AWS Eventbridge
Eventbridge enables imlementation of loose coupling.
- Services have little dependnece on each other.
- Changes to one component does not have a massive impact on the other.
- Provides greater flexability.
Eventbridge is serverless.
- Allows you to connect aws services and components with 3rd party systems.
- Events are pushed to an event bus.
- Rules trigger the forwarding of events to targets.
Event Driven Architecture
The sysem responds asynconiosly.
In an event driven system there are three main components:
- Producers - generate events.
- ⬇️
- Event bus - communcation channel
- ⬇️
- Consumers - resond to events.
Why EDA
- Scaleable
- Flexible
- Responsive
- Resilient
Event Buses
The event bus is a pipeline that recives messages.
- The default event bus is the one that recives messages from AWS services.
- Custom event buses can be created - these can recive messages from AWS accounts other than the one of the event bus.
- Partner event busses can send / recive messages from SaaS partners.
- Up to 300 rules can be on an event bus.
- If you need more than 300 rules then add a custom event bus.
Events on a scedule
- Tasks can be run on a scedule in event bridge.
- This can be used to do things such as send weekly reminders.
