The Virtualization Practice

IT as a Service

IT as a Service (ITaaS) covers private clouds hybrid clouds and the cloud management offerings used to create and manage these clouds. This includes coverage of Infrastructure as a Service (IaaS) private and hybrid cloud offerings, Platform as a Service (PaaS) private and hybrid cloud offerings, and Software as a Service (SaaS). ...
Emerging areas like Desktop as a Service (DaaS), Storage as a Service, and Applications as a Service are also covered. The key issues covered include which enterprise applications and use cases are appropriate for private and hybrid clouds, and how vendors should select the cloud management offerings that are going to be used to manage these various types of cloud services. Covered vendors include VMware (vCloud Automation Center), VirtuStream, CloudBolt Software, Intigua, ElasticBox, ServiceMesh, Cloudsidekick, and Puppet Labs.

Over the last few months we have identified a trend towards “diversity” in the PaaS provider marketplace. Platform as a Service has become Platforms as a Service, the providers are offering multiple choices at each layer of the platform infrastructure, and seeing their role as automating the provisioning of properly-configured instances as required at each layer of the stack.

On Aug 2nd, there was another entrant to this “diverse” PaaS provider marketplace called Cumulogic, a startup with a PaaS cloud positioned alongside Red Hat OpenShift and VMware CloudFoundry that we identified earlier.

VMware has made significant changes to the recently announced vRAM based pricing. The single most significant change is that potential barriers to the virtualization of memory intensive business critical applications have been eliminated by ensuring that no application no matter how big can cause a charge of more than 96GB to be levied against the pool of available vRAM.

Performance Management for Desktop Virtualization (VDI) and Presentation Virtualization (SBC)

Ovum’s research found that desktop virtualization currently represents approximately 15% of the business PC market. However, this figure is dominated by the Presentation Virtualization model (12%), typically used in call datacenter-type environments, and has been for the last 10 years. If PV/terminal services are excluded, the next generation of solutions aimed at CIOs, from the likes of Citrix, Quest and VMware, hold less then 3% of the market, showing that many CIOs are holding back from taking the plunge.

VMware – A Train with an Engine, 3 Boxcars, and a Caboose

VMware is already the most important, and with vSphere the best systems software vendor on the planet. This is true not only based upon the current success of the vSphere platform, but the quality of the long term strategies in place for vFabric, vCloud, and vCenter. With vSphere 5, VMware can ill afford distractions that detract from the momentum of the attack upon the remaining 60% that is not virtualized. The strategic investments in vFabric, vCloud, and vCenter then call into question of viability of having a desktop virtualization business (View) that is today in product and tomorrow in vision a minor subset of what Citrix is delivering and articulating.

The single most dangerous part of this new pricing (to VMware) is rooted in the following fact. What is left to virtualize is very different from what has been virtualized to date. If what VMware has done is change its licensing around to replace one metric (cores) with another (vRAM) in a manner that would have allowed it to get the same revenue from its existing customers to date, then VMware has totally missed the boat.

Over the last few months an additional subproject codenamed Quantum has emerged which deals explicitly with networking and has particpation from networking giants Intel and Cisco as well as from Citrix. It’s a mechanism for defining network topologies aimed at providing Layer-2 network connectivity for VM instances running in clouds based on the OpenStack cloud fabric. It is designed to be extensible to allow higher-level services (VPN, QoS, etc) to be built on top, and to cleanly handle the “edge of network” problem (i.e. the binding of the cloud into the internet).

vSphere 5 – Virtualize Business Critical Applications with Confidence

Just in time for the adoption of vSphere 5 by enterprises seeking to virtualize business critical and performance critical applications, AppFirst, BlueStripe, and ExtraHop have pioneered a new category of APM solutions. This new category is focused upon allowing IT to take responsibility for applications response time for every application running in production. This is an essential step on the road toward virtualizing the 60% of the applications that remain on physical hardware.

ExtraHop has now made an important contribution to the question of how to measure applications performance across physical and virtual environments. Properly deployed ExtraHop can play a critical role in helping enterprises virtualize the 60% of the remaining applications that are “hard”, “performance critical”, and “business critical”. As vSphere 5.0 is right around the corner, the timing could not be better.

What is still missing here is any kind of an end-to-end view of infrastructure latency that is also real time, deterministic and comprehensive. The marrying of the SAN point of view with the IP network point of view is the obvious combination. The hard issue here will be the identification of the applications so that these view of infrastructure performance can be surfaced on a per application basis. In summary, we have a long way to go here, and this just might be why so many of those virtualization projects for business critical and performance critical applications are having so much trouble getting traction.
