Why this sizing

Confluence Data Center at the medium tier maps to the medium reference architecture on Google Cloud in us-central1. Compute is the largest line item in this estimate, accounting for 100% of monthly cost. High availability is not included here, so this baseline stays lean and leaves failover headroom out of the monthly total. This tier is primarily a compute sizing exercise rather than a storage-heavy one.

Not included in this estimate

Vendor licensing and support
Professional services
Network egress
Compliance controls
Backup storage
Monitoring

Estimate excludes shared-home EFS/NFS storage, collaborative editing proxy details, Marketplace app overhead, and managed database HA costs not captured in the benchmark summary.

The HA toggle models load balancer overhead only; clustered Confluence application and Synchrony nodes are already represented in the base deployment.
