Testing of Cloud Applications in the Cross-Cloud Environment

Cloud computing is the new paradigm to deliver all the hosted services over internet on demand. The ultimate goal of cloud computing paradigm is to realize computing as a utility. The cloud is rapidly maturing towards its goal to support a wide variety of enterprise and consumer services and real-world applications. Recently a movement towards cross cloud also called as multi-clouds or inters clouds or cloud-of-clouds has emerged which take advantage of multiple independent cloud provider offers for cloud resilience and dependability. This cross cloud represents the next logical wave in computing, enabling complex hybrid applications, cost and performance optimization, enhanced reliability, customer flexibility and lock-in avoidance. Providing testing as a service (TaaS) in cross clouds become hot topics in industry. Testing heterogeneous e-commerce sites, Software as a Service solutions, and Cloud based applications is extremely challenging. Many vendors are offering cloud testing services to support cloud-based applications. However, there is a lack of clear understanding about cloud testing in terms of concepts, issues, challenges, and needs. This paper surveys recent research related to testing of cross clouds applications and also simulates multilayer testing, service level agreement based testing on the large scale commercial testing environment. This paper proposes to build, integrate and implement an application prototype that initiates some of the above stages on a cross cloud platform. Our experimental results also shows efficient data protection of cross cloud testing.
