Technically, Acquia Cloud uses Percona 5.5, and not MySQL. While they are practically compatible, SQL-wise, there are performance and minor technical differences which make it worth switching.

I currently don't have a Percona role on Galaxy, but it should be relatively simple to set things up—Percona uses a similar configuration layout as MySQL, and they have an official yum repo and apt repo, so installation wouldn't be too bad.

I just created a new version of the geerlingguy/ubuntu1204 box for the vmware provider. I'd like to use it and then benchmark how it performs against virtualbox for a large Drupal site.

See title. XHProf is incredibly helpful for profiling PHP code (especially for bulky and/or long-lived operations). A nice tool to have available.

See: http://www.drupalvm.com/

My plan is to make Drupal VM be flexible enough to emulate most traditional cloud providers and configurations, by allowing users to specify versions of PHP, Apache, MySQL, etc., and allow easy switching between different standardized base boxes (e.g. Ubuntu 12.04 or 14.04, CentOS 6 or 7).

Most of my roles are already able to do this kind of switching, but a few are not. I'll need to see how much more effort is required.

Additionally, I'd like to get geerlingguy/drupal-vm#33 resolved (easy multisite/multi deployment setup) prior to deprecating this VM.

Either Solr + Tomcat (like with geerlingguy.tomcat6 + geerlingguy.solr, or with tomcat7), or Solr + Jetty. It would be nice to be able to work on search in the same VM, without having to spin up another or use a live cloud instance.

One of the two tools would be nice to help debug email sending inside the VM... and to prevent the VM from accidentally sending out emails to the outside world.

It seems I've forgotten to get this working. D'oh!

For now, if you need it to be installed, after all provisioning is complete, run the following two commands:

# printf "\n" | pecl install apc
# service apache2 restart

It shouldn't be too difficult to provision the full Acquia Cloud stack locally, either using a bunch of VMs, or using one VM with a bunch of Docker containers...

It seems the infra is something like:

varnish (reverse proxy, port 80) / nginx (load balancer, port 443)
                                   /   \
                apache/php/memcached | apache/php/memcached (application)
                                   \   /
                              mysql (actually, Percona)

Also, uses Gluster for shared filesystem access.
