Every business needs high availability and resilience against the faults. Fault tolerance is an approach to tolerate and avoid faults and errors in the system after its development and implementation. This work is presenting, detailed discussion, about the types of faults and various types of fault tolerance techniques and comparison of various fault tolerance models. This paper is indented to develop a comparative analysis of fault tolerance models so that advantages of the models can be leveraged and also highlight the shortcomings of the available models, can be extended for further research in the field of cloud computing. Keywords— Cloud computing, fault tolerance, failures, proactive, reactive, adaptive

It is a model for empowering omnipresent, on-request access to a common pool of configurable registering resource (e.g., computer networks, servers, stockpiling, applications and servers, storage, applications and services), which can be quickly provisioned and discharged with negligible administration exertion. Cloud computing may be a virtualized surroundings which gives administrations similarly as Virtual machine (VM) instances. These VM instances are dissimilar. Cloud clients might pick which setup alternately sum about instances they need, Concerning illustration there would numerous resources available. There might make a few circumstances which prompt underutilization about these resources. So, a proper resource allocation technique has to be done to increase the revenue of the cloud provided. Resource Provisioning means the selection, deployment, and run-time management of software (e.g., database server management systems, load balancers) and hardware resources (e.g., CPU, storage, and network) for ensuring guaranteed performance for applications. Resource Provisioning is an important and challenging problem in the large-scale distributed systems such as Cloud computing environments.

In the cloud environments, data availability and backup replication are critical and complex issues in the an efficient fault tolerance policy is the major. Fault tolerance policy is the strategy in action when a fault occurs in the system. Taking backups is the one of the most usual solution of keeping the data safe out of these faulty conditions, But sometimes traditional schemes and backup servers might get into bottleneck conditions due to their replica management schemes. CSP has to adopt a fault tolerance policy to ensure continues delivery of services. There are two main categories policies that are proactive and reactive fault tolerance, both have different advantages in different situations. Our research introduces a new approach as a fault tolerance policy, which is having characteristics of both the above mentioned policies. In our approach re...

It provides a way to adopt information Technology and its features without huge expenditure on infrastructure and applications. Cloud computing provides multiple on-demand services accessible from a broad network with the ease of scalability even in shared environment so to achieve cost effectiveness. However, despite the potential gains of cloud computing still lack in providing 100 % up-time and ensured data availability to the business organizations.These issues may be very critical for business process that they might even lose data. Taking this problem we tried to give a reliability and availability based fault tolerance approach based on replica distribution in previous work [14], In this work we are trying to evaluate the process by implementing the scheme and get the statistical performance analysis of the approach. In th...

Users can allocate and de-allocate the services of the cloud. Cloud uses virtual machines to offer assistance. Availably, rapid elasticity and Cost-effectiveness is main key benefits of cloud technology. As today is the digital world, user's uses cloud technology to perform ethical and unethical work. To identify any crime or unethical work in cloud environment forensic team allocated. The Cloud forensic team follows a complete forensic process in a cloud environment to identify any attack and the person behind this attack. Cloud Forensic process completed in four steps that are Identification, Preservation and collection, Examination and presentation. When the user performs single activity in the cloud, it stored in the form of log files. Logs are crucial assets in the legal process. These cloud log files can track all the user's actions. The integrity of log ...

It provides a way to adopt information Technology and its features without huge expenditure on infrastructure and applications. Cloud computing provides multiple on-demand services accessible from a broad network with the ease of scalability even in shared environment so to achieve cost effectiveness. However, despite the potential gains of cloud computing, security of an open access and shared environment is still a question mark, which directly impact cloud adoptions. Deploying data and business applications to a third party, security and privacy becomes critical concerns. Cloud computing is going to serve enterprise needs for confidentiality of the customer data and compliance, service providers have to provide intense security to ensure sensitive enterprise applications. In this paper, we surveyed a detailed analysis of the sec...
