This is a very powerful mechanism for Microsoft partners to reach Azure customers. This needs to be overridden to connect using your private endpoint. The following diagram summarizes the Azure Private Link architecture with respect to the customer VNet and the Snowflake VNet. Meaning, you can control the egress to the PaaS resource. If you try to connect to a private link resource without Aure RBAC, use the manual method to allow the owner of the resource to approve the connection. And here is also a description for the global peering of VNet: The ability to transfer data between virtual networks across Azure subscriptions, Azure Active Directory tenants, deployment models, and Azure regions. The interface is assigned dynamically private IP addresses from the subnet that maps to the private link resource. The service could be an Azure service such as Azure Storage, Azure Cosmos DB, SQL, etc. Private Link introduces a private IP for a given instance of the PaaS Service and the service is accessed via the private IP. Service providers can render their services in their own virtual network and consumers can access those services in their local virtual network. Where the dot is actually the private endpoint, which will have a private ip belonging to the range of the subnet (within the VNET) it belongs too. The private link resource can be deployed in a different region than the virtual network and private endpoint. Connections can only be establish in a single direction. The following is a list of available private link resource types: When using private endpoints for Azure services, traffic is secured to a specific private link resource. (Source: AWS) ( Log Out /  Private Link/Endpoint is a huge step in Azure Networking as it allows to make private any internet facing public service (Like PaaS services: Azure SQL, Azure Storage…), and provides a unified way to expose and consume services between tenants, partners or … Private Link allows you to create private endpoints across tenants, and to create endpoints for Azure Load Balancers. The pricing for Private Link is based on two elements: A cost per Private Endpoint of $0.01 per hour ($ 7.3 per month) and A cost per GB of bandwidth (in/out) over Private Link ($0.01 per GB) When Service Endpoints are enabled, the PaaS resource sees traffic coming from your VNet private IP, not the public IP. Alias is a unique moniker that is generated when the service owner creates the private link service behind a standard load balancer. Ultimately, if you are considering either solution, Private Link versus Service Endpoint, then you are probably concerned with security and with that said, Private Link is superior to Service Endpoints. ( Log Out /  NSG Flow logs and monitoring information for outbound connections are still supported and can be used. This video goes over two ways of restricting access to Microsoft Azures PaaS services; Service Endpoints and Private Endpoints. Service Endpoints work by enabling your VNet or subnet(s) to support the Service Endpoint, and once enabled, you can configure which PaaS resource(s) can accept traffic from those subnet(s)/VNets. A private link resource is the destination target of a given private endpoint. For details, see Azure limits.
