Cloud Migration Strategies: AWS vs Azure vs Google Cloud

Choosing the right cloud platform is one of the most consequential infrastructure decisions an organization can make. AWS, Microsoft Azure, and Google Cloud each offer distinct strengths, pricing models, and ecosystem advantages. This guide provides a framework for evaluating each platform against your organization's specific workloads, compliance requirements, and strategic priorities.

AWS: The Market Leader with Unmatched Breadth

Amazon Web Services holds approximately 32% of the cloud market and offers the broadest portfolio of services — over 200 fully featured products. AWS excels in compute flexibility, storage, and its mature partner ecosystem. Organizations with diverse workloads, startup DNA, or a need for cutting-edge services often find AWS the most capable platform.

• Largest global infrastructure footprint (33 regions)
• Most mature serverless and container offerings
• Strongest marketplace and ISV ecosystem
• Best-in-class ML/AI services (SageMaker, Bedrock)

Microsoft Azure: The Enterprise and Hybrid Champion

Azure's deepest advantage is its integration with the Microsoft ecosystem — Active Directory, Office 365, Teams, and Dynamics 365. For organizations already invested in Microsoft licensing, Azure offers significant cost synergies and seamless identity management. Azure also leads in hybrid cloud scenarios, with Azure Arc enabling consistent management across on-premises, multi-cloud, and edge environments.

• Native Azure AD integration for enterprise identity
• Azure Arc for hybrid and multi-cloud management
• Strong compliance portfolio (90+ certifications)
• Best choice for Microsoft-centric organizations

Google Cloud: The Data and AI Powerhouse

Google Cloud Platform punches above its market share weight in data analytics and AI/ML. BigQuery, Vertex AI, and Looker represent best-in-class capabilities for organizations with data-intensive workloads. GCP's network infrastructure delivers exceptional performance for global applications.

Migration Strategy: The 6 Rs Framework

Regardless of platform choice, successful cloud migrations follow a structured approach. The "6 Rs" framework — Rehost, Replatform, Repurchase, Refactor, Retire, Retain — provides a decision model for each application in your portfolio.

• Rehost: Lift-and-shift for speed and quick wins
• Replatform: Minor optimizations without code changes
• Refactor: Re-architect for cloud-native capabilities
• Retire/Retain: Decommission or keep on-premises as appropriate

The best cloud platform is the one that aligns with your workloads, team expertise, and strategic roadmap. Cendien's cloud practice helps organizations evaluate, migrate, and optimize across all major platforms — ensuring you get maximum value from your cloud investment.
