Consumers and business-users can't get enough of Web 2.0 applications. Businesses love the quick deployment, adaptability, and potential to drive sales and increase customer engagement. But Web 2.0 apps have a catch: an insatiable appetite for server computing power.All the instant interactivity that's so seductive about Web 2.0 demands computing power and businesses running successful Web 2.0 apps face the prospect of adding server rack after server rack to face demand. Or as an official Citrix statement put it:
"While Web 2.0 applications are ushering in a new era of enhanced functionality and responsiveness for end users, they are highly inefficient when it comes to server computing resources. In order to create a rich interactive experience, Web 2.0 applications need to maintain a one-to-one user connection to backend servers for extended periods, which severely taxes datacenter resources and adversely impacts performance and scalability."
So how to deliver all the features of Web 2.0 apps without going on a server spending spree? Fake it.
That's the idea behind Citrix's addition of push technology to its NetScaler Web application delivery appliance line. The push technology allows a NetScaler system deployed in front of the data center to send date to application users -- reliving the pressure on backend server infrastructure.
Or as Citrix claimed in an official statement:
"This approach can be used to deliver continuous streams of new or updated information, creating the illusion of real-time interaction."
The new Citrix offering is immediately for the NetScaler Enterprise and Platinum editions and current customers get a free upgrade.
