Introduction:
The Hybrid Enterprise
Where is the best place to deploy enterprise applications? In your data center or in the
cloud? This choice, which IT leaders are facing on a daily basis, can be a key driver for
business success.
For most enterprises, the answer to which deployment is that “it depends.” Some
applications, such as proprietary business-critical applications, may fit better within
your data center. Others, such as sales apps, are best run from the cloud. In fact, a 2015
survey commissioned by RightScale, shows that 93% of respondents are using some
form of cloud whether it be public, private, or hybrid for one or more applications.1
The same is true for networks. Private MPLS links are expensive but highly reliable and
predictable. The public Internet is less reliable and less predictable, but also much less
expensive in terms of bandwidth costs. Which option is best depends on your application
and business-specific needs. This is reflected in a study from Nemertes Research2
showing most enterprises mix both MPLS and public Internet links.

Architecting for Application Performance in the Hybrid Enterprise • Introduction
Introduction:
The Hybrid Enterprise
That is why most enterprises today employ a mix and match strategy:
Deploy your most mission-critical apps to the data center and provide
access to them via more expensive, but highly reliable and predictable
MPLS links. Deploy your other apps to the cloud (often SaaS) and provide
access via inexpensive public Internet.
The result is a complex mesh of on-premises and cloud applications
connected by both MPLS and public networks. Enterprises have rejected
the either/or mentality for a best-for-the-task-at-hand strategy. Essentially,
enterprises find themselves in an era of the hybrid enterprise, where
hybrid clouds and hybrid networks have become the norm. It is a strategy
with many advantages, but one that presents unique challenges as well.
