So the point is, with on-premise data center, our organisation is reponsible for managing pretty much everything. As with other significant developments in technology, many vendors have seized the term cloud and are using it for products that are outside of the common definition. As the name implies, with Infrastructure as a Service, you rent or lease IT infrastructure from a cloud service provider like Microsoft Azure, Amazon Web Services or some other cloud provider. There is a reduced financial risk for organisations. If we are not using cloud, we manage everything on-premise. When the customer releases the resource, the cloud provider must ensure that next customer to rent the resource does not observe data residue from previous customer. AWS offers storage services such as Simple Storage Services (S3) and Glacier, as well as compute services, including its Elastic Compute Cloud (EC2)… It provides near unlimited scalability. Cloud service providers, for example, Amazon, Microsoft and Google, have data centers all over the world. Get them shipped over. In addition to Infrastructure as a Service, we also have Platform as a Service (also called PaaS) and Software as a Service (also called SaaS). Functions as a Services (FaaS or Serverless Computing), Procuring physical servers, storage and related hardware, Setting up the server room or data center, Make sure there is main power supply, back-up power supply, cooling system etc are in place. Cloudy Concepts: IaaS, PaaS, SaaS, MaaS, CaaS & XaaS. To understand this better, take a look at the following diagram. In our last tutorial, we discussed thebest Cloud Computing Tutorial.Here, we will explore Cloud Computing architecture with diagram and example.

Allows to store copies of particular data at different locations. In an IaaS model, a cloud provider hosts the infrastructure components traditionally present in an on-premises data center, including servers, storage and networking hardware, as well as the virtualization or hypervisor layer. It is used to dereference various low-level details of underlying network infrastructure like physical computing resources, location, data partitioning, scaling, security, backup, etc. IaaS offers an isolated environment to individual customers through hypervisor.
