SAP on the Cloud (Management for Professionals)

This book offers a comprehensive guide to implementing SAP and HANA on private, public and hybrid clouds. Cloud computing has transformed the way organizations run their IT infrastructures: the shift from legacy monolithic mainframes and UNIX platforms to cloud based infrastructures offering ubiquitous access to critical information, elastic provisioning and drastic cost savings has made cloud an essential part of every organizationℓ́ℓs business strategy. Cloud based services have evolved from simple file sharing, email and messaging utilities in the past, to the current situation, where their improved technical capabilities and SLAs make running mission-critical applications such as SAP possible. However, IT professionals must take due care when deploying SAP in a public, private, or hybrid cloud environment. As a foundation for core business operations, SAP cloud deployments must satisfy stringent requirements concerning their performance, scale and security, while delivering measurable improvements in IT efficiency and cost savings. The 2nd edition of ℓ́ℓSAP on the Cloudℓ́ℓ continues the work of its successful predecessor released in 2013, providing updated guidance for deploying SAP in public, private and hybrid clouds. To do so, it discusses the technical requirements and considerations necessary for IT professionals to successfully implement SAP software in a cloud environment, including best-practice architectures for IaaS, PaaS, and SaaS deployments. The section on SAPℓ́ℓs in-memory database HANA has been significantly extended to cover Suite on HANA (SoH) and the different incarnations of HANA Enterprise Cloud (HEC) and Tailored Datacenter Integration (TDI). As cyber threats are a significant concern, it also explores appropriate security models for defending SAP cloud deployments against modern and sophisticated attacks. The reader will gain the insights needed to understand the respective benefits and drawbacks of various deployment models, and how SAP on the cloud can be used to deliver IT efficiency and cost-savings in a secure and agile manner This book offers a comprehensive guide to implementing SAP and HANA on private, public and hybrid clouds.

It describes and discusses the latest developments and challenges and suitable solutions, and also outlines future trends where possible. To ensure that this book is also useful to readers who do not consider themselves experts in this area, this book explains in detail the backgrounds of the various solutions. Also, practice-oriented case studies are provided throughout the book in order to make the reader aware of essential but perhaps less obvious points. However, the book concentrates exclusively on the set up and operation of the SAP infrastructure. It does not give details on how to install and customize the SAP software, nor does it deal with the much more complex tasks involved in business process implementation and reengineering.​ Front Matter....Pages i-xix Clouds Demystified....Pages 1-17 From R/3 to S/4HANA....Pages 19-48 Service Levels for SAP on Cloud....Pages 49-74 Securing SAP on the Cloud....Pages 75-120 Change and Configuration Management....Pages 121-138 SAP and the Internet of Things....Pages 139-151 The Hybrid Cloud....Pages 153-164 SAP Solutions on Public Clouds....Pages 165-183 Private Cloud Infrastructures for SAP....Pages 185-213 Stateless Computing....Pages 215-231 Economic and Legal Aspects of Cloud Computing....Pages 233-253 Back Matter....Pages 255-265
