Description Sergio G. 2020-03-03 17:10:01 UTC
Document URL: 
- https://docs.openshift.com/container-platform/4.3/installing/installing_bare_metal/installing-bare-metal.html
- https://docs.openshift.com/container-platform/4.3/installing/installing_vsphere/installing-vsphere.html


Section Number and Name:
- installation-network-user-infra_installing-bare-metal -> Load balancers


Describe the issue:


Only the ports detail are provided but some other points should be documented:
 - is any load balancing algorithm preferred? If not, a note should be added that customer can choose the algorighm at their convenience.
 - is recommended to use TCP check or HTTP check?
 - in case of recommending an HTTP check, which URL should be monitored in the backend servers?
 - is there any recommended configuration for the check? Any value for timeout or retries? This might be important when applying configurations using MCO or updates so a suggestion for the customers might help.
 - is supported SSL offloading? Does it have any caveats/concerns when using it? 


Additional information:
This can be as easy as describing as a reference the configuration done by the IPI installer in AWS.

Hi Pablo, thank you for updating the requirement with the latest comments.
Hi Latha, re-assigning this to you per our conversation since it seems to have OCP core touch points.

@lmurthy Thank you, reviewing now.
@palonsor I have been assigned this case, reviewing now. Do you have more thoughts or comments?
