EKS vs GKE: how to choose

EKS and GKE are both managed Kubernetes, and the honest summary is that GKE does more for you and EKS gives you more to assemble. Google shipped Kubernetes and its managed service reflects that: node auto-provisioning, upgrade orchestration and a working default networking model arrive without much decision-making. EKS starts closer to bare Kubernetes and expects you to choose the CNI behaviour, the autoscaler, the ingress path and the add-on lifecycle.

That difference matters less than where the rest of your infrastructure lives. A cluster does not exist in isolation — it talks to a database, assumes a role, reads a secret and writes to object storage. Running Kubernetes in the cloud your data is not in means paying for egress and latency on every one of those calls, and running an identity bridge for the privilege.

So the real question is rarely "which cluster is better". It is whether the workload's dependencies are in AWS or in Google Cloud, and whether your team has more experience with IAM or with Google's project and IAM model.

Where the day-to-day difference shows up

ConcernEKSGKE
Node managementManaged node groups, or Karpenter for provisioning. Auto Mode reduces this if you adopt it.Node auto-provisioning is mature and default-adjacent. Autopilot removes nodes as a concept entirely.
UpgradesYou drive control plane and node group upgrades, and you own add-on compatibility.Release channels handle sequencing; you pick a channel and a maintenance window.
Pod networkingVPC CNI assigns real VPC IPs to pods — excellent for integration, and a subnet-sizing problem you must plan for.Alias IP ranges, sized when the cluster is created. Fewer surprises, less direct VPC addressability.
Workload identityIRSA or EKS Pod Identity maps a service account to an IAM role.Workload Identity Federation binds IAM roles to the Kubernetes service account principal directly, with Google service account impersonation as the fallback.
Cost shapePer-cluster control plane charge plus nodes you size and own.Per-cluster charge plus nodes, or Autopilot's per-pod resource pricing.

Autopilot is the real differentiator

GKE Autopilot is the one option with no close EKS equivalent in spirit: you stop managing nodes, Google sizes and patches them, and you are billed for what your pods request rather than for instances. For a team without a platform engineer it removes an entire category of work — node upgrades, capacity headroom, autoscaler tuning.

The trade is control. Privileged workloads, arbitrary DaemonSets, custom kernel settings and some observability agents are restricted or unavailable, and per-pod pricing can exceed well-packed self-managed nodes at scale. Autopilot suits application workloads with ordinary requirements; it is a poor fit for infrastructure-flavoured workloads that expect node access.

Frequently asked questions

Is GKE genuinely easier to operate than EKS?

Yes, out of the box, and the gap is narrowing. GKE's upgrade orchestration, node auto-provisioning and defaults mean fewer decisions before a cluster is production-ready. EKS has closed distance with Pod Identity, managed add-ons and Auto Mode, but it still assumes you will assemble more of the stack yourself. If ease of operation is the deciding factor and neither cloud is required, GKE wins it.

Can I run the same manifests on both?

Mostly yes — the workload API is identical. What does not port is the surrounding integration: IAM annotations on service accounts, ingress and load balancer annotations, storage classes, and anything referencing cloud-specific resources. Budget for the glue, not the Deployments. Keeping that glue in overlays rather than in base manifests makes the difference manageable.

Which is cheaper?

Control plane charges are close enough not to decide anything; node cost dominates and depends on how well you pack and what commitments you hold. The larger cost usually hides elsewhere — cross-cloud egress if your data is in the other provider, and idle capacity from over-provisioned node groups. Model those two before comparing sticker prices.

What about multi-cloud across both?

Running the same workload on both is a real strategy for a small number of organisations and an expensive mistake for most. You take on two identity models, two networking models, two upgrade cadences and a lowest-common-denominator platform. Choose it when a contract or a genuine availability requirement demands it, not as insurance against a lock-in that mostly lives in the data layer anyway.
