Cloud Computing Basics

Cloud computing is a model for delivering computing services over the internet, where resources such as servers, storage, databases, software, and applications are provided as a service to users on-demand.

Key Characteristics of Cloud Computing

• On-Demand Self-Service**: Users can provision and de-provision resources as needed, without requiring human intervention.
• Broad Network Access**: Resources are accessible over the internet, or a private network, from any device, anywhere in the world.

• Resource Pooling**: Resources are pooled together to provide a multi-tenant environment, where resources can be dynamically allocated and re-allocated based on demand.

• Rapid Elasticity**: Resources can be quickly scaled up or down to match changing business needs.

• Metered Billing**: Users only pay for the resources they use, rather than having to purchase and maintain their own hardware and software.

Types of Cloud Computing

• Public Cloud**: A public cloud is a cloud computing service that is open to the general public and is owned by a third-party provider.
• Private Cloud**: A private cloud is a cloud computing service that is dedicated to a single organization and is not accessible to the general public.
• Hybrid Cloud**: A hybrid cloud is a cloud computing service that combines public and private clouds, allowing data and applications to be shared between them.

Cloud Computing Service Models

• IaaS (Infrastructure as a Service)**: Provides virtualized computing resources, such as servers, storage, and networking.
• PaaS (Platform as a Service)**: Provides a complete platform for developing, running, and managing applications, including tools, libraries, and infrastructure.
• SaaS (Software as a Service)**: Provides software applications over the internet, eliminating the need for users to install, configure, and maintain software on their own devices.

Benefits of Cloud Computing

• Scalability**: Cloud computing resources can be quickly scaled up or down to match changing business needs.
• Cost-Effectiveness**: Users only pay for the resources they use, rather than having to purchase and maintain their own hardware and software.
• Flexibility**: Cloud computing resources can be accessed from anywhere, at any time, from any device with an internet connection.
• Reliability**: Cloud computing resources are typically more reliable than on-premise resources, with built-in redundancy and failover capabilities.
