A financial services company is planning to migrate its core trading platform to Google Cloud. This platform requires extremely low latency (sub-millisecond) for transaction processing and strict data residency controls due to regulatory requirements. The current on-premises setup uses specialized hardware and direct fiber connections. Which Google Cloud design principle should be prioritized to meet these stringent requirements?
- ADesign for multi-region active-active deployment to maximize global availability.
- BImplement a data lake solution on Cloud Storage for all historical trading data.
- CUtilize dedicated interconnects and carefully select regions/zones for compute and storage placement.
- DLeverage fully managed serverless services for all components to reduce operational overhead.
Show answer & explanationAnswer & explanation
Correct answer: C. Utilize dedicated interconnects and carefully select regions/zones for compute and storage placement.
For extremely low latency and strict data residency, utilizing dedicated interconnects like Cloud Interconnect provides direct, high-bandwidth, low-latency connectivity to Google Cloud, bypassing the public internet. Careful selection of regions and zones ensures data residency and minimizes network hops for compute and storage, directly addressing the sub-millisecond latency and regulatory requirements.
Why the other options are wrong
- A. Multi-region deployments increase latency due to geographical distance, which conflicts with sub-millisecond requirements, though it improves global availability.
- B. A data lake on Cloud Storage is suitable for analytics but doesn't directly address the low-latency transaction processing needs of the core trading platform or network connectivity requirements.
- D. Serverless services often introduce some latency overhead, which might not meet sub-millisecond requirements for a core trading platform.
Cloud Interconnect
Google Cloud Interconnect provides high-bandwidth, low-latency connections between an on-premises network and Google Cloud, bypassing the public internet.
- Offers Dedicated Interconnect or Partner Interconnect.
- Crucial for hybrid cloud architectures requiring high throughput and low latency.
- Supports private IP space communication between networks.
Memory trick: Connect directly, place precisely, for speed and secrecy.
