A logistics company runs a tracking application in a single region. Customers across the region report slow page loads, and the engineering team finds two contributing causes: the database is the slowest component in every request, and customers far from the region experience additional network delay. Two proposals are made. Proposal P adds an application-level cache between the application and the database. Proposal Q adds a second region with a read replica close to the distant customer base. The most appropriate next step is to:

Question

Accepted Answer

Implement Proposal P first, since application-level caching addresses the database bottleneck and is the lower-effort change to deploy and validate.

Answer

Implement Proposal Q first, since adding a region addresses both causes simultaneously by placing a read replica near the customers and reducing primary load.

Answer

Implement neither proposal, since the two causes interact in ways that make individual interventions ineffective for any application of this kind.

Answer

Implement both proposals at the same time, since each addresses a different cause and the combined effect must be evaluated together rather than separately.
