GCP Cloud Bigtable — commitment brief

Data sourced: March 2026. Verify current figures at the Google Cloud Pricing Calculator.

Coverage summary

Cloud Bigtable supports spend-based committed use discounts (CUDs) that apply to Bigtable node compute capacity across all regions and projects within a billing account. A 1-yr commitment delivers a 20% discount and a 3-yr commitment delivers a 40% discount over on-demand pricing. The CUD applies flexibly to all eligible Bigtable node usage regardless of the specific instance or cluster location, making it well-suited for organizations with Bigtable footprints spread across multiple regions.

What is covered: Bigtable node compute capacity measured in nodes — both SSD and HDD node types — across all instances and clusters in any region within the billing account.

What is not covered: Bigtable storage costs (SSD and HDD capacity beyond what nodes provide), backup storage, and network data transfer charges.

CUD types

Cloud Bigtable offers spend-based CUDs only. You commit to a minimum hourly dollar spend on Bigtable compute capacity. The commitment automatically applies across all Bigtable clusters in any region within the billing account, providing broad flexibility. Both 1-yr (20% off) and 3-yr (40% off) terms are available.

Machine type / SKU coverage

SKU	Spend CUD	1-yr discount	3-yr discount	Notes
SSD nodes	✅ Yes	~20%	~40%	Node compute capacity covered; storage is separate
HDD nodes	✅ Yes	~20%	~40%	Node compute capacity covered; storage is separate
SSD storage	❌ No	—	—	Storage costs not covered by CUD
HDD storage	❌ No	—	—	Storage costs not covered by CUD
Backup storage	❌ No	—	—	Not covered
Network data transfer	❌ No	—	—	Not covered

Regional availability

Available in all commercial GCP regions. Cloud Bigtable spend-based CUDs apply across all eligible Bigtable node usage regardless of instance or cluster location within the billing account — no per-region purchase is required, making CUD coverage fully portable as your Bigtable footprint grows or shifts across regions.

⚠️ CUD availability varies by machine type and region. Always verify at GCP regions and zones before purchasing.

Archera

Google Cloud Bigtable is within Archera's commitment management scope. Archera can automate spend-based CUD purchase for Cloud Bigtable, monitor node utilization across all clusters and regions, and wrap commitments in a GRI/GSP — eliminating downside risk on over-commitment while preserving the full 20–40% discount.
