Cloud computing is using the internet to access someone else's software running on someone else's hardware in someone else's data center. This paper explores the architecture of cloud computing and presents a new technology in which cloud computing has a software in the form of bloom. Bloom is a programming language which has received a great deal of attention following its implementation in Hadoop. Hadoop is a platform for this language. Apache Hadoop is a software framework (platform) that enables a distributed manipulation of vast amount of data. This paper also describe the architecture Hadoop and various scheduling follows by it.Keywords

In this paper a parallel and series communication network model with dynamic bandwidth allocation is developed and analyzed. In order to reduce congestion in buffer and to improve voice quality several congestion control methods like bit dropping,selective packet discarding, flow control etc., are developed and successfully implemented. to have an efficient utilization we propose dynamic allocation of bandwidth i.e. the transmission rate of the data/voice packet dependent on the content of the buffer just before it get transmitted. The end to-end performance of the model is measured by approximating the arrival and service processes of the packets follow poisson process. The transient analysis of the communication network shows that dynamic allocation has a significant effect in reducing mean delays and improving throughput of the transmitter. Graphs illustrate performance of the network model for different parameters.
