Cloud Computing – A field of Future

Cloud computing is the provision of computing services such as a database, storage, server, analytics, software, networking, and a lot more on the Internet. The term cloud actually refers to the internet. This technique offers innovation of resources, ease of control, random access, and remote usage of technology in a unique way.

Cloud computing has relieved several concerns so to speak. Some of those are:

·        Cost:

The cost of buying hardware and software, computer racks, special space, IT professionals, and electricity expense to manage the storage, database, and networks in the data centres is reduced exponentially because of cloud computing.

·        Security:

A lot of cloud service providers offer security management and policies that ensure the security of the clients and their sensitive data.

·        Speed:

Most service providers themselves offer speed optimisation so that even a large amount of data processing and services can take place within seconds or minutes.

Other benefits include:

Flexible capacity, Remote availability, Maintenance and management ease, quality control and disaster management.

There are further types of cloud services which are:

Private cloud:

The cloud services that are owned and used exclusively for just one business. It can either be placed at the company’s own data centre or can be located at the data centre of the service provider owned and paid by the organisation.

Public cloud:

Public cloud is owned by a third-party service provider and the services such as storage, database, networking etc., are provided over the internet. These services are owned by the service provider while you access them through the web browser.

Hybrid cloud:

Hybrid cloud is the combination of public and private cloud. It involves on-premises infrastructure, private cloud services and a public cloud. It provides greater flexibility, ease of control and portability.



Cloud computing models:

Cloud computing is a vast field that further comes in different models such as:

  • Platform-as-a-Service (PaaS):

In the Platform-as-a-Service, developers rent development tools, infrastructure, and operating system from the service provider. All the backend management takes place behind the scenes, so it simplifies the tasks of the developer.

  •  Infrastructure-as-a-Service (IaaS):

It is an instant computing infrastructure. IaaS quickly levels up and down according to the requirement and the client will pay only for what they use. Website hosting, testing, development, Web hosting, storage, backup, and recovery are covered by the service provider simplifying the job of the development team.

  • Software-as-a-Service (SaaS):

SaaS provides a complete solution for your software that you purchase on a pay-as-you-go basis from a cloud service provider. You rent the use of an app for your organisation, and your users connect to it over the Internet. All of the underlying infrastructure, middleware, app software, and app data are located in the service provider’s data centre. The service provider manages the hardware and software, and with the appropriate service agreement, ensuring the availability and the security of the app and the data.

  •          Serverless:

Serverless service allows the developers to build applications faster and optimally as the infrastructure is provided by the cloud service provider. The tasks related to the development and management of infrastructure are not visible to the developer for their own good. Serverless as per the name, does not mean that the code is independent of servers. It simply means that tasks regarding infrastructure are not a headache of the development team.

Famous names:

When it comes to the service providers, the big players of the field are:

·        AWS - Amazon Web Services

·        Google Cloud

·        IBM

·        Alibaba Cloud

·        Microsoft Azure

As described earlier, it comes with several advantages and hence large-scale businesses are successfully using the services of the cloud remote services to optimise their business. Given that, It is safe to say that cloud computing is the field of the future.
