Cloud Computing Services

Cloud computing is the delivery of different services through the Internet, including data storage, servers, databases, networking, and software.

Cloud-based storage makes it possible to save files to a remote database and retrieve them on demand.

Cloud Computing Services can be both public and private—public services are provided online for a fee while private services are hosted on a network to specific clients.

Cloud computing refers to the web-based computing, providing users or devices with shared pool of resources, information or software on demand and pay per-use basis. It frees a user from the concerns about the expertise within the technological infrastructure of the service.

It allows user and little companies to form use of varied computational resources like storage, software and processing capabilities provided by other companies.

The cloud services are often divided into three categories:

  • Infrastructure as a Service (IaaS),
  • Platform as a Service (PaaS), 
  • Software as a Service (SaaS).

According to NIST Cloud Computing is composed of:

• 5 Essential Characteristics

• 3 Service Models

• 4 Deployment Models

Essential Characteristics

1. On-Demand Self-Service – A user can get resources like server time or storage according to his/her requirement and without any other human intervention.

2. Broad Network Access – Computing and storage capabilities can be accessed from anywhere and by any means over the broad and easily accessible network.

3. Resource Pooling – Large amount of multitenant and location independent physical and virtual resource pool which can be dynamically assigned.

4. Rapid Elasticity – The provisioning of the capabilities is so elastic and agile that it gives a sense of infinite capacity. Scaling up and Scaling down of capabilities is very fast.

5. Measured Services – Customer has to pay for the services he/she used and the quantity or the time quantum for which the services were used.

Service Models

1. Software as a Service (SaaS) – The customer uses the application service provided by the cloud to perform the computations and is not bothered about underlying hardware or infrastructure like storage, Servers, O.S, bandwidth requirements etc. . The consumer does not have any control over the Application, storage, servers, O.S, networking capabilities etc.

2. Platform as a Service (PaaS) – In this model cloud provider offers the customer with the platform on which the user can deploy his/her application and use the underlying infrastructure to run the application. The consumer has control over only the application but not on any underlying hardware, Software, O.S, networking capabilities etc.

3. Infrastructure as a Service (IaaS) – This provides consumer with the Storage, Server, O.S, firewalls and other hardware capabilities but not with the underlying cloud infrastructure.
