Leading Online Travel Site Enhances Performance and Scalability of Java Applications with Oracle Coherence
Redwood Shores, CA – December 16, 2008
Hotwire.com®, a leading discount travel Web site, is using Oracle Coherence, a component of Oracle Fusion Middleware, to support the 24x7, Extreme Transaction Processing (XTP) demands of its Web site.
As its customer base and search volumes increased, the Hotwire.com application infrastructure needed a more scalable solution to support its continued growth.
In less than a month, Hotwire.com upgraded its application infrastructure. They are now able to support millions of customers performing several hundred thousand searches a day while maintaining optimum performance during peak traffic periods.
After evaluating multiple alternatives and performing extensive testing, Hotwire.com chose to implement Oracle Coherence Grid Edition and other Oracle Fusion Middleware components including Oracle WebLogic Server and Oracle TopLink to provide a more efficient, scalable and responsive application infrastructure.
Oracle Coherence is the leading distributed in-memory data grid solution.
Hotwire.com relies on Oracle Coherence to provide the in-memory performance and distributed caching capabilities that help alleviate bottlenecks, reduce data contention and improve Java application responsiveness.
By automatically and dynamically partitioning data in memory across multiple servers, Oracle Coherence enables continuous data availability and transactional integrity, even in the event of a server failure.
Oracle Coherence also allows Hotwire.com to scale linearly and dynamically for more predictable performance and improved resource utilization.
For example, Oracle Coherence allows Hotwire.com to keep frequently accessed data—such as specific deals customers are investigating that were advertised in the site’s weekly newsletter—in memory and closer to applications, reducing network traffic and database loads, resulting in better overall performance across the entire stack.
Additionally, Oracle Coherence helps ensure Hotwire.com remains at peak performance around the clock by automatically and transparently failing over and redistributing cached data across the grid, when a server becomes inoperable or is disconnected from the network.
Oracle TopLink and Oracle WebLogic Server, further enhance the efficiency, scalability, availability and total performance of the new Hotwire.com application infrastructure.
"As our business continues to grow, it is imperative that we have the infrastructure in place to support the growing volume of traffic as more and more customers come to our site to find low prices on travel,” said Eric Grosse, President of the Hotwire Group. “With Oracle Coherence and Oracle WebLogic Server as the backbone of our infrastructure, we can now efficiently manage the transaction processing requirements of our business, while enhancing the user experience and results for our customers.”
“Online travel is a classic example of an industry that grew faster than the technology supporting it,” said Cameron Purdy, vice president of development, Oracle. “By deploying an in-memory data grid and an industrial-strength application server on commodity hardware, companies like Hotwire.com are addressing their XTP requirements while supporting business and customer loyalty goals.”
