Cloud computing has shortened the gap between a user and the locations of his resources and data. With its help, he can access his property from anywhere and any time. Time and distance are no more a criterion for web user. All thanks to Computer Cleaning and its different kinds of services that made this action possible and that too very effectively.
Delivering of computing resources over the internet is typically the service provided by cloud computing. Although there are a number of services provided by a cloud computing company, three basic models are generally used at large. They are:
IAAS- Infrastructure as a Service
SAAS- Software as a Service
PAAS- Platform as a Service
These three different models define the foundation of a web hosting service by providing the three necessary components required for hosting a website. IAAS provides the basic infrastructural needs like the virtual machines, server, storage house, etc. that are very necessary to access a website or the relevant data stored by a user. Through SAAS, cloud providers eliminate the need to install full-fledged software and use it directly by accessing it through the clouds. PAAS provides the required operating system, programming language execution environment, database and the web server. Over wholly speaking, it offers the platform to a user who already has his software and infrastructure arranged.
Cloud computing services don’t end here. It has been further provisioned into many more forms to provide users with as much convenience as they can. For instance, you can rent a large amount of storage space by using STaaS (Storage as a Service) or you can secure your files by renting high-end security systems through SECaaS (Security as a Service). And, there are a lot more. Each service has a definite constraint and a model that suits only the type of work gets to deal with.
