What is Cloud Computing and Why Was It Needed?

As a business owner, you might have started watching many business entities, especially your competitors have a paradigm shift in their IT (Information Technology) infrastructure and adopt the “cloud”. The word cloud has gained tremendous significance over the last few years. Do you know why all these small, medium and large companies abandoned their previous technologies and switched to cloud-based systems?

Why Was It Needed?

As computer technologies have updated over time, and the requirements began increasing for organisations, they had to spend a great deal of time and money on their scaling needs. With the IT infrastructure based on premises, scaling was difficult and slow, and companies were unable to meet their computing needs.

Cloud computing offered these companies an opportunity to meet their computing needs from optimised remote and virtual data centres. These servers provide services related to software, hardware and other IT resources. Companies can pay cloud computing service providers and use their remote servers for their purposes. Thus, companies save from the slow and costly on-premises IT infrastructures.

What Exactly Is Cloud Computing?

Cloud Computing refers to the usage of computing resources available on the internet to store or process your data instead of using on-site resources. The term “cloud” originated actually from the early computing days when the internet was newly invented and represented as a cloud in diagrams. These resources can be databases, storage, servers, networking, software, analytics and many more.

Real World Examples

Many tech giants have incorporated cloud into their products and services. One of the most common examples is Google Drive on which you can store your files and data online. Another example is Apple iCloud which uses cloud computing to store a customer’s information like contacts and calendars. Moreover, Amazon also uses the technology to store music in MP3 format through Amazon Cloud Drive.

Cloud Models

There are four distinct models in cloud computing.

Private Cloud

A private cloud is reserved for a single business entity and is a private network. It is highly secure and not shared with anyone.

Public Cloud

Public cloud is considered the most efficient. The cloud provider owns and manages the infrastructure then shares resources with an organisation. 

Hybrid Cloud

As the name suggests, hybrid cloud uses the features of both public and private clouds. It runs some resources from a public cloud others are provided from a private cloud depending upon a company’s needs.

Community Cloud

Community cloud refers to a cloud where different companies can share resources. It is a common cloud in conglomerates where different sectors of a conglomerate require sharing of data or government institutions where public data needs to be utilised by different departments.

If like most businesses your IT budget is limited then you need to be open to change. It is 2018, and all the successful businesses have incorporated the cloud into their systems. Because the cloud is not just a service, it is a need of the hour!
