Hi, -original message- Subject: Re: [Dev] Autoscaling with LXCs demo -2 From: Sajith Kariyawasam <[email protected]> Date: 06/05/2012 1:43 am
Further, we will need to investigate as to why it takes more than expected time for the LB to receive the 'Join' message when an app server is started inside a container Ahhh.. yes! We need to test without using LXCs and see whether the issue remains. Also, it was suggested that we should test this with multiple domains (not only AS, but also ESB.. etc) For this we need to fix the issue i mentioned above regarding in-mediator. And I see that Sanjeewa is in the process. Regarding the introductory presentation, I think its better to add Agent registration part and some of the controller's functionalities (persistence) so that the overall picture gets more clearer. Yes, it needs to cover whole picture, i'll try ma best to do it despite i'm on a pilgrimage :) On Fri, May 4, 2012 at 8:52 PM, Nirmal Fernando <[email protected]> wrote: > Hi All, > > Today we had another demo. > > Participants were: Azeez, Srinath, Dimuthu, Damitha, Sameera, Pradeep, > Ranga, Lahiru, Sajith and myself. > > First we gave a brief overview of the autoscaling architecture.
