I have 2 apps servers and 2 WFE servers, I would like to have high availability configuration for SharePoint central admin. So that if one apps server goes down, another apps server will be active. I need to know steps to configure this topology. Do I need to host CA in both the apps server?

  • When you configure the central admin select the app server for hosting as mentioned in the blog. Web application on wfe is business as usual

  • You should always host Web Applications on all servers. SharePoint 2010/2013's topology service isn't smart and will route requests that cannot be served to servers that do not run the Foundation Web service.
