 How to get access to a VPC in a different area through peering? in MuleSoft

MuleSoft CloudHub itself cannot directly access resources in a different VPC through peering using CloudHub configurations. However, you can achieve this functionality by implementing a hybrid approach involving:

1. VPC Peering:

• Establish VPC peering between your CloudHub VPC and the VPC in the different area where your desired resources reside. This creates a secure connection between the two VPCs, allowing them to communicate privately.

2. Options for Accessing Resources:

Here are two primary methods to enable MuleSoft applications in CloudHub to access resources in the peered VPC:

a) Bastion Host:

• Deploy a bastion host (e.g., a jump server) within your on-premises network or a peered VPC.

• Configure your MuleSoft application to connect to the bastion host first.

• The bastion host can then act as a secure gateway to access resources in the target VPC. This approach offers an additional layer of security as the MuleSoft application directly interacts only with the bastion host.

b. AWS Transit Gateway (Optional):

• If you're already using an AWS Transit Gateway in your environment, you can leverage it to simplify network connectivity.

• Attach both your CloudHub VPC and the target VPC to the Transit Gateway.

• This allows resources in both VPCs to communicate seamlessly through the Transit Gateway, eliminating the need for a separate bastion host.

Additional Considerations:

• Security: Implement proper security measures like firewall rules and access controls to restrict access to resources within the peered VPC.

• Network Latency: Be mindful of potential network latency introduced due to the inter-region communication. Optimize your application logic to minimize the impact on performance.

Here's a breakdown of the steps involved:

1. Configure VPC Peering: Establish peering between your CloudHub VPC and the target VPC using the AWS Management Console or AWS CLI.

2. Bastion Host Approach:

• Deploy a bastion host within your on-premises network or a peered VPC.

• Configure security groups on the bastion host to allow inbound connections from your CloudHub application and outbound connections to the target resources.

• Within your MuleSoft application, use connectors like SSH or API calls to interact with the bastion host. The bastion host can then access the desired resources in the target VPC.

3. AWS Transit Gateway Approach (if applicable):

• Attach both your CloudHub VPC and the target VPC to the existing AWS Transit Gateway.

• Ensure proper routing configurations are in place within the Transit Gateway to allow communication between the VPCs.

• Your MuleSoft application can directly interact with resources in the target VPC without requiring an intermediary jump server.

Important Note: While CloudHub provides functionalities like Anypoint VPC and Private Connectivity options, these are primarily intended for establishing secure connections between CloudHub and resources within the same region. Accessing resources in a different area through VPC peering requires additional configurations as mentioned above.
