Zorluk: OrtaAWS Database Services

A developer is designing a real-time multiplayer game and needs a data store to manage a highly dynamic leaderboard. The application requires response times in the sub-millisecond range to maintain a fluid user experience. Which AWS service is best suited to meet these requirements?

  1. Amazon ElastiCacheCevap
  2. B
    Amazon DynamoDB
  3. C
    Amazon RDS
  4. D
    Amazon EC2 with a self-managed database

Cevap

Amazon ElastiCache is the best choice because it provides fully managed in-memory caching that delivers sub-millisecond response times required for gaming leaderboards.
Amazon ElastiCache is correct because it uses in-memory data structures (supporting Redis and Memcached) to serve read-heavy workloads with sub-millisecond response times, making it ideal for real-time leaderboards.

Adım Adım Çözüm

1
Analyze the application requirements.
Identify that the system needs to support a highly dynamic gaming leaderboard with sub-millisecond latency.
This establishes the performance threshold and workload type.
2
Compare AWS database and caching services against the requirements.
Determine that relational databases (like RDS) and standard NoSQL databases (like DynamoDB) operate in the millisecond range, while in-memory stores (like ElastiCache) operate in the sub-millisecond range.
Matching the latency requirement to the correct database class ensures the right architectural decision.
