At the Apsara Conference 2020, Zhu Shunmin, Researcher of Alibaba Cloud’s intelligent network products, introduced the PrivateLink, a product for private network connection. PrivateLink uses Alibaba Cloud’s private network for business interaction. With private network connections, users of Alibaba Cloud can access services provided by other Virtual Private Clouds (VPCs) through private networks, without additional Internet egress services. This ensures higher security and better network quality by preventing interactive data from going through the Internet.

What is PrivateLink?

What Scenarios May Require PrivateLink?

Scenario Example 1: Sharing Cloud Services Across VPC Networks

As shown above, to achieve private access to the SLB service in VPC2, the SLB service needs to be added into the endpoint service as a service resource first. Then, endpoints for accessing the SLB service need to be created in VPC1. Thus, VPC1 can access the SLB service in VPC2 through endpoints.

Scenario Practice 1: An enterprise-level SaaS cloud service allows services to be provided on Alibaba Cloud’s intranet. Enterprises or individuals can access service resources across regions and share the low-latency, high-availability, and high-security network of Alibaba Cloud.

Scenario Practice 2: Large and medium-sized enterprises or multinational companies set up the service releasing layer at the enterprise level. Each subsidiary and overseas office can access service resources through PrivateLink, achieving multi-account, multi-VPC fast interconnection, and security. PrivateLink can help these enterprises and companies migrate all their business to the cloud, making business usage and interconnection more convenient and reliable.

Scenario Example 2: Sharing On-Cloud Services in One VPC With a Local Data Center

As shown above, to achieve private access in a local data center with the SLB service in VPC2, the SLB service needs to be shared with VPC1 first. Then, VPC1 will be connected with a local data center through a leased line, VPN gateway, or Smart Access Gateway (SAG.) In this way, private access from a local data center with on-cloud SLB services can be achieved.

Scenario Practice: When Independent Software Vendors (ISV) and System Integrators (SI) construct cloud ecosystems with enterprises, more of their offline services are migrated to the cloud. They build their own services on Alibaba Cloud or connect their local Internet Data Center (IDC) services to Alibaba Cloud. By doing so, they can help their long-term enterprise users to achieve more efficient and high-quality cloud migration.
