Thanks for your future sharing of your work on an opensource autoscaler
We would be interested at Orange to use the autoscaler, and potentially
try to plug into it the autosleep service  we're working on, so that a
minimum instance count the autoscaler could set could be equal to zero.
To me, one important missing aspect to make use of an autoscaling service
to handle changes in workloads, is to effectively handle newly instanciated
cold instances (i.e. whose lazy initialized caches are not yet warm, and
which would degrade user perceived experience if given immediately a fixed
% of the traffic):
- either to have support for autoscaling service to send warmup http
requests to newly created instances (similar to GAE warmup support)
- have the gorouter support a traffic ramping setting, so that a cold
instance is slowly getting traffic when entering rotation.

App auto-scaling is much needed feature for CF OSS , lot of users want to
use this functionality .
Once on the incubator, roadmap can be discussed. Hope to to see it soon
on cf incubator .

At Fujitsu we’re developing app auto-scaling and are considering to
propose moving it to the cf incubator.
Before we start open-sourcing it, I wanted to ask if there is any
interest for this in the community, possibly even others working on or
considering to work on one who’d be interested to collaborate/align with us?
We’re looking at providing basic support for scaling up/down based on
metrics like CPU, request count, and a service broker to enable it for your
We can share a detailed functional description for review in a few weeks.
Depending on priorities, interest and resources available we may add
functionality like sending an email notification in addition to/instead of
scaling, or scale based on other metrics (including app generated custom
Either way, we want to make these things pluggable to allow people to
integrate it with their own (closed-source) monitoring agents or custom
I feel every PaaS comes with free app auto-scaling functionality (PCF,
Bluemix, OpenShift, AWS, …) so OSS CF deserves one too.
I have discussed this plan with Pivotal and they have encouraged me to
send this email to the list.
Please let me know if you have any questions.
