摘要：

This paper describes a distributed, scalable, manageable, layered organized SaaS infrastructure. After reviewing SaaS requirements we designed an infrastructure organized in 3 abstracted layers: Presentation, Production, and Storage. The Presentation layer receives requests from customers and distributes them to the Production layer using OSI 4/OSI 7 level load balancing algorithms. The received requests are processed on the Production layer by the application software logic. In order to store information, the software running on the computers on the Production layer uses the Storage layer. On the Storage layer we introduce Zatara, our distributed database implementation that guarantees data redundancy using group replication. Zatara performance scales linearly with the number of computers it runs on. Several benchmarks of Zatara are presented in the paper.
