Which resource is primarily affected by an increase in read requests in a cloud database?

1. CPU

2. RAM

3. Networking

4. Storage

The correct answer is: Storage

An increase in read requests in a cloud database primarily impacts the storage resource. When users make read requests, the database needs to retrieve data from its storage system. This involves accessing, reading, and sending the data back to the user, which puts strain on the storage capabilities. In a typical cloud environment, the storage system may involve various configurations, such as solid-state drives (SSDs) or traditional hard drives, and the performance of these storage resources can affect how quickly read requests are fulfilled. High read activity can lead to increased latency if the storage system becomes a bottleneck, requiring fast and efficient access to data. While CPU and RAM may also be involved, they play different roles. CPU handles processing tasks including query execution, and RAM is used for caching data to speed up retrieval. However, the primary factor that directly reacts to increased read requests is the storage mechanism since that is where the data resides and must be accessed.
