Cloud Computing

Cloud computing refers to the on-demand delivery of various computing resources over the Internet. It provides online data storage, applications, and infrastructure.

Cloud Deployment Models

A cloud deployment model refers to the type of cloud infrastructure architecture used to implement a cloud solution.

The following are the different types of cloud deployment models, each of which differs in terms of implementation, hosting, and accessibility level.

• Public Cloud

In this model, a service provider provides services to the general public through the internet. Storage capabilities, software, and virtual machines are examples of resources that may be available depending on the provider.

• Private Cloud

The term Private Cloud may also refer to an Internal Cloud or a Corporate Cloud. In this model, services are made accessible within the organization. Organizations use it to create and run their own data centers internally or through a third party.

• Hybrid Cloud

This model is a combination of private cloud and public cloud. In a hybrid cloud system, the public cloud is used to perform non-critical activities and the private cloud is used to perform critical activities.

• Community Cloud

In this model, services are made accessible to a group of organizations to exchange knowledge between the organization and a particular community. It is owned, maintained, and run by one or more community groups, a third party, or a combination of these organizations.

Cloud Computing Service Models

Cloud computing has three main service models. Each type of service model offers different levels of control, flexibility, and management, allowing you to choose the best collection of services for your needs.

• Infrastructure as a Service (IaaS)

IaaS is the simplest option for organizations. It allows access to basic resources including physical machines, virtual machines, virtual storage, and much more. IaaS allows an organization to move its hardware to the cloud by renting servers and data storage rather than buying and maintaining its own infrastructure. IaaS products include Amazon Web Services (AWS), and Microsoft Azure.

• Platform as a Service (PaaS)

PaaS is a common option for companies that want to develop unique applications without making significant financial investments. An organization may use PaaS to gain access to a pre-defined framework for software development that can be used to design, test, and run applications. Google App Engine, web servers, and SQL servers are examples of PaaS products.

• Software as a Service (SaaS)

SaaS is the most widely used cloud application service, and it is quickly becoming the dominant way for businesses to access software applications. Different organizations use SaaS to gain access to a particular software application hosted on a remote server and operated by a third-party provider. Popular SaaS products include Salesforce, Workday, and Microsoft Office 365.

Benefits of Cloud Computing

• Cloud services are platform independent.
• Cloud computing is extremely cost-efficient due to its high reliability and optimal use.
• Cloud infrastructure provides the highest level of protection.
