Time to rethink your approach to WAN?

Cloud computing and mobility have changed the way we work. They have also changed the way we connect to our enterprise networks.
A Multiprotocol Label Switching (MPLS) WAN service that connects branch offices to datacentres is no longer enough to meet the needs of end users. The internet is fast becoming a core method of connectivity. People want to use the same applications they have on their PCs but on the go via laptops, smartphones and tablets.
Often the result is a complex web of WAN connectivity to cover each situation as it emerges. Whether that is internet used to offload MPLS, mobile broadband or public cloud services. This ad hoc approach leaves the enterprise with multiple point solutions. These are difficult to manage and can undermine application performance for users.
Since MPLS and internet connectivity are both important to smooth business operations, enterprises need to rethink existing connectivity and establish a unified WAN.
But before embarking on a hybrid approach, there are three areas for network planners to consider:
1) Establish interconnections closer to users and to the applications. This reduces end-to-end latency and improves the user experience.
2) Identify the path with the lowest latency. This provides the best network performance between users and applications. Simulation and load testing can help the discovery process.
3) Collaborate across the IT organisation. This makes it easier to manage traffic as more data flows out of enterprise offices.
Public cloud services, SaaS, and mobility are driving enterprises to rethink how they architect their WANs. Gone are the days when all applications resided in regional data centers and branches only needed a single MPLS connection. Today, applications reside off the corporate network and users connect from wherever they choose to work. This change calls for a new approach for optimizing the corporate WAN and Citrix is at the forefront of this evolution.
