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.

VMworld EMEA, IPExpo, The ExecEvent, Citrix Synergy, oh my!

This month (October 2011) there are a slew of conferences on virtualization and cloud technologies being held in Europe. The question becomes which to attend! If you are in the United States, this could be expensive considering the current Euro to Dollar exchange rate but if you are already in Europe one of these events is well worth attending, each has there own take and focus. But after the success of VMworld US, is there anything more to announce?

Whether you are building a new or adding to an existing virtual or cloud environment on a shoestring budget, whether for work or for home use, there is quite a bit to consider before you purchase anything and it all boils down to your requirements which will dictate the technology you need for your virtual environment. In addition, this is a perfect time to address any deficiencies in your environment to not only address capacity issues, requirements, and security. Along with those considerations, planning the environment for the next three to five years can help shape the overall design. In fact that design, will be based on the answers from a growing list of questions.

Cloud Performance – Learning from SalesForce.com

The focus upon sharing real response time and transaction load data by SalesForce.com is notable when compared with the pre-historic approach to performance that is used by many cloud vendors (and for a matter of fact many enterprise IT organizations). Response Time correlates directly to end user experience and at the end of the day that is all that matters. Hopefully the industry will learn from SalesForce.com and advance this concept further.

Since the introduction of virtualization there has been sheer joy and excitement when having to work with application owners on the amount of resources they will need and not what they really think they want. I have seen all kinds of minimum, maximum, and special recommendation for all kinds of application over the years. In most cases, applications have evolved to be able to thrive in a virtual environment without too many limitations. Now it seems we have to verify which VMware features are fully supported with certain virtualized application also.

Confio Addresses a “Dark Corner” in Virtualized Database Performance

Confio IgniteVM uniquely provides a consolidated view of resource utilization and latency across database servers like Oracle, SQL Server, DB2, and Sybase and the virtual machine layer, the physical host layer and the storage layer. This provides a valuable performance management perspective to DBA’s as well as to the virtualization team that often is held responsible for performance issues in database based applications.

Is it Time to Reorganize Data Center Operations?

If automated IT Operations is going to succeed and deliver its promised benefits then IT Operations is going to have to get reorganized – with supporting hardware teams part of the virtualization team. Furthermore Application Operations will have to be instantiated as a function that is responsible for the actual service level delivered by the applications to their constituents.

VMware Articulates a Compelling Management Vision – Automated Service Assurance

VMware deserves an enormous amount of credit for promising to reinvent IT Operations around automation and the guaranteed performance of applications. VMware either has or is working on all of the building blocks required to execute upon this vision for the vSphere platform. The combination of innovation by VMware, and by the third party ecosystem on this front will create a new compelling benefit to virtualization, that will allow virtualization to comfortably address business critical and performance critical applications.

If there was one thing I saw and heard about at VMworld, was the number of third party collaborations that were taking place. While not explicitly stated by VMware at VMworld, the show floor had many different collaborations that were taking place. This level of collaboration shows a level of maturity within the virtualization and cloud vendor ecosystems. A maturity, that shows that the vendors understand the benefits of leveraging other companies to lower their overall costs while producing better and more attractive products. Some of the collaborations I saw where purely the resale of products, while others were integrations between products.
