Cloud Computing
Cloud computing is a service delivery model that provides on-demand access to a shared pool of computing resources over the internet, such as servers, storage, networking, and analytics services.
Key concepts
Scalability: The ability to scale, so allocate and deallocate resources at any time.
Elasticity: The ability to scale dynamically.
Agility: The ability to react fast (scale quickly).
Fault Tolerance: The ability to maintain system uptime while physical and service component failures happen.
Disaster Recovery: The process and design principle which allows a system to recover from natural or human-induced disasters.
High Availability: The agreed level of operational uptime for the system.
It is a simple calculation of system uptime versus the whole lifetime of the system
availability = uptime / (uptime + downtime)
