Hi ,
I think in your case the single point of entry/failure is still Machine
A. even if have multiple CCs , we will still have single point of
failure on ClC/Walrus level .
correct me if i am wrong please

Hi Ziv,
yes thank you. If I install on two machines a CC like in the example
with 5 physical machines:
machine A: CLC/Walrus
machine B: CC1/SC1
machine C: NC1
machine D: CC2/SC2
machine E: NC2
Do the CC1 and CC2 and also the SC have automatically the same
information? Or do I need to configure something like a Hot-Standby
between both machines (in this example B and D) ?
Cheers,
Bjoern

Hi Björn,
I guess you might be confused due to subtle semantics, it doesn't
say it SHOULD be 1 CC, it says at least, the minimal requirement
(not recommended for production environments) is to have 2
machines, but the more, the merrier.
Please take a look at the different possible topologies in the
link below:
https://help.ubuntu.com/community/UEC/Topologies
Hope this helps,
Ziv

Hi everyone,
According to
https://help.ubuntu.com/community/UE...nstallSeparate
<https://help.ubuntu.com/community/UEC/PackageInstallSeparate>, there
should be only 1 Cloud Controller (CLC) and, as I read the
page, only 1 Walrus Controller. (WS3)
What would happen is 1 of these crash?
Is there a recommended solution for backup an UEC Configuration?
