One of the following Tools allows you to manage the application's lifecycle across an infrastructure. Which one?

LifeTime is the tool designed specifically for managing the application lifecycle across an entire infrastructure. It provides comprehensive features for deploying, monitoring, and managing different environments within an OutSystems application. This includes version control, deployment management, and the ability to track the application's performance and usage metrics, along with the capability to coordinate the deployment of applications across development, testing, and production environments.

In contrast, Service Center is primarily focused on monitoring and managing the applications at a more granular level, like handling users, monitoring logs, and managing environments, but it does not provide the same lifecycle management capabilities that LifeTime offers. Service Studio is mainly a development environment where developers create and design applications, while Integration Studio is used for integrating external systems and defining data sources and structures for the applications. Thus, while all the other options play vital roles within the OutSystems ecosystem, LifeTime uniquely fulfills the need for coherent lifecycle management across multiple environments.
