Act as a Senior Solutions Architect. Design a distributed microservices architecture for a global fintech platform expected to handle 100,000 transactions per second (TPS) with a latency of under 100ms. Your design must address the following: 1. Data consistency models across geographically distributed databases (e.g., using CRDTs or eventual consistency). 2. Handling of network partitions and fault tolerance (e.g., Raft consensus). 3. Security measures for PII and PCI-DSS compliance. 4. A deployment strategy using Kubernetes. Provide a high-level diagram description and a justification for your technology stack choices (e.g., Go vs Java, Kafka vs Pulsar).
