The document discusses the limitations of monolithic architecture and the advantages of transitioning to microservice architecture, such as improved scalability, faster deployment, and clearer service boundaries. It highlights challenges in adopting microservices, including operational overhead and transaction management. The document also notes that while microservices offer benefits, they are not a one-size-fits-all solution.
