Pricing Comparison
Compute (Virtual Machines)
Prices vary by region and instance type, but generally:
- GCP: Often 10-20% cheaper for equivalent specs
- AWS: Premium pricing, extensive savings options
- Azure: Competitive, especially with EA discounts
Savings Options
- AWS: Reserved Instances, Savings Plans, Spot

Decision Framework
Choose AWS if:
- You need the widest service selection
- You want the most mature ecosystem
- You're building complex architectures
Choose Azure if:
- You're a Microsoft shop (O365, Windows Server, AD)
- You need hybrid cloud capabilities
- You have existing Microsoft licensing
Choose GCP if:
- Data analytics is your primary workload
- You're building ML/AI applications
- Kubernetes is your deployment platform
Multi-Cloud Strategy
Many organizations use multiple clouds:
- Avoid vendor lock-in
- Leverage best-of-breed services
- Meet data residency requirements
However, multi-cloud adds complexity. Start with one platform and expand strategically.
Conclusion
There's no universally "best" cloud platform—the right choice depends on your specific needs, existing infrastructure, and team expertise. Consider starting with a proof-of-concept on your top candidate before committing.
