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
VMware customers who have needed to manage the Availability, Resource Utilization, Capacity, Configuration, and the impacts of these areas upon system performance have had a rich set of vendors to choose from to get these types of solutions. Up until today, a comprehensive solution in this area has not been available from VMware itself. VMware has now announced vCenter Operations, three editions of which are intended to address these issues. Continue reading vCenter Operations – vSphere Performance, Capacity and Configuration Management with Self Learning Analytics
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.

On 9/28/2010 CA Technologies announced that it will acquire Hyperformix. Hyperformix is a vendor that delivers capacity management and performance management solutions for physical and virtual environments.
With this announcement CA formerly enters the capacity planning, and more importantly the capacity management market for virtual environments and their underlying physical infrastructures. It is important to distinguish between the capacity planning and management use cases for this product set. Capacity Planning is something that enterprises have been doing for years and is a periodic activity that is focused upon making sure that an application system does not run out of capacity for a critical hardware resource inside of the purchase cycle for more of that resource. Continue reading CA Acquires Hyperformix – Bolsters Predictive IT Management Capabilities
While it may seem that with Integrien VMware has acquired yet one more piece of the puzzle (a puzzle whose final form no one knows), this acquisition is perhaps one of the most significant if not the most significant that VMware has done. To understand the significance of this acquisition, one has to step back and examine a bit of history in the Systems Management business. Continue reading The Significance of the VMware Integrien Acquisition
For quite some time VMware has been letting it known that it intends to be a management software vendor on top of its own virtualization platform. In fact VMware has already taken a series of steps that prove that management is not just an intention, but will be a strategy fulfilled with product deliveries. These actions include buying B-hive and delivering the resulting AppSpeed product, buying the four management products from EMC/Ionix which resulted in Configuration Manager, Application Discovery Manager, and Service Manager (Fastscale seems to have gotten lost in the shuffle), developing and delivering CapacityIQ, buying SpringSource with which came Hyperic and integrating it into vCenter, and delivering Chargeback.
