Cost Comparison
Cloud pricing is complex and varies significantly based on your specific workload. Here are typical cost differences:
AWS Pricing
- • Most mature pricing models
- • Savings plans can materially reduce spend
- • Complex but flexible
- • Higher data transfer costs
Azure Pricing
- • Hybrid benefit for Windows can significantly reduce spend
- • Competitive for Windows workloads
- • Similar to AWS for Linux
- • Lower data transfer costs
GCP Pricing
- • Sustained use discounts (automatic)
- • Competitive compute pricing
- • Per-second billing (vs per-hour)
- • Often competitive total costs for analytics-heavy workloads
Cost Comparison Notes
Costs vary significantly based on workload type, region, discount programs, and architecture decisions. We recommend using each provider's pricing calculator and running actual benchmarks for your specific requirements.
Provider portfolios and regional footprints change frequently; validate current service counts and availability before final selection.

Migration Considerations
Multi-Cloud Strategy
Using multiple providers can provide resilience and leverage best-of-breed services, but adds significant operational overhead.
Best for: Large enterprises with dedicated cloud teams. Not recommended for startups or small teams.
Switching Costs
Migrating between cloud providers typically is a significant investment and often spans multiple quarters depending on architecture complexity, data gravity, and dependency mapping.
Choose carefully - switching later is expensive and disruptive.
Team Skills
Consider your team's existing skills. AWS talent pools are often deeper in many markets, but local availability varies by region and specialization.
Training timeline: 3-6 months to build proficiency on a new cloud platform.
