A cloud administrator is monitoring a database system and notices an unusual increase in the read operations, which is causing a heavy load in the system. The system is using a relational database and is running in a VM.
Which of the following should the administrator do to resolve the issue with minimal architectural changes?
Correct Answer: b. Use a cache system to store reading operations
Using a cache system reduces the load on the database by storing frequently read data in a faster, in-memory store. This approach improves read performance without changing the database architecture significantly, making it an efficient solution for handling increased read operations with minimal disruption.
Why the other options are incorrect:
a. Migrate the relational database to a NoSQL database:
Migrating to NoSQL involves major architectural changes and data model redesign, which is complex and time-consuming, not minimal.
c. Create a secondary standby database instance:
A standby instance typically supports failover and high availability, not load balancing for read-heavy workloads, so it won’t reduce read load effectively.
d. Implement the database system using a DBaaS:
Switching to Database as a Service (DBaaS) involves significant migration and architectural changes rather than a minimal adjustment.
