A company is evaluating the advantages of migrating to the AWS Cloud. Which of the following scenarios BEST illustrates the combined benefits of high availability, elasticity, and agility in the AWS Cloud?
Purchasing excess on-premises server capacity in anticipation of a potential future traffic increase.
Using a single EC2 instance that can be resized manually to accommodate an increase in web traffic.
Deploying an application across two on-premises data centers for disaster recovery purposes.
Utilizing Auto Scaling to launch instances in multiple Availability Zones, adapting to traffic surges while enabling rapid deployment of new features.
The correct option is the best choice because it encompasses the principles of high availability (multiple Availability Zones), elasticity (automatically adding resources via Auto Scaling to meet demand), and agility (enabling rapid deployment).
The option describing a single, manually resized EC2 instance addresses a form of scalability but lacks both the automatic response of elasticity and the fault tolerance of high availability.
The option describing deployment across two on-premises data centers refers to high availability but is not an AWS Cloud solution.
The option about purchasing excess on-premises capacity is a traditional approach that cloud elasticity is designed to replace.
