WAN optimisation key to maximizing your cloud investment

Alan Leong, Vice President, APAC at Silver Peak | May 2, 2014
Organisations need to optimise the WAN, which has the ability to reduce over 90 percent of the traffic across the network and provide the scalability needed to support all current and emerging applications.

WAN optimisation is essential for the migration of large volumes of data, and ensures that the data is easily and rapidly available. Essentially, all three network challenges (bandwidth, latency caused by distance and poor network quality caused by packet loss) need to be addressed to optimize replication throughput across a WAN, which will help guarantee successful cloud storage while maximizing RPOs.

Three techniques for three network challenges

Three real-time optimisation techniques can address the three network challenges. Latency mitigation using various protocol acceleration techniques to overcome the impact of distance, forward error correction (FEC) and packet-order correction (POC) overcome packet delivery issues in real-time, while quality of service (QoS) enables enterprises to prioritize key traffic. Prioritizing traffic ensures allocation of necessary resources, and deduplication and compression maximize bandwidth utilization. By deduplicating traffic at the IP network layer, any enterprise application is made more efficient. The investment made to improve cloud storage can be amortized across other enterprise applications.  More data can ultimately be accessed and transferred between the cloud and the user in less time - making it even easier for organisations to enjoy the benefits storing data in the cloud has to offer.

Take full advantage of your cloud investment

As organisations invest in cloud storage initiatives, optimizing the WAN has become crucial, and now more than ever, organisations must make sure their investment does not lose value over time.  Stabilizing the network needs to be top of the agenda.  By providing 20-times faster movement of data and reducing redundant data transmission by more than 50 percent, WAN optimisation technology will allow companies to meet their RPOs and deliver any cloud application.
