These are unpredictable and unsettling times. Like all of you, I am watching events unfold in the global response to COVID-19, and I am doing what is best for my family, the Zscaler family, and Zscaler customers and partners. Zscaler’s mission is to provide secure, fast, and reliable access to applications, no matter where they are hosted, and no matter where users connect. Zscaler is playing a pivotal role for enterprises as they respond to the crisis: We have an obligation to help customers keep employees safe and productive as they work remotely.

As virtual environments scale, understanding how each virtual machine impacts the underlying infrastructure becomes a necessity for efficient data center design and timely issue diagnosis. Capturing this information, however, typically requires complex and costly manual processes. These issues are often particularly challenging across the network, generating a “fog” that hides data congestion and impedes identifying a resolution.

Virtualization as a concept is not new; computational environment virtualization has been around since the first mainframe systems. But recently, the term “virtualization” has become ubiquitous, representing any type of process obfuscation where a process is somehow removed from its physical operating environment. Because of this ambiguity, virtualization can almost be applied to any and all parts of an IT infrastructure. For example, mobile device emulators are a form of virtualization because the hardware platform normally required to run the mobile operating system has been emulated, removing the OS binding from the hardware it was written for. But this is just one example of one type of virtualization; there are many defi nitions of the term “virtualization” fl oating around in the current lexicon, and all (or at least most) of them are correct, which can be quite confusing.

Intel Page Modification Logging (PML) is a novel hardware feature for tracking virtual machine (VM) accessed memory pages. This task is essential in today’s data centers since it allows, among others, checkpointing, live migration and working set size (WSS) estimation. Relying on the Xen hypervisor, this paper studies PML from three angles: power consumption, efficiency, and performance impact on user applications. Our findings are as follows. First, PML does not incur any power consumption overhead. Second, PML reduces by up to 10.18% both VM live migration and checkpointing time. Third, PML slightly reduces by up to 0.95% the performance degradation on applications incurred by live migration and checkpointing.
