My Cloud Story – The Beginning● Building virtualization stacks and rudementary “clouds”
- Xen, Kvm, iSCSI, DRBD, Pacemaker, etc. ●Glue, Glue, Glue. Duct Tape, Duct Tape, Duct Tape.
- The basics were there, but the management capabilites were not.● Proprietary offerings were better but $$$ was an issue.● Open Source solutions worked but still a bit clunky● My Goals: Lowering costs, not so much accelerating productivity

My Cloud Story – The Amazon Days● Working Operations at a Software-as-a-service startup● True Infrastructure-as-a-Service● APIs to meet our needs● Traded performance for amazing flexibility● automation == foozball (read: Beer)● Introduction to Ubuntu Server (the defacto on EC2)● Something seems off...

My Cloud Story – The Open Cloud● Safe to assume Amazon leverages FOSS ● Lets build a platform that suites the needs of all its users● Allow and encourage community and growth● We have the tools and we know how to use them: OS, software, community.

Juju?
Service Orchestration Framework
● Originally intended for the cloud (EC2):
$ juju deploy cs:wordpress
$ juju add-relation wordpress haproxy
$ juju add-unit wordpress
● It would be useful to expand to other providers:
$ juju deploy -e hpcloud cs:hadoop-slave$ juju add-relation hadoop-slave hadoop-master$ juju add-unit -n 10 hadoop-slave
● Also became apparent the same has value on HW:
$ juju deploy -e MAAS cs:nova-compute$ juju add-relation nova-compute nova-cloud-controller$ juju add-unit -n 5 nova-compute
13
How do we do it?
● Problem 1: Cloud inter-operability● EC2, HP, Azure, etc., etc.
● Problem 2: Hardware● Hyper-scale?
We have the tools and we know to use them.

● API-driven machine provisioning● Consumable by Juju as a baremetal provider● Dynamic, flexible and “cloudy”
● Designed to scale● OpenStack● Hadoop● Cloudfoundry

● Flexible, First boot configuration system● Yaml format● Install packages, import SSH Keys, run arbitrary
scripts, etc.● Integrated with system init.
● Provider agnostic● Plugable data sources● EC2, OpenStack (config drive), KVM, local
● Easily extended● Many user-contributed extensions and data
sources.
● Integrated● Baked into Ubuntu Cloud Images.● Used heavily by MAAS and Juju

Example cloud-init
#cloud-configpackages: - git - bzr - python-setuptools - python-pip - vim - tmux - ipython
apt_mirror: http://mirror.home.base/ubuntu/
runcmd: - [ wget, "http://amebix.home.base/~adam/devenv/vimrc", -O, /home/ubuntu/.vimrc ] - [ wget, "http://amebix.home.base/~adam/devenv/bash_aliases", -O, /home/ubuntu/.bash_aliases ] - [ wget, "http://amebix.home.base/~adam/devenv/gitconfig", -O, /home/ubuntu/.gitconfig ] - [ wget, "http://amebix.home.base/~adam/devenv/gdbinit", -O, /home/ubuntu/.gdbinit ]

Example cloud-init
#cloud-config# Mounts volfile exported by glusterfsd running on# "volfile-server-hostname" onto the local mount point '/mnt/data'#packages: - glusterfs-client
mounts: - [ 'volfile-server-hostname:6996', /mnt/data, glusterfs, "defaults,nobootwait", "0", "2" ]
runcmd: - [ modprobe, fuse ] - [ mkdir, '-p', /mnt/data ] - [ mount, '-a' ]

● MAAS can deploy any workload Juju can deploy.
● Hadoop on EC2● Hadoop on Metal
● MAAS is but one of many Juju providers.
● EC2, Openstack, Azure, LXC
● Cloud Images and cloud-init environment agnostic.
● Cloud-config on hardware● Ubuntu Cloud Image in LXC

Unifying the Experience
● On EC2:$ juju deploy -e EC2 cs:wordpress$ juju add-relation wordpress haproxy$ juju add-unit wordpress
● On baremetal:$ juju deploy -e MAAS cs:nova-compute$ juju add-relation nova-compute nova-cloud-controller$ juju add-unit -n 5 nova-compute
● On HP Cloud:$ juju deploy -e hpcloud cs:hadoop-slave$ juju add-relation hadoop-slave hadoop-master$ juju add-unit -n 10 hadoop-slave
● On your private cloud:$ juju deploy -e openstack cs:mediawiki$ juju add-relation mediawiki mysql

My Own Use Case
OpenStack Integration Testing

My Own Use Case
OpenStack Integration Testing
● Using Juju and MAAS, deploy full OpenStack cloud to bare-metal
● Run integration and smoke tests against deployed cloud
● Use Juju to deploy an application into the new cloud, native OS API
● Use Juju to deploy an application into the new cloud, native EC2 API
