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 organization s 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 SAP on the Cloud 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 SAP s 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."

本書提供了一個全面的指南，教導如何在私有、公有和混合雲上實施SAP和HANA。雲計算已經改變了組織運營IT基礎設施的方式：從過去的遺留的大型主機和UNIX平台轉向基於雲的基礎設施，提供對關鍵信息的無處不在的訪問、彈性供應和大幅節省成本，使雲成為每個組織業務策略的重要組成部分。過去，雲服務僅僅是簡單的文件共享、電子郵件和消息工具，但現在它們的技術能力和服務水平協議的改進使得運行像SAP這樣的關鍵應用程序成為可能。然而，IT專業人員在公有、私有或混合雲環境中部署SAP時必須謹慎。作為核心業務運營的基礎，SAP雲部署必須滿足對性能、規模和安全性的嚴格要求，同時提供可衡量的IT效率和成本節省的改進。《SAP on the Cloud》第二版延續了2013年成功發行的前作，提供了在公有、私有和混合雲中部署SAP的最新指南。為此，它討論了IT專業人員在雲環境中成功實施SAP軟件所需的技術要求和考慮因素，包括IaaS、PaaS和SaaS部署的最佳實踐架構。關於SAP的內存數據庫HANA的部分已經顯著擴展，涵蓋了HANA上的套件（SoH）以及HANA企業雲（HEC）和定制數據中心集成（TDI）的不同形式。由於網絡威脅是一個重要的關注點，本書還探討了適合保護SAP雲部署免受現代和複雜攻擊的安全模型。讀者將獲得所需的見解，了解各種部署模型的相應優點和缺點，以及如何以安全靈活的方式使用SAP雲來提供IT效率和成本節省。
