What is Cloud Computing?
Cloud computing is a model of delivering computing services over the internet, where resources such as servers, storage, and applications are provided as a service to users on-demand. It allows users to access and use computing resources without managing and maintaining physical hardware.
Three Main Types of Cloud Services
- Infrastructure as a Service (IaaS): provides virtualized computing resources, such as servers, storage, and networking. Examples: Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP).
- Platform as a Service (PaaS): provides a complete platform for developing, running, and managing applications, including tools, libraries, and infrastructure. Examples: Heroku, Google App Engine, AWS Elastic Beanstalk.
- Software as a Service (SaaS): provides software applications over the internet, eliminating the need for local installation and maintenance. Examples: Microsoft Office 365, Salesforce, Dropbox.
