Azure Stack Hub and operational excellence

  • Article

Azure Stack Hub is a hybrid cloud platform that lets you provide Azure services from your datacenter. It provides a way to run apps in an on-premises environment.

This service unlocks the following hybrid cloud use cases for customer-facing and internal line-of-business apps:

  • Edge and disconnected solutions: Addresses latency and connectivity requirements by processing data locally.
  • Cloud apps that meet varied regulations: Allows you to develop and deploy apps with full flexibility to meet regulatory or policy requirements.
  • Cloud app model on-premises: Provides Azure services, containers, serverless, and microservice architectures to update and extend existing apps or build new ones.

For more information, reference Azure Stack Hub overview.

To understand how Azure Stack Hub supports operational excellence for your application workload, reference the following articles:

The following sections include design considerations, a configuration checklist, and recommended configuration options specific to Azure Stack Hub and operational excellence.

Design considerations

Azure Stack Hub includes the following design considerations:

  • Microsoft doesn't provide an SLA for Azure Stack Hub because Microsoft doesn't have control over customer datacenter reliability, people, and processes.
  • Azure Stack Hub only supports a single Scale Unit (SU) within a single region, which consists of between four and 16 servers that use Hyper-V failover clustering. Each region serves as an independent Azure Stack Hub stamp with separate portal and API endpoints.
  • Azure Stack Hub doesn't support Availability Zones because it consists of a single region or a single physical location. High availability to cope with outages of a single location should be implemented by using two Azure Stack Hub instances deployed in different physical locations.
  • Apply general Azure configuration recommendations for all Azure Stack Hub services.

Checklist

Have you configured Azure Stack Hub with operational excellence in mind?

  • Treat Azure Stack Hub as a scale unit and deploy multiple instances to remove Azure Stack Hub as a single point of failure for encompassed workloads.

Configuration recommendations

Consider the following recommendation table to optimize your Azure Stack Hub configuration for operational excellence:

Recommendation Description
Treat Azure Stack Hub as a scale unit and deploy multiple instances to remove Azure Stack Hub as a single point of failure for encompassed workloads. Deploy workloads in either an active-active or active-passive configuration across Azure Stack Hub stamps or Azure.
