The company has AWS Enterprise Support and expects a large traffic increase to its website hosted on Amazon EC2 in two months. What should the company do to evaluate readiness for the launch?

Engaging AWS Infrastructure Event Management (IEM) support is the correct action. IEM is a paid offering available to Enterprise Support customers, designed to help prepare for and execute large-scale events like significant website launches. It provides architectural guidance, best practices, and real-time support during the event to ensure operational readiness and minimize risks. Replacing EC2 instances with AWS Lambda functions is a re-architecting decision that is not directly related to evaluating readiness for an upcoming traffic increase on existing EC2 infrastructure. While Lambda can be scalable, it's a different compute model. Submitting a request through AWS Marketplace to monitor the event is incorrect because AWS Marketplace is for finding and deploying third-party software, not for AWS support services. Reviewing coverage reports in the AWS Cost Management console focuses on cost optimization and resource utilization from a financial perspective, not operational readiness for a high-traffic event.
