Leading cloud migration projects has taught me that successful cloud adoption requires much more than just moving applications to different servers.
Lift-and-shift approaches provide quick migration paths but often fail to realize cloud benefits like elasticity, managed services, and cost optimization.
Re-architecting applications for cloud-native patterns enables better scalability and cost efficiency but requires significant development investment and organizational change.
Cost management becomes more complex with pay-per-use pricing models. Understanding resource usage patterns and optimization opportunities requires new financial planning approaches.
Security models shift from perimeter-based to identity-based approaches. Zero-trust architectures and cloud-native security services require different skills and processes.
Vendor lock-in concerns must be balanced against the benefits of using platform-specific managed services that reduce operational overhead.
Multi-cloud strategies provide vendor independence but increase complexity and may reduce the benefits of deep platform integration.
Skills development requirements affect entire organizations. DevOps practices, cloud architecture, and platform-specific knowledge become essential capabilities.
Governance and compliance frameworks must adapt to shared responsibility models where cloud providers handle infrastructure security while customers remain responsible for application security.
Migration planning requires detailed assessment of application dependencies, data relationships, and integration requirements that may not be well-documented.
Performance characteristics can change significantly in cloud environments due to shared infrastructure, network latency, and different storage systems.
The cultural shift toward treating infrastructure as code and embracing automation often proves more challenging than the technical migration itself.
