What is Cloud Computing

Cloud computing is a kind of computing that is internet based providing shared processing data and resources to computerized devices and computers on demand. It enables on-demand access to a shared pool of configurable computing resources such as stockpiling, applications, networks, servers and services which can be released and provisioned rapidly with minimal management effort.

Cloud computing or on-demand computing enables the delivery of storage solutions providing enterprises and users with various capabilities and abilities to process and store their data and information in 3rd party centers of data. It depends on sharing of company or business resources to achieve and succeed economy of scale and coherence.

On-demand computing enables companies, users, and enterprises to compute resources rather than having to maintain already built computing infrastructures. Cloud computing has improved on-demand computing optimism by providing several attractive and premium benefits for end users and businesses. 3 of the chief merits of on-demand computing include:

Elasticity: when computing needs increase companies can quickly scale up and when computing needs decrease businesses can scale down easily.

Self-service provisioning

Pay per use: On-demand computing allows users to pay only for the workloads and resources they use.

On-demand computing services can be hybrid, public and private.

Private on demand services can be delivered to internal users from a business' data center. This exquisite model offers convenience and versatility while preserving security, control, and management. Internal customers may not or may be billed for services through information technology chargeback.

In the public on demand computing, a 3rd party provider provides the on-demand service over the Internet. Public or open on demand services can be sold on-demand, typically by the hour or minute. Customers, businesses, and users only pay for the CPU bandwidth, cycles and storage they consume. Leading public on demand providers include IBM/Soft Layer, Google Compute Engine, Amazon Web Services (AWS) and Microsoft Azure.

How to blend on-premises IT with the cloud

Hybrid cloud is a combination of on-premises private cloud and public on demand services with automation and orchestration between the 2. Companies can operate sensitive applications or mission-critical workloads on the private on-demand services while using the public on-demand services for workloads that must scale on-demand. Hybrid on demand services creates a scalable, automated and unified environment which takes full advantage of all that a public on-demand service infrastructure can offer while maintaining total control over mission data that is critical.

Cloud is divided into 3 broad service categories: software, infrastructure and platform.

Infrastructure as a service providers provide a virtual server storage and instance, as well as application program interfaces that let users, businesses or enterprises migrate workloads to a virtual machine. Users, businesses or enterprises have an allocated storage capacity and access, stop, start and configure the virtual machine and stockpiling as desired. IaaS providers provide extra-large, large, medium, small and compute and memory-optimized instances.

Platform as a service providers host and provide development tools on their infrastructures. Users, businesses or enterprises access those development tools over the Internet using application program interfaces, gateway software or web portals.

Software as service model provides software applications over the Internet commonly called Web services.
