Managing Azure Subscriptions, Resources, and Governance

1. Understanding Azure Subscriptions

In Azure, a **subscription** is a logical unit that provides access to Azure services and resources. It acts as a boundary for **billing, identity, and resource management**.

Types of Azure Subscriptions

Pay-As-You-Go – Charges based on resource usage.
Enterprise Agreement – Designed for large organizations.
Azure Free Tier – Provides free credits and limited services.
Microsoft CSP (Cloud Solution Provider) – Managed by partners.

Subscription Management Best Practices

Use **multiple subscriptions** to separate environments (Dev, Test, Production).
Leverage **Azure Cost Management + Billing** to track expenses.
Enable **spending limits** to prevent unexpected charges.
Apply **tags** to categorize resources based on projects, departments, or cost centers.

2. Managing Azure Resources Efficiently

Azure resources are **computing, storage, networking, and other services** that are deployed within subscriptions. Effective resource management is key to optimizing costs and performance.

Resource Organization Strategies

Use **Resource Groups** to group related resources.
Apply **naming conventions** for consistency (e.g., rg-prod-app1-eastus).
Implement **role-based access control (RBAC)** to restrict access.
Use **Azure Policy** to enforce compliance.

3. Azure Governance and Compliance

Governance in Azure ensures compliance, security, and cost control across subscriptions and resources.

Azure Governance Tools

Tool	Purpose
Azure Policy	Enforce rules for compliance and resource management.
Azure Blueprints	Automate environment setup with predefined templates.
Role-Based Access Control (RBAC)	Control access based on user roles.
Azure Cost Management	Monitor and optimize cloud spending.
Azure Monitor	Track and analyze system performance.

4. Best Practices for Azure Subscription and Governance

💰 Cost Optimization

Use **Reserved Instances** for predictable workloads.
Enable **Auto-shutdown for VMs** to save costs.
Use **Azure Advisor** to get cost-saving recommendations.
Implement **spending alerts** to track and control costs.

🔐 Security and Compliance

Enable **Azure Security Center** for continuous monitoring.
Implement **Multi-Factor Authentication (MFA)** for all admin accounts.
Use **private endpoints** to enhance data security.
Regularly audit **activity logs** using Azure Monitor.

📊 Performance Management

Use **Azure Monitor and Log Analytics** for real-time insights.
Set up **scaling rules** for applications to handle peak loads.
Optimize storage with **Azure Storage Tiers** (Hot, Cool, Archive).
Use **Azure Traffic Manager** for global load balancing.

5. Conclusion

Managing Azure subscriptions and resources efficiently requires strategic planning, cost management, and governance policies. By following best practices and leveraging Azure governance tools, organizations can ensure **security, compliance, and cost-effectiveness**.
