Nimbula is an Infrastructure as a Service (IaaS) software stack analogous in its target market and its business model to commercial software like vCloud. It sits alongside a number of open source software products like Eucalyptus, Cloud.com (Citrix) and OpenStac k(Rackspace et al.) as well as the Amazon Web Service, and other hosted services.
I have had the opportunity to perform a few VMware Capacity Planner assessments over the years and I have been, more the most part, pretty happy with the process and the results of the reports. The assessment is really pretty straight forward. We had physical servers to the project, making sure we have proper permissions to perform all the tasks and then let the process run over an extended period of time. For the most part, this way of sampling over an extended time frame will give you a very good idea what can be virtualized and the number of hosts that will be needed.
Less than 5% of the applications that matter to enterprises world wide are under management by an APM solution that can help ensure application response time, application availability and the integrity of the critical transactions within the application. This is because first generation APM solutions have been too expensive to purchase, too limited in their scope and too expensive to configure, maintain and own.

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.
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 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.
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.
