OTRS Multi Tier

[ToHo14]

Hi all

Sorry for asking so dump, but is it supported to install OTRS in the following way. The system is distributed over 3 physical servers OTRS Frontend Server 1, OTRS Frontend Server 2, OTRS DB Server. The two front end servers do not have a database and use the same database on the third server. Goal is to have frntend server in the DMZ and one in the Intranet using the same database and the same data. Is this supported? Is there documentation about such configurations?

Thanks.

Support for such a configuration may be from someone you'd pay for such support.

The concept of a single point of failure^W^W^W database source is reasonable as long as your configuration has only one iteration of obtaining tickets via email.

Thank you for the answer. With supported I meant if it's technically working. Is there any best poracties guide for large OTRS installations?

I don't really know if there's a posted answer in docs for that. Note that the given docs are a standardized single-server installation ... you may consider a reverse proxy (Don't ask me how) to provide load balancing rather than multiple installs.

I don't know your intended utilization/load, but at the point you're already looking at multiple front-end installations, you may want to look at load balancing on the database side as well.

From a generic point of view, almost all transactions are going to be of a type "insert" or "read", and generally have no math associated with their presence. (Time accounting sum is an exception to the rule).

However, the database interface is rather abstract and generic. Whatever you use is acceptable and multiple simultaneous same-web-server interactions with the database should not be appreciably different from multiple simultaneous different-web-server interactions with the database.
