EC2 Auto Scaling acts as a buffer for your instances, automatically adding new instances when needed and terminating them when no longer required.
You can configure a group of instances, with a set minimum capacity that will always be running, while additional instances scale up or down based on demand.
|
You can specify the desired number of AWS EC2 instances in the scaling group. However, if not specified, the desired capacity will default to the minimum capacity. |
The final configuration is Maximum Capacity, where you define the maximum number of instances that can be utilized.
|
Auto Scaling groups provide a dynamic environment where you define the minimum capacity, desired number of instances, and maximum capacity. The group operates within these settings, ensuring a predictable and cost-effective architecture. |
