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.


Transactions for XTP

Forget about app servers or heavy platforms: this whitepaper outlines our main vision for lean & extreme transaction processing. Also: what's a transaction manager anyway, and why do you need one?

Transactions for SOA

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.
