Event-Driven Architecture (EDA) has been widely adopted for companies looking to accelerate their digital transformation. These companies realized that batch-based, point-to-point Integrations slow down the business and leave a technical debt. EDA improves the ability to react to changes in real-time and improves the overall customer experience. API-led connectivity approach unlocks data through APIs allowing companies to create a composable business. In this session, I will share how to integrate Salesforce with multiple ERPs by combining EDA & API-led Connectivity through MuleSoft.

● Expose data and business
capabilities for reuse
● Productized and designed for
ease of consumption
● Easily managed for Security,
Scalability and Performance
● Discoverable and accessible
through self-service API Portals
APIs as standard building blocks

Application Network
● Emerges bottom-up
● Self-Service
● Provides visibility, security, and
governability at every API Node
● Is recomposable: It bends, not breaks
● Built for change

● Events represents Facts of Information
● Facts already happened
● Facts are immutable
● You can listen the facts if you want to
What is an Event?

15. #CD22
Event Types
• Intent
• Direct to a Single Address
• Expect an action to be taken for
someone
• Side-effects
• Imperative-Tense
CreateOrder, ShipProduct
Commands
• No Intent
• Broadcast communication
• No expectation
• Depends on the consumer
• Past-Tense
OrderCreated, ProductShipped

Modeling Events
“When you start modeling Events, it forces you to think about the
behavior of the system. As opposed to thinking about the
structure of the system.”
Greg Young

17. #CD22
● Overall Integration Strategy
● Support for legacy systems
● Structural changes to messages
● Lack of visibility between publishers and subscribers
● Performance bottlenecks
Challenges to consider when implementing EDA

18. #CD22
● Real-time notifications
● Paralell processing
● High-volume reads
● Sending the same data to different systems
● Frequently introducing new systems or devices into an IT landscape
● IoT devices
● Mobile devices and systems that may be offline when changes occur

Platform Events

22. #CD22
• Special type of Platform Events
• Published automatically by Salesforce in real-time when records change
• Events published for: create, update, delete, and un-delete operations
• Events are stored up to 3 days
• Asynchronous Triggers can be implemented, only after insert
(Events are immutable)

• Retail Execution Mobile App connected to Salesforce
• Salesforce Single Org with the Backend of the Mobile App
• Application rolled-out to more than 20 affiliates
• Each affiliates manage their own ERP (JDE, NAV, SAP)
• Account Integration is required in almost real time
Scenario - Integrating Salesforce with 3 ERPs

27. #CD22
• Invoke every ERP with outbound calls from APEX
• We have to code all transformations from Objects to APIs
by country (different formats: SOAP, JSON, v1, v2, etc.)
• Error Handling, Retries, Security, and so on.
• Point-to-point Integration
• APEX is not a Middleware! --> Technical Debt

28. #CD22
Principles
• Keep Salesforce “clean” with no ERP dependency
• The Integration is completely transparent for Salesforce
Opportunity to
• Introduce a Middleware (e.g. MuleSoft)
• Design an “Event-Driven” solution combining API-led connectivity

33. #CD22
• Event-Driven Architecture is a good option for decoupling applications
(producers and consumers)
• Salesforce offers out of the box powerful capabilities like CDC
• Platform Events can be defined for more flexibility (payload, publishing)
• API-led connectivity provides an approach for creating Application
Networks promoting reusability
• EDA & API-led connectivity can complement each other for building
robust Integration Architectures
