  --time-period Start=2024-01-01,End=2024-12-31 \
  --granularity MONTHLY \
  --metrics BlendedCost \
  --prediction

Azure Cost Queries

az consumption usage list \
  --start-date 2024-01-01 \
  --end-date 2024-01-31

# Get cost by resource group
az consumption usage list \
  --start-date 2024-01-01 \
  --end-date 2024-01-31 | jq 'group_by(.properties.resourceGroup)'

# Get budget status
az costmanagement budget list --scope "/subscriptions/{subscription-id}"

GCP Cost Queries

bash

# Get project costs
bq query \
  --project_id=<billing-project-id> \
  "SELECT
     project.id as project_id,
     invoice.month as month,
     SUM(cost) as total_cost
   FROM `<billing-export-dataset>`
   WHERE invoice.month = '202401'
   GROUP BY project_id, month"

# Get costs by label
bq query \
  --project_id=<billing-project-id> \
  "SELECT
     labels.value as environment,
     SUM(cost) as total_cost
   FROM `<billing-export-dataset>`
   WHERE labels.key = 'environment'
   GROUP BY labels.value"

Common Cost Issues and Solutions

Issue	Root Cause	Solution
Unexpected high costs	Unoptimized instances	Right-size, use Savings Plans
Data transfer costs	Cross-region transfers	Use regional resources, CDN
Storage costs growing	Old data retention	Lifecycle policies, deletion
Idle resources	Forgotten resources	Automate cleanup, monitoring
Development costs high	Production configs in dev	Separate environments, tags

Cost Management Best Practices

Monitor regularly - Review costs weekly or monthly
Set budgets - Create budgets for all projects
Use alerts - Notify team of cost anomalies
Tag everything - Enable cost allocation
Review recommendations - Act on provider suggestions
Use savings plans - Commit to predictable workloads
Right-size resources - Match resources to needs
Clean up unused - Remove idle resources regularly
Automate cost optimization - Use scripts and tools
Educate team - Train on cost awareness
