Engineering Modern SAP Cloud Systems

Build SAP Cloud Systems That Work Beyond the Demo

Modern SAP development is no longer just about extending an ERP system. Enterprise applications increasingly span SAP S/4HANA Cloud, SAP Business Technology Platform, APIs, integration services, identity, automation, and cloud-native development. The difficult part is knowing how these pieces should fit together-and how to keep the resulting system reliable when it reaches production.

Engineering Modern SAP Cloud Systems provides a practical, architecture-focused guide to building modern SAP cloud solutions that are designed for real enterprise environments.

The book explores the decisions developers and architects face throughout the application lifecycle, from defining the right application boundary and selecting an appropriate runtime to managing data, integrating with SAP systems, securing applications, and delivering changes safely into production.

Inside, you will explore:

• Modern SAP cloud architecture - Understand where application responsibilities belong and how to establish boundaries between SAP systems and cloud applications.

• Application development on SAP BTP - Evaluate runtimes and development approaches based on the responsibility your application actually needs to own.

• Data architecture - Design application data without accidentally creating a second system of record.

• SAP integration - Work with APIs and integration patterns while avoiding tightly coupled chains of synchronous calls.

• Resilient integration - Apply asynchronous processing, messaging, retries, idempotency, and recovery patterns where distributed systems require them.

• Security and authorization - Design around identities, roles, permissions, tenants, technical users, and the identity behind each request.

• Production engineering - Identify the assumptions that appear harmless during development but fail under scale, concurrency, outages, restarts, and real operational conditions.

• Deployment and delivery - Build predictable paths from source control through testing and deployment to production, with configuration, observability, and recovery treated as part of the engineering process.

Rather than presenting SAP cloud technologies as isolated features, this book focuses on the engineering decisions that connect them. The goal is not simply to make an application run-it is to build systems that can be understood, secured, changed, operated, and recovered over time.

Engineering Modern SAP Cloud Systems is written for SAP developers, enterprise developers, cloud engineers, solution architects, and technical professionals who want a practical understanding of how modern SAP cloud applications are designed and operated in production.
