Which feature allows AEM as a Cloud Service to manage sudden increases in traffic?

The feature that enables AEM as a Cloud Service to effectively manage sudden increases in traffic is auto scaling. This functionality allows the system to automatically adjust the amount of computing resources it uses based on the current demand. When there's a spike in traffic, such as during a major marketing campaign or product launch, auto scaling provisions additional resources to handle the increased load. This ensures that the application remains responsive and performs well even under stress.

Auto scaling is essential for cloud applications like AEM because it provides flexibility and helps maintain performance without manual intervention. In contrast, manual resource allocation requires human input and does not react quickly to changing conditions, making it less efficient in dynamic environments. Static resource management implies that resources are fixed and cannot adjust to fluctuations in demand, which can lead to performance issues during peak traffic. Traffic forecasting, while useful for planning and preparing for potential spikes, does not directly address the immediate need for increased resources during a surge.
