Explanation

Correct Answers:

• B. Deploy globally in minutes - AWS allows rapid global deployment through its worldwide infrastructure of Availability Zones and Regions
• D. Take advantage of economies of scale - AWS leverages massive scale to offer lower prices and better services to customers

Why other options are incorrect:

• A. Trade variable expenses for capital expenses - This is actually the opposite of a cloud benefit. In the cloud, you trade capital expenses (CapEx) for variable expenses (OpEx)
• C. Plan capacity in advance of deployments - One of the key benefits of cloud computing is that you don't need to plan capacity in advance; you can scale on demand
• E. Reduce dependencies on network connectivity - Cloud computing actually increases dependency on network connectivity, not reduces it

Key AWS Cloud Benefits:

• Global deployment speed - AWS has infrastructure worldwide that enables rapid deployment
• Economies of scale - AWS's massive infrastructure allows for cost savings passed to customers
• Pay-as-you-go pricing - Convert CapEx to OpEx
• Elastic scalability - Scale up or down based on demand without capacity planning
• High availability - Built-in redundancy across multiple Availability Zones
