Eventarc
Eventarc is a Google Cloud messaging service designed to help developers build event-driven architectures. It allows you to create these systems without needing to implement, customize, or maintain the underlying infrastructure yourself. This abstraction simplifies the process of connecting different cloud resources and services through events, reducing the operational burden on engineering teams who want to focus on application logic rather than infrastructure management.
You should choose Eventarc when you need a managed solution for event-driven patterns without the overhead of custom infrastructure maintenance. However, be aware that there is no free tier available for this service. You will be charged based on a pay-as-you-go pricing model, meaning every usage incurs costs from the start, which could impact budgets for projects expecting free usage allowances.
