A large e$-$commerce company wants to implement a system for their marketplace where all data related to products, transactions, user profiles, and communications are stored and managed in one central location. The company's primary goal is to have strict control over security, compliance, and user interactions due to the sensitive nature of the data involved, including personal and payment information. The system should enable real$-$time monitoring of all transactions, communications between buyers and sellers, and immediate processing of any flagged activities for security or policy breaches.

The organization prefers a streamlined architecture that minimizes latency within its data center to ensure rapid data processing for search queries, payments, and updates to user accounts. This architecture should also allow the administrators to enforce uniform policy updates, implement immediate bug fixes, and conduct direct data backups with minimal redundancy across the network. Moreover, in case of potential legal investigations, the company wants to ensure they can retrieve any transaction record or communication history directly without relying on separate servers or nodes that might complicate the data retrieval process.
