When reading about VMware’s release View 4.6 this week, I can’t help thinking that they might be missing the big picture. It’s almost like they want to sell phone service without a long distance calling plan.
While early VMware View supported remote access directly through a security server via RDP (Remote Display Protocol), when finally adding PCoIP (Personal Computer over Internet Protocol) support, it didn’t include an option for remote access, so companies had to either implement an expensive non-SSL based VPN with custom configured gateways for the rare use of the PCoIP port, or revert to RDP over the WAN, which carries performance issues.
VMware View 4.6 was the long awaited answer to simplify the Remote Access problem. However, VMware elected not to support SSL, so administrators will need to open the PCoIP port 4172 in the DMZ, but users will also have to make sure they have port 4172 open on their local firewalls – yes even on their laptops and PCs! As a result, the picture really doesn’t change for VMware customers. They might be able to get remote access with PCoIP to work over the WAN if they absolutely need it, and if they have control over remote and local networks. However, given the complexity and cost to set it up, it most likely will just not be used leaving users to suffer with RDP performance.
Whether you are trying to centralize desktop management, secure data, or empower users to work anywhere from the device of their choice, a core element of desktop virtualization has to be ubiquitous access that is simple, easy and transparent especially for non-techie users – no messing around with end-user device and personal firewall configuration settings!
That means anywhere, any device, any app or desktop
A simpler – yet well proven – approach The right approach is to start with a TCP-IP based protocol that can be effectively routed over the Internet through a secure HTTP / SSL channel. We have all seen the rapid adoption of SSL-browser enabled devices beyond traditional PCs or Macs. This means that any computing device, whether it is a PC, Mac, a tablet or a smartphone – connected to the Internet with a browser can effectively communicate with a high degree of security and privacy. These devices are used every day to secure billions of dollars in ecommerce and sensitive corporate data and have emerged as the standard for remote access. The ubiquity of SSL/TLS ensures that port 443 will be open on firewalls – both on users’ computing PCs, Macs, tablets and smartphones as well enterprises datacenters.
Next, with SSL traffic, IT administrators can leverage their existing investment in industry standard and carrier-grade SSL offload-accelerators to scale desktop delivery to several tens of thousands of concurrent desktop users.
Finally, TCP-IP packets lend themselves well to WAN acceleration and optimization. This is particularly true for remote desktop and application display as so much of the user interface is repeated. This is true for a single user and common across multiple users which make local caching extremely effective at boosting performance and reducing bandwidth consumption.
Citrix has been building solutions for anytime access to apps and desktops for over 25 years. The strategic investments made in networking technologies were designed to solve the problems of delivering a seamless, secure, high performance user experience over difficult networks. Citrix HDX technologies, including ICA, the gold standard in remote protocol technologies, were developed to leverage best practices in secure internet-based communications enabling seamless SSL-enabled remote access and WAN acceleration and optimization.
Just last month, Citrix announced that it is now including HDX WAN Optimization powered by Branch Repeater in XenDesktop Platinum. Combined with Citrix Access Gateway (also included with XenDesktop) branch-based and remote users on virtually any network can get the full benefit of a high-definition user experience while accessing a complete range of virtual desktop delivery options and on-demand apps that can match any use case:
-Virtual desktops , local or hosted virtual machines
-Shared hosted desktops
-Hosted or streamed applications
-and even secure, centrally provisioned single sign on (SSO) to web and SaaS applications with Open Cloud Access (OCA)
