A company wants to leverage a best-of-breed approach for their application stack. They plan to use OCI for its Autonomous Database, Azure for its container orchestration (AKS), and AWS for its object storage (S3). Considering cost optimization and minimizing data egress charges, which strategy is the MOST efficient for transferring large datasets between these services?

Goal: Efficient, cost-optimized data transfer minimizing egress charges.
Option A: Public internet incurs high egress costs—incorrect.
Option B: Hub-and-spoke doubles egress/ingress charges—less efficient.
Option C: Third-party platform at peering points reduces egress by leveraging direct connections— correct.
Option D: Storage Gateway is for hybrid, not multicloud efficiency—incorrect. Conclusion: Option C is the most efficient strategy. Oracle states: "A third-party integration platform at peering points minimizes egress charges by using direct interconnects for multicloud data transfers.” This validates Option C.
