What is Cloud Computing?
Cloud computing is an internet-based processing solution in which large sets of remote hosts are networked to permit centralized information storage space and web usage of computer system solutions or sources.
Using cloud processing, companies may use provided processing and storage space sources without creating, running, and increasing infrastructure independently.
Cloud processing is a design that permits the listed functions here.
• People can provision and launch sources on-demand.
• Sources are scaled up or down instantly with regard to the load.
• Sources tend to be available over a system with correct protection.
• Cloud providers can allow a pay-as-you-go design, in which clients tend to be recharged in line with the style of sources and per consumption.
Types of Clouds
You will find three forms of clouds − Public, professional, and crossbreed cloud.
Public Cloud
In the public cloud, third-party service providers make resources and services available to their customers via the Internet. The customer data and related security are part of the service providers’ owned infrastructure.
Private Cloud
A private cloud also provides features that are almost similar to those of a public cloud. Still, the data and services are managed by the organization or by a third party only for the customer’s organization. In this type of cloud, central control is over the infrastructure, so security-related issues are minimized.
Hybrid Cloud
A hybrid cloud is a combination of private and public clouds. The decision to run on a private or public cloud usually depends on various parameters, such as the sensitivity of data and applications, industry certifications, and required standards and regulations.
Cloud Service Models
You will find three kinds of solution designs in the cloud − IaaS, PaaS, and SaaS
laaS
IaaS stands for Infrastructure as a Service. It provides users with the capability to provision processing, storage, and network connectivity on demand. Using this service model, customers can develop their applications for these resources.
PaaS
PaaS stands for Platform as a Service. In this model, the service provider provides various services, such as databases, queues, workflow engines, e-mails, etc., to its customers. The customers can then use these components to build their own applications. The service provider handles the services, availability of resources, and data backup, which helps the customers focus more on their application’s functionality.
SaaS
SaaS stands for Software as a Service. As the name suggests, third-party providers provide end-user applications to their customers with some administrative capability at the application level, such as the ability to create and manage users. Also, some level of customizability is possible, such as the customers’ use of their own corporate logos, colours, etc.
