An e-commerce application experiences slow response times during flash sales. The product catalog is read frequently but changes rarely. The team wants to reduce database load and improve response times without changing the database schema. Which design pattern is most appropriate?

Use a queue to process catalog reads asynchronously.

Make the application stateless by removing all local variables.

Add a caching layer between the application and the database for catalog data.

Scale the database vertically by adding more CPU and memory.

A team is evaluating two designs for a new service. Design A is a monolith that is simple to deploy but hard to scale. Design B is a set of microservices that scale well but are complex to deploy and operate. The team has a small DevOps team and needs to launch quickly. What is the most pragmatic decision?

Choose Design B because it is more scalable, regardless of the team's capacity.

Choose Design A and never refactor, accepting the scaling limits.

Start with the monolith (Design A) and plan to refactor to microservices (Design B) when scaling becomes a real bottleneck.

Choose Design B but hire a larger DevOps team to manage it.
