Enterprise Integration Patterns
A foundational to advanced learning path for SAP architects covering enterprise integration patterns across ECC, S/4HANA (on-premise, private and public cloud) and BTP hybrid landscapes. Covers pattern selection, synchronous vs asynchronous design, event-driven architecture, API management, clean core integration strategy, NFRs, security, governance and migration/rollback considerations for integration decisions.
Overview
A foundational to advanced learning path for SAP architects covering enterprise integration patterns across ECC, S/4HANA (on-premise, private and public cloud) and BTP hybrid landscapes. Covers pattern selection, synchronous vs asynchronous design, event-driven architecture, API management, clean core integration strategy, NFRs, security, governance and migration/rollback considerations for integration decisions.
Lessons in this topic
- SAP Enterprise Integration Patterns Tutorial (Part 1)Introduces the core integration pattern categories relevant to SAP landscapes and why choosing the right pattern early prevents costly rework later.
- Selecting Integration Patterns: Synchronous, Asynchronous and Hybrid Trade-offs (Part 2)Explains how to evaluate and select between synchronous, asynchronous and hybrid integration patterns based on concrete non-functional requirements and SAP deployment constraints.
- Synchronous vs Asynchronous Integration: Choosing the Right Communication Style (Part 3)Explains when to use synchronous request-response versus asynchronous message-based integration between SAP and non-SAP systems, and the architectural consequences of each choice.
- Governance, Cost Control, and Roadmap Evolution for Enterprise Integration Landscapes (Part 4)Learn how to govern a growing enterprise integration landscape, control recurring integration cost drivers, and plan a multi-year roadmap that keeps pace with S/4HANA and BTP evolution without accumulating technical or contractual debt.
- Event-Driven Architecture: Choreography, Orchestration, and Idempotency in Hybrid SAP Landscapes (Part 5)Analyzes advanced event-driven integration design choices — choreography versus orchestration — along with idempotency, ordering, and governance concerns when SAP and BTP-based event producers and consumers interact.
Interview questions covered
- What are the core concepts of Enterprise Integration Patterns, and how would you explain them clearly in an SAP interview?
- How would you apply Enterprise Integration Patterns in a real SAP project? Walk through the design or implementation approach.
- A production issue is reported in Enterprise Integration Patterns. What would you check first, and how would you troubleshoot it systematically?
- What are the most important design decisions, trade-offs, and best practices in Enterprise Integration Patterns?
- Suppose you inherit an existing Enterprise Integration Patterns solution. How would you review it before making a change?
- Using this SAP project situation — An architect was brought into a program eighteen months after go-live because the client's monthly integration platform bill had tripled and nobody could explain why — explain Governance, Cost Control, and Roadmap Evolution for Enterprise Integration Landscapes. What should happen, which concepts or process steps matter, and what common mistake would you avoid?
- A project encounters this situation while working on Selecting Integration Patterns: Synchronous, Asynchronous and Hybrid Trade-offs: A manufacturing client needed to integrate their S/4HANA Private Cloud system with a third-party quality management tool. Walk through how you would analyze the requirement or issue, what you would validate, and how you would test the solution before release.
- A project encounters this situation while working on Synchronous vs Asynchronous Integration: Choosing the Right Communication Style: An architect was asked why order confirmations to a 3PL logistics provider were causing intermittent order-entry delays. Walk through how you would analyze the requirement or issue, what you would validate, and how you would test the solution before release.
- You are the senior consultant/architect responsible for Event-Driven Architecture: Choreography, Orchestration, and Idempotency in Hybrid SAP Landscapes. The project situation is: A program integrating S/4HANA order creation with a BTP-based fulfillment microservice and a third-party carrier platform initially used pure choreography. How would you assess the design, identify the highest-risk failure modes, and define the evidence required before approving it for production?
- Using this SAP project situation — During a project scoping workshop for a retail company running ECC with plans to move to S/4HANA Private Cloud, the integration team initially proposed direct RFC connections from ECC to five new e-commerce microservices — explain Foundations of Enterprise Integration Patterns in SAP Landscapes. What should happen, which concepts or process steps matter, and what common mistake would you avoid?
