A great example of this is GoGrid's 10,000% Guaranteed SLA. Large clouds, predominant today, often have functions distributed over multiple locations from central servers. As one would expect, the different stack-specific clouds align with the most popular software stacks out there. Although the SLA is a good indicator of any provider's level of commitment, knowing the real uptime levels of a particular cloud provider is a trickier proposition. Cloud computing is all about renting computing services. In the 1980s, new, less expensive, and compact hardware components got invented. Cloud computing is a pay-per-use model for enabling available, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. These are distributed systems and its peripherals, virtualization, web 2.0, service orientation, and utility computing. … Some key technologies for Cloud computing, such as virtualization and the Service-Oriented Architecture (SOA), bring in special challenges to service performance evaluation. Gmail, Yahoo mail, Facebook, Hotmail, Orkut, etc are all the most basic and widely used examples of cloud computing. These systems were managed in a separate large room or hall with all necessary power backup, cooling, and data backup maintenance. In other words, GoGrid offers a 100% uptime guarantee.
