Which AWS Cloud features will help the company meet this requirement?

Explanations:

Cross-Region workload deployment is not specifically designed to handle seasonal workload increases. It allows for deployment across different geographic regions for redundancy and latency improvements but does not directly address cost-effectiveness or automatic scaling based on workload changes.

Pay-as-you-go pricing is a fundamental feature of AWS that allows companies to pay only for the resources they use. This is cost-effective, especially for handling seasonal workload increases, as it eliminates the need for upfront investments in infrastructure that may be underutilized during off-peak times.

Built-in AWS CloudTrail audit capabilities provide logging and monitoring of AWS account activity but do not directly assist in automatically managing workload increases or optimizing costs. It is more focused on security and compliance than on handling fluctuating workloads.

Auto Scaling policies enable the automatic adjustment of compute resources based on the current demand. This feature is essential for handling seasonal workload increases efficiently and cost-effectively, as it allows the company to scale resources up or down as needed without manual intervention.

Centralized logging is useful for monitoring and troubleshooting but does not directly contribute to managing seasonal workload increases or optimizing costs. It is more focused on operational insights rather than scaling infrastructure in response to demand.
