Why Atomikos

Transactions without Appserver

For software development teams who need transactions for their self-contained cloud applications, we offer a lean, light-weight transaction management library. Unlike legacy platforms we enable JEE without the application server, and provide light-weight BPM for REST enabling developers to pick and compose their own optimal technology stack.

Forget about web service transaction 'standards' (WS-*), the enterprise service bus (ESB) or business process management (BPM): this whitepaper introduces TCC, our vision for light-weight transactions in SOA.
