I’ve been maintaining my own web server for this WordPress blog for several years now, dating back to 2005 when I first starting using CentOS 4 to run my website. Those were the days I switched from authoring websites with Dreamweaver and FTP, to using WordPress and ditching those antiquated tools alltogether. Talking of antiquated, I’ve been working with Unix since 1992 and was a Linux sysadmin for an ISP for several years after that. I’ve also been learning along the way with each release of CentOS/RHEL, and I have taken much more notice of security hardening including the use of SELinux.

For as long as I can remember I have never really had what you would call a ‘typical’ home network. Back in the early 2000s I had a Cisco home lab which included two Cisco 2610 routers that a friend gave me. I ended up using these to create a home DMZ for my WiFi network, which was still WEP in those days so I was a little paranoid about security. While this was great for my study, I was also able to use it for real world purposes. One application was my car. That’s right, in 2004 I had a WiFi connected car. This was before I had kids, so I decided to install a Shuttle XPC in the back of my Honda Accord Type-R], with a touch screen in the front console with full-screen Winamp for my MP3 collection. I won a few trophies at the UK sound-off competitions back then. All good fun.

This has been an exciting time for the IT industry. At VMworld US 2016 (August 29th 2015) we had the announcement of VMware Cloud Foundation becoming an integral part of IBM SoftLayer and then we had the news of the strategic partnership with Amazon Web Services (AWS) and VMware (October 13th 2016). VMware Cloud Foundation is a shift in cloud infrastructure that enables the Software Defined Data Center (SDDC). This is significant because what we know as the SDDC, with technology such as VMware Horizon, NSX and Virtual SAN, can now be consumed and offered by service providers in a unique way.
At the core is SDDC Manager and lifecycle management (LCM) which allows a fully automated deployment, configuration and patching & upgrades. But what does the architecture look like behind VMware Cloud Foundation? Let’s take a closer look.

Since I published the Horizon 7 Network Ports diagram with the latest release of Horizon 7, I’ve been frequently asked about the connection flow between the Horizon Client and the virtual desktop. VMware Horizon supports RDP, PCoIP and now Blast Extreme. I’ll start with PCoIP and then we’ll look at Blast Extreme. I’d also like to reference this excellent article by Mark Benson, Load Balancing with VMware Access Point.
The connection flow of the Horizon Client is mostly the same with Horizon 7, Horizon Air or Horizon DaaS. There may be differences in external load-balancing, Security Server or Access Point, and external URL configuration, but for this post I’ll focus on the Horizon Client itself and the aforementioned protocols.
