Why the totals differ
Google Cloud is significantly cheaper for this Keycloak Extra Small configuration, costing effectively nothing compared to AWS at $156 and Azure at $164 monthly. This drastic difference is primarily due to Google Cloud's free tier for e2-micro instances, which covers the compute needs for this low-demand workload. For higher demand tiers, the pricing mechanics of sustained use discounts or committed use discounts on Google Cloud, or reserved instances on AWS and Azure, would become more relevant for cost optimization.
