What does enabling Auto Scaling do for your cloud environment?

Enabling Auto Scaling in a cloud environment adjusts resources automatically based on demand, which is crucial for optimizing performance and cost efficiency. This feature allows the system to monitor the usage of resources, such as compute instances, and automatically scale up or down according to the current load and traffic patterns. For example, during peak usage times when demand increases, Auto Scaling can launch additional instances to handle the load. Conversely, during periods of low demand, it can terminate instances to reduce costs. This capability ensures that users receive a consistent level of service without over-provisioning resources, which can lead to unnecessary expenses, or under-provisioning, which can degrade application performance.

The other options do not reflect the primary functionality of Auto Scaling. Limiting the number of users does not relate to resource management within the cloud; stabilizing network connections is more about network configuration and quality of service rather than resource scaling; and increasing physical security of data centers pertains to infrastructure security rather than the dynamic management of computational resources.
