AWS Certified Solutions Architect Associate SAA-C03 Practice Question
Your client wants to improve the response time and reliability of their cloud-hosted service for customers spread worldwide. The existing setup consists of a centralized cloud deployment with a growing demand for adherence to regional data protection regulations. Which strategy should you employ as the architect to fulfill these performance and legal requirements?
Opt for a tightly-clustered infrastructure in the original data center to maximize throughput and processing power for the service.
Consolidate resources into a single data center with an enhanced network connection to reduce service latency for all users regardless of their location.
Distribute resources across strategically located data centers and utilize DNS services featuring traffic routing based on the origin of requests to deliver optimal performance.
Expand the deployment within the current data center location and utilize on-premises hardware to handle regional demands.
To achieve high availability and low latency for a service catering to a global audience, it is important to have a geographical spread in the deployments. Using geographical routing mechanisms also contributes to serving your customers from the nearest data center, hence improving latency. In contrast, single-region approaches with multi-site deployments or on-premises extensions do not provide the necessary global coverage. Moreover, leveraging placement strategies restricted to compute resources does not address geolocation-based routing or regional compliance concerns.
