Multi-cloud strategy has evolved from an option into a business imperative. By distributing workloads across providers like AWS, Azure, and Google Cloud, organizations eliminate single points of failure, reduce vendor lock-in, and access best-of-breed services for compute, AI/ML, and compliance. But building a resilient multi-cloud architecture requires careful planning around cost management, security, interoperability, and governance. From workload placement decisions to avoiding common pitfalls like hidden data egress fees and skill fragmentation, a well-executed multi-cloud approach delivers the agility and resilience modern enterprises demand.
