Cloud Services computing uses computing power, data storage or applications of a local data center, which stands across a grid of a large number of users on subscription basis. At first glance, the types of cloud computing seem simple: public, private or a hybrid mix of both. Cloud Computing SLAs - Exploitation of Research Results iii Abstract The rapid evolution of the cloud market is leading to the emergence of new services, new ways for service provisioning and new interaction and collaboration models both amongst cloud providers and service ecosystems exploiting cloud resources. SaaS, PaaS and IaaS layers are considered for associated security risks and problems. These are just some of the basic services offered over cloud networks. Juliane. Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user.The term is generally used to describe data centers available to many users over the Internet.Large clouds, predominant today, often have functions distributed over multiple locations from central servers. Many companies are getting on board as the cloud architecture allows them to have access to technology-enabled services without having to upgrade their hardware and software, maintaining and updating a complex IT infrastructure and without needing a full IT team onboard. And, in some cases, especially for existing applications where architectures are too complex to move or the cost-benefit ratio is not optimal, cloud may not be the right choice.
