What is Cloud Computing? Cotegories of Cloud computing
Cloud computing is growing rapidly and involves potentially greater exposure to security threats and privacy breaches, especially when it comes to private and public cloud. It is a new way of providing computed, resources and applications on-demand. It has become on of the most important research topics in computer science and information system today.
Three main cotegories of Cloud-computing are:-
1. Software as a service (SaaS).
2. Platform as a service (PaaS).
3. Internet as a service (IaaS).
1. Software as a service (SaaS):~
A form of cloud computing,SaaS is a software distribution model in which a third- party provider hosts application and makes them available to costumer’s over the internet.
2. Platform as a service (PaaS):~
A form of cloud computing, PaaS provides a platform allowing costumer’s to develop,run and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.
3. Internet as a service (IaaS) :~
A form of cloud computing,IaaS provides vertualised computing resources over the internet. It is cloud model where units of computation,in the form of vertual mashines and/or storage,are allocated to costumer’s,who then Access their assigned resources via wide area network (WAN).
