Define Cloud Computing

Cloud computing has become a buzzword in recent years, but what does it really mean? In this article, we will define cloud computing in plain English and explore its benefits and drawbacks.

What is Cloud Computing?

Cloud computing refers to the delivery of computing services, including servers, storage, databases, software, analytics, and more, over the internet. Businesses and individuals can access these services on demand, without having to own or maintain their own computing infrastructure.

Cloud computing can be divided into three main categories:

  • Infrastructure as a Service (IaaS)
  • Platform as a Service (PaaS)
  • Software as a Service (SaaS)

IaaS provides virtualized computing resources, such as servers, storage, and networking, that can be accessed over the internet. PaaS provides a platform for developers to build, test, and deploy applications without having to manage the underlying infrastructure. SaaS provides access to software applications that are hosted in the cloud and can be accessed over the internet.

Benefits of Cloud Computing

Cloud computing offers several benefits, including:

  • Cost savings – Cloud computing eliminates the need for businesses to invest in and maintain their own computing infrastructure, which can be expensive.
  • Scalability – Cloud computing allows businesses to scale their computing resources up or down on demand, depending on their needs.
  • Flexibility – Cloud computing allows businesses to access computing resources from anywhere, at any time, using any device with an internet connection.
  • Reliability – Cloud computing providers typically offer high levels of uptime and reliability, which can be difficult for businesses to achieve on their own.

Drawbacks of Cloud Computing

While cloud computing offers many benefits, it also has some drawbacks, including:

  • Security – Cloud computing introduces new security risks, such as data breaches and unauthorized access, that businesses must manage.
  • Dependency – Cloud computing requires businesses to rely on third-party providers for their computing infrastructure, which can create a dependency that can be difficult to manage.
  • Customization – Cloud computing providers may not offer the same level of customization and control over computing resources as businesses would have with their own infrastructure.

Examples of Cloud Computing

Cloud computing is used by businesses and individuals in a wide range of industries. Some examples of cloud computing include:

  • Netflix – Netflix uses cloud computing to stream movies and TV shows to millions of users around the world.
  • Salesforce – Salesforce provides cloud-based customer relationship management (CRM) software to businesses of all sizes.
  • Dropbox – Dropbox allows individuals and businesses to store and share files in the cloud.


Cloud computing is a powerful technology that offers many benefits, including cost savings, scalability, flexibility, and reliability. However, it also introduces new security risks and a dependency on third-party providers. As more businesses and individuals move their computing resources to the cloud, it is important to understand the benefits and drawbacks of this technology and to manage the risks accordingly.
