Conclusion

There is no universal “best” cloud provider for Linux workloads. Your choice depends on your specific requirements, existing technology investments, and long-term cloud strategy.

AWS dominates in market share and service breadth. It’s the safest choice for enterprise deployments and offers the most mature ecosystem. If you’re starting fresh and need maximum flexibility, AWS is often the default choice.

Azure excels in hybrid scenarios and Microsoft integration. For organizations with significant Windows Server, SQL Server, or Office 365 investments, Azure provides the best total cost of ownership and integration benefits.

GCP offers the best developer experience and data analytics. For data-driven applications, machine learning, and Kubernetes-native deployments, GCP provides superior tooling and innovative features.

Many successful organizations use a multi-cloud strategy, leveraging each provider’s strengths for different workloads. As your infrastructure grows, you’ll likely benefit from understanding all three platforms and making informed decisions for each specific application.

Start with evaluating your immediate needs, estimated costs, and existing technology investments. Then choose the platform that aligns best with your current requirements, with the flexibility to expand to other providers as your needs evolve.
