We are frequently asked to share the best practice for Power platform to connect backend service or database and storage and so on. I summarize it for future reference.

Power Platform + Azure Integration Validation Checklist

๐Ÿ”ง 1. Virtual Network Configuration

  • [ ] Ensure non-overlapping CIDR blocks across all VNets (e.g., avoid using 10.0.0.0/16 in both).
  • [ ] Confirm VNet peering is established if cross-VNet communication is required.
  • [ ] Validate DNS resolution across VNets (especially if using Private DNS Zones).

๐Ÿ” 2. Private Endpoint Setup

  • [ ] Confirm private endpoints are created for each Azure resource (SQL, Storage).
  • [ ] If using multiple VNets, verify:
    • [ ] Each VNet has its own private endpoint or
    • [ ] A shared private endpoint is accessible via peering and DNS zone linking.
  • [ ] Ensure Private DNS Zones are linked to all VNets that need to resolve the endpoint.

๐Ÿ“ก 3. Route Table Configuration

  • [ ] Route tables include specific routes to private endpoint IPs.
  • [ ] Avoid default routes (0.0.0.0/0) that send traffic to the internet unless explicitly required.
  • [ ] Use service tags like AzureSQL, Storage, and PowerPlatform where applicable.
  • [ ] Confirm no conflicting UDRs (User Defined Routes) that override private endpoint routing.

๐Ÿ›ก๏ธ 4. Network Security Groups (NSGs)

  • [ ] NSGs allow traffic to/from Power Platform IP ranges or service tags.
  • [ ] NSGs do not block traffic to private endpoint IPs.

๐Ÿงญ 5. Power Platform Environment Settings

  • [ ] Environment is configured with VNet injection (if applicable).
  • [ ] Subnet delegated to Microsoft.PowerPlatform.
  • [ ] CIDR block is at least /25 for production workloads.

๐Ÿงช 6. Connectivity Testing

  • [ ] Test connection to SQL Server and Storage Account from Power Apps.
  • [ ] Validate DNS resolution from Power Platform to private endpoint FQDNs.
  • [ ] Use tools like nslookup, Test-NetConnection, or Azure Network Watcher for diagnostics.
