How do you know when to use event-driven architectures?

Event-driven architectures are used in distributed systems to decouple services and enable component-level scaling and iteration. Certain areas of any application experience more traffic than others, and a decoupled system allows for independent growth and isolation. This not only lowers blast radius in failure scenarios, but also allows for vertical scaling when necessary.

Momento provides a set of powerful services that enable event-driven architectures by loosely coupling services with Topics, storing events in Cache, and triggering stateless compute with webhooks.
