Did you know that BOSH is not the only tool for deploying the Cloud Foundry PaaS?.. Initially presented at the 2014 DevOps Summit by Andrei Yurkevich, CTO @ Altoros, this slide deck demonstrates how to deploy CF with Juju Charms and compares this orchestration solution to BOSH. It also covers overlapping features and explains when to use BOSH, Juju Charms, or both. For more Cloud Foundry research, visit: http://www.altoros.com/research-papers

How can you do it in your case?
● Rapid provisioning of dev
environment
● High availability
● Security and governance
● Authorization and access
management
● and...

10. @yurkvch | @altoros
And more!
● No IaaS vendor lock-in
● Self-healing
● Scalability
● Zero downtime upgrades
● Portability
● Minimal human involvement

Who else can do the job?
Puppet Chef Salt Ansible Juju Bosh
Deployment lifecycle management Rolling Updates
Monitor / Health Checking
Backup and Restore
Orchestration Networking
Storage Management
VM Provisioning
Life-cycle Management
Interdependence (ability to create relations between services
without restarting deployment process)
Service Discovery Only in Enterprise With Plugin
Configuration Packaging
Templating
Service provisioning

20. @yurkvch | @altoros
Manual installation?
o Experience in creating and
deploying services
o Deep understanding of
virtualized cloud
infrastructure
o DevOps skills for many
platforms
o Knowledge of Cloud Foundry
internals
o CF is configured manually
o Human factor
o No self-healing

Why do we need one more tool?!
BOSH:
● incredibly complicated
● limited talent availability
● no software defined networking
● limited ecosystem (data services)

● A complete stack by Canonical:
o Hardware: MAAS
o IaaS: OpenStack is deployed on
MAAS with Juju
o PaaS: Cloud Foundry is deployed atop
OpenStack using Juju
● GUI allows for designing, building,
configuring, deploying, and managing an
infrastructure
● Charm Store with hundreds of charms
● An easy switch between target
environments
Let’s do it!

32. @yurkvch | @altoros
Issues and limitations
● Juju local environment is not supported
● CF version is r180
● Limited number of service brokers

33. @yurkvch | @altoros
Current state of the project
● core CF functionality
● charms generator for new version of cf-release
● using templates from cf-release
● possibility to set placement strategy
● deployment to AWS and OpenStack
● uses pre-built packages from S3

34. @yurkvch | @altoros
Look into the future
● no “rolling updates”
● lagging support of new versions of CF
● CF juju charms use non-trivial approach to deployment:
○ default way: charm are deployed one by one and relation
are added after it.
○ cf charm way: one (orchestrator) charm is deployed and
then it manages installations of other charms. CF charm
has limited types of configurations.
