The use of Cloud Computing has increasedrapidly in many organization .Cloud Computing provides many benefits in terms of low cost and accessibility of data. In addition Cloud Computing was predicted to transform the computing world from using local applications and storage into centralized services provided by organization.[10] Ensuring the security of Cloud Computing is major factor in the Clo...

Amazon’s Elastic Compute Cloud (EC2) Service is one of the leading public cloud service providers and offers many different levels of service. This paper looks into evaluating the memory, central processing unit (CPU), and input/output I/O performance of two different tiers of hardware offered through Amazon’s EC2. Using three distinct types of system benchmarks, the performance of the micro sp...

Cloud computing brings great challenges in the field of data security and security assurance. In this paper, we are analysing the different types of cloud security issues. The key and signature are generated using the elliptic curve cryptography algorithm and Ron Rivest, AdiShamir and Leonard Adlema algorithm to provide efficient security. Dynamic Merkle hash tree is constructed for providing d...

With the adoption of mobile healthcare applications and the success of cloud service models, we propose a privacy management framework for mobile health care applications with support for dynamic privacy management of health data sharing. Our solution extends the XACML policy language by incorporating user access context into the privacy policy rule enforcement. We provide an implementation of ...

Individuals and organizations tend to migrate their data to clouds, especially in a DataBase as a Service (DBaaS) pattern. The major obstacle is the conflict between secrecy and utilization of the relational database to be outsourced. We address this obstacle with a Transparent DataBase (T-DB) system strictly following the unmodified DBaaS framework. A database owner outsources an encrypted dat...

Cloud computing platforms such as Amazon EC2 provide customers with flexible, on demand resources at low cost. However, while existing offerings are useful for providing basic computation and storage resources, they fail to provide the security and network controls that many customers would like. In this work we argue that cloud computing has a great potential to change how enterprises run and ...

Different cloud platforms offer similar services with different characteristics, names, and functionalities. Therefore, describing cloud platform entities in such a way that they can be mapped to each other is critical to enable a smooth migration across platforms. In this paper, we present a DSL that uses a common cloud vocabulary for describing cloud entities covering a wide variety of cloud ...

In the recent years the progress in technology and the increasing availability of fast connections have produced a migration of functionalities in Information Technologies services, from static servers to distributed technologies. This article describes the main tools available on the market to perform Analytics as a Service (AaaS) using a cloud platform. It is also described a use case of IBM ...

In this paper, a novel workflow platform as a service is presented1. The paper describes how existing components of adaptive workflow technology are integrated and extended towards a cloud platform on which individual users as well as small business enterprises may model, execute and adapt workflows without the need to possess an own workflow management system. As the adaptive workflow technolo...

This paper presents a model for conducting Internet of Things (IoT) classes based on a web-service oriented cloud platform. The goal of the designed model is to provide university students with knowledge about IoT concepts, possibilities, and business models, and allow them to develop basic system prototypes using general-purpose microdevices and a cloud and service infrastructure. The model wa...
