Overview of Cloud Computing
Cloud computing is a technology that enables on-demand access to computing resources such as servers, storage, databases, networking, software, and analytics over the internet. It provides flexibility, scalability, and cost-effectiveness for businesses of all sizes.
Cloud computing allows users to access IT resources without maintaining physical hardware. It offers three primary service models—Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS)—each catering to different business needs.
Key Benefits of Cloud Computing
- Scalability: Easily scale resources up or down based on demand.
- Cost Efficiency: Reduces the need for costly on-premises infrastructure.
- Flexibility: Access services from anywhere with an internet connection.
- Security: Cloud providers offer advanced security features and compliance standards.
- Automatic Updates: Ensures software and hardware are always up-to-date.
- Disaster Recovery: Cloud-based backup solutions provide better business continuity.
Cloud computing enables businesses to be more agile and efficient.

Cloud computing is categorized into three major types:
Public Cloud
Services provided by third-party cloud providers such as AWS, Azure, and Google Cloud, offering scalability and cost efficiency.
Private Cloud
