Data storage
Data centers are the facilities where cloud storage system is done. For a small level, a cloud storage system needs only one data server connected to internet, but they depend on hundreds of data servers as the information for their clients’ needs to be accessed round the clock irrespective of any problems like malfunctioning of computer hardware, internet connectivity, power supplies etc.
Types of cloud computing
Cloud computing providers offer services to their clients based on three fundamental models. First one is the Infrastructure as a service (IASS) which is the basic cloud service model that includes virtual machines, storage, servers, load balancers and networks. The next one is the platform as a service (PASS) which is a computing platform or solution stack which includes execution runtime, web server, development tools and database. The last is the software as a service (SAAS) where the cloud providers install and operate application software which includes Email, games, virtual desktop, CRM etc.
