RELIABILITY OF SAP SYSTEMS IN AZURE EVALUATING THE RELIABILITY OF SAP SYSTEMS ON MICROSOFT AZURE: METRICS, CHALLENGES, AND BEST PRACTICES

Abstract

With more and more enterprises deploying mission-critical SAP applications in cloud environments, reliability should be the priority issue. The Azure service has gained popularity because of its high cloud infrastructure, compliance that is a prerequisite for an enterprise, and ability to support SAP-certified workloads. However, the switch between the traditional on-premises IT landscape and the cloud creates a different set of issues and aspects of uptime, consistent performance, disaster recovery, and service-level agreement (SLA) compliance. The article assesses trustworthiness on SAP systems hosted on Microsoft Azure and an analysis that gives a specific assessment on how cloud-native capabilities, architecture decisions, and predictive monitoring plans alter the performance of the system, as well as business continuity. Depending on the SAP workload, Azure offers high availability (HA) and disaster recovery (DR) services with specific technical underpinnings explored in the study, which can be used to gather optimal information on optimizing uptime and minimizing any potential unplanned disruptions. HOW- Reliability SLA metrics such as MTTB, MTTB, fault tolerance, latency, and SLA alignment are specified and put into context specific to SAP use case scenarios. Moreover, this paper also summarises the major pitfalls enterprises encounter as they migrate to the cloud and operate on a day-to-day basis, such as network latency and VM placement, patching, and configuration drift. This paper brings together the practical experiences of a modern enterprise with a best practice model and, therefore, provides IT architects, SAP administrators, and decision-makers with practical solutions that they can use to enhance reliability. The tables scattered across the article cross-reference Azure-native tools and SAP reliability requirements, discuss typical HA/DR trends, and describe potential future methods of improving resilience. The idea will also be to make up the difference between the SAP dependability demands and the developing capabilities of Azure, so it will be feasible to keep enterprise workloads uniformly available, secure, and delivering.
