@crichardson
What’s an event?
@crichardson

@crichardson
Examples of events
@crichardson
Events play a role at every level of
an architecture
@crichardson
Events on the outside E-commerce
Application
Fulfilment
Application
@crichardson
An application emits an event when…
OrderCreated
E-commerce

OrderShipped InvoiceBecameOverdue
State changes Passage of time
@crichardson
Who consumes an event?
Notification
Service
Dashboard/
Monitoring
OrderCreated
Email

How to transport events?

Inside the firewall: Messaging-based IPC

Outside the firewall
@crichardson
Polling for events
HTTP
Periodically poll for events
Atom Publishing Protocol (AtomPub)
Based on HTTP
Head is constantly changing
Tail is immutable and can be efficiently cached
High-latency, inefficient

Webhooks = web friendly publish/

The Microservice architecture

large, complex applications
@crichardson
E-commerce application - refactored to

But what about
transactions and
queries that span
services?
Private DBs
@crichardson
How to implement transactions that
span services?
@crichardson
How to enforce the customer’s credit
limit?
Customer

total
Invariant: sum(open order.total) <= customer.creditLimit

@crichardson
Use event-driven, choreography-based
sagas
Customer

creditReservations
...
Order

placeOrder()
Order Service Customer Service
create()
Order created
Credit Reserved
reserveCredit()
approve()
@crichardson
How to implement queries that
span services?
@crichardson
Find new customers who have
placed high value orders that have
shipped
@crichardson
Use Command Query Responsibility
Segregation
Order
Service
Customer

Message Broker

@crichardson

DDD: Aggregates publish domain events
Order
OrderLine

Aggregate

Domain event
Publishes

@crichardson
Business logic explicitly invoking event
publishing API
≪service≫
OrderService
≪aggregate≫
Order
DomainEvent
Publisher
placeOrder(…)

≪event≫
OrderCreated
publish(…)

• Simple
• Easy to adapt existing code
But
• Events are not automatic
• Tricky to publish messages transactionally
publish(…)
@crichardson
Use event sourcing
Event table

Reliable publishing, aggregate history, auditing, …. YET radically different
