When should you consider using the Microservices architectural pattern in an OutSystems application?

The Microservices architectural pattern is particularly beneficial when dealing with large and complex applications that require modularity and scalability. This approach allows development teams to break down monolithic applications into smaller, independently deployable services that can communicate with each other. Each microservice can be developed, deployed, and scaled individually, thus enhancing the overall agility of the development process. This means that teams can implement changes, add features, or fix issues without impacting the entire application, leading to reduced downtime and faster time-to-market.

In circumstances where applications are already too complex, utilizing microservices allows developers to manage different functionalities in isolation, promoting clear boundaries between services. This approach not only simplifies maintenance but also fosters optimized resource utilization, as specific services can be horizontally scaled according to demand.

The other choices do not adequately leverage the advantages of microservices. Small applications with limited functionality do not typically require the overhead and complexity that comes with implementing microservices. Similarly, simple CRUD operations do not benefit significantly from the microservices pattern, which is more suited to complex domains that require the ability to rapidly evolve and scale different parts of the application independently. Lastly, while having a small or inexperienced team can influence architectural decisions, the microservices approach generally requires a more sophisticated understanding of system design and
