Applying Application Delivery Technology to Web Services
Overview
The Cisco
®
ACE XML Gateway is the newest technology in the Cisco application network services
products. This document explains how to take advantage of the integrated functions of the Cisco
ACE Application Switch and Cisco ACE XML Gateway to maximize availability, performance, and
security of SOAP and XML (Extensible Markup Language) web services.
Challenge
As enterprises continue to migrate to service-oriented architectures based on web services, a
major challenge is making sure that those services are highly available, meet performance
requirements, and are secure from threats at the XML level. Because web services are deep in the
network stack, addressing this challenge requires a solution that is fluent in XML and SOAP and
that is also highly available and provides optimized HTTP-based application access. The wide
variety of technologies used to implement web services compound this challenge, making
coordination of security policies across the enterprise difficult. In addition, XML requires more
processing power to implement security than other, lower-level protocols do. These challenges
make an exclusively software solution impractical and mandate a network infrastructure solution.
Business Benefits
By using a Cisco ACE Application Switch, either the Cisco ACE Module or the Cisco ACE 4710
Appliance, for Layer 4 to 7 load balancing and optimization and a Cisco ACE XML Gateway for
XML processing within the Layer 7 payload, you can achieve the following benefits:
●
Accelerate and optimize access to web services applications: The Cisco ACE Application
Switch plus Cisco ACE XML Gateway solution enables acceleration features such as
Secure Sockets Layer (SSL) offload, HTTP 1.1 session reuse and multiplexing, and XML
transformation and schema validation.
●
Secure access to web services applications: The solution combines the TCP/IP
normalization and HTTP RFC compliance functions of Cisco ACE with the industry-leading
XML threat-defense capabilities of the Cisco ACE XML Gateway to provide protection from
attacks at all levels of the network stack, Layers 4 to 7 and above.
●
One-source solution for XML acceleration, availability, and security needs: Cisco is the only
vendor that provides a complete solution.
●
Use of your Cisco ACE investment to meet your web application, web services, and other
network protocol needs: Virtualization in the Cisco ACE helps ensure that denial-of-service
(DoS) attacks or traffic storms in browser-based applications do not affect your mission-
critical web services, without requiring you to invest in separate infrastructure.
