What should a solutions architect do to meet these requirements?
Set up an Amazon ElastiCache for Memcached cluster to cache the scores for the web application to display.
Set up an Amazon ElastiCache for Redis cluster to compute and cache the scores for the web application to display.
Place an Amazon CloudFront distribution in front of the web application to cache the scoreboard in a section of the application.
Create a read replica on Amazon RDS for MySQL to run queries to compute the scoreboard and serve the read traffic to the web application.
Explanations:
Amazon ElastiCache for Memcached is primarily used for caching data without persistence. It does not support advanced data structures or persistent storage required to maintain scores during game sessions, making it unsuitable for real-time score tracking and restoration needs.
Amazon ElastiCache for Redis supports advanced data structures and offers persistence options, making it ideal for storing game scores that need to be quickly accessed and updated in near-real time. Redis can handle concurrent updates efficiently, which is critical for maintaining an accurate scoreboard during live gameplay and allowing for the preservation and restoration of scores.
Amazon CloudFront is a content delivery network (CDN) that is used to cache static content and accelerate web applications. While it can reduce latency for certain types of content, it is not designed for real-time data such as live scores, which require frequent updates. Thus, it would not meet the requirement for maintaining an up-to-date scoreboard.
While creating a read replica in Amazon RDS for MySQL can help distribute read traffic and reduce the load on the primary database, it does not address the requirement for near-real-time updates and the ability to preserve and restore game scores. Additionally, relying on a database query for a live scoreboard may introduce latency that is not suitable for a competitive gaming environment.
