In AWS, "PrivateLink" refers to a feature that allows you to privately connect your VPC (Virtual Private Cloud) to various AWS services and resources hosted by other AWS accounts, without exposing your network traffic to the public internet, essentially acting as a secure, private gateway between your VPC and other services within the AWS network; you can access these services using private IP addresses within your VPC, eliminating the need for public IP addresses or going through the public internet.
Key points about PrivateLink:
Private connectivity:
The primary benefit is that all communication happens within the AWS private network, ensuring secure data transfer.
VPC endpoints:
To connect to services via PrivateLink, you create "VPC endpoints" within your VPC which act as entry points to access the desired service.
Service providers:
You can also expose your own services hosted in your VPC as "VPC endpoint services" to other AWS accounts, allowing them to access your services privately.
No public IP needed:
You can access services using private IP addresses within your VPC, eliminating the need for public IP addresses.
