zenoss 5 docker installation overview

Hello,

I have an older version of zenoss core 4 installed and in production under heavy use, company I work for has obtained support for commercial zenoss but support questions I have asked I am not satisfied with.

Can someone with some expierience in zenoss 5 give me some feedback on wth with all the different installation docker combos ?

i.e. I know control center is the heart of it all and needs to be installed 1st.

so far after that I believe as of today perhaps

1) resource manager is a different flavor of zenoss with additional zenpacks?

2) zenoss.core is the striped down version of zenoss that perhaps is limited

3) service impact is an addon? for resource manager? or zenoss.core or both? it gives pretty flow diagrams if something is down? ( don't really have a use for that but I am sure some people might)

4) analytics name said same as above with possible enhancements for reporting.

do I have this correct?
