Cloud Computing Meaning: Understanding the Basics

Cloud computing is a buzzword that has been around for a while. Many people have heard of it, but few understand what it really means. In this article, we’ll explain what cloud computing is, how it works, and why it’s important.

What is Cloud Computing?

Cloud computing is the delivery of computing services over the internet. It allows users to access a range of resources, such as software, databases, and storage, without having to rely on their own hardware and infrastructure.

Essentially, cloud computing is a way of outsourcing IT services to a third-party provider. This provider hosts the services and delivers them to the user via the internet. This means that the user can access the services from anywhere, at any time, as long as they have an internet connection.

How Does Cloud Computing Work?

Cloud computing works by dividing resources into three main categories: infrastructure, platform, and software. These categories are sometimes referred to as the “cloud stack”.

Infrastructure as a Service (IaaS) provides users with access to computing resources such as virtual machines, storage, and networking. Platform as a Service (PaaS) provides users with a platform for developing and deploying applications, while Software as a Service (SaaS) provides users with access to software applications over the internet.

Cloud computing providers typically offer a range of services across these categories, allowing users to pick and choose the resources they need to run their applications.

Why is Cloud Computing Important?

Cloud computing offers a number of benefits that make it an important technology for businesses of all sizes. Here are just a few:

  • Scalability: Cloud computing allows businesses to scale up or down their IT resources as needed, without having to invest in expensive hardware.
  • Flexibility: Cloud computing allows businesses to access their IT resources from anywhere, as long as they have an internet connection.
  • Cost Savings: Cloud computing can save businesses money on hardware, software, and IT staff.
  • Reliability: Cloud computing providers offer high levels of uptime and reliability, ensuring that businesses can access their IT resources when they need them.

Types of Cloud Computing

There are three main types of cloud computing: public, private, and hybrid.

Public cloud computing refers to services that are provided by third-party providers and accessed by multiple organizations over the internet. Private cloud computing, on the other hand, refers to services that are hosted on a private network and accessed only by a single organization. Hybrid cloud computing combines elements of both public and private cloud computing.

Examples of Cloud Computing

There are many examples of cloud computing in use today. Here are just a few:

  • Email: Services such as Gmail and are examples of cloud-based email services.
  • File Storage: Services such as Dropbox and Google Drive allow users to store and access files over the internet.
  • CRM: Customer Relationship Management (CRM) services such as Salesforce are delivered via the cloud.
  • HR: Human Resources (HR) services such as Workday are also delivered via the cloud.


Cloud computing is an important technology that has revolutionized the way businesses access and manage their IT resources. By outsourcing IT services to third-party providers, businesses can save money, increase flexibility, and improve reliability. As cloud computing continues to evolve, we can expect to see even more exciting developments in the years to come.
