Connectivity Suggestions for AWS Outposts and SCADA Control Systems Architecture

Correct Answer - A, D.

While AWS Outposts is provisioned, it requires connectivity to public AWS ranges in the nearest AWS region either over the internet or AWS Direct Connect Public VIF.

Service Link path can be deployed for this serving two things- Management traffic to the AWS Outpost & traffic from AWS Outposts to other services in AWS cloud.

Option B is incorrect as Local Gateway Path is for traffic between AWS Outpost & On-premises network & not for management traffic towards parent region.

Option C is incorrect as For Management traffic, AWS Outposts should be able to connect with AWS public subnets.

For this, a Public VIF needs to be created with AWS Direct Connect & Not private VIF.Option E is incorrect as this advertisement is required for connectivity from AWS Outpost to on-premises subnets.

To provide low latency to application servers deployed in AWS infrastructure, the tractor manufacturing firm plans to deploy AWS Outposts in their IT facility at manufacturing plants. The AWS Outposts is a fully managed service that extends AWS infrastructure, services, APIs, and tools to any customer on-premises facility.

To ensure there is no impact on connectivity from manufacturing plants to other servers deployed in the VPC, the following two suggestions can be implemented:

1. Create a Service Link Path: This involves creating a private connection between the AWS Outpost and the nearest AWS region using AWS PrivateLink. With this solution, the traffic from the manufacturing plant will flow through the AWS Outpost and to the nearest AWS region for management traffic. AWS PrivateLink is a highly available, scalable technology that enables private communication between VPCs, AWS services, and on-premises applications using private IP addresses.

2. Create Local Gateway Path: This involves creating a local gateway in the VPC and configuring it to communicate with the AWS Outpost. The local gateway acts as a router and enables communication between the manufacturing plant and the AWS Outpost. The local gateway can be configured to route traffic from the manufacturing plant to the AWS Outpost and vice versa. This solution can be implemented using the AWS Transit Gateway.

Additionally, to communicate with AWS IP ranges, the following suggestions can be considered:

1. Create a Private VIF over AWS Direct Connect: This involves establishing a private virtual interface (VIF) over AWS Direct Connect to connect the manufacturing plant to the nearest AWS region. This solution provides a dedicated, private connection to AWS infrastructure and can be used to access AWS services, including AWS Outposts.

2. Advertisement of AWS Outposts Subnet to Local gateway: This involves advertising the AWS Outpost subnet to the local gateway in the VPC. By doing this, the local gateway will be aware of the IP range used by the AWS Outpost and can route traffic accordingly.

Using the internet link to communicate with AWS IP ranges is not recommended as it may not provide the required low latency and security for the SCADA control systems architecture.
