Azure Private Link is an Azure networking capability that provides private access to supported PaaS services through private endpoints in a virtual network, keeping service traffic off the public internet. It is commonly used by platform, security, and DevOps teams to reduce data exfiltration risk and enforce stronger network isolation for services such as Storage, Key Vault, and managed databases.
It is typically implemented as part of a broader VNet and subnet design, with private DNS zones for consistent name resolution and governance controls to limit or disable public network access. For platform details, see the Azure Private Link documentation.
Networking, in the context of computer science and information technology, refers to the practice of connecting computers, servers, mainframes, network devices, peripherals, or other devices to exchange data and share resources. It encompasses both the physical (hardware) and logical (software) aspects of connections between devices. The primary goal of networking is to enable the sharing of data and resources, thereby improving efficiency and accessibility within and across computing environments. Networks can vary in size, ranging from simple local area networks (LANs) connecting a few devices in a single office, to complex wide area networks (WANs) spanning multiple geographic locations around the globe. Networking technologies and protocols facilitate communication and data transfer across these connections, adhering to standardized rules to ensure reliable and secure information exchange.
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.
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.
For implementation details and service coverage, see Microsoft’s Azure Private Link overview.
Our experience with Azure Private Link helped us build repeatable delivery patterns, IaC modules, and operational runbooks for securing access to Azure PaaS services through private endpoints, with stronger network isolation, clearer ownership, and fewer public exposure paths for enterprise platforms.
Some of the things we did include:
This delivery work helped us accumulate significant knowledge across Azure Private Link use-cases—from subnet and DNS design to governance 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.
