Adding to Andrea's.
We used to deplou GWC separately in the past for a number of reasons:
- diskquota did not work in a cluster hence when we had multiple
geoserver in parallel using embedded GWC was not an option
- gwc integration in geoserver was still a bit unstable
- more control over the configuration
- easier to scale them independently
As of today we are pushing towards keeping them integrated which makes
deployments simpler, however there is still one thing on the wishlist
that would make the integrated GWC my #1 option without doubts and
that would be the ability to distinguish WMS requests that are routed
transparently to GWC from those that are not in the control flow
plugin.
It is infact impossible today to create a QOS strategy that
differentiate this use case when GS and GWC are integrate and that can
be painful when you are serving thousands of users with the same
cluster. Of course, you can dedicate different groups of isntances to
different roles but that's not different than using GWC standlone.

Hi,
It is commonly mentioned to use a standalone geowebcache instance when
serving multiple geoserver instances and to improve performance in
production environments for a high load of customers. For example the
following blog from GeoSolutions:
http://www.geo-solutions.it/blog/real-world-uses-cases-troubleshooting-large-geoserver-deployment/
<http://www.geo-solutions.it/blog/real-world-uses-cases-troubleshooting-large-geoserver-deployment/>
Right, this is one of the few cases in which we still deploy a stand-alone
GWC.
But look at the numbers, we are talking about thousands of requests per
second... in this situation
it's indeed a good idea to keep it separate, mostly to avoid the sheer
number of requests
GWC is receiving to dominate your tomcat instance, and leaving little space
to wms/wfs.
But if you don't have such a demanding deploy, keeping the integrated one
it's easier
and it's (by far) the more common choice.
Cheers
Andrea
