Azure Cost Optimize
This workflow analyzes Infrastructure-as-Code (IaC) files and Azure resources to generate cost optimization recommendations. It creates individual GitHub issues for each optimization opportunity plus one EPIC issue to coordinate implementation, enabling efficient tracking and execution of cost savings initiatives.
Prerequisites
- Azure MCP server configured and authenticated
- GitHub MCP server configured and authenticated
- Target GitHub repository identified
- Azure resources deployed (IaC files optional but helpful)
- Prefer Azure MCP tools (
azmcp-*) over direct Azure CLI when available
Workflow Steps
Step 1: Get Azure Best Practices
Action: Retrieve cost optimization best practices before analysis Tools: Azure MCP best practices tool Process:
- Load Best Practices:
- Execute
azmcp-bestpractices-getto get some of the latest Azure optimization guidelines. This may not cover all scenarios but provides a foundation. - Use these practices to inform subsequent analysis and recommendations as much as possible
- Reference best practices in optimization recommendations, either from the MCP tool output or general Azure documentation
- Execute
Step 2: Discover Azure Infrastructure
Action: Dynamically discover and analyze Azure resources and configurations Tools: Azure MCP tools + Azure CLI fallback + Local file system access Process:
Resource Discovery:
- Execute
azmcp-subscription-listto find available subscriptions - Execute
azmcp-group-list --subscription <subscription-id>to find resource groups - Get a list of all resources in the relevant group(s):
- Use
az resource list --subscription <id> --resource-group <name>
- Use
- For each resource type, use MCP tools first if possible, then CLI fallback:
azmcp-cosmos-account-list --subscription <id>- Cosmos DB accountsazmcp-storage-account-list --subscription <id>- Storage accountsazmcp-monitor-workspace-list --subscription <id>- Log Analytics workspacesazmcp-keyvault-key-list- Key Vaultsaz webapp list- Web Apps (fallback - no MCP tool available)az appservice plan list- App Service Plans (fallback)az functionapp list- Function Apps (fallback)az sql server list- SQL Servers (fallback)az redis list- Redis Cache (fallback)- ... and so on for other resource types
- Execute
IaC Detection:
- Use
file_searchto scan for IaC files: "/*.bicep", "/*.tf", "/main.json", "/template.json" - Parse resource definitions to understand intended configurations
- Compare against discovered resources to identify discrepancies
- Note presence of IaC files for implementation recommendations later on
- Do NOT use any other file from the repository, only IaC files. Using other files is NOT allowed as it is not a source of truth.
- If you do not find IaC files, then STOP and report no IaC files found to the user.
- Use
Configuration Analysis:
- Extract current SKUs, tiers, and settings for each resource
- Identify resource relationships and dependencies
- Map resource utilization patterns where available
Step 3: Collect Usage Metrics & Validate Current Costs
Action: Gather utilization data AND verify actual resource costs Tools: Azure MCP monitoring tools + Azure CLI Process:
Find Monitoring Sources:
- Use
azmcp-monitor-workspace-list --subscription <id>to find Log Analytics workspaces - Use
azmcp-monitor-table-list --subscription <id> --workspace <name> --table-type "CustomLog"to discover available data
- Use
Execute Usage Queries:
- Use
azmcp-monitor-log-querywith these predefined queries:- Query: "recent" for recent activity patterns
- Query: "errors" for error-level logs indicating issues
- For custom analysis, use KQL queries:
// CPU utilization for App Services AppServiceAppLogs | where TimeGenerated > ago(7d) | summarize avg(CpuTime) by Resource, bin(TimeGenerated, 1h) // Cosmos DB RU consumption AzureDiagnostics | where ResourceProvider == "MICROSOFT.DOCUMENTDB" | where TimeGenerated > ago(7d) | summarize avg(RequestCharge) by Resource // Storage account access patterns StorageBlobLogs | where TimeGenerated > ago(7d) | summarize RequestCount=count() by AccountName, bin(TimeGenerated, 1d)- Use
Calculate Baseline Metrics:
- CPU/Memory utilization averages
- Database throughput patterns
- Storage access frequency
- Function execution rates
VALIDATE CURRENT COSTS:
- Using the SKU/tier configurations discovered in Step 2
- Look up current Azure pricing at https://azure.microsoft.com/pricing/ or use
az billingcommands - Document: Resource → Current SKU → Estimated monthly cost
- Calculate realistic current monthly total before proceeding to recommendations
Step 4: Generate Cost Optimization Recommendations
Action: Analyze resources to identify optimization opportunities Tools: Local analysis using collected data Process:
Apply Optimization Patterns based on resource types found:
Compute Optimizations:
- App Service Plans: Right-size based on CPU/memory usage
- Function Apps: Premium → Consumption plan for low usage
- Virtual Machines: Scale down oversized instances
Database Optimizations:
- Cosmos DB:
- Provisioned → Serverless for variable workloads
- Right-size RU/s based on actual usage
- SQL Database: Right-size service tiers based on DTU usage
Storage Optimizations:
- Implement lifecycle policies (Hot → Cool → Archive)
- Consolidate redundant storage accounts
- Right-size storage tiers based on access patterns
Infrastructure Optimizations:
- Remove unused/redundant resources
- Implement auto-scaling where beneficial
- Schedule non-production environments
Calculate Evidence-Based Savings:
- Current validated cost → Target cost = Savings
- Document pricing source for both current and target configurations
Calculate Priority Score for each recommendation:
Priority Score = (Value Score × Monthly Savings) / (Risk Score × Implementation Days) High Priority: Score > 20 Medium Priority: Score 5-20 Low Priority: Score < 5Validate Recommendations:
- Ensure Azure CLI commands are accurate
- Verify estimated savings calculations
- Assess implementation risks and prerequisites
- Ensure all savings calculations have supporting evidence
Step 5: User Confirmation
Action: Present summary and get approval before creating GitHub issues Process:
Display Optimization Summary:
🎯 Azure Cost Optimization Summary 📊 Analysis Results: • Total Resources Analyzed: X • Current Monthly Cost: $X • Potential Monthly Savings: $Y • Optimization Opportunities: Z • High Priority Items: N 🏆 Recommendations: 1. [Resource]: [Current SKU] → [Target SKU] = $X/month savings - [Risk Level] | [Implementation Effort] 2. [Resource]: [Current Config] → [Target Config] = $Y/month savings - [Risk Level] | [Implementation Effort] 3. [Resource]: [Current Config] → [Target Config] = $Z/month savings - [Risk Level] | [Implementation Effort] ... and so on 💡 This will create: • Y individual GitHub issues (one per optimization) • 1 EPIC issue to coordinate implementation ❓ Proceed with creating GitHub issues? (y/n)Wait for User Confirmation: Only proceed if user confirms
Step 6: Create Individual Optimization Issues
Action: Create separate GitHub issues for each optimization opportunity. Label them with "cost-optimization" (green color), "azure" (blue color).
MCP Tools Required: create_issue for each recommendation
Process:
Create Individual Issues using this template:
Title Format:
[COST-OPT] [Resource Type] - [Brief Description] - $X/month savingsBody Template:
## 💰 Cost Optimization: [Brief Title] **Monthly Savings**: $X | **Risk Level**: [Low/Medium/High] | **Implementation Effort**: X days ### 📋 Description [Clear explanation of the optimization and why it's needed] ### 🔧 Implementation **IaC Files Detected**: [Yes/No - based on file_search results] ```bash # If IaC files found: Show IaC modifications + deployment # File: infrastructure/bicep/modules/app-service.bicep # Change: sku.name: 'S3' → 'B2' az deployment group create --resource-group [rg] --template-file infrastructure/bicep/main.bicep # If no IaC files: Direct Azure CLI commands + warning # ⚠️ No IaC files found. If they exist elsewhere, modify those instead. az appservice plan update --name [plan] --sku B2📊 Evidence
- Current Configuration: [details]

⚠️ Risks & Considerations
- [Risk 1 and mitigation]
- [Risk 2 and mitigation]
Priority Score: X | Value: X/10 | Risk: X/10 ```
Step 7: Create EPIC Coordinating Issue
Action: Create master issue to track all optimization work. Label it with "cost-optimization" (green color), "azure" (blue color), and "epic" (purple color).
MCP Tools Required: create_issue for EPIC
Note about mermaid diagrams: Ensure you verify mermaid syntax is correct and create the diagrams taking accessibility guidelines into account (styling, colors, etc.).
Process:
Create EPIC Issue:
Title:
[EPIC] Azure Cost Optimization Initiative - $X/month potential savingsBody Template:
# 🎯 Azure Cost Optimization EPIC **Total Potential Savings**: $X/month | **Implementation Timeline**: X weeks ## 📊 Executive Summary - **Resources Analyzed**: X - **Optimization Opportunities**: Y - **Total Monthly Savings Potential**: $X - **High Priority Items**: N ## 🏗️ Current Architecture Overview ```mermaid graph TB subgraph "Resource Group: [name]" [Generated architecture diagram showing current resources and costs] end📋 Implementation Tracking
