Key cloud concepts

• High availability - Keep services up and running for long periods(with very little downtime)
• Scalability - Increase or decrease resources for any given workload
• Elasticity - Resources are added or removed automatically to meet future needs
• Agility - React quickly
• Fault tolerance - Redundancy(backup component)
• Disaster recovery - From event which has taken down a cloud service
• Global reach
• Customer latency capabilities
• Predictive cost considerations
• Technical skill requirements and considerations
• Increased productivity
• Security - Protect from potential threats

Economies of scale - Ability to reduce costs and gain efficiency
