Multi-rack and multiple logical AWS Outposts architecture considerations for resiliency

This article discusses architecture considerations for improving resiliency in AWS Outposts deployments across multiple racks and Outposts locations. Key strategies for enhancing workload availability include:

• Using multi-rack logical Outposts with rack-level spread placement groups
• Deploying multiple Outposts across different Availability Zones
• Implementing service-specific resiliency strategies for:
  • Amazon EC2: Auto Scaling groups across Outposts
  • Amazon RDS: Read replicas and multi-AZ deployments
  • Amazon EKS: Extended and local cluster configurations
  • Amazon S3: Object replication between Outposts

The article recommends connecting each Outpost to a unique Availability Zone and creating redundant service link connections to maximize high availability and minimize potential network disruptions.
