A company has a monolithic application that has become difficult to maintain because any small change requires redeploying the entire application. The team wants to improve maintainability without immediately moving to a full microservices architecture. They want to keep the application as a single deployable unit but improve code organization. Which approach best fits this goal?

Use a shared database and have multiple teams write to it

Decompose the monolith into microservices immediately

Refactor the monolith into a modular monolith with clear module boundaries

Add an API gateway in front of the monolith

In an event-driven architecture, what is the role of an event broker?

It stores and forwards events from producers to consumers.

It generates events based on business rules.

It provides a synchronous request-response communication channel.

It processes events and updates the database directly.

A company is evaluating whether to use SOA or microservices for a new application. They have a central integration team that can manage an ESB, but they also want to enable independent deployment of services. They are concerned about the governance overhead of SOA. Which statement best captures a key difference between SOA and microservices?

SOA requires a single database, while microservices require a separate database for each service

SOA is only used for legacy systems, while microservices are only used for new systems

SOA typically uses a centralized ESB for communication, while microservices often use lightweight APIs and decentralized governance

SOA is always synchronous, while microservices are always asynchronous
