Event Driven Architecture Pattern

• This architecture comprises multiple decoupled micro services

• Events refer to a change in state or update

• Events trigger communication between services

• Events can carry the state or act as messengers as notifications

• Event Producers

• Event Routers

• Event Consumers

Event producer apps and consumer apps are decoupled, this enables the apps to independently deployed, update, scale.

• Independent scale and fail - no single point of failure
• As it is support decoupled architecture, apps/services can be built in varieties of tech stack in contrast with monolith arch

Fault-tolerant design patterns

• Understand the resiliency, scaling aspects to accommodate the demand
• Objective is to build resiliency into workloads
