Azure Private Link provides private connectivity from a virtual network to Azure PaaS services, simplifying the network architecture and securing the connection between endpoints in Azure by eliminating data exposure to the public internet. Private Link carries traffic privately, which reduces your exposure to threats and helps you meet compliance standards.
You can now use Azure Private Link to connect to an Azure Cache for Redis instance from your virtual network via a private endpoint which is assigned a private IP address in a subnet within the virtual network. Once a private endpoint is created, all access to your Azure Cache for Redis instances will be restricted to only connections using the private IP addresses.
