Before you can calculate the ECS cluster capacity, you need to have a clear understanding of which resources affect capacity and how you can calculate the current capacity for each resource. Once you have defined this for each individual resource, you then need to apply an aggregate calculation across all resources, which will result in a final calculation of the current capacity.
Calculating capacity can appear to be quite a daunting task, especially when you consider the different types of resources and how they behave:
- CPU: This is the simplest resource you can work with, as each CPU reservation simply deducts from the available CPU capacity of the cluster.
- Memory:Â Calculating the current capacity of the cluster based upon memory is identical to CPU in that a memory reservation deducts from the available memory capacity of the...
