monitoring

Monitoring computing infrastructure and applications for capacity, availability, and performance is a business that has been around for a long time – in fact for just about as long as computers have been used for business critical applications (since the mainframe lead era of the 1960’s). Since that time several waves of change have swept through the computer industry, and with each wave of change has come new computing architectures, new applications, requirements for monitoring and new monitoring approaches. Those waves have included mini-computers, personal computers, LAN based file sharing, client/server based computing, Internet (browser) based computing, N-tier SOA based applications, and now include agile development, virtualization, cloud based computing, and the proliferation of mobile based applications.

Performance Monitoring for IT as a Service

In “IT as a Service Reference Architecture“, we presented a a categorization of the the functionality and the products that are needed in order to construct an IT as a Service system. Purposely missing from this architecture was the question of how to monitor the performance of the services delivered from the service catalog via the underlying policies and automation in the IT as a Service stack.
