Question 1 of 30
When orchestrating the migration of a high-frequency trading platform from a dedicated on-premise data center to a hybrid cloud architecture, Elara, the lead network architect, must navigate intricate dependencies and stringent uptime requirements. The platform relies on extremely low-latency inter-component communication and real-time data synchronization. What strategic approach best balances the need for seamless transition, robust performance, and adherence to financial regulatory compliance standards such as MiFID II\'s data integrity and audit trail mandates?
Implement a phased migration utilizing a hybrid connectivity model, establishing dedicated, low-latency private circuits between on-premise and cloud resources, coupled with extensive pre-migration performance benchmarking and parallel run testing to validate application behavior and data consistency before a controlled cutover.
Execute a full lift-and-shift migration of the entire trading infrastructure to the cloud, relying on standard internet VPNs for connectivity and assuming the cloud provider's inherent scalability will automatically address latency and synchronization issues.
Prioritize cost optimization by migrating only non-critical components to the cloud initially, leaving the core trading engine on-premise indefinitely and deferring any significant architectural changes to minimize immediate disruption.
Focus solely on re-architecting the application for a cloud-native environment before any migration begins, accepting a prolonged period of downtime to ensure a complete overhaul, and then performing a single, large-scale deployment.
