Cloud computing is a revolutionary model in information technology that delivers computing services over the internet. It allows organizations and users to access storage, databases, servers, networking, software, and analytics remotely, rather than relying on local hardware or physical infrastructure. This on-demand availability of resources promotes scalability, flexibility, and cost-efficiency.
Cloud computing refers to the use of remote servers hosted on the internet to manage, store, and process data, instead of using local servers or personal computers. It is an umbrella term encompassing different types of cloud services, such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
IaaS provides virtualized physical computing resources over the internet. Users can rent virtual machines, storage, and networks without maintaining physical hardware.
Examples: Amazon Web Services (AWS), Microsoft Azure, Google Compute Engine
PaaS offers a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure.
Examples: Heroku, Google App Engine, AWS Elastic Beanstalk
SaaS delivers software applications over the internet, on a subscription basis. It removes the need for installations and maintenance.
Examples: Google Workspace, Salesforce, Microsoft Office 365
Also known as serverless computing, FaaS allows developers to execute code in response to events without managing servers.
Examples: AWS Lambda, Azure Functions
