Cloud Computing is another concept among the major technological and computing innovations that have taken the cyber age by storm. The domain is in use in almost every type of industry that requires computing or has computing and technology at the heart of its day-to-day operations. 

While the ideation of Cloud Computing can be traced to the mid-20th century, it’s widespread usage has occurred over the last decade or so. So the question for those of us who are unaware starts with What is Cloud Computing? 

In this blog, you will be getting a comprehensive idea about Cloud Computing. We will be learning about:

i.) What is Cloud Computing 

ii.) The idea behind Cloud Computing 

iv.) The types of Cloud Computing:

v.) Benefits of Cloud Computing 

vi.) Business Impacts of Cloud Computing 

vii.) Careers in Cloud Computing: What is there for you?

As for now, let’s move into the concept.

Cloud Computing for beginners: What is Cloud Computing?

A simple definition of Cloud Computing is that Cloud Computing is the aggregate availability of resources for a user to use. These resources are decentralized, meaning that no source controls these resource allocations. Although for storage there are central servers that help in the same. 

Consider an easy example to be cloud storage platforms like Google Drive, Dropbox, and Microsoft OneDrive.

The idea behind Cloud Computing 

Cloud Computing was considered as an alternative since it offers two very important computer resources abundantly:  Data Storage and Computing Power. 

While this was also being offered by traditional storage systems, the point was that they were mostly hardware-based and might quickly run out of space.

The only alternative for this was that you needed to rent or buy more space, which meant more hard-disks, drives, and servers. Cloud Computing and Storage has simplified this by providing an unending expanse of space for you to store, retrieve, manipulate, and do as you please with your data and software infrastructure. 

The types of Cloud Computing

As mentioned before, Cloud Computing’s ease of access, virtually infinite storage, and decentralized control leading to greater computing power. Although these characteristics are linked to make Cloud Computing, the way these are offered work based on different models of working using Cloud. 

There are two specific types of Cloud Computing or “models” as we term them. The categorization of these types and their subtypes will be clear by the following diagram:


Let’s start off by discussing the various Service Models: 

  • Infrastructure-as-a-Service (IaaS): IaaS offers infrastructure or virtualized machines and system resources to set up and run various user-enabled applications. Consider it to be the virtual equivalent of setting up a data storehouse or an office filled with data servers. A major example of this type of service is the famous Amazon Web Services, the cloud computing wing of Amazon. 
  • Software-as-a-Service (SaaS): SaaS offers proprietary software resources for the user to work on. They manage all the resources and backend of the software while leaving the intended usage to the person or group that has obtained the services on a connected platform. Prominent CRM (Customer Relationship Management) Systems like Salesforce, HubSpot, etc are good examples of this type. 
  • Platform-as-a-Service (PaaS): In this type, PaaS offers web platforms for organizations to run their applications. While the vendor manages all the underlying architecture, you will get to manage your data and the applications that you render and run using the service. Examples include CMS (Content Management Systems) and Data Visualization tools

Now, with  the Service models done, we will take a look at Deployment Models which focus on how these products or programs created are available to the end-users or stakeholders:

  • Private Cloud: As the name suggests, Private Cloud can be used by privatized access offered to few people. It is generally restricted to an organization or even a group of people within an organization. Examples include Inventory Management, Company Financial Statements, and Records
  • Public Cloud: Public Cloud is an anyone-can-use service. It is open to the public and can be viewed by anyone, anywhere, anytime. Public Cloud is much more accessible than Private Cloud but also runs the risk of easy compromise and tampering due to its open availability. Examples include Social Media sites, blogging platforms, etc.
  • Hybrid Cloud: As you might have guessed by the name itself, Hybrid Clouds are a combination of both Private and Public Cloud. They are specifically used for offering data or services that can be availed by the user or stakeholder but at the same time have an interface that can’t be accessed by them at the same time. 

Consider the example of a Data Analytics company. They might put out information that might be needed for the user to view through Public Cloud but might have concealed information as part of their extended research that they would be performing on the data and further parameters. 

Benefits of Cloud Computing

  • Reduced time usage for monitoring and maintenance of infrastructure
  • Easily accessible anywhere, anytime 
  • Costs are essentially reduced due to the easy availability of resources in one common forum
  • Quick working for storage and usability 

How Cloud Computing has made online work easy?

Let’s face it, everything today has become online, right from your shopping cart, to your conversations, to your bill payments to your everyday life events that are being posted on your social media platforms, everything has gone “online”. 

The world is now inundated with data with billions and trillions of bytes of data lying unused. But where is all this data present, you guessed it right, it’s all on the cloud, not on Earth, at least it is, virtually. 

There are parent servers that hold the data, but the retrieval of this data can be done anywhere and not only in those parent servers, all you need is your device(s) and a stable Internet connection and you are on Cloud Nine (well, not literally, but that’s how good it is). 

The Business Impact of Cloud Computing 

There is no debating the fact that Cloud Computing has become one of the most sought-after techniques of the cyber age. According to a recent report, across multiple domains, vendors, and workflows, Cyber Security in total generated a revenue of more than US$150 billion. 

Another report from the IDC states that by 2023, companies across the world would’ve spent more than US$500 billion on public cloud services. Currently, there are reportedly 91% of companies that utilized public cloud services, 72% that use private clouds, and 69% that use hybrid cloud services. As an industry domain, its CAGR (Compound Annual Growth Rate) is expected to be at 23.6%. 

In India, public cloud expenditures and management by CSPs provide over 66% of the entire Cloud Market share. 

Careers in Cloud Computing: What is there for you?

We have nicely made it to the part which influences most of our readers. For the people who feel pumped up in learning more through our blogs, we are here to give you an idea about careers and job opportunities in the field of Cloud Computing, Management, and Research. 

There are primarily a few lucrative career opportunities like:

  1. Systems Engineer
  2. Cloud Network Architect 
  3. Software Engineer
  4. Data Engineer
  5. DevOps Engineer

As part of being in the domain of Cloud Computing, you need to be multi-skilled and multi-disciplinary. 

According to Glassdoor, an entry-level professional in the field of Cloud Computing is offered a base salary in the range of ₹3.5-5 Lacs per annum. This of course increases with experience and seniority. 

The highest level of pay is estimated to be about ₹14.5 Lacs per annum for an engineer. So you can expect it to increase even further when it comes to managerial positions. 

Some of the skills required to be a professional in Cloud Computing are: 

  • Knowledge of Cloud Networks and Handling 
  • Awareness of the various practices of Information Security 
  • Knowledge of software like Linux
  • Knowledge and experience in handling Data through Database management tools like MySQL etc 
  • Knowledge of web applications 

All-in-all, Cloud Computing like every other field is in great demand due to its capability for offering a faster and more affordable equivalent to computing. The full potential of Cloud Computing is yet to be unearthed and there is a lot more to be researched in the field. 

Big companies like Amazon and Microsoft have invested billions of dollars into researching and creating their state-of-the-art Cloud Computing software and servers that are now being used by other firms. 

Hence if there is a better time to learn, grow, and gain success in the Cloud Computing sector, the time is now.
