End-to-End SAP S/4HANA Rise Migration to SAP Cloud: Architecting a Secure and Scalable Landscape with Cloud Connector, Landscape Migration Server, SLT Server, Cloud Integration, and Governance Framework

Abstract

Companies are moving away from the old SAP ECC into SAP S/4HANA on clouds to enjoy the agility, scaling ability, and innovation that come with cloud platforms. The RISE with SAP package further hastens this development by packaging the infrastructure, tools and managed services. Nevertheless, there are design and operational issues associated with an end-to-end migration, which must be secured, data replication in real-time, good integration, and powerful governance. The paper suggests an overall architecture of an end-to-end SAP S/4HANA RISE migrations, including Cloud connector, Landscape Migration Server (LMS), SAP Landscape transformation (SLT) server and SAP Cloud integration (CPI) under the coordination of a holistic governing framework. It is designed such that security is by design, that it is scalable and resilient and that it has modular layers and separation of concerns. We define component level roles, data flows, security controls and governance structures and test the architecture to various evaluation parameters like latency, throughput, fault tolerance and compliance. The outcome is a blueprint and best-practice guide of organizations looking to move SAP landscapes safely and in size to the cloud.
