TYPE OF CLOUD SERVICES (IAAS PAAS SAAS)
Most of the cloud services fall in three broad categories of cloud computing Infrastructure As A Service (IAAS), Platform As A Service (PAAS), Software As A Service (SAAS). they are also known as cloud computing stack.
Infrastructure As A Service (IAAS)
its the most basic category of cloud computing services, what you do is that you rent out the infrastructure of your dire need by a cloud provider and pay it as per need and utilisation.
Platform As A service (PAAS)
its such a category that provides you with the environment all that you need for your apps and work. without worrying about the infrastructure that needs to run it i.e. storage, memory (ram), and all other hardware need.
Software As A Service (SAAS)
Software Applications are being developed and delivered to the community over the internet typically or say common practice such services are charged over subscriptions. with SAAS the cloud providers eventually deals with all the application, its infrastructure, it upgrade maintenance and all the other expenses the customer has not to worry about it.
TYPES OF CLOUD DEPLOYMENT

this kind of cloud deployment model is owned and operated by a third party vendor, they use them in deliverance of their own cloud services/resources i.e. servers, storage, hardware, software other supporting infrastructure that one need for own business. one can access and manages the services by only the utilisation of web browser.
this kind of deployment model is owned by a single organisation or entity. the deployment of it can take place on premises as a local datacenter. some invest to the cloud providers for having their own private cloud for their business.
the combination of public and private cloud make up an hybrid cloud. it allows sharing of data and application between them. the hybrid makes the business more flexible and large.
So, cloud computing works different dependant on the provider, but it makes the industry ease especially for IT pros it provide powerful dashboard to the community.
