Load Balancing Cloudstack Management Servers

[Glenn Wagner <gl...@blackeye.co.za>]

Good day,

When trying to load balance two Cloudstack Management servers which 
ports should be exposed so that the management function will still work


port 8080/443
port 8250
port 8096

Second question , just a confirmation if using two CS management server 
, a separate NFS server should be used.

Thanks
Glenn Wagner

8250/9090 = loadbalnced internaly only for client access
8080/8096/443 - loadbalanced externaly for public access - but remove the
8080 really...

NFS location - is your preference - preferably NOT on the mgmt nodes, but
can be anywhere really.

Hi Glenn

Assuming you are going to use the same Load Balancers for inbound access to the GUI by your customers, and you are going to put the SSL Cert on the LBs, then you need to load balance 443 which maps to 8080 on the Management Servers.

If the same LBs are also handling the traffic from the System VMs (they normally do) then you need to load balance 8250.

If you need to have the 'un-authenticated api port' enabled for say use with Cloud Portal Business Manager and you want to pass this traffic through your load balancers, then ensure it is only accessible from a private internal network, and NEVER expose to the public internet etc.

Regarding NFS, yes, if using multiple Management Servers, they should just be Management Servers and not providing any other services etc
