Does EKS fargate automatically provision it's nodes across multiple AZ's? If it does not do it automatically is it configurable to do so or is it a limitation of fargate and a potential uptime risk? A link to the official documentation supporting the answer would be very helpful.

Edit: this old issue seems to imply that while fargate is multi az (3) it does not guarantee cross az replica assignment. So you can't ensure your replica sets are running across az's https://github.com/aws/containers-roadmap/issues/824 and you have to use managed nodes to guarantees pods are running in different az's

CodePudding user response：

Fargate distributes the nodes across 2 or more az's acording to their sla https://aws.amazon.com/compute/sla/

however fargate does not automatically ensure replica sets are distributed across its nodes in different zones and may not be possible to guarantee at this time. https://github.com/aws/containers-roadmap/issues/824

This more recent ticket has it under consideration https://github.com/aws/containers-roadmap/issues/1324
