Resource Group: wusm-prod-rg-adb

Overview

The resource group wusm-prod-rg-adb is designed to host various Azure resources primarily for application workloads running on Azure Databricks. This resource group serves as a centralized location for managing services such as virtual machines, network interfaces, managed identities, and Azure storage accounts, integrating them to facilitate processing and analysis of large datasets.

Resources

1. User Assigned Identities

• Type: Microsoft.ManagedIdentity/userAssignedIdentities
• Name: dbmanagedidentity, dbmanagedidentitydb3xby7iyqlds
• Purpose: User-assigned managed identities provide services within Azure resources to authenticate to Azure services without indicating credentials. These managed identities are linked to various Databricks clusters and improve security by avoiding credential management.

2. Network Interfaces

• Network interfaces are critical for allowing Azure VMs to communicate with each other and the outside world. The following interfaces are configured:

3. Virtual Machines

Multiple virtual machines are deployed using the Databricks image:

• VMs configured:
  • 049d4857a5be440983b989979824f9be
  • 0fce93c436a9481a9e9a86184d59af80
  • 4290cc7f6294412e8673beb8dfa4988f
  • 5e6e42c7d4244536aed87156d597a3c5
  • 7e23be6b9d934facbfaa0765117c9697
  • 833a3e3f08744f20bbef85e568ab468b
  • 9b1bdd523b9646c88904b627eafa749d
  • a484a31417c34a1bb45be9c16f636d36
  • d6f452bad7ac4401a5aa3aa569ebcd1a
  • e415a2a4f6c94e698a60f0ceed9bbeb0

Each VM connects to a public NIC for external communications and a private NIC for internal communications.

4. Storage Accounts

• Type: Microsoft.Storage/storageAccounts
• Name: wusmprodadbstorage
• Access Tier: Hot
• Purpose: The storage account is configured to host Azure Blob storage, enabling data collection and scalable storage for data-driven insights. The encryption and networking policies are set to enhance data security.
• Configuration: Standard_GRS availability and configured to deny public access, ensuring data security.

Data Storage

The wusmprodadbstorage account is the primary storage utilized in this resource group. It helps in managing large datasets through Blob storage, file storage, and table storage services. Each virtual machine may also leverage the storage account as persistent disk storage, allowing VMs to retain data across restarts.

Networking

This resource group employs a significant networking setup:

• Virtual Network:
  • Name: wusm-prod-vnet-main
  • Subnets:
    • ADBContainerSubnet: where private NICs connect for secure internal communications.
    • ADBHostSubnet: where public NICs attach to allow external access.

Networking features:

• All interface configurations define IP allocation as Dynamic with accelerated networking enabled, enhancing throughput and latency performance.

Security Overview

Security Recommendations:

1. User-Assigned Managed Identities:

   • The use of managed identities is a strong security practice, allowing services to authenticate without embedded secrets.

2. Network Security:

   • Set up Network Security Groups (NSGs) to ensure only approved traffic can reach these network interfaces.

3. Storage Account Security:

   • Ensure to regularly assess access controls and monitor any incoming/outgoing traffic associated with the storage account. Public access is denied; however, configuring IP rules to restrict access to only specific resources can add an extra layer of security.

4. VM Security:

   • Deploy security patches automatically and monitor all VMs through Azure Monitor for any unauthorized access attempts.

Other Information

• Cost Management: Utilizing "Spot" instances for virtual machines implies cost savings at the risk of potential eviction; this should be monitored regularly.
• Scalability: The architecture allows for auto-scaling, particularly for Databricks workloads, where additional resources can be deployed based on demand.
• Backup Strategies: Establish regular backups for the Azure Storage and disk snapshots for the VMs to permit disaster recovery.

This resource group's configuration aims to balance performance, security, and operational overhead, positioning it to meet both current and future workload requirements effectively.
