Direct Connect Overview
AWS Direct Connect is a service that enables dedicated and private network connections between your datacenter, office, or colocation environment and Amazon Web Services (AWS). These connections bypass the public Internet, providing a more reliable and consistent connection with higher bandwidth capacity and reduced latency. Direct Connect connections can be established using either a 1 Gbps or 10 Gbps network port at one of the many AWS Direct Connect locations worldwide.
Guide: AWS Direct Connect Overview
AWS Direct Connect is a cloud service solution that establishes a dedicated network connection from your premises to AWS. It is important as it provides a more secure and consistent network experience than internet-based connections.
Understanding AWS Direct Connect:
It provides two types of connections: dedicated connections (1 Gbps and 10 Gbps) and hosted connections (50 Mbps to 500 Mbps). It uses industry standard 802.1q VLANs to maintain separation between multiple connections on the same physical cable.
How it works:
You connect your on-premises network to an AWS Direct Connect location via a standard ethernet fiber-optic cable, and then to AWS Cloud through a private network connection.
Exam Tips:
In examination questions about AWS Direct Connect, key points to remember include:
- AWS Direct Connect is not a VPN. It does not involve any encryption inherently.
- AWS Direct Connect does not connect to resources within VPC by default, VPC must be specified.
- Multi-account AWS Direct Connect connections are possible via Direct Connect gateway.
- Understand difference between associated VIF (Virtual Interface) and dedicated VIF. Always read the question carefully to decide whether it pertains to a connectivity issue, security concern, or cost-saving strategy.
Ultimately, understanding the AWS Direct Connect at a high level, its benefits, use cases and features will help you to answer the questions correctly during your exam.
