Given the mission-critical nature of SAP applications, high availability, and performance for SAP environments is a primary focus for IT organizations. With several options that allow for a dynamic, resource optimized IT environment, organizations are increasingly expanding their SAP NetWeaver / S/4HANA footprint in the public cloud. While cloud services offer attractive SLA's, it's important to understand that they are not application-aware, and running SAP applications in the public cloud doesn't eliminate the risk of downtime or data loss. Veritas InfoScale Enterprise helps minimize these risks and mitigates single points of failure in cloud environments, to keep your SAP applications up and running in the cloud all the time.
Veritas InfoScale is a software-defined optimization solution for mission-critical applications that abstracts applications from their underlying hardware and software resources. That abstraction enables enterprise-grade optimizations around business continuity, performance, and infrastructure agility across physical, virtual, and cloud environments.
InfoScale has advanced integration with both Azure and SAP NetWeaver / S/4HANA that is key to building a highly available SAP environment in Azure:
Now that we know more about how InfoScale works, let's talk about how to implement a highly available SAP NetWeaver / S/4HANA environment in Azure using InfoScale Enterprise.
InfoScale makes it easy to provide high availability and disaster recovery for SAP workloads with customized agents for Azure, NetWeaver, S/4HANA, and SAP HANA databases. InfoScale protects the SAP components that are critical for overall application availability in a distributed SAP environment:
These SAP components are associated with your Azure disk, IP, and DNS resources. When a resource managed by InfoScale fails, InfoScale can detect the failure and initiate a failover operation to a secondary node or standby cluster in a different Azure zone or region. Figure 2 shows the typical deployment architecture of an SAP NetWeaver / S/4HANA application server with an SAP supported database in Azure across Availability Zones. For more information on how InfoScale interacts with Azure, take a look at InfoScale on Azure: Integration and Implementation.
InfoScale supports several highly available deployment scenarios for SAP NetWeaver / S/4HANA instances in Azure:
Are you concerned about operating costs? InfoScale also helps manage and optimize costs in the cloud. In Azure, you can create and optimize SAP instances for development, testing, or production environments. If an SAP production application instance outage occurs, InfoScale manages the instance failover between the designated SAP systems without disrupting the client connections. This reduces the overall total cost of ownership in case of a disruption or outage of SAP instances in Azure. Figure 3 shows how this works.
So, we've talked about high availability and DR, but what about SAP application performance? The Flexible Storage Sharing (FSS) feature included with InfoScale Enterprise is a unique feature that provides high performance shared storage in Azure using storage services directly attached to Azure VM's. Figure 4 shows an example of how this works. FSS supports all Azure storage services. InfoScale's volume manager, file system, and FSS feature are proven options for maximizing application performance and can be used with S/4HANA and SAP NetWeaver application servers as well as most database management systems (not currently supported with SAP HANA databases). More information on FSS can be found here.
