Welcome to the latest edition of the VMware Technical Journal (VMTJ), Volume 4, Number 1.
At VMware, we have a very clear and focused corporate strategy: Be the leader in the software-defined data center (SDDC), end-user computing (EUC), and hybrid cloud computing (our VMware vCloud® AirTM service).
This issue of VMTJ contains several papers from our EUC organization, and I am grateful to Kit Colbert for acting as the guest editor for this issue. To quote from his introduction in this issue about the work of our EUC teams:
The EUC team’s mission is to enable a secure virtual workspace for work at the speed of life. The reality is that consumerization of IT is bringing more—and more diverse—devices onto company networks. The “one size fits all” one-desktop-per-employee model no longer works. IT now needs to manage a plethora of different devices, enabling rapid delivery of a user’s applications and data to all those devices while at the same time ensuring security and compliance. Users, on the other hand, are demanding a seamless, integrated experience. They want information and apps at their fingertips and want to be able to set down one device, pick up another, and start right where they left off. These are some challenging requirements!
This is certainly true. We are in the midst of a major shift in how workers go about their computing tasks in the enterprise, where mobile applications and cloud computing are rapidly becoming the primary modes of computing. Kit’s introduction describes the EUC papers in this issue, as well as a paper by Ravi Soundararajan and Shishir Kakaraddi on how social networking concepts can be applied to system performance management.
In addition to the papers from EUC and the Soundararajan/Kakaraddi paper, this issue contains two papers from professors and graduate students from Georgia Tech. The first, “Reducing Cache-Associated Context- Switch Performance Penalty Using Elastic Time Slicing” by Jammula et al., describes a novel hardware/software approach for implementing variable time slicing to minimize the context-switch overhead associated with cache-warmup slowdowns that can impact certain workloads, particularly in virtualized environments. The second, “FlashStream: A Multitiered Storage Architecture in Data Centers for Adaptive HTTP Streaming” by Moonkyung Ryu and Professor Umakishore Ramachandran, describes a design for a storage system that
is optimized for video streaming. This paper is an expanded version of a paper that appeared in ACM Multimedia 2013.
We take great pride in the work of our talented engineers, and we appreciate the excellent work and significant contributions of our colleagues in academia. As always, we welcome your comments on this issue of the VMware Technical Journal.
