Direct Connect Best Practices
Direct Connect establishes high-speed, low-latency, stable, and secure dedicated network connections that connect your on-premises data center to the cloud.
You can use Direct Connect together with other cloud services to set up networks flexibly. You can refer to the best practices provided here for typical networking solutions.
Solution |
Example Scenario |
Cloud Services |
Description |
---|---|---|---|
Connecting an on-premises data center to VPCs in the same region |
Using a single Direct Connect connection: |
|
You can use a single connection with a virtual gateway associated to connect an-premises data center to a VPC and leverage the large bandwidth and private connectivity for fast, secure, stable data transmission |
|
To improve the network performance and reliability, you can deploy two connections to connect an on-premises data center to the VPC. The two connections work in load balancing mode.
|
||
|
You want to ensure high reliability of the hybrid cloud network, while enjoying the following benefits:
You can create two connections that work in an active/standby pair. If the active connection becomes faulty, the standby one will automatically take over, which minimizes service interruptions. |
||
|
You can create a single standard connection with multiple virtual gateways associated to access different VPCs. This enables end-to-end route isolation for different services. |
||
|
After you connect an on-premises data center to a VPC using Direct Connect, you can use VPC Peering to peer this VPC with other VPCs in the same region, so that the on-premises data center can access all connected VPCs. |
||
Connecting an on-premises data center to a VPC in the same region using Direct Connect and Enterprise Router |
Setting Up a Hybrid Cloud Network Using Enterprise Router and Direct Connect Global DC Gateway |
|
Suppose your enterprise has deployed two VPCs in a region. The two VPCs need to communicate with each other and communicate with your on-premises data center through a global DC gateway. |
|
An enterprise router enables dynamic route selection and switchover between connections that work in load balancing mode. This expands the network bandwidth, increases the network throughput, improves network performance, and ensures high reliability. By attaching global DC gateways to enterprise routers, you can set up a large-scale hybrid cloud network that meets your communication requirements. |
||
|
To improve the reliability of the hybrid cloud network and reduce costs, you can create two connections that work in an active/standby pair and use an enterprise router for dynamic route selection and switchover between the connections. If the active connection becomes faulty, the standby one will automatically take over, which minimizes service interruptions. |
||
Using a public NAT gateway and Direct Connect to accelerate Internet access |
Using a Public NAT Gateway and Direct Connect to Accelerate Internet Access |
|
You can use Direct Connect to connect your on-premises data center to the cloud and then buy a public NAT gateway to allow on-premises servers to access the Internet by setting SNAT rules or provide publicly accessible services by setting DNAT rules. |
Allowing on-premises servers to access cloud services |
Allowing On-Premises Servers to Access Cloud Services Using Direct Connect and VPC Endpoint |
|
You can create a connection to connect your on-premises data center to the cloud and then use VPC Endpoint to access cloud services over a private network. This enables faster access and reduces costs. |
