Major Enterprises are transitioning toward ‘Service Oriented Architectures’ to improve the flexibility of their business critical applications. SOA’s (or “Web Services”) allow developers to create re-usable code that can be accessed as network-available functions.
Web applications communicate using a protocol called SOAP, which is based on XML. SOAP and XML are verbose text-based protocols, which means that an application re-engineered as a Web Service will often consume 4-10 times more network bandwidth than it did previously. For example, SAP® NetWeaver, the Web Services version of SAP’s flagship application, creates more than 4 times the network traffic as the original version.
WAN performance can delay the deployment of Web services. All too often, enterprises spend significant time and effort fine tuning their Web applications to run better across wide geographic areas, or they are required to purchase additional Web servers or upgrade WAN bandwidth to make application delivery work across a distributed enterprise.
Silver Peak: The Keystone to Successfully Deploying Web Services
Silver Peak NX series appliances leverage a variety of optimizations techniques to accelerate and secure SOAP and XML, ensuring successful SOA rollout in shortened periods of time. This includes:
Network Memory and Silver Peak’s advanced compression techniques eliminate as much as 99% of Web Services traffic across the WAN, increasing network utilization and dramatically improving application response time.
Various TCP Acceleration methods, such as window scaling, selective ACK and fast re-transmit, all improve the performance of Web Services over the WAN.
Forward Error Correction (“FEC”)protects Web traffic from network congestion, which often leads to packet loss. This is essential as Web Services are deployed over IP VPNs or MPLS networks that display high loss characteristics. The result is less ‘service brownouts’ throughout the day when running Web Services.
