Enhanced Model of Fault Tolerance in Cloud Computing Architectures

Cloud computing has embarked a revolution in accessing, provisioning and consumption of the information and computing in the ICT industry. It has emerged as a novel paradigm of high performance and large-scale computing that actuates relocation of computing and data from desktops and personal computers to big data centres. Cloud computing refers to manipulating, configuring, and accessing the applications online. It offers online data storage, infrastructure and application and involves both a combination of software and hardware- based computing resources delivered as a network service. Cloud computing's rising popularity has led many organizations to adopt it, streamlining business operations, lowering infrastructure costs, and enhancing agility by making application deployment and modifications easier. Cloud computing, like any computer system, is susceptible to failures. These failures are often a significance of the inherently distributed and complex nature of cloud platforms. Cloud computing systems need to be built for failure to ensure that they continue operating even if the cloud system has an error. The errors should be disguised from the cloud users to ensure that users continue accessing the cloud services and this intern leads to cloud consumers gaining confidence in the availability and reliability of cloud services. In this paper, we propose the use of N+1 Segmental redundancy architecture to design and implement failure-free clouds.
