The Enterprise support plan provides a technical account manager (TAM) and full use of Trusted Advisor, offering proactive guidance and comprehensive access to all checks. This plan is designed for large-scale, mission-critical workloads. The WGU Cloud Deployment and Operations Study Guide (Section 6.4, AWS Support Plans) states, 'The Enterprise support plan includes a dedicated Technical Account Manager and full Trusted Advisor access, providing 24/7 support and proactive optimization recommendations.' Developer, Standard, and Business plans offer limited or no TAM support and partial Trusted Advisor access.
