You don't deliver applications in a vacuum. Applications and the infrastructure that supports them are dynamic systems that change over time. Unrelated system using the same network, servers, and storage can adversely impact application performance. With virtualization, the risk of one virtual server impacting another is quite real. Our End to End Application Performance Management (APM) Tech Center delivers best practices, emerging trends, new products and strategies to help you delivery applications effectively.

The Importance Of Correcting Packet Loss In VDI
March 30, 2011 11:13 AM
Posted by David Greenfield
Recently, on the LinkedIN WAN optimization professionals group, I participated in a conversation around whether virtual desktop infrastructure (VDI) is ready for the WAN. Face it, delivering responsive VDI over the WAN is going to be a challenge. One of the interesting points that came up was the importance of correcting for packet loss when considering WAN optimizers.

What WAN Optimizers Can Learn From Firewalls
March 11, 2011 10:28 AM
Posted by David Greenfield
Listening to the give and take about WAN optimizers made me remember another battle between networking giants. It was nearly 10 years ago, during the early days of firewalls, when it seemed Marcus Ranum, then with Network FlightRecorder, would go head-to-head with Check Point's Gil Schwed on a weekly basis. Ranum was among the early creators of the application proxy and was vociferous about the value of delivering a firewall that terminated and inspected every session before passing the contents onto the destination. It was very effective, very secure and yet ultimately eclipsed by competing approaches.

Cloud Connect Is All About Automation

Automation. That is the theme I continue to come back to while at Cloud Connect. I think organizations are going to be getting the most benefit from automation in the near term, and automation is one of the many steps on the road to private cloud computing. Automation, when done right, can save you and your staff loads of work and can ensure that deployments go more smoothly. I sat down with representatives from VMWare, Gale Technologies, HP, TransLattice and Cloud.com, and got the lowdown on automation and private cloud.

The First IPv6 WAN Optimizer: Speed At What Price?
February 16, 2011 01:57 PM
Posted by David Greenfield
Last week, Blue Coat upgraded its MACH5 to become the industry's first IPv6-compatible WAN optimizer. WAN optimizers have long supported tunneled IPv6 over IPv4, but the MACH5 is the first WAN optimization appliance to accelerate native IPv6--and then some. The MACH5 is actually a very sophisticated IPv6 application layer gateway (ALG), providing IPv6 connectivity, security and optimization in a single device. Yet it's precisely its sophistication that raises questions around device scalability and price.

WAN Optimization and the VDI Challenge
February 14, 2011 11:56 AM
Posted by David Greenfield
I was sitting in on a peer-to-peer exchange about virtual desktop infrastructure (VDI) hosted by Wikibon and listening to how great VDI is for organizations. I asked about multisite VDI and what recommendations people had for implementing VDI between sites. The speaker paused and said that she hadn't see any multisite implementations. No surprise there. VDI itself is still in its infancy, but it hit me once again that if organizations are going to see VDI's benefits at the remote office, they've got to pay close attention to their WAN acceleration layer.

Data Centers: The Next Frontier For WAN Optimizers?
January 06, 2011 11:04 AM
Posted by David Greenfield
Signs of the increasingly pivotal role that WAN optimization is playing in the enterprise can be seen in the emergence of hybrid cloud architectures within corporate networks. As Mike so poignantly pointed out in his blog, the simple ability to run a VM does not make an application ready for the cloud. If developers are to leverage on-demand services, such as Amazon's EC2, they need to rethink how they architect their software to leverage a hybrid cloud environment.
