OKE vs EKS vs AKS

Managed Kubernetes has become the default way to run containers, and all three major clouds offer it: OKE on OCI, EKS on AWS, and AKS on Azure. They all run upstream Kubernetes, so your manifests are portable, but they differ on what the control plane costs, how nodes work, how networking is wired, and how much operational help you get. This article compares the three honestly so the platform decision rests on more than which cloud you already use.

It is part of our OCI vs hyperscalers series and builds on our pillar OCI Kubernetes Engine: the complete guide.

They all run real Kubernetes

The most important thing to say first is that all three are conformant Kubernetes, so your workloads, Helm charts, and operators move between them with little change. The lock in lives not in Kubernetes itself but in the surrounding services you wire to it, such as load balancers, storage classes, identity, and registries. Keep those interfaces clean and the cluster stays portable across all three.

Control plane cost

This is the sharpest difference. OKE offers a free control plane on its basic tier and a paid enhanced tier with stronger SLAs and higher limits, so small clusters can run without a per cluster control plane fee. EKS charges an hourly fee per cluster control plane. AKS has historically offered a free control plane with a paid uptime SLA tier. For organisations running many clusters, the per cluster control plane charge on EKS adds up, and OKE's model is the most economical at the base.

Node and compute options

OKE lets you run worker nodes on the full OCI Compute range, including Arm Ampere and bare metal, and offers virtual nodes for a serverless style of pod hosting. EKS pairs with the wide instance range and Fargate for serverless pods. AKS uses the Azure VM range and supports virtual nodes through container instances. OKE's standard bare metal option is distinctive for performance sensitive container workloads, and its Arm pricing is attractive.

Networking and operations

All three integrate the cluster with the cloud's own virtual network, load balancers, and identity. EKS has the deepest ecosystem of add ons and the largest pool of experienced engineers. AKS integrates tightly with Azure identity and tooling. OKE benefits from OCI's flat high bandwidth network and low egress, which keeps cluster to cluster and outbound traffic cheap, a real factor for data heavy services. For day to day operations the three are broadly comparable once set up.

Choosing between them

Bringing it together

OKE, EKS, and AKS all run genuine Kubernetes, so choose on control plane cost, node options, egress, and ecosystem rather than fearing lock in. OKE leads on control plane economics, bare metal nodes, and egress, while EKS leads on ecosystem breadth.
