Scalability and performance of a virtualized SAP system

چکیده
Enterprise resource planning systems (ERP), like SAP systems, build the backbone of the business processes in today’s large enterprises. This is why a weak performance of a SAP system tremendously decreases the performance of the user and thus of the enterprise. Today many SAP hosting providers make use of virtualization techniques, but disregard the impact of such solutions. In this paper we focus on the impact of virtualization solutions on the performance of SAP systems and follow a quantitative approach to ascertain several benchmark results. We make four contributions: 1) On the basis of a quantitative investigation we give a recommendation how to configure a SAP system for heavy workload. The recommendation helps to avoid hardware resource shortage. 2) We show that the average performance of a SAP system increases up to +2% if a container-based virtualization solution is used. 3) We show that the performance of a SAP system is decreased up to -33% if a Xen-based virtualization solution is used. 4) On the basis of the quantitative results we give recommendations for a new sizing process in order to meet the requirements for virtualized SAP systems.

Experimental Evaluation of the Performance-Influencing Factors of Virtualized Storage Systems
Virtualized cloud environments introduce an additional abstraction layer on top of physical resources enabling their collective use by multiple systems to increase resource efficiency. In I/O-intensive applications, however, the virtualized storage of such shared environments can quickly become a bottleneck and lead to performance and scalability issues. In software performance engineering, app...
متن کاملPerformance Implications of the Number of Virtual CPUs in a Large Telecommunication Application
One of the major advantages of cloud environments is scalability in terms of allocating more resources to an application if needed. On the other hand, high performance and high resource utilization are important goals in a cloud environment as well. In this paper, we have shown that overall system performance is sensitive to appropriate allocation of resources (e.g., CPU), and there are other f...

We propose Hi-sap, a Web server system that solves internal security problems in a server used for shared hosting services and that achieves high site-number scalability with little performance degradation. Customers are often exposed to internal attacks, i.e., malicious customers illegally access other customers’ files. Existing approaches solve a portion of this problem, but they are not enou...
متن کاملCharacterizing the Performance and Scalability of Many-core Applications on Virtualized Platforms
Clouds have become attractive to applications, because of its low cost and on-demand computing model with the use of virtualization technologies. With the continual increasing number of cores per chip, it should be an emergence to study and improve the scalability of virtualized platforms. This paper tries to make a study on the horizontal scalability 1 of a set of parallel applications on virt...
