VMware Technical Journal, Spring 2012

The VMware Technical Journal is a new publication for the company. We are looking forward to producing future journal issues at regular intervals to highlight the R&D efforts taking place in several different areas of engineering. Our current issue includes papers related to distributed resource management, user experience monitoring, and statistics collection frameworks for virtualized environments, along with several other topics. In future issues we will highlight other areas of VMware R&D, including Cloud Application Platform and End User Computing, and research collaborations with academic partners.

The hardcopies of the journal and USBs loaded with the journal can be requested by sending a request to vmtj@vmware.com.


Hello and welcome to the inaugural issue of the VMware Technical Journal! This journal is completely driven by VMware engineers who enjoy telling the details of interesting projects and products, sharing their passion for virtualization and cloud computing, and celebrating the innovation occurring all around our industry.

It’s definitely an exciting time to be at VMware. We’re at a point in time when nearly 60% of all server applications in the world are running virtualized, the large majority of those on VMware’s virtualization platform. We’re also becoming very popular in the “desktop computing” space as enterprises rapidly move into the Post-PC era characterized by mobile devices, SaaS applications, and anywhere/anytime computing. This popularity means that many great partners want to integrate with our products, that our innovations can have a dramatic impact, and that we have an opportunity to extend our products into many adjacent technology areas. As a result, our engineering team ends up working in almost every area of system software. The VMware Technical Journal appropriately reflects this breadth of focus.

This inaugural issue includes articles on our core vSphere technologies as well as on our newer SaaS-related management tools. We’re also providing a look behind the product creation process with articles that cover the testing of vSphere quality, measuring performance, and building great user-experiences. We also close the journal with a great look at using all of these products in a very high-stress, high-demand environment… the VMworld Labs! We sincerely hope you enjoy this first edition. We welcome your comments and ideas for future articles. Until next time, happy computing!
