• AirVantage production is deployed in
two datacenters: France and Canada
• Our preproductions are hosted in our
Toulouse facilities
• Pure collocation mode (we purchase
our hardware and deploy in
« empty » racks).
• Virtual and physical machines (for
perfomances, appliances – HSM,
RSA, VPN concentrator)

Our Infrastructure in 2010
• Complex deployments: multiple Java webapps, multiple stores: Oracle,
Solr, Hadoop, Redis, message queue, etc.
• Deployed in multiple environments (pre-productions, two productions)
• Eavy usage of virtual machines (service isolation). Virtual Machines
built « by hand »
• Lot of copy-paste from wiki pages

AirVantage Private Cloud Management
• AirVantage M2M Cloud is deployed in an
OpenStack private cloud
• OpenStack is a open source project initiated by
NASA and Rackspace.
• Sierra Wireless Team manages hardware,
virtualization layer and cloud software to
optimize performances and security.
• Machines (physical or virtual), and services are
automatically configured using Puppet
configuration management tool.
• Puppet configurations are historized and
validated like software changes.
Puppet is also used by
Wikimedia Foundation,
Dell, Rackspace, Twitter,
Disney, Oracle and
Google, among others.
OpenStack is also used by
NASA, Rackspace Cloud,
HP Public Cloud, AT&T,
Deutsche Telekom,
Wikimedia Labs, among
others.

Why OpenStack?
• Open Source Private Cloud infrastructure support
• Well known components in our infrastructure team:
– Ubuntu Linux
– Libvirt/kvm
– Bridge/VLAN in Linux
• OpenStack is only a “glue” between existing and robust
components, orchestrating machines lifecycle.
• Pushed by Ubuntu as Private Cloud solution
• OpenStack community: RackSpace, Dell, HP, Canonical, etc.

Our OpenStack History
• Started with Cactus and Diablo on Ubuntu 10.04 in 2010
• First deployment in production based on Diablo + Ubuntu 10.04 in 2011
• Lot of room of improvements, issues identified during the first year (not
all relative to OpenStack)
• Refresh our deployment in 2012 with Linagora assistance
• 2012 deployment: Ubuntu 12.04 + OpenStack Essex (2012.1)

Why not VMWare?
• Open Source culture at Sierra Wireless AirVantage
• The aggressive pricing 
• Capability to use API to manage the infrastructure
• Adopt the “Infrastructure as a Code” movement
• Infrastructure creation scripts are store under version control

Infrastructure status in 2014
• 500+ servers managed on three physical sites administered by a
three engineers team
• Ubuntu 12.04 (Precise)
• OpenStack 2012.1 (Essex) with compute and image registry
• puppet (home made recipes)
• Full stack deployment is now about 2h. We are working to reduce it.
• Automated life-cycle (puppet, cloud-init, unattended-upgrades) of
servers

Lessons learned

• Need time to learn/understand
OpenStack
• Powerful but complex: complexity is not
really hidden
• Some bugs, but rather stable when setup

• Good project documentation
• Very responsive and visible community
• Lot of events around OpenStack (even in
France!)

13. 13Proprietary and Confidential
Conclusion
• Infrastructure As A Code!
• Infrastructure is self-documented
• Industrialization of existing infrastructure
• Infrastructure reproducibility
• More standard tools (instead of home-made tools).
• Deployable on public cloud “as-is”
