Introduction to AWS PrivateLink and its use cases

In this recipe, we will learn about AWS PrivateLink. We will also learn about the use cases of AWS PrivateLink.

Recipe Objective - Introduction to AWS PrivateLink and its use cases?

The AWS PrivateLink is a widely used service and is defined as a link that provides private communication between VPCs, AWS services, and users on-premises networks. AWS PrivateLink makes it simple to connect 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 their virtual network appliances or custom traffic inspection logic by powering Gateway Load Balancer endpoints. AWS PrivateLink allows users to use private IP addresses in their VPC to connect to some AWS services, services hosted by other AWS accounts (referred to as endpoint services) and supported AWS Marketplace partner services. AWS PrivateLink is also defined as a scalable and highly available solution that allows users to connect their VPC to services privately as if they were in your VPC. To allow communication with the service from their private subnets, users don't need to use an internet gateway, NAT device, public IP address, AWS Direct Connect connection, or AWS Site-to-Site VPN connection. As a result, users have complete control over which API endpoints, websites, and services their VPC may access.

Benefits of Amazon PrivateLink

  • With AWS PrivateLink, users can securely and scalable connect their 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. users can utilise private IP connectivity to make the services appear as if they were hosted on their private network. Users may also associate security groups with interface endpoints and attach an endpoint policy to them, allowing users to govern who has access to a specific service. The same security, scalability, and performance are delivered via AWS connections supported by PrivateLink, such as interface VPC endpoints and Gateway Load Balancer endpoints and thus provide security to the network. There are no firewall rules, path definitions, or route tables required to connect services across different 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 the global network with AWS PrivateLink since it simplifies the network design and thus simplifies the network management.

Use cases of AWS PrivateLink

    • It provides a use case for accessing Saas applications safely

Many APN partners use AWS to provide SaaS services to their customers, such as log analytics and security scanning. SaaS vendors place agents or clients in their customers' virtual private clouds (VPCs) to generate and deliver data back to them. Customers must choose between permitting Internet access from their VPC, which puts the VPC resources at risk, and not using these applications at all when employing SaaS applications. Users can connect to AWS services and SaaS apps from the VPC in a private, secure, and scalable manner using AWS PrivateLink. Because users are the only ones who can connect to a service and are protected against unwelcome communication from the service provider. IP address.

    • It provides a use case to ensure compliance with regulatory requirements

Preventing sensitive data from travelling over the Internet, such as customer records, helps users stay in compliance with rules like HIPAA, EU/US Privacy Shield, and PCI. Customers in the financial services, healthcare, and government sectors will benefit the most from this. AWS PrivateLink keeps traffic between AWS resources, VPCs, and third-party services on the Amazon network, where it is subject to strict security and compliance restrictions. This involves adhering to conventional financial regulations such as the SEC Rule 17a-4(f) and the Japanese FICS.

    • It provides a use case for moving to a hybrid cloud

Over AWS Direct Connect or AWS VPN, on-premises applications can connect to service endpoints in Amazon VPC. The traffic will be directed to AWS services via AWS PrivateLink, while the network traffic will remain within the Amazon network. AWS PrivateLink allows SaaS vendors to deliver services that appear and behave as if they were hosted on a private network. These services are provided in a highly available and scalable manner via AWS Direct Connect and AWS VPN from both the cloud and on-premises.
