For software development teams working on transactions-based projects such as e-Trading applications, who are dissatisfied with heavy weight platforms, Atomikos ExtremeTransactions® is a lean, light-weight transaction management library for atomicity. Unlike legacy JEE app servers or ESBs, we enable JEE without the application server, SOA without ESB and transactions, and provide light-weight BPM for REST enabling developers to pick and compose their own optimal technology stack.
