What are Committed Use Discounts (CUD)?

1-3 year commitment on compute resources for up to 57% discount. Flexible CUDs for instance families, resource-based CUDs for specific types. Automatically applied.

How do Spot VMs work?

Preemptible compute at up to 91% discount. Google can preempt VM anytime (30s notice). Ideal for batch processing, CI/CD, fault-tolerant workloads.

What is Sustained Use Discount?

Automatic discount for long-term VM usage (monthly). Up to 30% for standard VMs. No commitment required, applies automatically.

How to use Active Assist for cost optimization?

AI-powered recommendations in Cloud Console. Idle resource detection, right-sizing, unattached disk cleanup, committed use recommendations. Export to BigQuery for analysis.

How to set up cost allocation labels?

Labels on resources for cost attribution (team, environment, project). Cloud Billing export to BigQuery, dashboards in Looker Studio. Enforced labeling via organization policies.

How to optimize storage costs?

Storage class lifecycle policies (Standard→Nearline→Coldline→Archive), Object Lifecycle Management, BigQuery partition expiration, unattached disk cleanup.

What is resource right-sizing?

Optimizing machine type based on actual usage. Recommender API analyzes CPU/memory utilization and suggests smaller/larger instances. Custom machine types for precise sizing.

How to monitor and alert on costs?

Cloud Billing budgets with email/Pub/Sub alerts, Cloud Monitoring dashboards, BigQuery billing export for custom analytics, programmatic budget notifications.

How to optimize network costs?

Standard tier networking (cheaper), Cloud CDN for caching, egress within region, Private Google Access instead of internet egress, Cloud Interconnect for high-volume.

What is best practice for FinOps governance?

Cross-functional FinOps team, monthly cost reviews, showback/chargeback reports, budgets per project/team, continuous optimization culture, automated recommendations.

How to estimate cloud optimization ROI?

Compare current spend vs optimized (Billing export), calculate CUD savings, right-sizing savings, waste elimination. Typically 20-40% savings in first 6 months.

FinOps na GCP — CUDs, Sustained Use a Active Assist

Snížení nákladů na Google Cloud: Committed Use Discounts, Sustained Use, Spot VMs, BigQuery sloty a doporučení Recommenderu.

Committed Use Discounts (CUDs)

Resource-based CUDs (1/3 roky, sleva 25–55 %), Spend-based CUDs (flexibilní napříč službami), Flex CUDs pro krátkodobé závazky.

Sustained Use Discounts (SUDs)

Automatické slevy až 30 % za nepřetržité používání Compute Engine v měsíci, žádné závazky, transparentní výpočet per resource.

Spot VMs a Preemptible

Spot VMs až 91 % sleva oproti on-demand, vhodné pro batch, CI/CD, stateless workloady, Spot GKE node pools, graceful shutdown 30s.

BigQuery sloty a pricing

On-demand (5 $/TB) vs editions (Standard/Enterprise/Plus), autoscaling slots, reservations, Flex Slots pro špičky, optimalizace dotazů.

Active Assist a Recommender

Idle VM detection, rightsizing recommendations, IAM recommender (nepoužitá oprávnění), unattended projects, commitment recommendations.

Cloud Billing a Budgets

Hierarchické rozpočty (org/folder/project), threshold alerts (50/90/100 %), forecast alerts, programmatic notifications (Pub/Sub), budget actions.

Billing Export do BigQuery

Detailed usage cost data, resource-level breakdown, pricing export, custom Looker Studio dashboardy, FinOps reporting, anomaly detection.

Labels a cost allocation

Resource labels (cost center, environment, team), label-based cost reports, chargeback/showback model, mandatory labels via Org Policies.

Storage tier optimization

Standard → Nearline (30 dní) → Coldline (90 dní) → Archive (365 dní), Object Lifecycle Management, Autoclass, dual/multi-region trade-offs.

Network egress optimization

CDN cache hit ratio, Premium vs Standard Tier, VPC peering místo VPN, Private Service Connect, Cloud Interconnect pro velký traffic.

GKE cost optimization

Cluster Autoscaler, Vertical Pod Autoscaler, Spot node pools, GKE Autopilot (pay-per-pod), resource quotas, cost allocation per namespace.

Pricing Calculator a TCO

Pre-deployment estimates, scenario porovnání (1/3 roky CUDs), TCO Tool pro on-prem → GCP, ROI kalkulace, sensitivity analýza.
