I'm upgrading from Tridion 2011 to Web 8. The current situation is like this: On production Live, we have 2 CD servers which are basically a copy of eachother. Both contain a deployer, broker database, file system for binaries and a website. Requests to the website are load balanced and in the publication target we have a destination for each server.

I am now trying to figure out how to set up topology manager for this scenario. The idea was to have a discovery service on each server, add 1 topology type and 2 CdEnvironments (1 for each server). But I don't understand how to create the TtmWebsite, as I can only enter 1 CdEnvironmentId. Do I have to add 2 websites (1 for each server)? If so, both use the same url (load balanced) and the PS scripts gives errors saying this baseURL already exists.

Is this scenario still supported or should we migrate to a single deployer/broker setup? Please advise.

A scaled-out/load-balanced CD Environment should be modeled as a single CdEnvironment in Topology Manager.

You should not try to do something like mirroring on two separate CD Environments; multi-destination support was intentionally removed in SDL Web 8, because it doesn't really work.

High Availability of the Deployer can be achieved using an Active/Passive (fail-over) configuration.

  • Can you please provide details on setting active/Passive deployer and also how can we do load balancing for content service?

  • This is really down to just infrastructure; proper use and configuration of load balancers. Sep 20, 2016 at 17:54
  • This setup was supported in 2011. Does your answer mean this cannot be done with Topology Manager?

  • The limitation is not in Topology Manager; Topology Manager models logical Environments and a scaled-out CD Environment is one logical Environment. Sep 20, 2016 at 18:35
  • So the current way of infrastructure with 2 deployers and 2 broker databases is not supported anymore and cannot be configured with topology manager?
