AWS Direct Connect (DX) Highlights

AWS Direct Connect:

Private connection to transfer data between AWS Cloud and on-premise data center

You need a local DX partner to using DX. You connect to the DX partner via fiber optic link. This is a physical link. In the physical link, you can create many virtual interfaces to connect to AWS VPC or AWS Services.

AWS DX support dedicated connection with 1Gbps and 10 Gbps

1Gbps or higher: Work with AWS Partner Network or network provider to connect DX location.

Less than 1Gbps: Work with AWS Partner Network who can create hosted connection for you.

AWS DX support hosted connection capabilities of 1, 2, 5, 10 Gbps.

Support AWS Transit Gateway, aside from configuring site-to-site VPN connections.

Common use cases:

Transfer large datasets

Hybrid cloud to satisfy regulatory requirements of private connectivity

Develop and run real-time application data feeds

Tech Specification

Virtual interfaces is a logical channel that divided from physical dx link. You must create a virtual interface to begin using your DX connection. There are 2 types of virtual interfaces:

Virtual Private interface: Connect to AWS VPC. One private virtual interface for each VPC or you can use AWS DX Gateway.

Virtual Public interface: Connect to AWS public services such as S3, DynamoDB

To access public resources on the remote AWS location, you have to setup public virtual interface and enable BGP session.

Autonomous System Number (ASN) are used to identify networks that present a clearly defined external routing policy to the Internet.

MTU (Maximum Transmission Unit):

Virtual private interface: 1500 or 9001 (jumbo frames)

Transit virtual interface for VPC transit gateway: 1500 or 8500 (jumbo frames)

Virtual public interface: does not support jumbo frames

LAG (Link Aggregation Group) group multiple DX connection into a single, managed connection.

All connection in a LAG has same connection bandwidth

Maximum connections in a LAG: 4

All connections in the LAG must terminate at the same DX endpoint

All connection is a LAG working in active/active mode

Only available for dedicated 1G or 10GB connections

DX Gateway is to use to connect multiple VPC in same or different AWS Regions via virtual private interface.

DX Gateway is global available resource

Enable to connect your on-premise data center to any AWS region (except China region).

Can associate up to 10 VPC in different accounts with DX Gateway. The accounts must be in same AWS payer account ID.

Monitoring

CloudTrail captures all API calls for DX as events

Setup CloudWatch alarms to monitor metrics.

You also can use tags for DX.

Pricing:

Network ports you use and data transfer over the connection

Pricing is per hour consumed per each port type.

Data transfer out will be charged per GB

Data transfer in is free in all locations

Tìm hiểu về LAG - Link Aggregation Groups

LAG hay còn gọi là Link Aggregation Group là một tính năng của AWS Direct Connect (DX). Sử dụng trong trường hợp có nhiều kết nối AWS DX giữa on-premise và AWS Cloud có thể gộp lại để có hiệu năng một đường tổng lớn.

Ví dụ: Có 02 đường DX 10Gbps, có thể gộp lại thành 1 đường 20Gbps.

Tuy nhiên để có thể cấu hình AWS LAG bạn cần đảm bao những điều kiện sau:

Tất cả link trong LAG phải ở active/active mode

Tất cả connection trong cùng LAG phải cùng bandwidth. Ví dụ: 1Gbps thì ko thể add một đường 10Gbps…

Số lượng DX connection tối đa mỗi LAG: 4

Tất cả DX Connection phải terminate trong cùng AWS DX Endpoint.

日本政府、ダウンタイムの調査を行うと発表 アマゾン ウェブ サービス（AWS）の東京AP-Northeast-1リージョンでネットワークの問題により、6時間以上にわたる障害が発生しました。 同社によると、ハイブリッドクラウドネットワーキングサービス「AWS Direct Connect」が、複数のネットワーク機器の問題により接続できない状態になったとのことです。 データセンター自体は停止しませんでしたが、この障害により、日本国内で広範囲に渡ってサービスが停止しました。 AWS Direct Connectは、ユーザー拠点からAWSへの専用ネットワーク接続を確立するクラウドサービスソリューションです。企業は、AWSと自社データセンター、オフィス、コロケーション環境との間に、プライベートな接続を構築することができます。 「この事象は、AP-Northeast-1リージョン内のすべての…
