We are happy to announce the launch of our latest open source product: COMSAT. Parallel Universe now provides a complete server-side stack, with Comsat at the web layer, Quasar for the application logic, and Galaxy for clustering and fault tolerance. SpaceBase, along with a future highly-concurrent non-spatial database called Dark Matter, form the database layer. This stack helps you write performant, highly scalable, and fault tolerant software, that takes full advantage of modern multi-core hardware, while at the same time emphasizes a simple programming model.
