SAP Cloud Application Programming Model

Welcome to the SAP Cloud Application Programming Model (aka ‘CAP’ with silent ‘M’). This blog introduces the key concepts and design principles of CAP, complemented with best practices and a features overview.

The Cloud Application Programming Model is an open and opinionated framework of languages, libraries and tools for building enterprise-grade services and applications.

The CAP framework features a mix of broadly adopted open-source and SAP technologies. The major building blocks are highlighted in the figure below.

Service SDK’s: CAP have libraries available for both Java and Node.js which used to provide and consume services through synchronous and asynchronous API’s. SDK’s also have integration to services such as authentication and credential-flows and on/off boarding of SaaS tenants.

This is great intro to this interesting topic. This reminds me of the erstwhile RDL that was created for HANA DB. By the way, could you suggest what kind of proejcts will benefit most using CAP?
