Draw the Architecture of a Scalable, Fault$-$Tolerant Distributed SystemYour task is to draw a diagram representing the architecture of a scalable, fault$-$tolerant distributed system that can handle web traffic for a high$-$demand online service. Your drawing should include the following components and their interactions:$1.$Client Layer: Show how users $($clients$)$ connect to the system, including any load balancers that distribute requests to prevent overload on any single server$\mathrm{.}2.$Service Layer: Illustrate a set of stateless service nodes that handle client requests. Include how these services communicate with each other and with the data layer$\mathrm{.}3.$Data Layer: Depict how data is stored, replicated, and retrieved across multiple database servers to ensure fault tolerance and high availability. Indicate any database clusters, replication strategies, and partitioning mechanisms$\mathrm{.}4.$Cache Layer: Include a caching mechanism to reduce the load on the database layer by storing and serving frequent requests$\mathrm{.}5.$Failover Mechanisms: Illustrate how the system detects and handles failures at different layers, ensuring continuous operation even when individual components fail.Your drawing should clearly indicate the flow of data through the system, from the client making a request to the response being served. Use symbols or labels to represent different components $($like servers, databases, caches$)$ and arrows to show the direction of data flow and interactions between components.
