Power Apps | On-premises data gateway | High-availability Clusters

In one of my previous articles, I detailed the steps to connect to an on-premise SQL server from a Canvas App.

High availability: Refers to a set of technologies that minimize IT disruptions by providing business continuity of IT services through redundant, fault-tolerant, or failover-protected components inside the same data center.

By default On-premise Gateway is single instance and not a High availability option. If the gateway is unavailable, data requests will be failed and causes App downtime.

In this article, lets see how to build an high available On-premises Gateway using Clusters.

Gateway Clusters:

  • A cluster lets gateway admins avoid having a single point of failure for on-premises data access.
  • If the primary gateway is unavailable, data requests are routed to the second gateway that you add, and so on.
  • Following is the option to add a new Gateway to add to an exiting Gateway Cluster.
  • Because we can install only one standard gateway on a computer, we must install each additional gateway in the cluster on a different computer.

Refer this Docs article for more details.
