Citrix’s new Web 2.0 Push technology aims to combat server overload and
sprawl caused by Web 2.0 applications by offloading Web 2.0 workloads, thereby
freeing up bandwidth for line-of-business applications and improving
performance and utilization rates.
Web 2.0 Push will debut as an integrated feature in Citrix’s flagship NetScaler
product line, says Greg Smith, director of product marketing for Citrix. In
addition to performance and utilization rate improvements, Smith says Web 2.0
Push can also help solution providers reduce the number of servers customers
need in their data center as well as lower the costs associated with the
remaining servers.
While Web 2.0 applications bring enhanced functionality, collaboration and
responsiveness for end users, they are a highly inefficient way to use server
computing resources, Smith says.
Creating the rich, interactive experience Web 2.0 applications are known for
requires users to maintain a direct connection to back-end servers for extended
periods, putting strain on data center resources and slowing performance.
“These applications are slowly making their way into the enterprise, but at a
cost,” Smith says. That cost is increased demand on the network and on the
servers that deliver Web 2.0 applications, he says.
“Imagine you have an application pushing rich, interactive features and data to
lots of users,” Smith explains. “The server has to maintain separate
connections with each user, even if it’s doing duplicate work. With Push, it
can push those workloads out to NetScaler, and NetScaler will push to users,”
he says.
By offloading these tasks from servers, Smith says server costs for delivering
these applications can be reduced by five to 10 times, and can increase
utilization rates by as much as 80 percent.
Smith says Citrix resellers have a competitive advantage over other
virtualization and Web 2.0 solutions, since this technology is the first of its
kind. Not only do solution providers benefit from a solution that can save
their customers money and reduce server sprawl and complexity on the front end,
but back-end network administrators and Web application developers also reap
the rewards.
For ISVs and application developers, knowing that their applications won’t
negatively impact data center performance can allow them to make these
applications richer and more complex, since Web 2.0 Push can handle the
workloads better.
Network administrators, too, can ease the
strain on their primary networks, since bandwidth once devoted to Web 2.0
applications is now delivered directly to users, Smith says.
Web 2.0 Push was released in a recent NetScaler build, Smith says, and is
available free to solution providers whose customers have deployed some of
Citrix’s higher-end technologies.
There are also opportunities for driving new customer business, as well as to
upsell existing customers, Smith says.
