Cloud Computing: Introduction, Characteristics and its Advantages

Posted on February 05, 2020 by Author

In this tutorial, we provide its Basic and Advanced Concepts of Cloud Computing like Introduction, Characteristics & Advantages. Our Cloud Computing Tutorial is designed after keeping in focus to make it easier for beginners to professionals.

It is a virtualization-based technology which provides us to create, edit, and customize applications via an internet connection. Cloud technology includes so many things like development platform, hard disk, software application, and database, etc.

What is Cloud Computing?

Cloud computing refers to a network or the internet. It refers to a technology that uses remote servers on the internet to store, manage, and access all the data online. The data could be anything for eg:- files, pictures, docs, audio, video, and many more.

Here are the following operations which we might do while using cloud computing:

  • Developing new applications and services
  • Storage, Backup, and Restoration of data
  • Receiving blogs and websites
  • Delivery of software on demand
  • Analysis of data
  • Streaming videos and audios

Why Cloud Computing?

From smaller to a larger scale in IT companies, everyone follows the rituals to provide the IT Infrastructure. That means for any IT company, we need a Server Room which is the basic and the foremost need of IT companies.

And in that server room, there must be a database server, A mail server, networking, firewalls, routers, modem, switches, QPS (Query Per Second means refers to the queries or load which was handled by the server), A configurable system, quick net speed, and maintenance engineers are required as well as their necessities.

To enable or establish such IT infrastructure, lots of expenditure is expected. And Overcoming all these problems and reducing the cost of IT infrastructure, Cloud Computing comes into existence and is known as a good option.

Characteristics of Cloud Computing

Here are the Characteristics of cloud computing

  • 1. Speed and Great Agility

    The cloud works in a Dispense and Distributed computing environment. It helps in sharing the resources among the users and works very fast.

  • 2. High Availability and is a very Reliable Option

    The availability of servers is high and more reliable in comparison to other options. In this field the chances of infrastructure failure are minimum and it is a very reliable option for IT Companies.

  • 3. Highly Scalable

    Cloud provides an "on-demand" provisioning of resources on a very large scale, without having engineers to peak load for it.

  • 4. Multi-Sharing Options

    While using cloud computing multiple users and applications can work more efficiently with less-cost by sharing common infrastructure.

  • 5. Device and Location Independence

    Cloud computing allows the users to access systems applying a web browser regardless of their location or what device they use e.g. PC, mobile phone, etc. As infrastructure is off-site and reached via the Internet, users can join from anywhere.

  • 6. Maintenance

    Maintenance of cloud computing applications is more comfortable since they do not need to be installed on per user's computer and can be accessed from various places. So, it reduces the cost also.

  • 7. Low Cost

    By using cloud computing, the cost will be reduced because to take the services of cloud computing, IT company need not set its own infrastructure. and pay-as-per usage of resources.

  • 8. Services in the pay-per-use model

    Application Programming Interfaces (APIs) are given to the users so that they can access services on the cloud and pay the charges as per the usage of services.

Advantages of Cloud Computing

As we all know, Cloud computing is Trending Technology. Almost every company using it. Below you can see some of the Advantages of Cloud Computing.

  • 1. Data Back-up and Restore

    Once the data is Uploaded or Stored in the cloud. It Becomes Easier to back-up and restores that data using the cloud.

  • 2. Improved Collaboration

    Cloud applications improve collaboration by allowing groups of people to quickly and easily share information in the cloud via shared storage.

  • 3. Excellent accessibility

    Cloud allows us to quickly and easily access store information anywhere, anytime in the whole world, using an internet connection. An internet cloud infrastructure increases organization productivity and efficiency by ensuring that our data is always accessible.

  • 4. Low maintenance cost

    Cloud computing reduces both hardware and software maintenance costs for organizations.

  • 5. Mobility

    Cloud computing allows us to easily access all cloud data via mobile.

  • 6. Unlimited storage capacity

    Cloud offers us a large amount of saving capacity for storing important data in one place such as video, documents, images, etc.

  • 7. Data security

    Data security is one of the biggest advantages of cloud computing. Cloud offers many advanced features related to security and ensures that data is securely stored and handled.

Future of Cloud Computing

Cloud Computing holds a commitment to new innovations. The workload of organizations is expected to be handled in cloud data centres. Cloud Computing can be held as a necessary part of most businesses in the future.

Some upcoming predictions for years are as follows:

  • There will be many applications on the Cloud, while new software will be created on the Cloud to provide faster deployment of the applications. From 2014, half of the enterprises gave 10% of their annual budget on cloud services. This share is required to improve in the future.
  • Platform as a Service will be followed by more companies because it reduces the IT costs and speeds up application development.
  • Cloud-based graphics technologies will be in demand and with this technology, future users will be able to run graphically intense applications.
  • Improved competition in the Cloud space is likely to result in bigger discovery and services.

Cloud Computing - Jobs and Salary

Cloud Computing is a known word which is Heard by so many people. It gives more benefits in a short time with less expense and low training costs. It helps in globalizing the work with the help of the Internet.


Let us summarize what we have learned in this lesson.

  • Cloud Computing uses large groups of remote servers hosted on the Internet to store and access applications and computer data.
  • Public, Private, Community, and Hybrid comprise the Cloud Deployment Models.
  • Infrastructure as a service, Platform as a service and software as a service are the three Cloud Service Models.
  • In the Cloud, the infrastructure is not purchased. Therefore, the initial and recurring expenses are lower than in traditional computing.
  • Monitoring as a Service, Cloud Migration as a Service, Communication as a Service, and Anything as a Service are some of the emerging cloud services.
