[Fiware-lab-federation-nodes] experiences with HA

[FERNANDO LOPEZ AGUILAR]

Dear Seán,

I started to configure Juno in HA but we observed that with the traffic and number of user increased a lot the system does not work properly and it was the reason of the problems that we have during May this year that finally went to configure the system in single node mainly related to the neutron service. For sure you can deploy the different API services in HA due to they are stateless and should not produce any error on it.

Subject: [Fiware-lab-federation-nodes] experiences with HA

Hi all,

We're looking at our upgrade strategy and we're curious to
hear any experience with Kilo HA both from the deployment
perspective as well as the operations perspective.

From xifi, I remember Fanis reporting a split-brain scenario
with HA and in the end he opted not to go with a HA solution;
this gives me pause for thought when considering this
deployment solution, even though it seems to be the
preferred solution.

Generally, we would be well disposed to a HA deployment
as we would like to learn about it, but we do not want to
end up deploying a technology that is too far from production
readiness.

Does anyone have any experience that they can share on this
point?

BR,
Seán.
