Microservices in SAP HANA XSA
Build enterprise-grade microservices in the SAP HANA Advanced Model (XSA). This book explains building scalable APIs in XSA and the benefits of building microservices with SAP HANA XSA. This book covers the cloud foundry (CF) architecture and how SAP HANA XSA follows the model. It begins with the details of the different architectural layers of applications hosted in XSA (specifically, microservices). Everything you need to know is presented, including analyzing requests, modularization, database ingestion, building JSON responses, and scaling your microservices. You will learn to use developmental tools such as the SAP WEB IDE, POSTMAN, and the SAP HANA Cockpit for XSA, including debugging examples on SAP HANA XSA with code snippets showing how microservices can be developed, debugged, scaled, and deployed on SAP HANA XSA. Microservices are divided into security and authentication, request handling, modularization of Node.js, and interaction with the SAP HANA database containers and response formatting. An end-to-end scenario is presented of a Node.js REST API that uses HTTP methods, concluding with deploying an SAP HANA XSA project to a production environment. This book is simple enough to help you implement a Node.js module in order to understand the development of microservices, and complex enough for architects to design their next business-ready solution integrating UAA security, application modularization, and an end-to-end REST API on SAP HANA XSA. What You Will Learn Know the definition and architecture of cloud foundry and its application on SAP HANA XSA Understand REST principles and different HTTP methods Explore microservices (Node.js) development Database interaction from Node (executing SQL statements and stored procedures) Who This Book Is For Architects designing business-ready solutions that integrate UAA security, application modularization, and an end-to-end REST API on SAP HANA XSA
SAP HANA Architecture and Implementation
"SAP HANA Architecture and Implementation" Designed for technology professionals, architects, and enterprise strategists, "SAP HANA Architecture and Implementation" offers an authoritative guide to mastering the SAP HANA platform. Beginning with the evolution and adoption of SAP HANA, the book meticulously explores the underlying principles—such as in-memory computing, columnar storage, and massive parallelism—that set SAP HANA apart from traditional database architectures. Readers will gain a comprehensive understanding of how SAP HANA converges transactional and analytical processing, integrates seamlessly into the broader enterprise landscape, and supports today’s most demanding workloads. Delving deep into system architecture, the book examines critical SAP HANA components, including system and node topologies, internal server mechanisms, persistence and memory management, and advanced resource governance. Coverage extends into high-availability and disaster recovery architectures, optimized data distribution, and efficient workload management. Subsequent chapters provide hands-on, best-practice guidance for data modeling, advanced SQLScript programming, and leveraging HANA’s native support for complex analytical scenarios encompassing graph, spatial, and text data. Security and governance receive thorough treatment, with expert insights on authentication, authorization, encryption, auditing, and the operational hardening required for enterprise compliance. Beyond deployment models—on-premises, cloud, and hybrid—the book offers a complete perspective on data integration, life cycle management, and extensibility through native application development, REST APIs, and alignment with SAP’s Business Technology Platform. Readers are equipped with cutting-edge approaches to monitoring, scaling, troubleshooting, and performance tuning. The concluding sections give an in-depth view into large-scale implementations, emerging trends like AI and data mesh, and concrete pathways for professional growth and certification, making this book an indispensable resource for anyone seeking to lead successful SAP HANA initiatives.
