Kubernetes Cloud Services Complete Comparison: EKS vs GKE vs AKS [2025 Update]

Running Kubernetes yourself is complicated. Most enterprises choose to use cloud managed services.

But AWS, Google, and Azure all have their own Kubernetes services. Which should you choose?

This article will comprehensively compare the three major cloud Kubernetes services to help you make the right choice.

For a basic introduction to Kubernetes, see Kubernetes Complete Guide.

Overview of Three Major Cloud Services

Let's first introduce the three services:

Cloud	Service Name	Full Name
AWS	EKS	Elastic Kubernetes Service
Google Cloud	GKE	Google Kubernetes Engine
Azure	AKS	Azure Kubernetes Service

Why Use Managed Services?

Running Kubernetes yourself means handling:

Item	Self-managed	Managed Service
Control Plane maintenance	Your job	Cloud handles it
etcd backup	Your job	Automatic
Version upgrades	Your job	Semi-automatic/automatic
HA setup	Your job	Built-in
Security patches	Your job	Automatic

Conclusion: Unless you have special requirements, managed services save time and effort.

Market Share

According to 2024 surveys:

Service	Market Share
AWS EKS	~45%
Google GKE	~25%
Azure AKS	~20%
Others	~10%

EKS has the largest share, but this is mainly because AWS has higher overall market share. GKE leads in Kubernetes purity and features.

AWS EKS Detailed Overview

Basic Introduction

EKS (Elastic Kubernetes Service) is AWS's managed Kubernetes service.

Features:

Feature	Description
AWS integration	Deep integration with IAM, VPC, ALB, and other services
Stability	AWS SLA guarantee
Ecosystem	Largest cloud ecosystem

Advantages

1. AWS Ecosystem Integration

If you're already heavily using AWS, EKS integration is very convenient:

Integrated Service	Purpose
IAM	Authentication and authorization
VPC	Network isolation
ALB/NLB	Load balancing
ECR	Container image registry
CloudWatch	Monitoring and logging
Secrets Manager	Secrets management

2. EKS Anywhere

Can run EKS in on-premises data centers for hybrid cloud.

3. Fargate Support

Serverless option, no need to manage Nodes:

# Using Fargate Profile
apiVersion: v1
kind: Pod
metadata:
  name: my-app
  namespace: fargate-namespace  # Namespace matching Fargate Profile
spec:
  containers:
  - name: app
    image: my-app:1.0

Disadvantages

1. Control Plane Charges

$73 per month per cluster, whether you use it or not.

2. Learning Curve

AWS's IAM and VPC setup is already complex; adding EKS makes it more so.

3. Slow Version Updates

EKS's Kubernetes version is usually several months behind upstream.

Pricing Structure

Item	Cost
Control Plane	$0.10/hour (~$73/month)
Worker Nodes	Per EC2 instance pricing
Fargate	Per vCPU and memory
Network traffic	Per AWS standard rates

Example estimate (small cluster):

• Control Plane: $73/month
• 3 t3.medium Nodes: ~$90/month
• Total: ~$163/month

Google GKE Detailed Overview

Basic Introduction

GKE (Google Kubernetes Engine) is Google Cloud's managed Kubernetes service.

Kubernetes itself was developed by Google, so GKE typically leads technologically.

Features:

Feature	Description
Technology leader	Fastest support for latest K8s features
High automation	Auto-upgrade, auto-repair
Autopilot mode	Fully managed, don't even manage Nodes

Advantages

1. Free Control Plane (Standard Mode)

GKE Standard's Control Plane is free. This is the biggest advantage.

2. Autopilot Mode

No need to manage Nodes at all, just deploy Pods:

Item	Standard	Autopilot
Node management	You manage	Google manages
Resource allocation	You configure	Auto-optimized
Security patches	Semi-automatic	Fully automatic
Billing method	Per Node	Per Pod resources

3. Fast Version Updates

GKE usually supports new Kubernetes versions very quickly after release.

4. Strong Automation Features

Feature	Description
Auto-upgrade	Can set maintenance windows for automatic upgrades
Auto-repair	Nodes automatically repaired when abnormal
Auto-scaling	Both cluster and Pod scaling supported

Disadvantages

1. Smaller Google Cloud Ecosystem

Compared to AWS, Google Cloud's overall services and market are smaller.

2. Regional Limitations

Some regions have fewer availability zones.

3. Autopilot Limitations

• Can't use DaemonSet
• Some advanced features are limited
• Longer cold start time

Pricing Structure

Item	Standard	Autopilot
Control Plane	Free	$0.10/hour
Worker Nodes	Per GCE pricing	N/A
Pod resources	N/A	Per vCPU/memory

Example estimate (small cluster, Standard):

• Control Plane: $0
• 3 e2-medium Nodes: ~$75/month
• Total: ~$75/month

Almost half the cost of EKS!

Azure AKS Detailed Overview

Basic Introduction

AKS (Azure Kubernetes Service) is Microsoft Azure's managed Kubernetes service.

Features:

Feature	Description
Enterprise integration	Deep Active Directory integration
Windows containers	Best Windows container support
Hybrid cloud	Azure Arc support

Advantages

1. Free Control Plane

Like GKE Standard, AKS Control Plane is free.

2. Azure AD Integration

If your company uses Microsoft 365 or Azure AD, integration is very convenient:

# Login to AKS with Azure AD
az aks get-credentials --resource-group myRG --name myAKS
# Will automatically use Azure AD identity

3. Best Windows Container Support

Need to run Windows containers? AKS is the best choice:

Feature	AKS	EKS	GKE
Windows Node	✅ Native support	✅ Supported	✅ Supported
Integration level	Best	Medium	Medium
.NET optimization	✅	❌	❌

4. Azure Arc

Can use Azure to manage Kubernetes anywhere:

• On-premises data centers
• Other clouds
• Edge devices

Disadvantages

1. Complex Interface

Azure Portal operations are more cumbersome.

2. Documentation Quality

Compared to AWS and GCP, Azure documentation is sometimes unclear.

3. Some Features Delayed

New Kubernetes features sometimes supported later than GKE.

Pricing Structure

Item	Cost
Control Plane	Free
Worker Nodes	Per Azure VM pricing

Detailed Pricing Comparison

Pricing is an important selection factor. Let's look at detailed comparisons.

Control Plane Costs

Service	Monthly Cost
EKS	$73
GKE Standard	$0
GKE Autopilot	$73
AKS	$0

EKS charges for each cluster, making multi-cluster environments expensive.

Example Scenario Cost Estimates

Scenario 1: Small Development Environment

3 Nodes, 2 vCPU / 4GB RAM each

Service	Monthly Estimate
EKS	$73 + $90 = $163
GKE	$0 + $75 = $75
AKS	$0 + $85 = $85

Scenario 2: Medium Production Environment

10 Nodes, 4 vCPU / 16GB RAM each, plus load balancing

Service	Monthly Estimate
EKS	$73 + $800 + $20 = $893
GKE	$0 + $700 + $18 = $718
AKS	$0 + $750 + $18 = $768

Scenario 3: Large Multi-Cluster

5 clusters, 20 Nodes each

Service	Monthly Estimate
EKS	$365 + $8,000 = $8,365
GKE	$0 + $7,000 = $7,000
AKS	$0 + $7,500 = $7,500

Hidden Costs

Don't just look at Control Plane—consider these too:

Item	Description
Network traffic	Cross-region and outbound traffic charged
Load balancers	Each LoadBalancer Service costs money
Storage	PersistentVolume costs
Logs/Monitoring	Expensive when data volume is large

Cost optimization suggestions:

Suggestion	Estimated Savings
Use Spot/preemptible instances	60-80%
Properly set resource requests/limits	20-30%
Use Cluster Autoscaler	10-20%
Consolidate small clusters	Reduce Control Plane costs

FAQ: Common Questions

Q1: Haven't used any cloud, which should I choose?

Recommend GKE.

Reasons:

• Free Control Plane
• Autopilot is simplest
• Most advanced technology
• Clear documentation

Q2: Does free Control Plane really matter?

Yes, especially for multi-cluster.

Cluster Count	EKS Annual Cost	GKE/AKS Annual Cost
1	$876	$0
5	$4,380	$0
10	$8,760	$0

With dev, test, and prod clusters each, EKS costs an extra $2,600/year.

Q3: GKE Autopilot vs EKS Fargate—which is better?

Item	GKE Autopilot	EKS Fargate
Maturity	More mature	Mature
Pricing	Lower	Higher
Limitations	Fewer	More
Cold start	Yes	Yes

Overall, GKE Autopilot is better.

Q4: Can I do multi-cloud?

Yes, but it adds complexity.

Multi-cloud solutions:

• Anthos (Google): Manage any K8s
• Azure Arc (Microsoft): Manage any K8s
• EKS Anywhere (AWS): Only EKS-compatible clusters

Recommendation: Unless there's a clear need, focus on a single cloud first.

Q5: Are there cheaper options than these three?

Yes.

Service	Features
DigitalOcean DOKS	Cheaper, good for small projects
Linode LKE	Cheaper, good for small projects
Vultr VKE	Cheaper, good for small projects
Civo	K3s-based, cheap and fast

But these services don't have the ecosystem and enterprise features of the three major clouds.
