TrendMiner’s PlantIntegrations can be installed as WebHost (IIS) or AppHost (self‑hosted). AppHost is a lightweight, simpler alternative that is easier to install, maintain and upgrade. While WebHost currently still provides more flexibility and security features. There is a difference in available features before version 2026.R1.0 and after 2026.R1.0 which is explained below.

 

Deployment features before version 2026.R1.0:

 

These are the most important differences between the two hosting options:

Feature WebHost (IIS) AppHost (Self‑hosted)
Installation IIS setup Simple exe, self‑contained
Port configuration Flexible Fixed to 8001
Security TLS/HTTPS, Basic Auth Relies on network/proxy security
Multiple instances X Single instance (fixed port)
Best for Complex environments needing full control Lightweight setups or quick deployments

 

Summary:

  • AppHost is currently ideal for small or lightweight setups, quick deployment, and simpler maintenance.

  • WebHost is currently still preferred when you need multiple instances on one server, advanced security features or you can’t use port 8001.

 

Improvements to AppHost starting from version 2026.R1.0

 

Below in bold, you can see the improvements which will be made to the AppHosted deployment option:

Feature WebHost (IIS) AppHost (Self‑hosted)
Installation IIS setup Simple exe, self‑contained
Port configuration Flexible Flexible
Security TLS/HTTPS, Basic Auth TLS/HTTPS, Basic Auth
Multiple instances X Not yet supported
Best for / Preferred method which can now also be used in Complex environments needing full control

 

Summary

  • AppHost is now the preferred way of installing PlantIntegrations since the same security features and port flexibility will be available, in addition to the simple installation and upgrade procedure.

  • WebHost is still supported and can be deployed if necessary.

Hey,

should these options only be considered for new installations or are there cases in which we should consider a change of the deployment for existing installations?

Hi Sören,

As of the upcoming 2026.R1 release the AppHost would be the preferred option. Short to mid term the WebHost will go into maintenance mode and we will stop developing new features for the WebHost.

At that time we will actively communicate to migrate from WebHost to AppHost. With the built-in migration tool this will be low effort.

 

So to answer your question in short:

  • For new connector installations as of the 2026.R1 we would recommend the AppHost.
  • For existing connector installations as of the 2026.R1 you can keep using the WebHost version for now but eventually a migration will be required so you can already migrate.
