What is Cloud Computing?

Cloud computing is also known as on-the-line computing. It is a kind of Internet-based computing service, which provides shared processing resources to computers and to other devices on demand. It is a model for enabling ubiquitous on-demand access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services), which can be rapidly released with minimal management efforts.

Cloud computing and storage solutions provide users and enterprises with various capabilities of storing and processing their data in third-party data centers.

It relies on sharing of resources to achieve coherence and economy of scale similar to a utility (like the electricity grid) over a Network

How cloud computing services work

Cloud computing services have several common attributes:

Virtualization

Cloud computing utilizes server and storage virtualization extensively to allocate/reallocate resources rapidly

Multi-tenancy

Resources are pooled and shared among multiple users to gain economies of scale

Network-access

Resources are accessed via web- browser or thin client using a variety of networked devices (computer, tablet, smartphone)

On-demand

Resources are self-provisioned from an online catalogue of pre-defined configurations

Elastic

Resources can scale up or down, automatically

Metering/Chargeback

Resource usage is tracked and billed, based on service arrangement

Among the many types of cloud computing services delivered internally or by third party service providers, the most common are:

Software as a Service (SaaS)

Software that runs on computers are owned by the SaaS provider, and is managed on user computers. The software is accessed over the public internet and generally offers a monthly or yearly subscription

Infrastructure as a Service (IaaS)

Compute, storage, networking, and other elements (security, tools) are provided by the IaaS provider via public internet, VPN, or dedicated network connection. Users own and manage their operating systems, applications, and information, that running on the infrastructure, which are paid according to the usage.

Platform as a Service (PaaS)

All software and hardware required cloud-based applications are provided by the PaaS provider via public internet, VPN, or dedicated network connection Users pay according to the usage of the platform and also they can control how applications are utilized throughout their life.
