Understanding Cloud Computing: What it is and How it Works 1

What is Cloud Computing?

Cloud computing provides on-demand access to computing services such as storage, databases, software, and analytics over the internet, allowing companies to operate efficiently without incurring the cost of maintaining their own infrastructure. The term “cloud” computing originated from the cloud symbol often used to represent the internet in flowcharts and diagrams. Instead of keeping the data on a personal computer or local server, cloud computing stores it on remote resources accessed through the internet.

Types of Cloud Computing

There are three different types of cloud computing:

  • SaaS (Software as a Service): provides on-demand software applications hosted on the cloud.
  • PaaS (Platform as a Service): offers a platform for software creation and deployment in the cloud.
  • IaaS (Infrastructure as a Service): offers virtualized computing resources, such as servers, storage, and networking in the cloud.
  • The most popular type of cloud computing is SaaS since it provides a complete software solution for various business needs like accounting, customer relationship management, and human resources without the need for local installations.

    The Advantages of Cloud Computing

    Cloud computing offers several distinct advantages for companies, ranging from savings in resources and costs to increased scalability and flexibility.

    Some of the advantages of cloud computing include:

  • No need for physical hardware: a virtualized cloud infrastructure means there is no need for any local hardware equipment, thereby saving resources and costs.
  • Cost-effective: as companies only pay for the resources used, cloud computing can be more cost-effective than hosting an on-premise server.
  • Scalability: cloud computing can scale up or down depending on the needs of the company, making it an ideal solution for businesses with varying resource needs.
  • Increased mobility: cloud computing allows for easy access to software and files from anywhere in the world with an internet connection, increasing flexibility and mobility for remote workers.
  • Security Concerns in Cloud Computing

    While cloud computing has become immensely popular in recent years, there are several concerns about the security of cloud-based data. Data breaches and unauthorized access to sensitive information are the most common concerns. However, using the right kind of cloud provider can reduce these risks. A reputable cloud computing service provider ensures that your data is stored in a secure environment with constant monitoring and backups.


    Cloud computing has revolutionized the way businesses operate by shifting the focus from physical resources to virtual resources. Whether it’s SaaS, PaaS, or IaaS, cloud computing offers many advantages, such as cost savings, scalability and flexibility, mobility, and easy access to software and files. Security concerns are genuine, but they can be mitigated by choosing reputable cloud providers.
