When I was a kid, I loved looking at clouds and imagining funny shapes. Sometimes, I even wondered if someone was up there! Now that I’m an adult, I still ask, “What’s in the cloud?”
When we talk about “the cloud” in technology, we’re not referring to those fluffy clouds in the sky. Instead, the cloud represents a network of remote servers connected by wires and cables.
In the past, businesses used large servers in their offices to store data, which took up a lot of space. While that still works, imagine having powerful software, lots of storage, and computing resources, without needing a room full of machines. That sounds great! Having an organized space can make you feel calm and focused, and that’s what cloud computing offers.
Today, we can store our pictures, videos, emails, and data in the cloud instead of using boxes and drives like we used to. Major cloud providers like AWS, Microsoft Azure, and Google Cloud allow us to store and access our data from anywhere.
In this article, I’ll explain cloud computing, how it works, and why it’s important for businesses and everyday people.

What is Cloud Computing and How Does It Work?
Cloud computing is a process where technology services like storage, databases, computing power, and software are delivered over the Internet. In simple terms, it means using the internet to access storage, apps, or tools on powerful computers that aren’t in your organization. Instead of needing large storage or high-powered equipment yourself, you can connect online to store files, watch movies, or work on projects.
In cloud computing, the three basic functions are:
-
Storage: This lets you save and keep your data online, like using Google Drive or Dropbox for your files.
-
Computing: This provides the power to process tasks, similar to how a computer’s CPU works. It helps run applications smoothly.
-
Database: This stores organized data. For example, services like Amazon RDS or Google Cloud SQL manage information for apps.
Who Are the Leading Cloud Providers?
Cloud providers offer the infrastructure and services needed to deploy and scale applications.
Big companies like Amazon Web Service (AWS), Google (Google Cloud), and Microsoft (Azure) are leading providers in the cloud industry.
Below is a summary of each provider:
-
Amazon Web Services (AWS): AWS is a leading cloud provider, offering a wide range of services including cloud storage (S3), databases (RDS), and machine learning tools. It’s known for its scalability, flexibility, and reliability, making it a popular choice for developers and businesses.
-
Microsoft (Azure): Microsoft has been around for 45 years, and over time, they’ve adapted their software like Microsoft Office and Windows, seamlessly integrating these services with the cloud. They provide services like Azure Blob Storage and Azure SQL Database. As a result, Microsoft is considered one of the top cloud providers.
-
Google (Google Cloud): Google Cloud offers powerful services like Google BigQuery for data analytics and Google Anthos for managing hybrid applications. Google Cloud is known for its speed and reliability, and provides tools for storage, computing, and database management, making it a solid choice for businesses.
All these cloud providers rent out powerful computers to individuals and businesses, allowing you to store files, use apps, or run a business without needing your own servers and equipment.
Types and Models of Cloud Services
Due to the powerful features of cloud services, some companies prefer to control certain parts themselves. This brings us to three types of service control in cloud computing:
-
Infrastructure as a Service (IaaS):
Think of IaaS as renting a computer online. You can practice coding or run a website without buying any hardware. For example, you can rent a powerful server from AWS. With IaaS, you have full control over everything. You can choose the operating system and install the software you need. -
Platform as a Service (PaaS):
PaaS is like having a complete workshop online. It gives you the tools to build and launch projects, like a mobile app. You can create your applications, but the provider handles the servers and storage. This way, you can focus on building your app without worrying about the technical details. -
Software as a Service (SaaS):
SaaS lets you use software directly on the internet. For example, you can write documents using Google Docs, or practice coding with Replit. With SaaS, you have limited control. You can change some settings, but the provider handles everything else, like maintenance and updates.
These options help businesses decide how much control they want over cloud services.
Real-World Uses of Cloud Services
Here are some examples of using cloud services in real life:
-
When you watch Netflix, you’re using the cloud. Netflix keeps movies on its cloud servers and streams them to you online, so there’s no need to download anything.
-
Services like Google Drive and Dropbox let you store files in the cloud instead of on your computer. This way, you can access your files from any device with internet access.
-
With Google Docs, you can create and edit documents in the cloud. You don’t need to install anything on your computer. You can even collaborate with others in real-time.
How Do Developers Use the Cloud?
Cloud services play a key role in development:
-
Cloud services like Amazon Web Service (AWS) and Google Cloud provide development tools, virtual environments, and analytics services which developers can use to test their application.
-
Getting applications online is made easy with services like AWS Amplify, which allow developers to host their apps without writing the backend code.
-
Cloud storage allows developers to easily add extra storage as needed while keeping data safe and accessible from any location.
-
Services like Google TensorFlow and AWS SageMaker offer resources for quickly developing AI and machine learning projects.
Why is Cloud Computing Important?
Cloud computing offers several key benefits:
-
For businesses that want to save money, cloud computing helps cut out expensive hardware and maintenance. You only pay for what you use, like creating virtual servers or storing files.
-
Storing data or files in the cloud can help you easily increase or decrease your resources based on your needs. This flexibility lets businesses adapt quickly to changes—for example, an increase in Black Friday sales or Boxing Day.
-
In the event of a disaster, such as a fire, storing files in the cloud serves as a reliable backup, ensuring that important information is not lost. This is especially beneficial for hospitals and government agencies.
-
Using cloud service enhances collaboration among workers and ease of getting a file since it is remote.
-
Most cloud providers offer fast services, which leads to quicker load times.
-
Cloud services are secure.
What Do You Need to Know to Use the Cloud?
-
To start using the cloud, you should learn basics like virtual machines, storing data, networking, and security.
-
Understand how to back up your data and recover it in case of any issues.
-
Learn how pricing works in the cloud so you can monitor and manage your costs effectively.
-
Most cloud platforms offer tutorials, tools, and ready-made services to make them easier to understand and speed up development.
It can be overwhelming at first, but just start with the basic services, and everything else will fall into place.
Conclusion
In conclusion, cloud computing is changing the way businesses work and how we store and manage data. It offers flexibility, minimizes cost, and leads to easy collaboration, while improving backup and recovery.
As cloud technology continues to grow, it will become even more important for both individuals and businesses. Whether you’re storing personal files or managing a big company, the cloud makes it simpler, safer, and more affordable.
