VMware Horizon FLEX. The architecture and the key features

As far back as 2 years ago at VMworld Europe 2014 conference VMware announced the release of the VMware Horizon FLEX solution. It is a virtualization platform for desktops, which allows running virtual machines locally on users’ computers, both on Mac and with Windows, while connection to the company’s datacenter isn’t available. At the same time, the virtual machine utilized by the user can be Windows-based or have guest OS Linux inside. Many virtual infrastructures administrators still remember that before VMware had VMware ACE and VMware View Local Mode products, which passed long ago and now have been replaced with FLEX technology. Since VMware Horizon FLEX 1.9 version, as well as the new versions of Workstation and Fusion desktop platforms, has been released just recently, let’s look closer at the FLEX solution and consider its key features.

VMware Photon OS + Docker Volume Driver = containers architecture on vSphere virtualization platform

Many of you know that VMware has a technology called vSphere Integrated Containers (VIC). It involves launch of Docker (and others) virtualized containers in small virtual machines with a lightweight operating system based on Linux distribution.

This operating system is VMware Photon OS 1.0, which has been finally released just recently. This is the first release version of this operating system from VMware, but in the long view it can become the main platform for virtual appliances by replacing the everlasting SUSE Linux.

How Transparent Page Sharing memory deduplication technology works in VMware vSphere 6.0

You may know that memory page deduplication technology Transparent Page Sharing (TPS) becomes useless with large memory pages (it’s even disabled in the latest versions of VMware vSphere). However, this doesn’t mean that TPS goes into the trash bin, because when lacking resources on the host-server, ESXi may break large pages into small ones and deduplicate them afterwards. In the process, the large pages are prepared for deduplication beforehand: in case the memory workload grows up to a certain limit the large pages a broken into small ones and then, when the workload peaks, forced deduplication cycle is activated.

Evaluation of Performance and Snapshot Consolidation Process Time in VMware vSphere

Snapshots in VMware vSphere often cause various problems with configurations and performance, unless they are properly used – for live backup of virtual machines and temporary keeping VM configuration before the update.

However, using them in large infrastructures is unavoidable. At some point you may need to delete/consolidate virtual machine snapshots (Delete All button in Snapshot Manager), which is quite time-consuming and demanding in terms of storage performance. Thus it would be a good thing to know in advance how much time it takes.
