BSH Hausgeraete: Operating IT Systems Simply and Securely in 50 Countries BSH Hausgeraete GmbH puts quality first not just in its products, but in its IT. This is why the company chose to upgrade its databases and switch to the SAP HANA platform. To facilitate the migration, and to simplify its global IT operations, BSH now uses SAP Landscape Virtualization 2.1* software. *As of September 2016, this offering will be available under the name SAP Landscape.

Simplifying operations of SAP software Anyone wanting to purchase a new oven need look no further than BSH Hausgeraete GmbH. Founded as a joint venture between Bosch and Siemens, the company has 42 factories for production and 80 subsidiaries in 50 countries. Its IT landscape has grown dramatically to keep pace. IT executives now manage over 180 SAP software systems, some of which include up to 12 software instances. Understandably, it was difficult to maintain an overview of such a complex software landscape. Dependencies between the SAP software systems as well as dependencies between operational software and the databases had to be known. The company had to be able to shut down and restart databases without causing disruption to the business. Until now, this required the support of experts. As the software landscape grew, so did the need for specially trained employees. To meet the ever-increasing demands without changing staff, the Enterprise Application Platform team had to cut operating costs and optimize operational processes. The key was SAP Landscape Virtualization software together with the SAP HANA platform. To ease the migration to SAP HANA, BSH looked to standardize and simplify SAP software operations worldwide. 2 3 minutes Required to relocate one instance 3 / 8
Gaining thorough understanding more quickly and easily Even though BSH s national subsidiaries are widely distributed, the vast majority of its IT is run at a central data center in Munich, Germany. The company relies on virtualization to increase its flexibility and agility. The virtual concept proved effective, but it simplified administration only slightly. Numerous instances can run on the same server, so you have to be very careful what you do, says Markus Schmitt, project manager of BSH. The IT executives at BSH got to know SAP Landscape Virtualization at Bosch. It simplified all important administrative tasks in physical and virtual environments. Doreen Beitlich, head of the Enterprise Application Platform team at BSH, saw it was the right solution. Besides showing the systems and instances running on each host and the relationships between them, it provides essential information on CPU and memory usage of the hosts. Employees can keep operations running smoothly without extensive knowledge of the IT architecture. In the past, administrators needed to know which IP addresses and which definitions belonged to which system, says Schmitt. We used to use a wiki site for this but that was not easy to maintain. Today, SAP Landscape Virtualization maps everything. Fifteen employees working in three shifts maintain operations of the BSH infrastructure. With SAP Landscape Virtualization, they pause systems if needed and restart them or move them from one server to another all with a mouse click. When we restart systems, we need to do things in the right order and know all dependencies that was where mistakes could be made. Thanks to SAP Landscape Virtualization, that is now a thing of the past. Markus Schmitt, Project Manager, BSH Hausgeraete GmbH 4 / 8
Effectively administering virtual instances of SAP software As part of its SAP strategy, BSH is gradually migrating its SAP software systems to SAP HANA. The company uses SAP Landscape Virtualization to administer both the original enterprise resource planning (ERP) landscape and the new SAP HANA landscape. A newly established Global Infrastructure Operations team now maintains the entire infrastructure around the clock. The team can immediately rectify any issues to ensure high system availability. For all actions triggered in SAP Landscape Virtualization, every process step can be recorded a major advantage for audits. The software also supports the SAP HANA transformation process, which makes the team s work much easier. The SAP HANA landscape was implemented in line with standards for SAP HANA tailored data center integration and strictly follows adaptive design principles from SAP. So, with the help of SAP Landscape Virtualization, instances can also be relocated in the SAP HANA environment. For BSH, the innovation lies in the shift of emphasis to strategic activities, which is enabled by simpler, partially automated IT operations processes. In addition, the team now has better transparency into the depth of the entire SAP system stack. Tasks that the infrastructure teams were responsible for in the original system landscape are now carried out by BSH s Enterprise Application Platform team using SAP Landscape Virtualization. 5 / 8

Safeguarding operations legally and technically SAP Landscape Virtualization creates transparency into the complex IT landscape. Instead of working around the clock, infrastructure experts now define processes in SAP Landscape Virtualization. The operations team can execute them in a few mouse clicks, when needed. By simplifying operations, experts have been freed up for strategic tasks. Relocation of entire systems runs just as smoothly when OS maintenance must be performed. Experts prepare the target system during normal working hours. With SAP Landscape Virtualization, they specify which components are to be relocated, for example, over the weekend. This means all preparation takes place during business hours. Downtime is limited to two to three minutes per instance, while the SAP software keeps running throughout the maintenance period. That was never possible before, says Schmitt. Every action is logged in SAP Landscape Virtualization for maximum transparency. If an employee wants to relocate a system that is currently in use, he can identify and notify the user. BSH has also enforced segregation of duties. It is important for the BSH team to prevent downtime and ensure high system availability. BSH uses asynchronous system replication into a second data center for SAP Landscape Virtualization to ensure it can quickly become operational again in case of disaster recovery. This also enables SAP Landscape Virtualization itself to be quickly restored. The software is crucial for the controlled startup of all associated systems after a disaster. The best-case scenario is when employees don t notice any changes at all just that their applications are running quickly and reliably. We ve got that now.

BSH Hausgeraete Looking forward to next-generation IT SAP Landscape Virtualization also enables automatic system provisioning. BSH has already performed the first successful tests. Application servers can be set up, copied, and renamed more quickly. In the future, we anticipate even more benefits in provisioning, says Schmitt. Today, new hosts are already automatically entered into SAP Landscape Virtualization. BSH is currently conducting a preliminary study for SAP S/4HANA software, with special focus on the SAP S/4HANA Finance solution. 40894 (16/08) 8 / 8 Picture Credit BSH Hausgeraete GmbH, Munich, Germany.
