Hi team,

I found the Travis CI already support testing on arm64(https://blog.travis-ci.com/2019-10-07-multi-cpu-architecture-support), but it's still in test-alpha status.

Here I'd like to introduce OpenLab to the community also for the secondary choice. OpenLab is a open source CI system that can test any open source software on either x86 or arm ARCH, it's mainly used by github projects. Now some projects has integrated it already. Such as containerd (a CNCF project), terraform and so on.

OpenLab uses the open source CI software Zuul for CI system. Zuul is used by OpenStack community as well. integrating with OpenLab is quite easy using its github app. All config info is open source as well. It is very similar with Travis CI.

The first question: I just find a single aarch64 packages in page [1], which is just for ubuntu16.04 OS. So I want to know whether community team has a plan to support more? More OS on ARM?

The second question: I cannot find any external CI system in github mongodb/mongo repo. So how community can check the new PR is good? Does it work via internal CI system to run regression tests? Do you accept a external ARM CI system(travis or openlab) if you don't have a ARM CI?

Thanks very much, and wait for your feedback.
