The top-tier support plan offers comprehensive benefits including 24/7 access to experienced engineers, a dedicated professional to provide management and proactive monitoring, and specialized support for large-scale event operations. The next tier down provides around-the-clock support but lacks personalized management and assistance for large-scale events. The third tier is more developer-focused and does not provide the level of service required for managing critical operations. The basic tier offers foundational services but without dedicated professionals or event support.
