Azure Kubernetes Service
Pros
- + Free control-plane tier makes development and CI clusters genuinely cheap
- + Financially backed 99.95% API-server SLA on Standard tier with Availability Zones
- + Deep Azure integration: Entra ID RBAC, Monitor, Container Registry, DevOps pipelines, Arc hybrid
- + AKS Automatic removes most cluster operations for teams that want it
- + Upstream-conformant Kubernetes with GPU node pools and up to 5,000 nodes per cluster
Cons
- - Real lock-in to Azure identity, networking, storage, and monitoring beyond the portable YAML layer
- - Total cost is dominated by meters that are easy to underestimate (VMs, disks, log ingestion, egress)
- - Free tier has no SLA and is explicitly not meant for scale or high availability
- - Version support window forces regular upgrades unless you pay for Premium long-term support
- - Managed control plane is not a managed platform — node and workload operations remain yours on Standard
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
