Über dieses Buch

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.

1. Clouds Demystified

Abstract
Today, the cloud enables everything—or is everything just labeled “cloud”?
Michael Missbach, Thorsten Staerk, Cameron Gardiner, Joshua McCloud, Robert Madl, Mark Tempes, George Anderson

2. From R/3 to S/4HANA

Abstract
SAP pre-defined business processes are provided by the SAP Business Suite, NetWeaver, and appliances like HANA. But even for experts it is difficult to cope with the somewhat overwhelming number of components based on different technologies that pose different demands and restrictions to be considered when building a cloud infrastructure.
Michael Missbach, Thorsten Staerk, Cameron Gardiner, Joshua McCloud, Robert Madl, Mark Tempes, George Anderson

3. Service Levels for SAP on Cloud

Abstract
“The electricity has to be of good quality”—in the early days of electrification when customers didn’t have experience with this new technology the city council of a German village wrote this sentence in the contract with a utility company. This is quite similar to the definitions in many service level agreements for SAP solutions on public and private clouds.
Michael Missbach, Thorsten Staerk, Cameron Gardiner, Joshua McCloud, Robert Madl, Mark Tempes, George Anderson

4. Securing SAP on the Cloud

Abstract
Security must be implemented using a defense-in-depth strategy that spans across internal controls and segregation of duties, points of user access, network infrastructure, cloud data centers, and all the way up the application stack. Simply implementing firewalls between access boundaries is no longer sufficient. Modern cyber threats often target end user devices through spear phishing and malware campaigns designed to hijack user access to SAP resources and thus completely skirt traditional perimeter controls. Only comprehensive architecture based on threat-focused, continuous security capabilities can adequately defend SAP applications against modern cyber threats.

5. Change and Configuration Management

Abstract
The old advice “never touch a running system” can’t be followed anymore in cloud environments built with the intention to enable fast change. Practical experience shows that insufficiently prepared changes are the main cause of malfunction. Therefore, change management has particular significance as a central quality assurance instrument in the context of cloud management.
Michael Missbach, Thorsten Staerk, Cameron Gardiner, Joshua McCloud, Robert Madl, Mark Tempes, George Anderson

6. SAP and the Internet of Things

Abstract
The Internet of Things (IoT) was originally a theoretical concept for increasing the potential of automating systems by creating computer data representing the location and status of objects in the physical world. The concept has evolved to include real-time monitoring of people and things to allow for dynamic interaction intended to improve efficiency, productivity, and quality of life. According to Gartner Group, the Internet of things is the network of physical objects that contains embedded technology to communicate, sense or interact with the objects’ internal state or the external environment (Fig. 6.1).
Michael Missbach, Thorsten Staerk, Cameron Gardiner, Joshua McCloud, Robert Madl, Mark Tempes, George Anderson

7. The Hybrid Cloud

Abstract
Major platform revolutions always happened by introducing complete new technologies like the client/server model or the web and then introducing standards like the IP-protocol or hypertext that facilitated the usage and adoption of those new technologies. Just like the IP standard and routing technology enabled growth for the web, hybrid cloud standards nowadays start enabling a world of many clouds. The key capability is easy workload movement between different clouds without breaching SLAs.
Michael Missbach, Thorsten Staerk, Cameron Gardiner, Joshua McCloud, Robert Madl, Mark Tempes, George Anderson

8. SAP Solutions on Public Clouds

Abstract
There is no doubt that particularly public clouds will become an integral part of our lives in the next decade. We don’t have to look far for whether we use applications such as office-like-apps or services which are closer to the infrastructure such as storage on demand for our personal data.
Michael Missbach, Thorsten Staerk, Cameron Gardiner, Joshua McCloud, Robert Madl, Mark Tempes, George Anderson

9. Private Cloud Infrastructures for SAP

Abstract
As described in Chap. 1, a private cloud is the deployment of cloud computing principles and capabilities on your own premises and infrastructure. This can be compared to the idea of using utility services built on your own power plant. Just as a utility consumer doesn’t care about the technology of the boilers, turbines, and generators necessary to produce electrical power, a private cloud consumer doesn’t need to care about the servers, network, and storage necessary to generate the computing power that runs the applications services they consume. Nonetheless, you should have a good understanding of the underlying technologies whether you build and operate a private power plant or a private cloud datacenter.
Michael Missbach, Thorsten Staerk, Cameron Gardiner, Joshua McCloud, Robert Madl, Mark Tempes, George Anderson

10. Stateless Computing

Abstract
In a traditional deployment model the identity of a server depends on its hardware.
Michael Missbach, Thorsten Staerk, Cameron Gardiner, Joshua McCloud, Robert Madl, Mark Tempes, George Anderson

11. Economic and Legal Aspects of Cloud Computing

Abstract
With regard to the economics of the cloud in the context of SAP’s Business Suite applications and NetWeaver technical underpinnings, there is no single right answer for every customer or cloud hosting provider. Cloud computing affects and is just as greatly affected by a number of broad economic and legal factors.
Michael Missbach, Thorsten Staerk, Cameron Gardiner, Joshua McCloud, Robert Madl, Mark Tempes, George Anderson
