vSphere Auto Deploy

The Auto Deploy is one of the underestimated vSphere features. I have seen many vSphere Designs where using Auto Deploy was outlined as overcomplicating and manual build of ESXi servers was preferred. That is pretty frustrating as we, as IT professionals, strive to automate as much as possible in our day to day work.
Configuring Auto Deploy is definitely not as simple as VSAN for instance, but using Auto Deploy really pays off when you manage hundreds and thousands of ESXi hosts.
The HTML5 Web Client Fling

VMware has long stopped adding newly released features and functionality into the old С# client in hopes to push their customers into using the vSphere Web Client. However, even by restricting new features only to the Web Client adoption has been slow – partly due to change, no one likes change, but mostly due to the slowness and the overall sluggishness that is experienced using the flash based vSphere Web Client.
Just this year with the release of vSphere 6.0 Update 2 we saw something called the “Embedded Host Client” make its way into a release – allowing us to manage our individual ESXi hosts with an HTML5 based interface built right into the product. Now we are seeing this same type of HTML5 technology being used with the vSphere HTML5 Web Client fling being released.
Instant Clone functionality in VMware Horizon 7 – how quickly and efficiently it works

As far back as at VMworld 2014, VMware announced VMware Project Fargo technology, also broadly known as VMFork. It allows to make a working copy of a running virtual machine on VMware vSphere platform very fast.
The VMFork technology involves on-the-fly creation of virtual machine clone (VMX-file and process in memory), which uses the same memory (Shared memory) that the parent VM does. At the same time, the child VM cannot write to the shared memory and uses the allocated memory to write its own data. With disks, it is just the same: with the Copy-on-write technology, the changes of the parent VM base disk are written to the child VM delta disk:
Comparing vSphere Distributed Switch and Cisco Nexus 1000v switch

When time comes to deciding whether to go with vSphere Distributed Switch or Cisco Nexus 1000v it is hard to tell which product is superior and you find many different and quite contradictory opinions.
While quite often it is the political decision based on the answer to the question “Who is going to manage the virtual networking?” there are many other aspects you, as an infrastructure designer, should be aware of.
Recently VMware announced End of Sale of Nexus 1000v which caused some confusion amongst clients. I know customers who were pretty sure Cisco discontinued Nexus 1000v, but rest assured, Cisco is still fully committed to continue development of virtual networking and to support Nexus 1000v in the latest and future versions of vSphere.
