I dread merging traffic signs. We all know what happens when the road we’re merging with another road: traffic congestion. It’s logical, right? When 30 cars on one road converge with 50 cars from another, a backup is eminent. (The 101 and 280 interchange in the Bay Area is a perfect example.)
Network traffic experiences a similar effect when two or more data centers consolidate into one, or when enterprises add more centralized applications for branch offices to fan into, or an enterprise business grows with more remote employees accessing the centralized apps. The result is users complaining to IT about slow application performance and unreliable access to applications.
Virtualization has enabled many large IT organizations to eliminate data centers and consolidate the IT infrastructure into fewer physical locations. This has helped save companies in deployment, cooling, power, maintenance, and support costs. But it’s not all rosy, and does come at a cost. Consolidating infrastructure imposes an even greater strain on the wide area network (WAN) as more applications become centralized and delivered to remote locations. Inevitably, this leads to poor network performance and slow response times. So, while some problems are solved, new problems arise that adversely impact user productivity, business communications and commerce.
Data center-class WAN optimization solves these challenges by applying advanced network-based optimization techniques that include deduplication, packet order correction and traffic shaping to control and optimize application performance. Data center-class WAN optimization enables today’s enterprises to squeeze more traffic onto the network to provide the most cost-effective use of available bandwidth. This allows organizations that are consolidating their data centers to support more users and deliver more applications—without adding costly bandwidth.
If you are in the process of, or are currently consolidating, your data centers, keep in mind the new challenges you will face by merging users, applications and data into fewer data centers and across the same wide area network. Avoid network congestion and minimize user “road rage” by deploying data center class WAN optimization. You and your users will be glad you did.
