Private VIF on Direct Connect: A private virtual interface (VIF) is used to establish a private connection between your data center and your VPC over AWS Direct Connect. This allows traffic to remain within the private network.

Amazon S3 Gateway Endpoint: A gateway endpoint provides a scalable and highly available way to privately access Amazon S3 without requiring an internet gateway or NAT gateway. Gateway endpoints are more cost-effective than interface endpoints for accessing S3, especially for high-volume data transfers like application logs.

This solution provides a scalable and flexible architecture that accommodates future growth while ensuring connectivity between regions and locations.

New Direct Connect Connection in London: Establishing a Direct Connect connection for the London office provides a high-performance, private, and reliable connection between the office and AWS.

Use the Existing Direct Connect Gateway: By attaching the new Direct Connect connection to the existing Direct Connect gateway, the solution leverages the existing infrastructure, reducing operational complexity.

Transit Gateway in eu-west-2: The transit gateway in eu-west-2 enables centralized routing and connectivity management for multiple VPCs in that Region.

Transit Gateway Peering: Peering the transit gateways inus-east-1andeu-west-2ensures seamless private connectivity between the regions, allowing users in the US and London to access workloads in both regions.

This design ensures low operational effort because it avoids creating and managing multiple individual VPN connections. It also supports future growth by allowing additional VPCs, regions, or office locations to connect with minimal configuration changes.

To resolve the issue of intermittent connections for traffic that crosses Availability Zones after configuring routing for traffic inspection between VPCs using a transit gateway and EC2 instances with IDS services in a shared services VPC, a network engineer should modify the transit gateway VPC attachment on the shared services VPC by enabling appliance mode support (Option B). This will ensure that traffic is routed to the same EC2 instance for stateful inspection and prevent intermittent connections.
