The Virtualization Practice

Data Center Virtualization

Data Center Virtualization covers virtualizing servers, networks, and storage delivering server consolidation, CAPEX savings, IT agility, and improved management. Major areas of focus include the tradeoffs between various virtualization platforms (VMware vSphere, Microsoft Hyper-V and Red Hat KVM), the evolution of hypervisors into data center management platforms, ...
VMware’s Software Defined Data Center strategy, and how the SDDC is spurring innovation in storage, networking and server hardware. Covered vendors indlude VMware, Microsoft, Red Hat, CloudPhysics, Hotlink, Tintri, and VMTurbo.

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.

Countdown to Launch

Friday was the day that the last space shuttle will be launch in to space. The shuttle Atlantis is on the launch pad and ready to go. As I watched the clock countdown to zero, I found myself reflecting on the idea that this launch will be the very last space shuttle flight. I grew up in Florida and have been able to walk outside and watch the shuttles, over the years, launch into space. I have enjoyed watching the launches as well as feeling the sonic booms when the shuttle would fly overhead on the way to the runway for touchdown. For me and many others, this launch signifies the end of an era and the start of something new.

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.

News: VMTurbo Raises the Bar for Free vSphere Monitoring – Again

VMTurbo’s unique Service Assurance capabilities (and the ability to charge for them in the paid products) allows VMTurbo to make baseline performance and capacity management for vSphere environments available for free. This represents a significant redefinition of where the value is and where the value is not in the virtualization performance management business.

Applications Performance Profiling is an essential step in the process of virtualizing business critical and performance critical applications. In this case “performance” means response time not resource utilization. The virtualization team should go even further and commit to meeting response time based SLA’s for business and performance critical virtualized applications.

Security in the cloud and the virtual environment is ‘all about the data’ and not specifically about any other subsystem. It is about the data. As such the data has something it knows (the contents of the data), something it is (its signature), and something it has (its digital rights) and since it has these three elements, the data has all it has identity. However, protecting the data requires us to put things between the data and the real world such as firewalls, and complex role based access controls, as well as methods to replicate the data to other locations in a non-intrusive mechanism. The goal to such replication could be to ensure multiple sites have the same data (such as a hot-site) or to have the data available in another locations in case of disaster.
