• Security - AWS maintains secure facilities and offers various means of securing cloud resources
• Reliability - ensures data integrity and performance consistency
• High Availability – systems operate continuously without failure for a long time, avoiding loss of service
• Elasticity – resources grow and shrink based on demand without the need to provision ahead of time
• Agility – fast access to services and increased speed to market
• Pay-as-you-go pricing - only pay for resources used instead of making large upfront investment
• Scalability – resources can scale up or down to handle workloads of virtually any size
• Global Reach – can deploy in regions and zones around the world at the click of a button
• Economy of scale – volume discounts are passed on to customers, offering lower prices
