Why the totals differ
AWS is the lowest-cost option for Keycloak at the extra small tier, landing $73.48 per month below Google Cloud. This spread comes from instance and storage pricing in the default regions rather than commitment discounts, so the ranking reflects straight commercial list pricing. Without high availability, the totals stay closer together because there is less replicated capacity, but existing enterprise commitments or hybrid-use discounts could still change the real procurement outcome.
