Integration Architecture
Foundational and intermediate concepts of SAP Integration Architecture: why integration strategy matters for enterprise landscapes, core integration patterns and styles, technology options across ECC, S/4HANA and BTP, and the trade-offs architects must evaluate when deciding how systems exchange data reliably, securely and at scale.

Foundational and intermediate concepts of SAP Integration Architecture: why integration strategy matters for enterprise landscapes, core integration patterns and styles, technology options across ECC, S/4HANA and BTP, and the trade-offs architects must evaluate when deciding how systems exchange data reliably, securely and at scale.
Lessons in this topic
- SAP Integration Architecture Tutorial (Part 1)Introduces the business and technical reasons integration architecture is a distinct architect-level discipline, covering common integration scenarios and the cost of getting it wrong.
- Comparing Integration Technology Options and Trade-offs (Part 2)Compares major SAP integration technology options (point-to-point, SAP Process Orchestration, SAP Integration Suite on BTP, direct OData/API calls) and the trade-offs architects must weigh for each.
- Choosing Integration Patterns: Point-to-Point, Middleware and API-Led Approaches (Part 3)Compares core integration patterns available to SAP architects and the trade-offs between direct connections, middleware-brokered flows and API-led design across ECC and S/4HANA landscapes.
- Integration Architecture Operating Model: Monitoring, Cost Governance, and Roadmap Evolution (Part 4)Establishes how an enterprise sustains a hybrid SAP integration landscape long-term through operating model design, monitoring and alerting strategy, cost governance across integration platforms, and a phased roadmap for evolving toward clean-core-aligned integration.
- Designing Hybrid Integration Architecture for Clean Core S/4HANA Landscapes (Part 5)Explains how to design a hybrid integration architecture that combines synchronous and event-driven integration on BTP while keeping the S/4HANA core clean, addressing NFRs, security, and governance.
Interview questions covered
- What are the core concepts of Integration Architecture, and how would you explain them clearly in an SAP interview?
- How would you apply Integration Architecture in a real SAP project? Walk through the design or implementation approach.
- A production issue is reported in Integration Architecture. 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 Integration Architecture?
- Suppose you inherit an existing Integration Architecture solution. How would you review it before making a change?
- Using this SAP project situation — During an S/4HANA transformation program, the retail client had over 40 point-to-point interfaces between ECC, a legacy warehouse system, and a third-party e-commerce platform, built over eight years by different teams — explain Why Integration Architecture Matters in SAP Landscapes. What should happen, which concepts or process steps matter, and what common mistake would you avoid?
- Using this SAP project situation — Two years after a large manufacturer's S/4HANA public cloud rollout, an architecture health check found 40 percent of interfaces were undocumented direct API calls added by individual teams to meet urgent deadlines, several duplicating functionality already available through the central Integration Suite tenant, and monthly API consumption costs had tripled without a corresponding increase in business volume — explain Integration Architecture Operating Model: Monitoring, Cost Governance, and Roadmap Evolution. What should happen, which concepts or process steps matter, and what common mistake would you avoid?
- A project encounters this situation while working on Comparing Integration Technology Options and Trade-offs: A manufacturing client running S/4HANA private cloud needed to integrate with a third-party transportation management system. 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 Choosing Integration Patterns: Point-to-Point, Middleware and API-Led Approaches: A retail company migrating from ECC to S/4HANA private cloud inherited over forty point-to-point RFC interfaces built over a decade. 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 Designing Hybrid Integration Architecture for Clean Core S/4HANA Landscapes. The project situation is: A manufacturing company building a private cloud S/4HANA landscape with side-by-side extensions on BTP needed to replicate material master changes to a legacy warehouse management system and simultaneously notify a customer portal of stock changes in near real time. How would you assess the design, identify the highest-risk failure modes, and define the evidence required before approving it for production?
