eBay uses 100% open source WSO2 ESB to process more than 1 billion transactions per day

eBay is the world's largest online marketplace. Today, more than 94 million active users around the globe flock to eBay to find the best deals in cyberspace. In 2010 alone, the total value of goods sold on eBay was a staggering $2,000 every second. Along with eBay's success comes a huge demand to ensure reliable, 24x7 availability of the services that enable these transactions. There's no room for error, especially during the peak online holiday shopping season. For eBay, that has meant using WSO2 ESB to carry more than 1 billion transactions per day.

During evaluation, WSO2 ESB outperformed all other ESB options in both speed and reliability.
