What is Cloud Computing?

What is Cloud Computing?
Cloud computing is the delivery of computing services over the internet ("the cloud"). These services include storage, processing power, and applications, which can be accessed on-demand and without direct active management by users.
Key Concepts
Service Models:
IaaS (Infrastructure as a Service): Virtualized computing resources over the internet (e.g., AWS EC2, Google Compute Engine).
PaaS (Platform as a Service): Provides a platform allowing customers to develop, run, and manage applications (e.g., Google App Engine, Microsoft Azure).
SaaS (Software as a Service): Software distribution model in which applications are hosted by a service provider and made available to customers over the internet (e.g., Google Workspace, Salesforce).
Deployment Models:
Public Cloud: Services are delivered over the public internet and shared across multiple organizations.
Private Cloud: Services are maintained on a private network for a single organization.
Hybrid Cloud: Combines public and private clouds, allowing data and applications to be shared between them.
Key Features:
Scalability: Resources can be scaled up or down based on demand.
Flexibility: Users can access services and applications from any location with internet access.
Cost Efficiency: Pay-as-you-go pricing models reduce the need for heavy upfront investments in hardware.
Benefits of Cloud Computing
Accessibility: Access services from anywhere, anytime.
Collaboration: Easy sharing and collaboration tools.
Automatic Updates: Providers manage software updates and security.
Disaster Recovery: Enhanced backup and recovery solutions.
Conclusion
Cloud computing has transformed how businesses operate by providing flexible, scalable, and cost-effective solutions. As technology evolves, its adoption continues to grow across various industries.
