In order to minimize failure impact on the system and application execution, failures should be anticipated and handle. Fault tolerance techniques are used to predict these failures and take an appropriate action before or after failures occur. | ISSN:2249-5789 Prasad Saikia et al , International Journal of Computer Science & Communication Networks,Vol 4(1),01-08 FAULT TOLEREANE TECHNIQUES AND ALGORITHMS IN CLOUD COMPUTING Dr. Lakshmi Prasad Saikia Professor & Head, Dept. of Computer Sc. & Engineering Assam down town University, Guwahati, India Email: lp_saikia@ Abstract Yumnam Langlen Devi B.

Cloud computing emerges as a new Cloud computing provide many service to the user. Now a day the user level is highly increased to utilize the services in cloud computing. In cloud computing the major problem area is fault tolerance. Fault tolerance is a major concern to guarantee availability and reliability of critical services as well as application execution. In order to minimize failure impact on the system and application execution, failures should be anticipated and handle. Fault tolerance techniques are used to predict these failures and take an appropriate action before or after failures occur. computing paradigm which aims to provide reliable, and quality of service guaranteed computing lively environments for end-users. The increasing demand for flexibility in obtaining and releasing computing resources in a cost-effective manner has resulted in a wide adoption of the Cloud computing paradigm. Fault tolerance computing is one that can continue to correctly perform its task in the presence of hardware failures and/or software or to operate 1. INTRODUCTION satisfactorily in the presence of faults. Fault tolerance Cloud computing is sharing of resources on a bear-on with all the inevitably techniques to enable larger scale which is cost effective and location robustness and dependability .The main benefits of independent. Resources on the cloud can be deployed implementing fault tolerance in .
