Storage Networking Cheatsheet¶
Azure Storage provides several options for securing data access through network isolation.
Note
Private Endpoints require DNS planning to avoid resolution paths that still target public endpoints.
Networking Option Comparison¶
| Option | DNS Behavior | Security | Cost | Setup Complexity |
|---|---|---|---|---|
| Public Access | Public IP | Low | Free | Minimal |
| Service Endpoint | Public IP (Virtual) | Medium | Free | Simple |
| Private Endpoint | Private VNet IP | High | Paid (Hourly + Data) | Moderate |
| Trusted Services | Internal Backbone | High | Free | Automatic |
