How to use this tool
Estimate replicas, CPU, memory and outbound traffic from application demand. Use the calculator to establish an initial capacity planning hypothesis.
Worked example
Demand of 1,000 requests per second with a measured capacity of 100 requests per second per instance requires at least 10 instances before headroom and redundancy.
Interpreting the result
Validate the plan with load tests. External dependencies, databases, warm-up and software scalability can limit the benefit of additional replicas.
