Zeus Traffic Manager: Deploying Microsoft Intelligent Application Gateway
| Technical Notes |
|---|
Microsoft IAG is a comprehensive, secure remote access gateway that provides secure socket layer (SSL)-based application access and protection with endpoint security management.
Why manage your network traffic using Zeus Traffic Manager?
- Improved Availability: Zeus Traffic Manager is able to make your Microsoft IAG deployment more reliable and available, reducing downtime due to routine maintenance and unanticipated failures.
- Better performance: The unique application acceleration features will improve the end-user performance of Microsoft IAG, and increase its capacity, giving you a much better return on your software and infrastructure investment.
- More secure: Acting as a ‘gatekeeper’, Zeus Traffic Manager delivers improved security as a line of defence for Microsoft IAG, protecting against flash floods and inspecting and filtering all incoming and outgoing traffic.
- Simplified management: Complete traffic inspection and a powerful configuration language let you build sophisticated traffic management policies to manage traffic across large clusters, reduce operational costs and build an efficient, flexible and highly scalable application infrastructure.
In more detail
Reliability
Zeus Traffic Manager provides a single point-of-entry to a cluster of Microsoft IAG servers. With a combination of passive and active health monitoring and performance measurements, Zeus software can route incoming requests to the fastest-responding servers and avoid servers that are failed or underperforming.
Request rate shaping ensures that your Microsoft IAG servers can never be overloaded with requests, and advanced Session Persistence reliably pins users' sessions to individual servers for maximum reliability.
Acceleration
Zeus Traffic Manager's Application Acceleration capabilities improve the end-user experience and increase the capacity of your Microsoft IAG servers to handle transactions. Indirectly, it also increases their resistance to denial of service attacks and reduces downtime due to flash floods and unexpected high traffic volumes.
Zeus Traffic Manager improves application performance by:
- Reducing the number of concurrent connections and transactions the Microsoft IAG server must handle (when decrypting SSL traffic and processing HTTP data), using a combination of network optimizations: low-level TCP offload, TCP acceleration, HTTP connection multiplexing and HTTP connection reuse. Zeus software changes the environment that the Microsoft IAG server operates in, from large numbers of slow, remote clients to a very small number of fast local ones.
- Reducing the total number of transactions the Microsoft IAG server processes by sophisticated context-sensitive content caching.
- Offloading compute-intensive tasks such as SSL decryption, content compression and XML processing onto Zeus software’s high performance software engines.
- Utilizing performance-sensitive load balancing, routing each transaction to the Microsoft IAG server best suited to handle it (based on cache history, current server performance and current server workload).
Security
Total server isolation, request and response scrubbing, request validation and request rate shaping help to place your Microsoft IAG servers in as secure an environment as possible, protecting them from direct attacks from internet clients, invalid or malformed HTTP requests and malicious or incidental flash floods that would severely impact the levels of service you provide.
Management
Zeus Traffic Manager's advanced request routing and manipulation, driven by a fully programmable TrafficScript rules engine, gives you full flexibility to manage both your network traffic and server resources.
Connection draining makes application upgrades a snap. You can safely take a Microsoft IAG server out of service without interrupting any ongoing transactions or sessions for routine maintenance or redeployment.
