This response doc helps tackle normal Requests for Info (RFI) with which IoTCoast2Coast empower clients to guage totally different choices out there place right this moment. Via the mappings accessible within the CCM, we are able to illustrate how Azure has applied safety and privateness controls aligned to different worldwide requirements similar to ISO/IEC 27001, US Authorities frameworks together with FedRAMP, and business certifications similar to PCI DSS.




A cloud-specific controls framework such because the Cloud Management Matrix (CCM) reduces the chance of a company failing to think about vital components when deciding on a cloud supplier. The chance is additional mitigated by counting on the cumulative information of business consultants who created the framework, and benefiting from the efforts of many choices.




For organizations that would not have detailed information concerning the totally different ways in which cloud suppliers can develop or configure their choices, reviewing a completely developed framework can present perception into easy methods to evaluate comparable choices and distinguish between suppliers. A framework may also assist decide whether or not a particular service providing meets or exceeds compliance necessities and/or related requirements.


Azure method on SAP Connectivity Requirement


Each Azure and the underlying Microsoft Cloud and Infrastructure Operations (MCIO) bodily environments make use of Community frameworks that span a number of greatest requirements.

Let’s allow a variety of enterprise and client providers with a extremely accessible, safe, and agile community


Azure ExpressRoute Problem


Azure ExpressRoute is the really useful Azure networking service to create a non-public connection between an on-premises community and Azure digital networks, bypassing the general public Web (see reference structure). That is relevant to each SAP S/4HANA in addition to SAP HANA on Azure Massive Situations deployments.


ExpressRoute permits the preliminary migration of the information property, in addition to the continued safe knowledge switch between your SAP on Azure resolution and functions remaining in your enterprise knowledge middle. Most organisations in Northern Europe deploy their SAP on Azure options on the Azure West Europe multi-zone area situated in The Netherlands.


Build Azure Network Foundation


There are couple of ExpressRoute nodes accessible in North America, affords <0.5 millisecond latency to SAP Hana on Azure and Massive Situations. To safeguard efficiency of SAP HANA in-memory databases, latency and jitter must be thought of when designing connectivity resolution.


As bodily distance immediately impacts latency and jitter, it’s really useful for purchasers planning to switch massive knowledge volumes and clients working hybrid cloud architectures to think about it critically.

Reference structure




Let’s This reference structure describes an enterprise-grade, production-level system. To fit your enterprise wants, this configuration will be diminished to a single digital machine. Nevertheless, the next elements are required,


Digital community


The Azure Digital Community service securely connects Azure assets to one another. On this structure, the digital community connects to an on-premises atmosphere by way of a gateway deployed within the hub of a hub-spoke topology. The spoke is the digital community used for the SAP functions.




The digital community is subdivided into separate subnets for every tier: gateway, utility, database, and shared providers.


Digital machines


This structure makes use of digital machines working Linux for the appliance tier and database tier, grouped as follows:


Software tier


Contains the Entrance-end Server pool, SAP Net Dispatcher pool, utility server pool, and SAP Central Providers cluster. For top availability of Central Providers on Azure Linux digital machines, a extremely accessible Community File System (NFS) service is required.


NFS cluster


This structure makes use of an NFS server working on a Linux cluster to retailer knowledge shared between SAP programs. This centralized cluster will be shared throughout a number of SAP programs. For top availability of the NFS service, the suitable Excessive Availability Extension for the chosen Linux distribution is used.




The database tier makes use of two or extra Linux digital machines in a cluster to attain excessive availability. HANA System Replication (HSR) is used to duplicate contents between major and secondary HANA programs. Linux clustering is used to detect system failures and facilitate automated failover. A storage-based or cloud-based fencing mechanism can be utilized to make sure the failed system is remoted or shut right down to keep away from the cluster split-brain situation.




Additionally referred to as a bastion host. It is a safe digital machine on the community that directors use to connect with the opposite digital machines. It will possibly run Home windows or Linux. Use a Home windows jumpbox for net searching comfort when utilizing HANA Cockpit or HANA Studio administration instruments.


Load balancers


Each built-in SAP load balancers and Azure Load Balancer are used to attain HA. Azure Load Balancer situations are used to distribute visitors to digital machines within the utility tier subnet.


Availability units


Digital machines for all swimming pools and clusters (Net Dispatcher, SAP utility servers, Central Providers, NFS, and HANA) are grouped into separate availability units, and at the least two digital machines are provisioned per function. This makes the digital machines eligible for the next service stage settlement (SLA).




Community interface playing cards (NICs) allow all communication of digital machines on a digital community.


Community safety teams


To limit incoming, outgoing, and intra-subnet visitors within the digital community, community safety teams (NSGs) are used.




A gateway extends your on-premises community to the Azure digital community. ExpressRoute is the really useful Azure service for creating non-public connections that don’t go over the general public Web, however a Web site-to-Web site connection will also be used.


Azure Storage


To supply persistent storage of a digital machine’s digital arduous disk (VHD), Azure Storage is required.


Highlights Networking structure for HANA Massive Occasion


The networking structure for HANA Massive Occasion will be separated into 4 totally different elements,


On-premises networking and ExpressRoute connection to Azure. This half is the shopper’s area and is linked to Azure by way of ExpressRoute. This Expressroute circuit is totally paid by you as a buyer. The bandwidth must be massive sufficient to deal with the community visitors between your on-premise property and the Azure area you might be connecting in opposition to. See the decrease proper within the following determine.


Azure community providers, as beforehand mentioned, with digital networks, which once more want ExpressRoute gateways added. This half is an space the place you should discover the suitable designs to your utility necessities, safety, and compliance necessities. Whether or not you employ HANA Massive Occasion is one other level to think about by way of the variety of digital networks and Azure gateway SKUs to select from. See the higher proper within the determine.


Connectivity of HANA Massive Occasion by way of ExpressRoute expertise into Azure. This half is deployed and dealt with by Microsoft. All you should do is present some IP tackle ranges after the deployment of your property in HANA Massive Occasion join the ExpressRoute circuit to the digital networks. For extra info, see SAP HANA (Massive Situations) infrastructure and connectivity on Azure. There is no such thing as a extra payment for you as a buyer for the connectivity between the Azure knowledge middle community cloth and HANA Massive Occasion models.


Networking inside the HANA Massive Occasion stamp, which is generally clear for you.

The variations to SAP deployments in Azure

  • The HANA Massive Occasion models of your buyer tenant are linked by way of one other ExpressRoute circuit into your digital networks. To separate load situations, the on-premises to Azure digital community ExpressRoute circuits and the circuits between Azure digital networks and HANA Massive Situations do not share the identical routers.
  • The workload profile between the SAP utility layer and the HANA Massive Occasion is of a special nature, with many small requests and bursts like knowledge transfers (end result units) from SAP HANA into the appliance layer.
  • The SAP utility structure is extra delicate to community latency than typical situations the place knowledge is exchanged between on-premises and Azure.
  • The Azure ExpressRoute gateway has at the least two ExpressRoute connections. One circuit that’s linked from on-premise and one that’s linked from HANA Massive Situations. This leaves solely room for an additional two extra circuits from totally different MSEEs to connect with on ExpressRoute Gateway. This restriction is unbiased of the utilization of ExpressRoute Quick Path. All of the linked circuits share the utmost bandwidth for incoming knowledge of the ExpressRoute gateway.

HANA Massive Occasion models in a number of areas


To understand catastrophe restoration set ups, you should have SHANA Massive Occasion models in a number of Azure areas. Even with utilizing Azure [Global Vnet Peering], the transitive routing by default isn’t working between HANA Massive Occasion tenants in two totally different areas. Nevertheless, International Attain opens up the communication path between the HANA Massive Occasion models you might have provisioned in two totally different areas. This utilization state of affairs of ExpressRoute International Attain permits,

  • HANA System Replication with none extra proxies or firewalls
  • Copying backups between HANA Massive Occasion models in two totally different areas to carry out system copies or system refreshes.
Build Azure Network Foundation


The determine reveals how the totally different digital networks in each areas are linked to 2 totally different ExpressRoute circuits which can be used to connect with SAP HANA on Azure (Massive Situations) in each Azure areas.
