Re: [openstack-dev] [heat][senlin] Action Required. Idea to propose for a forum for autoscaling features integration
Thanks for getting the forum setup. I have added some high-level autoscaling use case to the etherpad that will help during the discussion.

As far as duplicated effort is concerned (that's the only justification I could get from the etherpad), possibly senlin duplicated some stuff expecting to replace heat implementation in time. Also, we've not made any feature additions to heat group resources since long time (expecting senlin to do it instead) and I've not seen any major bugs reported by users.

But, what I wonder is "why a user would want to do a delete in a controlled batched manner"? The only justifications provided is that "they want to throttle requests to other services, as those services are not able to handle large concurrent requests sent by heat properly". Are we not looking at the wrong place to fix those issues? IMHO, a good list of user issues on the mentioned etherpad would really help justify the effort needed.

What matters most is the usage scenarios we support. I don't think users care that much how project teams are organized. Yeah, I mostly agree with you, and in fact I often use the term 'scaling group' to encompass all of the different types of groups in Heat. Our job is to provide an API that is legible to external tools to increase and decrease the size of the group. The 'auto' part is created by connecting it with other services, whether they be OpenStack services like Aodh or Monasca, monitoring services provided by the user themselves, or just manual invocation. (BTW people from the HA-clustering world have a _very_ negative reaction to Senlin's use of the term 'cluster'... there is no perfect terminology.) Hi all, as we start to discuss how can we join develop from Heat and Senlin as we originally planned when we decided to fork Senlin from Heat long time ago. IMO the biggest issues we got now are we got users using autoscaling in both services, appears there is a lot of duplicated effort, and some great enhancement didn't exist in another service. As a long-term goal (from the beginning), we should try to join development to sync functionality, and move users to use Senlin for autoscaling. So we should start to review this goal, or at least we should try to discuss how can we help users without break or enforce anything. The original plan, iirc, was to make sure Senlin resources are supported in Heat, This happened. and we will gradually fade out the existing 'AutoScalingGroup' and related resource types in Heat. That's almost impossible to do without breaking existing users. I have no clue since when Heat is interested in "auto-scaling" again. It's something that Rico and I have been discussing - it turns out that Heat still has a *lot* of users running very important stuff on Heat scaling group code which, as you know, is burdened by a lot of technical debt. What will be great if we can build common library cross projects, and use that common library in both projects, make sure we have all improvement implemented in that library, finally to use Senlin from that from that library call in Heat autoscaling group. And in long-term, we gonna let all user use more general way instead of multiple ways but generate huge confusing for users. The so called "auto-scaling" is always a solution, built by orchestrating many moving parts across the infrastructure. In some cases, you may have to install agents into VMs for workload metering. Totally agree, but... I am not convinced this can be done using a library approach. Clearly there are _some_ parts that could in principle be shared.

We should strive to minimize the technologies users have to master when they have a need. +1 - to expand on Rico's example, we have at least 3 completely separate implementations of batching, each supporting different actions: Heat AutoscalingGroup: updates only Heat ResourceGroup: create or update Senlin Batch Policy: updates only and users are asking for batch delete as well. This is clearly an area where technical debt from duplicate implementations is making it hard to deliver value to users. cheers, Zane.

Hi Rico, I'm the Senlin PTL and would be happy to have a forum discussion in Berlin about the future of autoscaling.
