What Is Cloud Computing?

In today’s time the number of computer and mobile users is increasing continuously. Due to which priority is being given to data storage in all areas. All types of business whether they are small or big spend money. Apart from this, it also requires IT support and storage hub. Due to which not all types of businesses are able to spend that much money for IT infrastructure and support. Instead cloud computing is a cheap and very good option.

Data can be stored in a more efficient way in cloud computing due to easy computation. Due to which big business are also getting attracted towards cloud computing. The user needs very little hardware and software for cloud computing. For this, the user should be able to use only the cloud computing system and interface software. Which is as easy as running a web browser. The rest of the work is handled by the cloud network automatically. We all have used cloud computing at some point or the other, there are many companies that are providing cloud computing services like Google. Facebook. Amazon etc.

When using the e-mail service, our data is stored on the cloud server and not on the computer. The technology and infrastructure used in a cloud system is not visible to us because it is built using HTTP, XML, Ruby, PHP and other similar technologies. The user can easily connect to the cloud system from his computer, laptop or mobile.

Benefits of Cloud Computing

Due to the low cost, many business organizations use cloud computing service, apart from this, in cloud computing, the user uses the service according to his needs and pays only for the services used. Cloud computing has the following advantages-

  • low cost of IT infrastructure
  • Less computer hardware and software required
  • better performance
  • Fewer maintenance issues and minimal maintenance cost
  • Ease of software updates
  • Compatibility between cloud computing systems and computer operating systems
  • backup and recovery
  • increased data security

Types of Clouds

There are four models of cloud systems and the user can subscribe to any model as per the requirement of his business –

D

Private Cloud:

In this, cloud computing resources are used for a particular business organization.

This system is mainly useful for intra business in which computer resources are controlled and operated under a single organization.

Community Cloud

In this computing resources are provided to the community and the organization.

Public Cloud

Public cloud is commonly used in B2C (Business to Consumer) business. In this computer resources are operated and controlled by the government, academia and business institutions.

Hybrid Cloud

Hybrid cloud This type of cloud is used in both B2C and B2B business. This type of cloud system is called “hybrid cloud” in which computing resources are connected to different cloud.

Cloud Computing Services

Cloud mainly offers three types of services –

  • Software as a Service (SaaS)
  • Platform as a Service (PaaS)
  • Infrastructure as a Service (IaaS)
  • Different types of businesses use these services according to their needs.

SaaS (Software as a Service)

SaaS or software as a service is a “software service distribution” model of cloud computing in which applications are hosted by a service provider or vendor and made available to customers over the Internet. SaaS has become a very popular service delivery model today. Which is going to support Service Oriented Architecture (SOA) or Web Services. This service is made available to the customer all over the world through the Internet.

If we talk about the old method of data storage, in which the user had to buy the software to store the data, then install it on his computer, instead of this, in this new model, the user can easily do this by subscribing to the cloud service on a monthly basis. Apart from this, users can easily use SaaS service on almost all internet enabled devices.

PaaS (Platform as a Service)

It provides a platform to developers where they can build or build applications. This service can be hosted in the cloud itself and the user can access it from anywhere through the Internet.

For example, just as the teacher provides paint colours, paper, brushes, etc. to the children for drawing, the students just have to do the painting, similarly in PaaS the user is provided a platform with various tools where he can use the application. can develop. Here new features are updated from time to time for the users. It provides a platform that supports application development, due to which it is very beneficial for software developers, web developers and other businesses, besides it includes software support and management services, storage, networking, deploying, testing, collaborating, hosting. and applications maintaining facility is also available.

IaaS (Infrastructure as a Service)

Apart from PaaS, IS is a fundamental service of cloud computing. In this, the user can access computing resources on the Internet in a virtual way. It provides various types of computing services and infrastructure such as virtual server space, network connections, bandwidth, load balancers and IP addresses etc. In this, the networks are usually divided into free data centers and in this the hardware resources also work on many servers.

IaaS is a complete package of computing. It is very suitable for small scale business as it has relatively low IT infrastructure cost. By using IaaS computing, any business can save a lot of cost like maintenance, buying new components like -hard-drives, network connections, external storage device etc.
