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. Then we started the demo. We were able to demo end-end (LB -> Controller --> Agent) scenario for spawning an instance (through LB sanity check) and termination of an instance (through scaling down call) within a LXC container. Few suggestions came up: 1. Create separate carbon instances (rather than using Appservers) for controller and agent. 2. Create a simple UI for controller to show instances spawned in each adapter, instances belong to a particular domain etc. 3. Fixing the domain related issue in AutoscaleInMediator (This arose with the changes in loadbalancer.conf to reflect tenant aware load balancing). 4. Fixing the routing issue using Azeez's fix to Axis2. 5. Make scaling up demonstrable using a back-end service which has some processing (or having a Thread.sleep(..) call). Please add anything I've missed! PS: We'll repeat the demo next week (hopefully with some more improvements next week, for Sanjiva, Paul and anyone interested). -- Thanks & regards, Nirmal Software Engineer- Platform Technologies Team, WSO2 Inc.
