Amazon EKS
Pros
- + AWS-managed control plane across three AZs: no etcd, API server or upgrade operations
- + Upstream-conformant Kubernetes — standard manifests, operators and CNCF tooling work unchanged
- + Public, simple cluster fee ($0.10/hour) with no per-seat charges and no overage premiums on usage
- + Choice of EC2 managed node groups (including GPU and Graviton), Fargate serverless pods or Auto Mode
- + Deep AWS integration: IAM auth, VPC networking, EBS/ECR, Shield Standard DDoS protection, 39 regions
Cons
- - Extended support jumps to $0.60/hour per cluster after 14 months if versions are not upgraded
- - Total cost dominated by compute, storage and inter-AZ data transfer; bills are hard to forecast
- - Real AWS coupling through IAM, CSI drivers and ingress controllers despite Kubernetes conformance
- - Human support requires paid AWS Support plans on top of the platform costs
IBM Cloud
Pros
- + IBM Z (mainframe) and Power Virtual Server integration that no commodity host offers
- + Credit-backed 99.99% SLA on Virtual Server for VPC with multizone regions of three or more separate data centers
- + Ten instance profile families including Confidential Computing and storage-optimized shapes
- + Bare metal, spot-style transient servers, reserved capacity, and hourly billing in one contract surface
- + Free Lite account plus generous rotating new-account credits for trials
Cons
- - Two overlapping platforms (Classic and VPC) with different APIs, images, and pricing
- - Roughly 10x the monthly cost of value leaders for a comparable 2-vCPU VM
- - DDoS scrubbing is a separate paid product (Cloud Internet Services)
- - Metered extras (boot volume, egress, load balancers) make cost prediction work
- - Base support tier is not the enterprise support IBM's reputation implies
