Brocade Virtual ADX Supported Features
The Brocade Virtual ADX supports all of the essential features for ensuring the optimized delivery of
application traffic.
Load Balancing
The Brocade Virtual ADX enables the efficient distribution of traffic among application and
infrastructure servers. In this capacity, the system can load balance traffic based on a number of
different characteristics including server connection load, server resources such as CPU and
memory, application response time, and pre-assigned server weights while ensuring session
stickiness on selected servers when required. Together, these capabilities combined with a rich set
of server monitoring capabilities serve to ensure an optimal application experience.
Content Switching
To manage traffic based on deeper application intelligence, the Brocade Virtual ADX can determine
the server that is best suited to respond to different traffic types and direct traffic accordingly.
Traffic policies can be configured based on both URL and HTTP header information allowing traffic
to be distributed based on user information and device characteristics as well as the content
they're requesting.
OpenScript
The Brocade Virtual ADX includes a powerful application scripting engine for developing real-time
application services - allowing for the manipulation of transaction responses based on information
in the request and vice versa enabling more advanced traffic-handling. The small footprint of the
OpenScript engine increases the number of scripts that can run simultaneously on the system. And
to ensure optimal performance, the system can estimate the performance of custom scripts
without requiring the need for live traffic.
SSL offload for optimization of encrypted traffic
The Brocade Virtual ADX supports the offloading of CPU-intensive SSL negotiation and connection
management from application servers, to improve response times. This is achieved by decrypting
incoming client requests, processing the traffic and load balancing each request before
re-encrypting the response on the return path.
