SAP System Architecture
Foundational and intermediate coverage of SAP System Architecture: the three-tier model, instance and work process design, system landscape layout, and how these architectural choices drive administration, monitoring, transport strategy, and high-availability planning across ECC, S/4HANA, HANA, and Cloud ALM environments.
Overview
Foundational and intermediate coverage of SAP System Architecture: the three-tier model, instance and work process design, system landscape layout, and how these architectural choices drive administration, monitoring, transport strategy, and high-availability planning across ECC, S/4HANA, HANA, and Cloud ALM environments.
Lessons in this topic
- System Landscape Design, Instance Distribution, and High Availability PlanningExplains how individual SAP systems are combined into a landscape (DEV/QAS/PRD), how instances are distributed across hosts for scalability, and the architectural patterns used to achieve high availability and disaster recovery.
- SAP ABAP Application Server Runtime: Dispatcher, Work Processes, and Memory AreasExplains how the SAP ABAP application server processes user requests internally through the dispatcher, work process types, and memory management, and how Basis consultants use this model to diagnose performance and availability issues.
- SAP Three-Tier Architecture and Core Building BlocksIntroduces the classic SAP three-tier architecture (presentation, application, database) and the core instance components a Basis consultant must understand before touching any production system.
