To put it simply, Cloud computing is the on-demand availability of computer system resources, especially data storage/ cloud storage and computing power, without direct active management by the user. Cloud computing relies on sharing of resources to achieve coherence and economies of scale. A cloud can be both public and private. A public cloud sells services to anyone on the internet. A private cloud is a proprietary network or a data center that supplies hosted services
to a limited number of people, with certain access and permissions settings.
Cloud computing is still a fairly new service but is being used by a number of different organizations from big corporations to small businesses, nonprofits to government agencies, and even individual consumers.
TYPES OF CLOUD COMPUTING
Cloud computing is not a single piece of technology like a microchip or a cellphone. Rather, it’s a system primarily comprised of services including:
SOFTWARE-AS-A-SERVICE (SAAS)
involves the licensure of a software application to customers. Licenses are typically provided through a pay-as-you-go model or on-demand.
INFRASTRUCTURE-AS-A-SERVICE (IAAS)
involves a method for delivering everything from operating systems to servers and storage through IP-based connectivity as part of an on-demand service.
PLATFORM-AS-A-SERVICE (PAAS)
is considered the most complex of the three layers of cloud-based computing. PaaS shares some similarities with SaaS, the primary difference being that instead of delivering software online, it is actually a platform for creating software that is delivered via the Internet.
FUNCTIONS AS A SERVICE (FAAS)
adds another layer of abstraction to PaaS, so that developers are completely insulated from everything in the stack below their code.
APPLICATIONS OF CLOUD COMPUTING
HYBRID CLOUD APPROACH
While deploying an application, it is important to deploy it in a limited environment to test out the workload and the comfort of using the application. Hence, many companies use the hybrid cloud approach, which creates a platform for infrastructure and applications.
The hybrid cloud involves creating parallel environments in which applications can move easily between private and public clouds.
BUSINESS APPLICATIONS
Business applications are based on cloud service providers. Today, every organization requires the cloud business application to grow their business. It also ensures that business applications are 24*7 available to users.
E- COMMERCE APPLICATION
With the help of e-commerce applications in the cloud, users and e-business allow responding quickly to the opportunities which are emerging. Cloud-based e-commerce applications allow the companies, business leaders to evaluate new opportunities and things are done with the minimum amount possible.
STORAGE
Cloud computing allows us to store information (data, files, images, audios, and videos) on the cloud and access this information using an internet connection. As the cloud provider is responsible for providing security, they offer various backup recovery applications for retrieving the lost data.
MANAGEMENT APPLICATIONS
Cloud computing offers various cloud management tools which help admins to manage all types of cloud activities, such as resource deployment, data integration, and disaster recovery. These management tools also provide administrative control over the platforms, applications, and infrastructure.
