One of the areas where VMware vSphere has had a large advantage over Microsoft Hyper-V has been in the architecture and capabilities of the VMware vSphere Virtual Switch. The most important of these capabilities has been the ability to designate one or more ports on the switch as promiscuous or mirror ports. These ports make a read only copy of all of the data flowing through the switch available to whatever virtual machine is sitting on that port. This is an essential capability for many security products and also performance management solutions like those from ExtraHop Networks that rely upon deep packet inspection to work.

There have recently been a spate of articles and blogs that are attempting to create a contest between “Network Performance Management” tools and “Application Performance Management” tools. This includes a Network Computing survey that finds fault with APM solutions, and a SOA World Magazine comparison that tries to compare the two types of solutions. This is silly and unproductive. It is far more productive to approach this problem from the perspectives of what your needs and applications look like.
One of the great advances provided by virtualization is that a server ceases to become a monolithic combination of hardware and software that is brittle and difficult to manage. Instead a server is encapsulated into a virtual machine which can then be managed independently of its underlying hardware. Since every server is now a file and since files are much easier to manage than hardware/software servers, just putting servers into images was a huge step forward. But as is always the case in this industry where an innovation simply produces a new problem to solve, anointing the image as the unit of management for a server created some problems.

As we have noted before, virtualization and cloud computing are forcing a reinvention of the operations management business on two fronts. The first front is that virtualization and cloud computing introduce new requirements that legacy solutions do not meet and they break legacy products rendering them worse than useless (because the consume resources and money and add no value). The second front is that successful operations management vendors like Veeam, Xangati, VMTurbo, Zenoss, PHD Virtual, SolarWinds, Reflex Systems, VKernel, and VMware have all made it much easier to try and buy operations management solutions leading to a new business model for operations management vendors that makes the existing legacy way of selling enterprise systems management software completely unattractive to customers and irrelevant.

VMware is already the best (most competent) and most important (fastest growing and the source of the most innovation) system software company on the planet. But as successful as VMware has been to date, it is worthwhile to ask what lies ahead – and most importantly in what direction VMware is likely to go on some key business and technical issues. In order to understand the range of choices VMware has it is worth looking at both Microsoft and Oracle as points of reference. Continue reading VMware – The Next Microsoft, or the Next Oracle?
In “CA Starts the Race To Self-Destruction Among the “Big Four” in Virtualization Management” we explained why the big four are not a good choice for managing your virtual infrastructure (and for that matter your private/hybrid/public cloud). There are two top level reasons for this. The first is that virtualization both breaks how legacy management solutions work and introduces a new set of requirements that legacy solutions cannot address. The second is that the management vendors who are finding success in the virtualization market have focused upon an “easy to try, easy to buy, and affordable to own” business strategy that is the opposite of how the big four do business.
