In-Depth Analysis
Kubernetes
Container orchestration platform
Strengths
- +Industry standard
- +Highly scalable
- +Open source
Weaknesses
- -Complex setup
- -Steep learning curve
Key features
Value 70/100. Kubernetes itself is free and open source, but nobody runs Kubernetes for free.
Watch out: Engineer time is the largest cost. A Kubernetes platform team of 2-3 engineers costs $300K-$500K/year in salary. Even managed services require Kubernetes expertise for YAML manifests, Helm charts, networking, and debugging.
Docker
Container platform for developers
Strengths
- +Industry standard
- +Great documentation
- +Active community
Weaknesses
- -Resource intensive
- -Learning curve
Key features
Value 70/100. Docker Desktop is free for personal use and learning, but the moment you use it commercially in a company with 250+ employees or $10M+ revenue, you must pay.
Watch out: Commercial use mandate: companies with 250+ employees OR $10M+ annual revenue MUST buy a paid subscription to use Docker Desktop. The Personal tier is only free for individuals, education, non-commercial open source, and small businesses
Pricing: Kubernetes vs Docker
| Plan | Kubernetes | Docker |
|---|---|---|
