This is the third article in a series about data locality in hyperconverged infrastructure (HCI). In the first article, I discussed basic math around storage network IO and the effect of data locality on the storage network load. In the second, I examined the impact of HCI configurations with more than two copies of data. I’ll wrap up with a look at how data locality is usually incomplete and at a special case of data locality.

As I think back over the journey from physical, to virtual, to cloud, to containers, there is one technology that stands out—one that has fundamentally moved our mindset away from static resources and has caused a serious shift in how we license, secure, and even think about technology. For me, that shift started the first time I saw vMotion in action (vMotion moves a virtual machine from one host to another without taking the virtual machine down or stopping the running application, and without disaster striking). This one instance shifted my worldview of computing from one in which resources are static to one where they are truly virtual—where the underlying infrastructure in many ways just did not matter. This one technology paved the way for the future of computing.
Welcome to The Virtualization Practice’s week-long coverage of VMworld US 2015. Tune in all week for our daily recap of the major announcements and highlights from the world’s premier virtualization and cloud conference.
VMworld US 2015 continued in force yesterday, beginning with a long but powerful general session/keynote talk. Carl Eschenbach, VMware’s president and COO, set the stage for a slew of announcements around VMware’s “One Cloud, Any Application, Any Device” approach to computing and a seamless federation of all types of clouds, supporting both traditional and new cloud-native applications. A variety of VMware leaders joined him on stage to talk about the various aspects of these announcements and how they mesh with their overall strategy. While each of these areas could give rise a whole series of posts by themselves, I’ll summarize the major points.
During VMware’s online launch event, the company announced the latest release of its flagship product, vSphere 6.0. This release has a lot of great features and enhancements. In this article, I zero in on one specific enhancement: the evolution of vMotion technology into vDistance technology.
Google has delivered live migration in its Google Compute Engine cloud offering. Now comes word from Barb Darrow at Gigaom that Amazon is working on live migration as well. Is it possible that the cloud bambies are waking up to the fact that not all applications are stateless and that for many applications, shutting down instances is simply unacceptable? Are the cloud bambies waking up to enterprise requirements for availability and performance management?
On 9/8 was held the Virtualization Security Podcast featuring Phil Cox, Director of Security and Compliance at RightScale, to discuss the impact of and need for automation of cloud security. Given that we create clouds by automating deployment of workloads we also need to automate the security of those workloads during the same deployment. This podcast delves into that need, and touches on where over automation is also a problem.
