1. VPC Endpoint 与 PrivateLink 导论
时间范围：00:00–00:40
总结 / Summary
中文
本节从网关端点（Gateway Endpoint）转向由 VPC PrivateLink 提供支持的 VPC 端点（VPC Endpoint）。后续提到的 Endpoint 主要指 PrivateLink Endpoint，而不是仅适用于 Amazon S3 和 DynamoDB 的 Gateway Endpoint。
English
This section shifts from Gateway Endpoints to VPC endpoints powered by AWS PrivateLink. From this point forward, “endpoint” primarily means a PrivateLink-powered endpoint rather than the Gateway Endpoint type limited to Amazon S3 and DynamoDB.
Transcript
00:00 Okay, now that you understood VPC gateway endpoints, let's look at the more important part of the
00:06 endpoints that is VPC endpoint and private link.
00:10 And here onwards whenever we refer to the VPC endpoint please understand that we are not talking about
00:15 the gateway endpoints.
00:17 We are talking about the endpoints which are powered by AWS VPC private link, and it differs the way
00:24 it works as compared to the VPC gateway endpoint.
00:27 So let's now completely focus on VPC endpoint in context of the private link.
00:33 Okay.
00:34 So going back to this architecture, we already talked about the gateway endpoint to access Amazon S3
2. 架构定位：Interface Endpoint 的访问路径
时间范围：00:40–01:36
总结 / Summary
中文
接口端点（Interface Endpoint）会在使用者 VPC 内创建弹性网络接口（Elastic Network Interface, ENI）。工作负载可通过该私有入口访问 AWS 服务端点（AWS Service Endpoint），也可访问另一个 VPC 中由端点服务（Endpoint Service）公开的自建应用；本节重点讨论 Interface Endpoint。
English
An Interface Endpoint creates an Elastic Network Interface (ENI) inside the consumer VPC. Workloads use that private entry point to reach AWS service endpoints or privately published applications in another VPC through an Endpoint Service; the section focuses on Interface Endpoints.
Transcript
00:40 or DynamoDB from within your VPC.
00:44 But in the rest of this section let's focus on the interface endpoint which is actually powered by AWS
00:50 VPC private link.
00:52 And as you can see here, as you create the interface endpoint, it creates an Eni into your VPC.
00:58 And then you can get access to different AWS services endpoints as well as your own application which
01:05 might be hosted in another VPC.
01:08 Right.
01:08 So we are talking about two and three.
01:11 Now these are interface endpoints.
01:13 But in reality there are again additional types of endpoints which are powered by private link.
01:20 While in this section we will be focusing on interface endpoints only.
01:23 But just for your knowledge, you should also know that there are other types of the endpoints which
01:29 use private link feature of aws VPC.
01:33 Okay, so what's new in that space?
3. PrivateLink Endpoint 类型与新增能力
时间范围：01:36–04:39
总结 / Summary
中文
PrivateLink 可连接 AWS 服务、自建端点服务（通常位于网络负载均衡器（Network Load Balancer, NLB）之后）以及第三方 SaaS。除 Interface Endpoint 外，AWS 还提供资源端点（Resource Endpoint）和 VPC Lattice 的服务网络端点（Service Network Endpoint）。新能力包括 IPv4/IPv6 双栈与地址族转换、跨区域访问（Cross-Region Access），以及基于 IPv4 或 IPv6 的 UDP 流量。
English
PrivateLink can connect consumers to AWS services, customer-owned endpoint services commonly fronted by a Network Load Balancer (NLB), and third-party SaaS. In addition to Interface Endpoints, AWS provides Resource Endpoints and VPC Lattice Service Network Endpoints. Newer capabilities include IPv4/IPv6 support and translation, cross-Region access, and UDP over either address family.
Transcript
01:36 So if you look at this diagram the first block shows accessing AWS services which is interface endpoint.
01:42 Second is you are having your own services deployed inside a VPC front ended by network load balancer.
01:50 Now that becomes the endpoint service.
01:52 And that you can also access using the interface endpoint.
01:55 Now third type is the SaaS service.
01:57 So maybe you are consuming some SaaS application from third party provider.
02:02 Now they also expose their private services using the interface endpoint.
02:07 And then there are additional types of endpoints as I said for example resource endpoint and service
02:12 network endpoint.
02:14 So types of endpoint.
02:16 The most important is interface endpoint.
02:18 And that's what really came first.
02:20 But over the time and in the recent time rather AWS has launched something called Resource Endpoint
02:27 which allows you to access any VPC resource privately.
02:31 So for example, if you have RDS database inside your VPC and it is not exposed to the internet, you
02:38 can also access that using this resource endpoint.
02:42 Similarly, there is also service network endpoint which is a feature of VPC lattice.
02:48 And we have talked in detail about this in the VPC lattice section.
02:53 So in this section we are also not going to talk much about this service network endpoint.
02:58 As I said we will be primarily focusing on the interface endpoints.
03:03 Okay.
03:04 Other than that there is now support for both IPv4 and IPv6 traffic, which means that your client,
03:11 which is using the services through this interface endpoint, can have IPv4 or IPv6 traffic, and your
03:20 provider services could also be IPv4 or IPv6.
03:24 So all this translation from IPv4 to six or 6 to 4 is done using this interface endpoints.
03:32 So you don't need to really do that natting yourself.
03:36 Further, in 2024, Reinvent AWS announced that VPC interface endpoint can now be accessed across the
03:43 region.
03:44 And this is really exciting because until now, the scope of the endpoint was regional, which means
03:49 the VPC in which you create the endpoint should be in the same region as the service which you are accessing
03:55 using the endpoint.
03:56 So this is something new.
03:58 And now it also supports the UDP traffic over both IPv4 and IPv6.
04:04 Otherwise only TCP traffic was supported.
04:07 But now UDP traffic is also supported.
04:10 So these are the new features.
04:12 And at this point at least in 2025 I don't expect say Cross-region VPC endpoint related questions.
04:19 But over the time as the exam questions are refreshed, you might find these additional topics in the
04:25 exam.
04:26 Right.
04:27 So I hope it is clear what is VPC interface endpoint and all these additional features.
04:33 So just to reiterate we are talking about now VPC private link enabled endpoints.
4. VPC PrivateLink 的核心连接模型
时间范围：04:39–05:27
总结 / Summary
中文
使用者只需连接自己 VPC 中的 Interface Endpoint，底层 PrivateLink 会把流量私有地传送至 AWS Service Endpoint，或传送至由 NLB 支持的 Endpoint Service/SaaS Provider。使用者无需看到或管理提供方网络，后续课程将继续介绍 Interface Endpoint 的特性和进阶概念。
English
The consumer connects only to the Interface Endpoint in its own VPC. PrivateLink privately carries the traffic to an AWS service endpoint or to an NLB-backed Endpoint Service or SaaS provider, without exposing the provider network to the consumer. Later lectures build on this model with Interface Endpoint features and advanced concepts.
Transcript
04:39 And in that we are focusing on the VPC interface endpoint which allows you to access AWS services endpoints
04:48 or your own service which is hosted behind the network load balancer or any SaaS service provider service
04:55 which is again hosted behind the network Load balancer.
04:57 But you don't really see that.
04:59 What you see is VPC endpoint service to which you connect through this endpoint in your VPC, right.
05:06 So we'll focus mainly on this interface endpoint.
05:10 Okay.
05:10 So that was a quick introduction about VPC endpoints and Privatelink.
05:14 And now let's get into little more details about the VPC endpoints.
05:17 Some important features to know and some additional advanced concepts.
05:22 So that's it for this lecture.
05:23 And let's go to the next lecture.
05:25 Thank you.

本讲建立 VPC PrivateLink 的基础模型：Interface Endpoint 通过 VPC 内的 ENI 为 AWS 服务、自建服务和 SaaS 提供私有入口，并补充 Resource Endpoint 与 Service Network Endpoint 两种相关类型。重点更新包括 IPv4/IPv6、地址族转换、跨区域访问（Cross-Region Access）和 UDP 支持。
English
This lecture establishes the VPC PrivateLink model: an Interface Endpoint uses ENIs in the consumer VPC to provide private access to AWS services, customer services, and SaaS, alongside the newer Resource Endpoint and Service Network Endpoint types. Key updates include IPv4/IPv6, address-family translation, cross-Region access, and UDP support.
