An ecommerce company plans to move its data center workload to the AWS Cloud to support highly dynamic usage patterns. Which benefits make the AWS Cloud cost-effective for the migration of this type o

Reliability is a benefit of the cloud (fault tolerance, data recovery), but it is not primarily a *cost-effective* benefit for *dynamic usage patterns* in the same way elasticity and pay-as-you-go are.

Security is a fundamental benefit of AWS (shared responsibility model, various services), but it's not a primary *cost-effective* benefit specifically for *dynamic usage patterns*.

Elasticity allows the AWS Cloud to automatically scale computing resources up or down rapidly to meet fluctuating demand, ensuring optimal resource utilization and preventing over-provisioning which leads to significant cost savings for dynamic workloads.

The 'pay-as-you-go' resource model means customers only pay for the specific resources they use and for the duration they use them, eliminating the need for large upfront capital expenditures and reducing costs for variable workloads.

High availability is an important benefit of AWS (e.g., Multi-AZ deployments) ensuring uptime, but like reliability, it's not the core *cost-effective* benefit derived from *dynamic usage patterns* compared to elasticity and pay-as-you-go.
