A company developed a new multiplayer video game as a web application in a three-tier architecture in a VPC with Amazon RDS for MySQL in the database layer. Several players will compete concurrently online. Developers want a near-real-time top-10 scoreboard and the ability to stop and restore the game while preserving current scores. What should a solutions architect implement to meet these requirements?

Amazon ElastiCache for Redis is the best choice because it supports complex data structures like sorted sets, which are ideal for maintaining a real-time top-10 scoreboard. Redis can efficiently compute and store these scores, and its persistence options allow for stopping and restoring the game while preserving scores. ElastiCache for Memcached is a simpler key-value store and lacks the advanced data structures and persistence needed for this use case. Amazon CloudFront is a content delivery network (CDN) and is not suitable for dynamic, real-time data caching within an application. A read replica on Amazon RDS for MySQL would offload read traffic but would not provide the near-real-time performance or efficient data structures for a dynamic scoreboard that Redis offers.
