Resource Group: wusm-prod-rg-main

Overview

The wusm-prod-rg-main resource group is designed for the management of various Azure resources deployed for a production environment focused on cognitive services, Databricks workloads, and data management. This resource group integrates multiple services such as Azure Cognitive Services, Databricks workspaces, Azure Key Vaults, Log Analytics, and various Azure Storage accounts, which collectively support data processing, analytics, and machine learning operations centered around healthcare and biostatistics.

Resources

1. Cognitive Services Accounts

   • Type: Microsoft.CognitiveServices/accounts
   • Name: Various (e.g., accounts_open_ai_moving_stories_translator_name)
   • Properties:
     • Location: Generally centralized in regions like centralus, eastus, and northcentralus.
     • Network ACLs: Set to deny public access by default; specific IPs (e.g., 128.252.0.0/16) are allowed.
     • Relationship: These accounts use the network subnets (e.g., ADBContainerSubnet, ADBHostSubnet) for secure internal communication.

2. Databricks Workspaces

   • Type: Microsoft.Databricks/workspaces
   • Name: (e.g., workspaces_wusm_prod_adb_name)
   • Properties:
     • Allocated within specific subnets, ensuring Databricks clusters can communicate securely and efficiently.
     • Network Security Groups (NSGs) control traffic flow to/from Databricks components.

3. Key Vaults

   • Type: Microsoft.KeyVault/vaults
   • Name: Various (e.g., vaults_wusm_prod_kv_name)
   • Properties:
     • Provides secure storage for secrets, certificates, and keys.
     • Network ACLs determine who can access the secrets. E.g., access is denied by default with specific IP ranges permitted.
     • Secrets include important configuration details such as database connection strings and API keys.

4. Public IP Addresses

   • Type: Microsoft.Network/publicIPAddresses
   • Name: For Application Gateway (e.g., publicIPAddresses_wusm_prod_appgw_name)
   • Properties:
     • Static allocation for robust networking configurations.
     • Supports DDoS protection with assigned public IP.

5. Storage Accounts

   • Type: Microsoft.Storage/storageAccounts
   • Names: Various (e.g., storageAccounts_wusmprodadls_name, storageAccounts_wusmfiledrop_name)
   • Properties:
     • Storage type includes Blob and File storage options.
     • Access Control Lists (ACLs) restrict access to specific subnets, enhancing security.
     • Encryption is enabled, and HTTPS is enforced for secure access.

6. Network Security Groups (NSGs)

   • Type: Microsoft.Network/networkSecurityGroups
   • Names: Various NSGs control access based on network rules critical for services like Databricks and Application Gateway.

7. Network Interfaces

   • Type: Microsoft.Network/networkInterfaces
   • Names: Commonly tied to VMs and Databricks clusters.

8. Private Endpoints

   • Type: Microsoft.Network/privateEndpoints
   • Names: Multiple for Azure Storage, Cognitive Services, and Databricks.
   • Properties:
     • Enhance secure connectivity without exposing the public IP.

Data Storage

Data is primarily stored across various Azure Storage Accounts and integrated with Azure Key Vault for secure management of secrets:

• Storage Accounts:
  • Provide different storage capabilities like Blob storage for unstructured data and File Shares for file storage. E.g., storageAccounts_wusmprodadls_name for data lakes, each having ACLs limiting access to designated networks.
• Databricks Integration:
  • Databricks can utilize different storage accounts directly, enabling scalable processing jobs across stored datasets.

Networking

The resource group employs a well-defined network structure:

• Virtual Network:
  • The primary virtual network (virtualNetworks_wusm_prod_vnet_main_name) has multiple subnets configured for specific services.
• Subnets:
  • Subnets like ADBContainerSubnet, ADBHostSubnet, AuxSubnet, and AppGWSubnet are designed to segment the network components based on roles and security requirements.
  • Each subnet features routing rules and NSG configurations to monitor and control incoming and outgoing traffic.
• Private Endpoints:
  • Used extensively with services to allow secure access to resources across the network, reducing public exposure.
• IP Allocations:
  • Dynamic IP assignments for VMs and static IPs for critical components like Application Gateways enhance reliability and communication efficiency.

Security Overview

Security measures within this resource group include:

• Network Security Controls:
  • The default action for network ACLs is set to deny, with specific IP ranges allowed. The configurations for Sublocal Users and service restrictions restrict accesses.
• Private Link Services:
  • Essential for secure access to Azure services while blocking public internet routes to sensitive applications.
• Key Vault Access Policies:
  • Strongly configured for role-based access control, ensuring only designated identities can access sensitive information.
• Recommendations:
  • Regularly monitor and audit ACL configurations for compliance.
  • Strengthen user access policies in Key Vaults and restrict NSGs to minimum necessary access.

Other Information

• Cost Management:
  • Services are tagged (e.g., Cost Center) to facilitate tracking expenses accurately across different departments and initiatives.
• Scalability:
  • Resources such as Azure Databricks can be scaled up/down based on the requirement for computing power while utilizing services in conjunction with Azure Storage for large datasets.
• Logging and Monitoring:
  • Log Analytics workspaces are integrated to provide insights into usage metrics and application insights.

This comprehensive breakdown of your Azure Resource Group ensures structured management, security, cost control, and optimal performance of your cloud architecture.
