EKS only gives you 99.9% uptime, and I'm uncertain as to whether you could achieve more than 99.9% uptime on your own by DIYing your cluster in a public cloud provider without doing multi-region.
To put that in perspective, three 9’s allows you about 9 hours of downtime a year, which will certainly require multi-region and a dedicated ops team.
Two and a half 9’s is a whole different story. We achieved about 20 hours of downtime last year even without HA on k8s bare metal in Alibaba cloud. But I’m uncertain whether that’s a feat we can repeat this year.
