New WSO2 Case Study Describes How eBay Uses Open Source WSO2 ESB to Process Over 1 Billion Transactions Per Day

Palo Alto, CA – July 27, 2011 – WSO2 announced today that it has published a new case study about eBay and how the world’s largest online marketplace is using several WSO2 Enterprise Service Bus (WSO2 ESB) instances to process more than 1 billion transactions per day. The open source WSO2 ESB manages mediation and orchestration within the eBay service-oriented architecture (SOA). Currently the WSO2 ESB instances handle all external traffic loads from different functional areas, such as shopping, trading, checkout, and mobile, among others—supporting some $2,000 worth of transactions every second.

It is strong validation of the lean open source, open standards approach to our WSO2 ESB and to the SOA expertise of our service and support team.”
