Software as a Service (SaaS) is one of the delivery model of cloud computing in which service are provided by the service providers and client make use of it through Internet.Here we present a saas in pcloud.pcloud is a distributed system which contains a number of cooperated nodes.In pcloud, distribute the programming software to a number of nodes so that queries can be executed in parallel manner.In this distributed system, communication overhead between the co-operated nodes is very low.Programming code is send as a user queries to pcloud where it is processed and retrieved through PIR protocol.The concept used by the PIR protocol is the way that accesses of sequential segments are made to different physical storage devices.To minimize the effect of node failures, pCloud includes data replication.The Load Balancing can be achieved by loosely coupled and nearest neighbor property of clouds.
