Study Notes

Cloud Computing

Definition: Cloud computing provides on-demand access to shared computer resources (networks, servers, storage, applications, services) over the internet. These resources can be rapidly provisioned and released with minimal management effort.
NIST: The US National Institute of Standards and Technology defines cloud computing as a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources.

Essential Characteristics

On-Demand Self-Service: Users can access resources automatically without needing human interaction.
Broad Network Access: Services are accessible over the network via standard mechanisms, suitable for various devices.
Resource Pooling: Cloud providers pool their resources to serve multiple customers, dynamically assigning resources based on demand.
Rapid Elasticity: Services can be quickly scaled up or down as required.

Advantages of Cloud Computing

Lower Computer Costs: Users can use less expensive computers with less processing power and storage, as applications run in the cloud.
Improved Performance: With less burden on local computers, overall system performance improves.
Centralized Management: Cloud providers manage the infrastructure, simplifying tasks for users.
