5.2Choosing Between Service Endpoints and Private Endpoints

Key points

Understand the difference and selection between service endpoints (optimize PaaS access via the VNet) and private endpoints (assign a private IP), and touch on Private Link Service for offering your own service via Private Link.

There are two ways to control PaaS access: a private endpoint that assigns a private IP, and a service endpoint that optimizes the route and allows the VNet on the PaaS side.

5.2.1Difference between the two

A comparison diagram with service endpoint on the left (optimizes the route from the VNet over the Azure backbone, allows the subnet on the PaaS firewall, no private IP) and private endpoint on the right (creates a NIC with a private IP in the VNet, privatizes the PaaS, reachable from on-prem too), noting features and selection.
Service endpoint vs private endpoint
  • Service endpoint: optimize the route over the Azure backbone and allow the subnet on the PaaS firewall; no private IP is assigned.
  • Private endpoint: assigns a private IP in the VNet; reachable from on-prem too and more strictly private.
  • Selection: use a private endpoint when you need a private IP / on-prem reachability / strict isolation; a service endpoint when simply allowing a VNet is enough.
  • Private Link Service: offer your own service (behind a Standard Load Balancer) to other tenants/VNets via Private Link.
