Implementing network traffic inspection on AWS Outposts rack

This article discusses how to implement network traffic inspection on AWS Outposts rack using a centralized firewall instance. It presents an architecture that allows routing traffic from on-premises networks and VPCs on the Outpost to the firewall for inspection.

Specifically, the article covers:

• The overall architecture, which uses multi-VPC Elastic Network Interface (ENI) attachments to connect a centralized firewall instance to multiple VPCs and the on-premises network
• Selecting and sizing the firewall instance based on performance requirements and available instance types on the Outpost
• Attaching remote ENIs from other VPCs to the firewall instance
• Updating VPC and Local Gateway route tables to route traffic through the firewall
• Considerations for fault tolerance using Auto Scaling groups and placement groups
• Conclusion highlighting the benefits of the proposed architecture
