What is one method to avoid overload when opening a portal for a short time with many requests?

Using a Content Delivery Network (CDN) to create waiting rooms is a highly effective method for managing high traffic volume, particularly when a portal is opened for a limited time and may receive an influx of requests. CDNs help to distribute the load across multiple servers, ensuring that no single server becomes overwhelmed. By implementing waiting rooms, users can be queued until the system is ready to handle their requests, which prevents crashes and maintains performance stability.

The incorporation of a waiting room allows organizations to smooth out surges in traffic, giving them the opportunity to manage user access intentionally. This not only enhances the user experience by regulating access during peak times but also safeguards against overload situations that could lead to service interruptions.

Although the other methods listed may contribute to overall performance optimization or issue mitigation, they do not directly address the challenge of managing sudden and excessive incoming requests as effectively as utilizing a CDN to create waiting rooms.
