Cloud

The term “cloud” in the context of technology refers to a system of servers that store data and applications on the Internet rather than on a personal computer or local server. This allows data and applications to be accessed and used from any device and any geolocation where there is an Internet connection.

Key benefits

• Scalability. Cloud services can be scaled up or down depending on user needs.
• Cost-effectiveness. Users only pay for the resources they use, so there is no need for capital expenditure.
• Accessibility. Data and applications in the cloud can be accessed from anywhere, on any device and at any time.

Main types of cloud services

Infrastructure as a Service (IaaS). Provides computing resources over the Internet. Example: Amazon Web Services (AWS).

Platform as a Service (PaaS). Provides a platform that allows customers to develop, run, and manage applications. Example: Microsoft Azure.

Software as a Service (SaaS). Providing software applications over the Internet on a subscription basis. Example: Google Workspace.

Cloud computing versus traditional computing

Cloud computing. Data and applications are stored on remote servers in data centers. Provides flexibility, scalability, and business savings.

Traditional computing. Data and applications are stored on local servers or PCs. Does not have the flexibility and scalability of the cloud.
