Company: GDSX, Ltd.
Application: Reservation data processing services for travel industry
Server Configuration: Back-end application servers, front-end Terminal Servers, and 3 node StateServer cluster
Reason For Deployment: To ensure real time synchronization of critical data for application servers, without sacrificing performance.
Results: Application servers instantly have necessary data to run distributed applications and are synchronized.
Background
GDSX supplies software and services to corporate clients in the travel industry. Customer data is pulled from proprietary third-party vendors and is processed through various customer-specified workflows by an application server farm. The data that is waiting to be processed must be load balanced based on the resources available to the application servers.
Challenges
To run their applications across the server farm, GDSX needed to find a way to ensure that certain state information for load balancing was always in sync and updated in real-time for every application server in the farm. They investigated database solutions, but determined that they were too slow to meet the needs of their applications, and to make them highly available they would have to be clustered; a very expensive solution. They also needed a high-performance way to ensure that each application server could process data from any customer, while guaranteeing that each customer would only be processed by one server at a time. That’s when they discovered ScaleOut StateServer and decided to use distributed caching to maintain the critical data in memory.
Results
“ScaleOut StateServer was very easy to install and configure and it runs with essentially zero management attention.”
–Chris Kolb, Manager IT and Databases for GDSX
Deployment Details
GDSX has deployed ScaleOut StateServer as a distributed cache on three application servers that are connected to terminal servers and web servers on the front-end. The front-end servers are running ScaleOut Remote Client which provides GDSX’s client applications with a highly available link to the distributed cache.
The application servers have 2GB of memory each and are connected via a fast ethernet network. The load balanced web tier connects to the application tier via a fast ethernet network.
Based on the success of using distributed caching, GDSX has plans to expand its use of ScaleOut StateServer to cache other data in memory for faster overall performance.
