‫So now let's talk about AWS PrivateLink,
‫also from the VPC Endpoint Services family.
‫So how does that work?
‫Well, say you have a service that you run within AWS,
‫or say there is a vendor on the Marketplace,
‫and they run a service on their own account
‫within their own VPC.
‫And they want to expose a service to customers of AWS.
‫So to thousands of VPC, they need to have private access
‫to that service, to establish a connectivity.
‫You could, for example, use VPC peering,
‫but that doesn't scale, and it's not very secure.
‫What you want is use something else,
‫and that's something else is a Private Link.
‫So a Private Link allows you
‫to connect a service running within your VPC
‫to other VPCs directly and privately.
‫So it does not require VPC peering or internet gateway,
‫because it's from the private network,
‫or NAT or route tables or anything like this.
‫So let's go through a diagram.
‫Say, for example, you are talking to a vendor
‫on the AWS Marketplace, and they run application service.
‫So they have their own service that you wanna use
‫in their own VPC.
‫And you wanna have access to it from your own VPC
‫in your own accounts with your own consumer applications.
‫In that case, you're going to ask your vendor
‫to do a Private Link.
‫On their end,
‫they will have to create a Network Load Balancer
‫to expose that service.
‫And on your end,
‫you will create an Elastic Network Interface,
‫and then you will establish a Private Link between the two
‫so that you have private access
‫to their Network Load Balancer
‫and therefore to their service.
‫And all the internet traffic is actually not gonna go
‫through the public internet,
‫but it's actually gonna go through your private network.
‫And so therefore all communications will remain private.
‫And so for every new customer
‫that that third party will need,
‫all they will have to do is to create a new Private Link
‫for their customers, which is very easy to manage
‫and way more scalable.
‫So that's it, I hope you like this lecture,
‫and I will see you in the next lecture.
