The most cost effective way to scale SOA

While Service Oriented Architecture (SOA) may not be the buzzword it used to be, the use of web services is exploding due to the additional demand of Cloud, mobile, and partner integrations. Traffic volume, the number and variety of clients, and the types of transactions are all increasing, requiring SOA and application infrastructures to scale to meet demand. Vordel XML Accelerator offloads CPU intensive tasks from application server and enterprise service bus (ESB), making it the most cost effective way to scale SOA and application infrastructure.

XML processing and security tasks such as signing and encryption are very CPU intensive tasks for the application server and ESB. Vordel XML Accelerator is a purpose-built technology that handles these tasks with extreme high efficiency. Adding the Accelerator frees up the CPU cycles from existing application infrastructure in a way that is more cost effective than simply adding more application and database servers.

Offloading XML Processing and Security Tasks

XML offers extreme flexbility and extensibiltiy, along with extensive security provisions, making it the key enabling technology for SOA. However, this flexibility and security comes at a cost. XML processing and security tasks (e.g. signing and encryption) can consume disporpotional amount of application and database server resources in very inefficient ways.

Vordel XML Accelerator offloads these tasks to an ultra efficient, purpose-built engine:

• XML parsing
• XML schema validation
• Protocol translation
• Message transformation
• Signing
• Encryption and decryption
• Hardware security module (HSM) integration
• SSL termination and operations

Purpose Built XML and Security Engine

Vordel XML Accelerator is powered by Vordel's patented high performance VXA Engine. The VXA engine accelerates policy driven processing of all common XML formats, including POX (Plain Old XML), SOAP, REST, and AJAX. The VXA Engine is a software program written in native code, delivering wire speed performance without any proprietary hardware or add-on accelerator cards. The use of native code allows Vordel to optimize low-level processes to squeeze every ounce of performance out of the system, and deliver the same high performance across all form factors, including software and appliance, on-premise and in the Cloud. Independent third-party testing has proven that Vordel's gateway delivers the same wire-speed performce as hardware based solutions and is 15 times faster than other software based solutions.

More Options to Add Speed and Scale

In addition to offloading CPU intensive tasks, Vordel XML Accelerator can further improve system throughput and performance by optimizing flow of traffic. It is common to have simple lookup services that have relatively static responses but are used in high frequency. The Accelerator can cache these responses to reduce the number of requests hitting backend services. If certain services have unusually heavy procesing needs or are used heavily, the Accelerator can route requests to different servers to prevent a few slow services from causing general system-wide poor performance across all services. Additionally, the Accelerator can throttle traffic by service to smoothout load and prioritize processing
