TTC 2014 - 2nd International Workshop on Testing The Cloud

Cloud computing is everywhere, inevitable: originally a layered abstraction of an heterogeneous environment, it has become the paradigm of a large-scale data-oriented system. And while it has some interesting features (easy deployment of applications, resiliency, security, performance, scalability, elasticity, etc.), testing its robustness and its reliability is a major challenge. The Cloud is an intricate collection of interconnected and virtualised computers, connected services, complex service-level agreements. From a testing perspective, the Cloud is then a complex composition of complex systems, and one can wonder whether anything like a global testing is possible? But if the answer is no, what can we conclude from partial tests? The question of testing this large, network-based, dynamic, composition of computers, virtual machines, servers, services, SLAs, seems particularly difficult.
