The Infrastructure as a Service (IaaS) cloud computing model is widely used in current IT industry, providing the cloud users virtual machines as the executing environment. However, current executing environment the cloud provided is not trustworthy. For a user’s executing environment faces threats from malicious cloud users who aim at attacking the underlying virtualization software (virtual m...

Cloud computing has grown from being a promising business concept to one of the fastest growing segments of the IT industry. So, cloud environment always remains vulnerable to attacks. The framework serves as an excellent platform for making cloud services intrusion tolerant. The feasibility of the framework has been tested by making cloud’s Infrastructure as a Service (IaaS) and Data Storage S...

Next generation Cloud applications present elastic features and rapidly scale their comprised resources. Consequently, managing and monitoring Cloud applications is becoming a challenge. This paper showcases the functionality and novel features of: (i) c-Eclipse, a framework for describing Cloud applications along with their elasticity requirements and deploying them on any IaaS provider; and (...

The banking sector is one of the best examples who create Big Data with increasing transactions per second across the globe. Each bank is administered by the DBA (Database Administrator) as a technical in charge. DBA makes an arrangement in the branch to divert query from authorized user to the appropriate data repository. The SQL core Engine accepts input stream, processes and optimized to inc...

Customers of cloud services choose the VMs profiles (SLAs) offered by the provider, and pay according to how long these VMs are utilized. Many works deal with how to decrease the cost of VM requests scheduling, but consider solely the charging models in the SLA. However, other characteristics in the SLA must be taken into account when choosing a VM to execute users’ applications (e.g. processin...

Future Internet applications are becoming increasingly dynamic and can be composed of a wide range of services controlled and hosted by di erent stakeholders. This paper addresses the challenge of resource provisioning for applications that have speci c Quality of Service (QoS) requirements and where consumers of Cloud resources want to avoid lock-in to any speci c Infrastructure-as-a-Service (...

Cloud computing is transforming the software landscape. Software services are increasingly designed in modular and decoupled fashion that communicate over a network and are deployed on the Cloud. Cloud offers three service models namely Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Softwareas-a-Service (SaaS). Although this allows better management of resources, the Qual...

Smartphones have become popular in recent days due to the accessibility of a wide range of applications. These sophisticated applications demand more computing resources in a resource constraint smartphone. Cloud computing is the motivating factor for the progress of these applications. The emerging mobile cloud computing introduces a new architecture to offload smartphone and utilize cloud com...

Spot instances are commonly offered by IaaS cloud providers to opportunistically utilize spare capacity and meet temporary user demand for additional resources. Although the availability of service SLAs is a core paradigm of cloud computing, spot instances in practice still come without any service quality guarantees. We aim to extend the spot instance service to provide a probabilistic SLA for...
