What is Cloud Computing – Basics for Beginners

What is cloud computing? Learn everything about cloud computing, starting with the basics, all the way to types, management, and more.

Today’s business world is more digital than ever before, and cloud computing is a big part of that. Cloud computing is the ability to access information and applications over the Internet.

This means that instead of having a program installed on your computer, you can access or store it on a remote server. Cloud computing has many business benefits, including cost savings, scalability, and flexibility.

If you need to know the basics of cloud computing, you’ve come to the right place. In this article, we’ll cover everything you need to know about cloud computing, from what it is exactly to how to manage it (aws support plans). Keep reading to get started!

What is cloud computing?

In the most basic terms, cloud computing is the ability to access information and applications over the Internet. This means that instead of having a program installed on your computer, you can access or store it on a remote server.

Think of it like this: instead of having Microsoft Word installed on your computer, you can access it through the cloud. The cloud is a fancy way of saying “the Internet”, and cloud computing simply means using the Internet to access, store, and manage information and applications.

How does cloud computing work?

Let’s go into a little more detail about how cloud computing works. When you use a cloud computing service, like Google Drive, you’re accessing information and applications stored on remote servers.

These servers are usually located in data centers and are maintained by a cloud provider, like Amazon Web Services (AWS). AWS is one of the most popular cloud providers, and it’s used by some of the biggest companies in the world, like Netflix and Airbnb.

When you access information or applications through the cloud, you do it over the Internet. This means that you can access your data from anywhere in the world, as long as you have an Internet connection.

What is Cloud Computing: Categories

Typically, cloud computing services are divided into three categories:

Infrastructure as a Service (IaaS)

One of the most popular cloud computing services is Infrastructure as a Service, or IaaS. With IaaS, you can rent remote servers from a cloud provider to store your data or run your applications. Amazon Web Services (AWS) is one of the most popular IaaS providers.

When you use AWS, you’re renting remote servers from Amazon. This means you don’t have to worry about maintaining physical servers, which can be costly and time-consuming.

IaaS is a great option for businesses that want the flexibility and scalability of the cloud without the responsibility of maintaining infrastructure. Check out aws support plans to know which plan is right for you.

Platform as a Service (PaaS)

Unlike IaaS, with Platform as a Service or PaaS, you’re not just renting remote servers. You’re also renting the software and tools needed to develop and run your applications.

One of the most popular PaaS providers is Heroku, often used by startups and small businesses. Heroku takes care of all the infrastructure and server management, so you can focus on developing your application.

PaaS is a great option for businesses that want to develop and launch an application quickly, without having to worry about the infrastructure. Of course, this convenience comes at a price, and PaaS can be more expensive than other cloud computing services.

Software as a Service (SaaS)

Software as a Service or SaaS is one of the most popular cloud computing services. With SaaS, you’re renting software that’s hosted on remote servers. You don’t have to install or maintain the software on your servers.

Some popular SaaS applications include Google Suite, Microsoft Office 365, and Salesforce. SaaS is a great option for businesses that want to use cloud-based software without worrying about maintenance or upkeep.

It differs from IaaS and PaaS in that you’re not just renting servers or software; you’re also renting the tools like databases and storage.

What are the types of cloud computing?

There are four main types of cloud computing: public, private, hybrid, and multi-cloud. Let’s take a look at each one in turn.

Public cloud:

A cloud provider provides public cloud services, and they’re available to anyone who wants to use them. This is the most popular type of cloud computing type and is often the most cost-effective option.

Private cloud:

A cloud provider provides private cloud services, but they’re only available to a specific organization. This type of cloud is often used by businesses with sensitive data or requiring a high level of security. For example, banks and healthcare organizations often use private cloud.

Hybrid cloud:

A hybrid cloud is a mix of public and private clouds. It’s often used by businesses that want the flexibility of the public cloud, but with the security of the private cloud. Often, data is stored in the private cloud, while applications are run in the public cloud.


Multi-cloud is a mix of two or more cloud providers. It’s typically used by businesses that want to avoid vendor lock-in. By using multiple cloud providers, businesses can choose the best provider for each individual workload.

What is Cloud Computing: Management

Now that we’ve covered the basics of cloud computing, let’s look at how it’s managed. Typically, cloud computing services are managed by a cloud provider, like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform.

These cloud providers are responsible for maintaining the servers and infrastructure that power their cloud services. They also handle security, updates, and other management tasks.

However, some businesses choose to manage their cloud services in-house. This can be a good option for businesses with the resources and expertise to do so.

But it’s important to note that managing cloud services in-house can be a costly and time-consuming endeavor. It’s also important to have the right tools and processes to do it effectively.

What is Cloud Computing: Security

Security is one of the most important considerations when it comes to cloud computing. After all, your data and applications are stored on remote servers, which means they’re potentially vulnerable to attack.

Fortunately, cloud providers take security seriously, and they have a variety of measures in place to protect your data, such as:

  • Encryption
  • Firewalls
  • Access control
  • Intrusion detection and prevention

However, it’s important to note that cloud security is a shared responsibility. This means that you, as the customer, also have a role to play in securing your data. For example, you need to make sure that your passwords are strong and that you’re using two-factor authentication.

You also need to be aware of the potential security risks when using cloud services. For example, cloud services can be a target for denial of service attacks.

To protect against these attacks, you need to have a plan in place to keep your data and applications safe.

Do you need cloud computing?

Now that you know the basics of cloud computing, you might be wondering if it’s right for your business. The answer to this question depends on a variety of factors, such as your budget, your technical expertise, and your data storage needs.

If you’re not sure whether cloud computing is right for you, we recommend consulting with a cloud expert. They can assess your needs and help you determine whether cloud computing is a good fit for your business.


In the ever-evolving world of business, cloud computing is often an essential tool. It allows businesses to be more agile, efficient, and cost-effective.

If you’re not already using cloud computing, we recommend taking the time to learn more about it. And if you’re considering moving to the cloud, don’t forget to consult with a cloud expert to get started.
