Azure Private Link consulting and hands-on support

Azure Private Link is an Azure networking feature that enables private connectivity from a virtual network to supported Azure PaaS services through private endpoints, keeping traffic on the Microsoft backbone rather than the public internet. It is commonly used by platform, security, and DevOps teams to reduce exposure of services like Storage, Key Vault, and managed databases while maintaining predictable access controls.

Implementations typically pair private endpoints with private DNS zones for consistent name resolution across hub-and-spoke VNets and connected on-premises networks, and are often combined with policies that restrict or disable public network access. For platform details, see the Azure Private Link documentation.

• Creates private endpoints with private IPs for supported Azure and partner services
• Supports access from peered VNets and hybrid networks without public ingress
• Integrates with Azure Private DNS to map service FQDNs to private endpoints
• Enables approval workflows and cross-subscription patterns for shared platforms
• Helps standardize subnet, DNS, and governance controls for consistent operations

Azure Private Link enables private connectivity from a virtual network to Azure PaaS services via private endpoints, keeping service access on the Microsoft backbone instead of the public internet. It is used to reduce exposure, improve network isolation, and enforce tighter access controls for sensitive workloads.

• Removes public ingress dependency by mapping service access to private IPs in a VNet, reducing attack surface.
• Reduces data exfiltration paths by keeping traffic off the public internet and limiting access to approved networks.
• Supports strong network segmentation by placing private endpoints in dedicated subnets and controlling routing with UDRs and NSGs.
• Improves governance by enabling consistent patterns for private endpoint creation, approval workflows, and policy enforcement across subscriptions.
• Enables private access to many Azure PaaS services such as Storage, Key Vault, SQL Database, Container Registry, and others that support Private Link.
• Simplifies service hardening by pairing private endpoints with “public network access disabled” on supported services.
• Provides predictable DNS resolution with Private DNS zones and custom DNS forwarding, avoiding public DNS records for private services.
• Works with hub-and-spoke and shared services architectures, including access from on-premises via VPN/ExpressRoute into the VNet.
• Helps meet compliance requirements by constraining data paths and demonstrating private connectivity controls for regulated environments.
• Improves operational clarity by making service dependencies explicit through endpoint resources, DNS zones, and approved connections.

Key trade-offs include added DNS and subnet design complexity, private endpoint IP consumption, and the need to plan for cross-tenant or cross-subscription approval flows. For internet-facing applications, Private Link is typically combined with separate ingress components while keeping backend PaaS dependencies private.

Our experience with Azure Private Link helped us develop repeatable delivery patterns, infrastructure-as-code modules, and operational runbooks for moving Azure PaaS access onto private endpoints—improving network isolation, reducing public exposure, and making DNS and ownership boundaries clearer for platform teams.

Some of the things we did include:

• Performed Private Link readiness assessments across subscriptions and landing zones, inventorying PaaS dependencies, identifying public network access risks, and producing phased cutover plans with rollback steps.
• Implemented private endpoints for common services (Storage, Key Vault, Azure SQL, Container Registry, Service Bus) and validated end-to-end connectivity with public network access disabled where appropriate.
• Designed Private Link DNS architectures using private DNS zones and split-horizon patterns, including on-prem integration over VPN/ExpressRoute with documented conditional forwarders and troubleshooting steps.
• Standardized deployments using Terraform, including modules for private endpoints, DNS zone links, RBAC assignments, naming/tagging conventions, and subnet sizing guardrails.
• Hardened platform workloads on Azure Kubernetes Service (AKS) by routing image pulls, secrets retrieval, and service-to-service calls through Private Link and validating node/pod egress behavior.
• Implemented governance controls with Azure Policy to restrict public endpoints on PaaS resources, enforce Private Link usage for regulated workloads, and report on drift and approved exceptions.
• Planned and executed migrations from public endpoints to Private Link with coordinated application configuration changes, DNS updates, and change management to minimize downtime.
• Built monitoring and troubleshooting playbooks for DNS resolution failures, private endpoint connection states, NIC/IP lifecycle management, and alerting into existing observability workflows.
• Validated performance and operational limits for higher-throughput workloads, including connection scaling considerations, latency checks, and guidance on endpoint placement, subnet capacity, and multi-region patterns.
• Established day-2 operating procedures for request/approval flows, endpoint ownership, exception handling, and cost/chargeback tagging so Private Link remained manageable at enterprise scale.

This delivery work helped us accumulate significant knowledge across Azure Private Link use-cases—from network and DNS design through governance, migration execution, and day-2 operations—and enables us to deliver high-quality Azure Private Link setups that reduce exposure and simplify secure access for client platforms.

Some of the things we can help you do with Azure Private Link include:

• Run a Private Link readiness assessment of your Azure PaaS exposure, network topology, and DNS to produce a prioritized findings report with remediation steps.
• Define an adoption roadmap for rolling out private endpoints across subscriptions, environments, and landing zones with clear ownership, sequencing, and standards.
• Design and implement private endpoints for services such as Storage, Key Vault, and Azure SQL with subnet planning, routing considerations, and least-privilege access.
• Implement Private DNS Zones and hybrid DNS forwarding patterns to ensure reliable name resolution across hub/spoke VNets, on-prem, and shared services networks.
• Codify Private Link and DNS deployments with IaC (Terraform/Bicep) and integrate into CI/CD for repeatable, reviewable releases and faster environment provisioning.
• Establish security guardrails and governance using Azure Policy, RBAC, tagging, and approval workflows to reduce data exfiltration risk and enforce standards at scale.
• Harden network controls around private endpoints (NSGs, UDRs, firewall integration) to meet segmentation goals and compliance requirements.
• Optimize cost and operational overhead by standardizing endpoint/DNS patterns, minimizing duplicate zones, and preventing misconfigurations that drive troubleshooting time.
• Set up observability and operational runbooks for endpoint health, DNS failures, and connectivity troubleshooting with actionable alerts and escalation paths.
• Enable platform and application teams with hands-on workshops and documentation so they can adopt Private Link safely in day-to-day delivery.
