What is cloud computing? A beginner’s guide

cloud computing

Cloud computing is a revolutionary technology that has transformed the way businesses operate. It allows for the on-demand delivery of IT resources over the internet, with pay-as-you-go pricing. Instead of purchasing, owning and maintaining physical data centers and servers, you can access technology services such as computing power, storage, and databases as needed from a cloud provider like Amazon Web Services (AWS).

Who is using cloud computing?

Organizations of all types, sizes, and industries are utilizing the cloud for a wide variety of use cases, such as data backup, disaster recovery, email, virtual desktops, software development and testing, big data analytics, and customer-facing web applications. For example, healthcare companies are using the cloud to develop more personalized treatments for patients. Financial services companies are using the cloud to power real-time fraud detection and prevention. Video game makers are using the cloud to deliver online games to millions of players around the world.

Top benefits of cloud computing

Cloud computing represents a significant shift from the traditional way businesses think about IT resources. Here are seven common reasons why organizations are turning to cloud computing services:


Cloud computing eliminates the capital expense of buying hardware and software, as well as the costs associated with setting up and running on-site data centers. This includes the racks of servers, round-the-clock electricity for power and cooling, and IT experts for managing the infrastructure. The savings can be substantial.


Most cloud computing services are provided on a self-service and on-demand basis. This means that even vast amounts of computing resources can be provisioned in minutes, typically with just a few mouse clicks. This gives businesses a lot of flexibility and takes the pressure off capacity planning.

3.Global scale

One of the key benefits of cloud computing is the ability to scale elastically. This means that the right amount of IT resources, such as power, storage, and bandwidth, can be delivered at the right time and from the right geographic location.

Types of cloud computing

Not all clouds are the same, and not one type of cloud computing is right for everyone. Several different models, types, and services have evolved to help offer the right solution for your needs.

When considering cloud computing, it’s essential to determine the type of cloud deployment that your cloud services will be implemented on. There are three different ways to deploy cloud services: public, private, and hybrid.

1.Public cloud

Public clouds are owned and operated by third-party cloud service providers. These providers deliver their resources, such as servers and storage, over the internet. Microsoft Azure is an example of a public cloud. With a public cloud, all hardware, software, and other supporting infrastructure is owned and managed by the cloud provider. Users access these services and manage their accounts using a web browser.

2.Private cloud

A private cloud refers to cloud computing resources that are used exclusively by a single business or organization. A private cloud can be physically located on the company’s on-site data center. Some companies also pay third-party service providers to host their private cloud. A private cloud is one in which the services and infrastructure are maintained on a private network.

3.Hybrid cloud

Hybrid clouds combine public and private clouds, bound together by technology that allows data and applications to be shared between them. By allowing data and applications to move between private and public clouds, a hybrid cloud gives your business greater flexibility, more deployment options, and helps optimize your existing infrastructure, security, and compliance.


In conclusion, cloud computing is a revolutionary way for organizations to access and utilize IT resources on an as-needed basis. With pay-as-you-go pricing, businesses can eliminate the capital expenses associated with traditional data centers and servers. Cloud computing is being used for a wide variety of use cases, including data backup, disaster recovery, software development, big data analytics, and customer-facing web applications. The benefits of cloud computing include cost savings, speed, and global scale. There are several different types of cloud computing, including public, private, and hybrid cloud, each with their own unique characteristics and benefits. Organizations can choose the type of cloud deployment that best meets their specific needs and goals. By understanding the different types of cloud computing and their benefits, organizations can make an informed decision on how to best leverage the cloud to drive their business forward.
