/kind feature

Describe the solution you'd like For every reconciliation, CAPZ will completely rebuild the cluster Authorizer and with it, cause a request to Azure Active Directory to procure a new JWT which will them be used to Authenticate to Azure. You can see the POST in the Jaeger output below.

capz-auth-overhead

Azure Active Directory generally responds in about 80ms - 200ms, but this is overhead for every reconcile cycle. It adds up. Also, it's not very friendly to Azure Active Directory.

I think we can use the work in https://github.com/kubernetes-sigs/cluster-api-provider-azure/pull/1067, specifically, the Authorizer.Hash() and the time to live least recently used cache to create a safe and efficient mechanism to reuse Authorizers across reconcile cycles.

@nojnhuh - Do you think this is still valid after all the refactoring we've done or not sure without more investigation?

nojnhuh commented 1 year ago

I'm not aware of anything done recently that addresses this.

dtzar commented 1 year ago

If this still happens with main branch today assuming workload identity, then something we should prioritize.
