EKS • Certified Kubernetes distribution • OSS components available as EKS-Distribution • Can be run in Cloud or on-prem • Integrates well with AWS services for AWS customers • Enables Hybrid, and multi cloud workloads • High availability, security, resilience, and Fault tolerance "across AZs" • Undifferentiated heavy lifting

Slide 29

Slide 29 text

Why EKS? - CNCF certified distribution - can enable Hybrid, and multi cloud workloads - Integrates well with AWS managed services model - HA and Fault tolerance "across AZs" - Fully managed control plane ( self-healing, upgrades, patching)
