Key Takeaway
While AWS dominates with ~33% market share and generated $10.2 billion in Q2 2025 operating income, recent outages demonstrate the risk of single-provider dependency. Each alternative offers unique strengths—whether Microsoft’s enterprise integration, Google’s data analytics prowess, Oracle’s database optimization, IBM’s compliance focus, or Alibaba’s Asia-Pacific dominance.
Diversifying cloud infrastructure ensures business continuity, reduces vendor lock-in, and provides access to specialized capabilities tailored to specific workloads and geographic requirements.
