Choose deployment options with Azure Center for SAP solutions
When you deploy S/4HANA infrastructure with Azure Center for SAP solutions (ACSS) there are infrastructure deployment options you can select, depending on your use case:
- Distributed with High Availability (HA) creates distributed HA architecture. This option is recommended for production environments. If you choose this option, you need to select a High Availability SLA. Select the appropriate SLA for your use case:
- 99.99% (Optimize for availability) shows available zone pairs for virtual machine deployment. The first zone is primary and the next is secondary. Active ASCS and Database servers are deployed in the primary zone. Passive ASCS and Database servers are deployed in the secondary zone. Application servers are deployed evenly across both zones. This option not shown in regions without availability zones, or without at least one M-series and E-series virtual machine SKU available in the zonal pairs within that region.
- 99.95% (Optimize for cost) shows three availability sets for all instances. The HA ASCS cluster is deployed in the first availability set. All Application servers are deployed across the second availability set. The HA Database server is deployed in the third availability set. No availability zone names are shown.
- Distributed creates distributed non-HA architecture.
- Single Server creates architecture with a single server. This option is available for nonproduction environments only.

You can use latest if you want to use the latest image and not a specific older version. If the latest image version is newly released in marketplace and has an unforeseen issue, the deployment can fail. If you're using Portal for deployment, we recommend choosing a different image sku train (for example, 12-SP4 instead of 15-SP3) until the issues are resolved. However, if deploying via API/CLI, you can provide any other image version that is available. To view and select the available image versions from a publisher, use the following commands:
Get-AzVMImage -Location $locName -PublisherName $pubName -Offer $offerName -Sku $skuName | Select Version
Where, for example:
$locName = "eastus"
$pubName = "RedHat"
$offerName = "RHEL-SAP-HA"
$skuName = "82sapha-gen2"
You can start your ACSS-based deployment after you choose a deployment option, SAP software and OS; and have provisioned the necessary infrastructure and prerequisites.
