Overview of ABAP in SAP Cloud Platform

SAP Cloud Platform is SAP’s strategic Platform as a Service (PaaS) offering for SAP customers and partners to build, integrate and extend SAP’s business solutions and services. Today, SAP Cloud Platform applications and extensions can be built with different development environments like Java or Node.js, but SAP’s own environment for business applications, ABAP, has not yet been available so far.

ABAP in SAP Cloud Platform is SAP’s new Platform as a Service (PaaS) offering for ABAP. Since many years, ABAP has been the foundation for SAP’s on-premise solutions. With ABAP in SAP Cloud Platform, ABAP developers can make use of their existing ABAP know-how to develop and run ABAP applications in the Cloud.
