cloud computing

Overview of Cloud computing

Cloud computing was introduced in 1996 in compact internet documents. In 1999 Salesforce became the first company to provide enterprise applications over the internet. Amazon introduced Amazon Web Services (AWS) in 2002 and Elastic Compute Cloud (EC2) in 2006. In 2009 Google Workspace was by google, and Arena by Microsoft. All these are the cloud computing platforms that provide online storage data services using different platforms.

  • Cloud computing services involve delivering services like data storage, databases, servers, software, networking, etc.
  •  Business companies use cloud computing to increase productivity, speed, efficiency, performance, cost saving, security, etc.
  • Cloud computing architecture also provides this facility to save files and record data to a secure database which could be recovered on demand.
  • Cloud computing deployment is more beneficial for large-scale businesses as it provides offline data and proper backup solutions.
  • The security of Cloud computing is robust.
  • Cloud computing provides users to Store application data files on the server and has access to these file applications anytime through the internet.
  •  Cloud computing provides the latest way for companies to connect their services remotely without physical access by their employees and users.
  • Cloud computing architecture provides security, flexibility, scalability, efficiency, and low cost for its products.
  •  We can share our data easily on an online platform using the internet and also access these data in other locations with security.
  • Cloud computing deployment models provide an easy way to share information and give us an online storage capacity in different sizes via different platforms used by different companies.
  •  Now many companies are working with this technology and providing these services to users.

Examples of cloud computing

Some of the most common examples of cloud computing:-

  • Dropbox
  • DigitalOcean
  • Microsoft Azure
  • Salesforce

Kinds of cloud computing services

Cloud computing provides services in the following:-

  • Streaming of videos
  • Inspection of data
  • Testing and modelling of apps
  • Strong backup security
  • Efficient storage capacity
  • Data recapture service
  • Email services
  • Provide software with easy process

Types of Cloud computing

There are three types of cloud computing services which are described below:-

  • Software as a service (SaaS)
  • Infrastructure as a service(IaaS)
  • Platform as a service(PaaS)

Software as a service(SaaS)

Software as a service is an end to end-user application. This service is delivered on a subscription basis as it delivers software applications on demand. This can be used from anywhere; adding to this, it can be used on multiple devices per requirement.

Example of software as a service – we have easy access to emails regarding sending or receiving mails without having any burden of operations and maintaining the mails. Plus point of SaaS is it provides proper security of data.

Infrastructure as a service(IaaS)

mainly provides access to computer networks like virtual or hardware. This is most popular in IT resources as it provides the maximum flexibility for various management controls over the different resources of Information Technology. It also has control over various information technology resources.

Platform as a service(PaaS)

This service provides a facility for businesses to focus on the development and management activities of the business. This has become possible only through the efforts provided by our services because PaaS vanishes the requirements of the organisation to manage the infrastructure of the business like they provide access to hardware and operating systems.

Other types of cloud

There are some other types of clouds, including:-

  • Private cloud
  • Public cloud
  • Community cloud
  • Hybrid cloud

Private cloud

Private clouds are used and operated by a single user. It provides the users with various functions of computers. It works only on private infrastructure. In this cloud, there are different schemes regarding the usage of cloud details and billing of each department of the organisation.

Some of the most common private cloud providers are:- 

  • Elastic-private cloud
  • Microsoft providers
  • Ubuntu
  • HP data-providing centres

Merits of private cloud

There are various merits of private clouds, such as:-

  1. Foundation certifies SLAs
  2. Aggregability with excellent procedures and operations.
  3. Protection of customers’ particular

Foundation certifies SLAs:- private clouds include services like data reduplication, maintenance, data recovery, appropriate system monitoring, specific operations, and services.

Aggregability with excellent procedures and operations:-various different procedures and steps are to be followed for developing, maintaining, and executing the organisation’s standards since it becomes difficult or impossible to follow all the strict rules regarding standards.

Protection of customers, particular:-In private clouds, protection and security of data are not as strong as in hybrid clouds. But the professional ensures that the customer’s personal or sensitive data should not be out of range. The main necessary for keeping data, files et,c., safe is to hire a professional who can have proper access to the private clouds.

Demerits of private cloud

There are some demerits also of private cloud as well as merits

  1. Proficiency required
  2. Cramped area of operating

Proficiency required:-Only skilled, expert, or professional private cloud users can easily control or operate the services properly. This is mandatory to be used by professionals because private clouds do not provide robust protection, so private or sensitive data should not get out of the device. This service requires a professional to keep an eye on the files properly.

Cramped area of operating:- As the private clouds are single users, their area is restricted to only one server. It is only used with a prescribed or a particular area. That is the reason why the area of operating private cloud is cramped.

Public cloud

Public cloud is the service managed by the party who provides these services to the public through the internet. The public cloud is used by several or multiple users, not only by a single user, as in the private cloud. The public cloud is a wider concept as compared to the private cloud. Most businesses require a computing cloud that can easily be accessed anywhere or a cloud that can be separated. Public clouds become beneficial for the new and small-scale introduction of business in society, as they can start their business with a small investment and rely on the public cloud for their investment in information technology resources.

Community cloud

Community cloud is used in the organisation where the information regarding concerns and tasks have been shared through a single medium. These cloud services can be handled by the management of the organisation of the person assigned the responsibility of conveying the different organisational tasks. Through the community cloud, an organisation can easily inscribe the various or particular requirements of the organisation, enterprise, etc.

Community cloud sectors

These are some of the following sectors in which community clouds are mostly used

  1. Health industry
  2. Research industry
  3. Energy and fundamental industry
  4. Media industry

Health industry

It is very beneficial for healthcare industries as it conveys any information, knowledge, and content of the health industry at the global level. It also conveys sensitive data regarding the health industry within the prescribed time limit.

Research industry

most of organisations with a keen interest in scientific computing or science can share a large distribution of infrastructure.

Energy and fundamental industry

community cloud is used in energy and fundamental industry for the congregation of solutions to management, operation, formation, disposition, symmetry, and other workings. 

Media industry

Media is vast, requiring prompt, easy, simpler content with cost benefits. The basic purpose of this community cloud computing service is to increase the effectiveness and efficiency of the content. The media industry opts for community cloud for vast data, difficult work pressure, huge workflow, computer tasks, etc.

Hybrid cloud

Hybrid cloud is a combination of both private as well as public clouds. That’s why it is also known as heterogeneous clouds. Hybrid clouds take the benefits of both private and public funds.

Merits of Hybrid cloud

These are the merits that the organisation can have after having hybrid cloud services

  • Cheap cost
  • Strong security
  • Speedy working

Cheap cost:- As it is made up of a distribution system, hybrid clouds are available at a very cheap cost compared to the other clouds.

Strong security:- The foremost essential of the hybrid cloud is that it works on distribution systems, providing safe and secure end-to-end user data.

Speedy working:- Hybrid clouds are very cheap, and their working is also vast and fast. It develops different distribution channels which make it possible for the fast working of the organisation.
