Build enterprise-grade microservices in 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 containersand 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.

You will:

• 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)
