AWS PrivateLink

AWS PrivateLink enables private communication between VPCs, AWS services, and your on-premises networks without exposing your traffic to the public Internet. AWS PrivateLink makes it simple to link services across accounts and VPCs, simplifying your network design dramatically.

Interface VPC endpoints, powered by AWS PrivateLink, link you to access AWS Partners' services and AWS Marketplace-supported solutions. AWS PrivateLink provides the same degree of security and performance to your virtual network appliances or custom traffic inspection logic by powering Gateway Load Balancer endpoints.

Now, let’s learn about AWS PrivateLink.

AWS PrivateLink

AWS PrivateLink allows you to use private IP addresses in your VPC to connect to select AWS services, services hosted by other AWS accounts (referred to as endpoint services), and supported AWS Marketplace partner services. The interface endpoints are generated utilizing elastic network interfaces and IP addresses in your VPC's subnets, right inside your VPC. As a result, VPC Security Groups may be utilized to control endpoint access.

Benefits of using AWS PrivateLink

The benefits of using AWS PrivateLink are as follows:-

Secure Traffic

With AWS PrivateLink, you can securely, and scalable connect your VPCs to AWS services. Because AWS PrivateLink traffic does not pass over the public Internet, it is less vulnerable to brute force and distributed denial-of-service assaults, among other dangers. You may utilize private IP connectivity to make your services appear as though they were hosted on your private network.

Simplify Network Management

There are no firewall rules, path definitions, or route tables required to link services across various accounts and Amazon VPCs. There's no need to set up an Internet gateway, establish a VPC peering connection, or administer VPC Classless Inter-Domain Routing in your VPC (CIDRs). It's easier to manage your global network using AWS PrivateLink since it simplifies your network design.

Accelerate Cloud Migration

AWS PrivateLink makes it easier to move traditional on-premises applications to cloud-hosted SaaS services. Because your data isn't accessible to the Internet, where it may be hacked, you can relocate and utilize additional cloud services to ensure that your traffic is safe. You don't have to pick between utilizing a service and exposing your sensitive information to the Internet anymore. On our AWS Compliance Programs page, you can access the most up-to-date rules to assist customers in staying compliant.

Share services through AWS PrivateLink.

We may create our own endpoint service, which AWS PrivateLink powers, and share it with other AWS users.

The graphic below demonstrates how you may share your AWS-hosted service with other AWS customers and how other customers connect to your service. As the service provider, you set up a Network Load Balancer as the service front end in your VPC. When you build the VPC endpoint service configuration, you pick this load balancer. 

Specific AWS principals (AWS accounts, IAM users, or IAM roles) are granted access to connect to your service. The client builds an interface VPC endpoint as a service consumer, connecting the subnets they choose from their VPC and your endpoint service. Requests from service consumers are routed to the targets hosting your service via the load balancer.


We recommend that you make your service available in all Availability Zones in the Region for low latency and fault tolerance.

DNS hostnames

When a service provider launches a VPC endpoint service, AWS produces a DNS hostname for the service that is particular to the endpoint. The following is the syntax for these names:


In the us-east-2 Region, an example of a DNS hostname for a VPC endpoint service is:


We establish Regional and zonal DNS names that a service consumer may use to interact with the endpoint service when they construct an interface VPC endpoint. The following is the format for regional names:


Zonal names have the following syntax:


A service provider can also assign a private DNS name to its endpoint service, allowing customers to continue using its current DNS name. The service consumer can allow private DNS names for the interface endpoint if the service provider has linked a private DNS name with the endpoint service. If the service provider does not allow private DNS, the service consumer may need to adjust their application to utilize the public DNS name for the VPC endpoint service.

This concludes our topic of AWS PrivateLink. Let’s move on to Frequently asked questions.

Frequently Asked Questions

What is AWS PrivateLink?

AWS PrivateLink allows you to connect to some AWS services, services hosted by other AWS accounts (known as endpoint services), and supported AWS Marketplace partner services using private IP addresses in your VPC.

What is the console?

The console is a browser-based interface for accessing and interacting with GuardDuty.

What are the benefits of AWS Privatelink?

The following are the benefits of AWS Privatelink: It secures your traffic, simplifies network management, and it accelerates your cloud migration.

What is AWS SDKs?

AWS offers software development kits (SDKs), which include libraries and sample code for various programming languages and platforms.

What is Amazon GuardDuty?

It is a continuous security monitoring service that analyses and processes the data sources: AWS CloudTrail management event logs, VPC Flow, LogsCloudTrail S3 data event logs, DNS logs, and EKS audit logs.
