Through the 1990s to 2012 the internet changed the world of computing drastically. It started its journey with parallel computing after it advanced to distributed computing and further to grid computing. And in present scenario it creates a new world which is pronounced as a Cloud Computing [1]. These all three terms have different meanings. Cloud computing is based on backward computing scheme...

Through the 1990s to 2012 the internet changed the world of computing drastically. It started its journey with parallel computing after it advanced to distributed computing and further to grid computing.

Infrastructure as a Service (IaaS) is a rapidly expanding model of cloud computing. It includes control of computing resources, such as memory, computing power and storage capacity, satisfying the most fundamental IT needs for businesses on a usage-based payment model. Currently, there is an increased demand for IaaS services, which in turn feeds competition among cloud providers. As the price ...

In the Infrastructure-as-a-Service cloud computing model, virtualized computing resources in the form of virtual machines are provided over the Internet. A user can rent an arbitrary number of computing resources to meet their requirements, making cloud computing an attractive choice for executing real-time tasks. Economical task allocation and scheduling on a set of leased virtual machines is ...

Cloud computing becomes very popular these days and fault tolerance is a major issue in this cloud environment. This paper is dedicated to study different kinds of faults and various techniques for handling them. This survey mainly focuses on why fault tolerance is required in cloud computing and which techniques are used to handle these failures so that services can be delivered without delay ...

Processing large volumes of Linked Data requires sophisticated methods and tools. In the recent years we have mainly focused on systems based on relational databases and bespoke systems for Linked Data processing. Cloud computing offerings such as SimpleDB or BigQuery, and cloud-enabled NoSQL systems including Cassandra or CouchDB as well as frameworks such as Hadoop offer appealing alternative...

In recent years Cloud Computing has seen a lot of improvement in terms of security, stability and maturity thus it should be able to meet the demands and requirements of critical infrastructures and well-regulated areas. This paper focuses on a secure and modular approach for a cloud infrastructure that conforms to the Measuring Instrument Directive of the European Union while preserving the ad...

Cloud computing usage has increased rapidly in many companies. Cloud computing offers many benefits in terms of low cost and accessibility of data. Ensuring the security of cloud computing plays a major role in the cloud computing, as customers often store important information with cloud storage providers but these providers may be unsafe. Customers are wondering about attacks on the integrity...

As we know that now a days the use of computing services is rapidly increasing over internet, so there is a need to buy mainframe system for every enterprise to full fill the requirements of end users and this can be overcome by use of cloud computing services in a inexpensive manner. Cloud computing paradigm offers a wide range of computing services for enterprises in terms of elasticity, serv...
