dotCloud is a new kind of PaaS designed for the FullStack Development enabling developers to build, deploy and scale applications in the cloud using virtually any combination of language and database without the need for additional hardware or software.

The San Francisco-based company announced today the immediate availability of support for WebSockets, MongoDB 2.0 and vertical scaling. Continuing to support application development from front to back, the support for new technologies speak to the impact of HTML5 and the rise of the FullStack Developer.

Continuing to pave the way in the PaaS space, new technology support on the dotCloud platform includes:

• Websockets support – All dotCloud applications can now leverage websockets for real-time, bi-directional communication between the browser and the backend. With websockets, developers can now build rich, real-time interaction into their application.

• MongoDB 2.0 – a major update to our leading high-availability database service – with guaranteed backwards compatibility. When MongoDB 2.0 was released, our database team determined that the upgrade was reverse-incompatible for some of our users, and decided to wait until the upgrade was seamless.

• Vertical Scaling – dotCloud becomes the first PaaS to support both horizontal and vertical scaling. To scale their application, developers can choose between increasing concurrency (horizontal), larger memory allocation (vertical), or both.

“We believe there is a fundamental shift happening in the application development space where languages and databases are agnostic and sets services can be leveraged to build products from beginning to end,” said Solomon Hykes  “This is FullStack development and we are focused on delivering that promise.”

dotCloud is funded by Benchmark Capital and Trinity Ventures. The company was founded by Solomon Hykes and Sebastien Pahl in 2010.
