Technically speaking Scale out is more VM's being provisioned for high demand. Scale UP is more CPU's and Memory etc being added - that is not elasticity since CPU is not hot swappable.

Selected Answer: AB

Answer: AB A. High availability - High availability architecture is designed to minimize downtime by providing redundant systems and components. It ensures that if one region or data center experiences an outage, the workload can failover to another region with minimal interruption. B. Elasticity - Elasticity is the ability to automatically scale resources up or down in response to changing demand. It allows the infrastructure to expand during periods of high utilization and contract when the demand decreases, which helps maintain performance and cost efficiency.
