Data Center Protections
Data Center Protections
One significant trend that has emerged during the current business/economic cycle
is that IT projects that reduce cost are winners. This savings trend is as strong as I
have experienced in my twenty-five years within the IT industry. In particular, it’s propelling data center
consolidation, server virtualization and mobile computing projects. As enterprises consolidate data
centers and miniaturize them with virtualization, cloud-computing providers are busy offering a new
lower cost IT delivery economic model. In short, a new tier of computing has emerged were endpoint
devices are mobile and applications are delivered via corporate data centers and cloud computing
facilities. This new model of computing that also increases convenience and productivity is lacking in one
important area; network security for both mobile endpoints and the ability of data center security
appliances to keep up with application demand.

And keeping up with application demand is one of the most challenging tasks IT business leaders are
encountering. Not only has information demand skyrocketed during this business cycle but content in
the form of web pages has become dynamic, where a single page request opens a multitude of
connections pulling content from various sources to satisfy user expectations of real time information
access. For example, a single web page request can easily spawn more than fifty network connections
over physical and virtual infrastructure placing extraordinary demands on network speed, latency,
reliability and security. For the uninitiated, just point your browser to any of these sites—disney.com,
cnn.com, nytimes.com, et al—and notice rich content in action. As the page is presented, it serves up
video, photos, audio, rich text and more, all of which are pulled from various sources within a data
center fabric over virtual and physical infrastructure. The calculus IT leaders are seeking to solve
includes massive growth in information demand plus Brownian motion traffic flows, thanks to dynamic
content plus densely packed data centers, thanks to virtualization. Even with consolidation and
virtualization information/application, demand is forcing the overall data center market size to expand
from 108 million sq. ft. in 2009 to a projected 117 million sq. ft. by year end 2010, according to Frost &
Sullivan. Part of the solution to IT leaders’ calculus problem is found in a data center network fabric that
supports millions of connections/session of east-west and north-south traffic flows securely.

To put the mobility trend into perspective, Apple sold over 3.3 million iPads in its first 3 months; the
highest uptake of any endpoint device. Google activates 100,000 Android-based phones per day. Cisco
recently announced its CIUS android-based table for business use with tight links to its unified
communications (UC) and videoconference systems. Every major UC provider will be offering similar
devices while traditional computer vendors serve up android-based tablets over the next few quarters.
The iPad and Android tablet is a new tier of computing, which are driving users to access applications
over mobile and wireless networks in addition to their wired and VPN networks.
