Next-Generation Load Balancing and Application Traffic Management

1 © ZEUS TECHNOLOGY LIMITED 1995-2007 Managing your Application Traffic

Zeus Extensible Traffic Manager (ZXTM) makes your networked and web-enabled applications faster, more reliable, secure and easier to manage.

A high-performance Software Traffic Manager Zeus Extensible Traffic Manager (ZXTM) manages your application traffic, inspecting, transforming and routing requests as it load-balances them across the application infrastructure. The powerful TrafficScript™ engine lets you implement whatever traffic management policies are most appropriate for your enterprise, drawing on the whole range of capabilities of ZXTM.

Application Acceleration ZXTM offloads compute-intensive tasks, and the integrated Content Caching reduces the load on your infrastructure. TCP offload, Traffic buffering, and HTTP optimizations produce the environment for your applications to run at peak performance and capacity. All these add up to dramatic improvements in service throughput and responsiveness, significantly better ROI and an improved customer experience. ZXTM provides you with an intuitive and SSL-secured Web-based user interface Service Reliability Active and Passive Health monitors and continual performance monitoring ensures that client requests are load-balanced across the fastest servers in your infrastructure, ZXTM’s TrafficCluster™ scalability protects against compound failures at all levels.

Application Security Total server isolation, request and response scrubbing, request validation and request rate shaping all protect your application infrastructure from direct attacks, invalid or malformed requests and malicious or incidental flash floods that would otherwise impair the level of service you provide.

Manage your traffic and manage your infrastructure with ZXTM ZXTM gives you full control over how your traffic is managed, and how your application components are used. Reporting and alerting tools, detailed diagnosis, connection draining and a control API make it a valuable addition to your application infrastructure.

ZXTM can be deployed in any number and combination of active and backup units to protect you against compound failures.

Each ZXTM unit monitors the health of all the other units in the traffic management cluster and of the back-end servers.

Incoming traffic is processed by ZXTM.

TrafficScript™ rules are used to inspect and manipulate the request and send it to the correct server pool.

The traffic is distributed across the server pool using the appropriate load balancing algorithm.
