1. Nuxeo on the Cloud
Stefane Fermigier (Nuxeo), Nick Barcet (Canonical) - 2011/10/21
Open Source ECM

2. What’s the Cloud?
2

3. Cloud Services
Applications
Application containers
Virtual machines
and storage
3

4. Scale As You Need
• Manual or Automatic provisioning
• The Cloud knows what’s available
4

5. Pay As You Go
• Instances (Memory, CPU)
• Storage
• Bandwidth
• Applications
5

6. Public / Private / Hybrid
• Public commercial cloud
• Private instances
• Needs the full cloud machinery locally
• Hybrid model
6

7. Why Nuxeo on the Cloud?
7

8. Use Cases and Business
Motivations
• Developers
• Business Users
• Ops
8

9. Nuxeo Cloud for Developers
• Quick setup of development instances
• Rapid deployment from Nuxeo Studio
and Nuxeo IDE
9

10. Nuxeo Cloud for Business
• Quick setup of business applications
• Customize using profiles from the Nuxeo
Marketplace in the Update Center
10

11. Nuxeo Cloud for Ops
• Simplify and speed up Nuxeo
deployment on public or private clouds
(e.g. OpenStack)
• Manage your instances
11

12. Current State
of Nuxeo Cloud
12

13. Nuxeo as SaaS
• Running on Amazon EC2
• Managed Nuxeo instances
• Customizable through Nuxeo Studio
• Arbitrary plugins allowed
13

14. Nuxeo as SaaS
14

15. Nuxeo on IaaS
• CloudFormation scripts (Amazon)
• Or pre-baked images (AMI)
15

16. 16

17. Upcoming Offers
17

18. Nuxeo on IaaS
• Short term projects
• Upcoming support for more IaaS providers (ex:
Rackspace) and private IaaS (ex: OpenStack)
18

19. Nuxeo on a PaaS
• Short / medium term projects
• Options: Elastic Beanstalk, CloudBees, Cloud
Foundry, OpenShift...
• All need customization due to our own specific needs
• CloudFoundry is currently the only open source solution
• Need an open source platform to adapt it to our own
needs (Studio, Update Center...)
• Cloud Foundry (maybe)
• OpenShift when they decide to open it for real 19

20. Focus on CloudFoundry
• Set of command-line tools to deploy applications
(Java, Ruby, Node...) to a public PaaS (owned by
VMWare) or your own
• Takes care of application provisioning, starting,
stopping, monitoring
• Can add / remove instances to scale up / down
your applications
20

21. Nuxeo on CloudFoundry
• One needs to patch several pieces of
CloudFoundry
• Sample Usage:
$ vmc push myapp --no-start
$ vmc start myapp
$ vmc apps
+-------------+----+---------+----------------+------------------+
| Application | # | Health | URLS | Services |
+-------------+----+---------+----------------+------------------+
| myapp | 1 | RUNNING | myapp.vcap.me | myappdb |
+-------------+----+---------+----------------+------------------+
21

22. Current issues
• We still need to figure out how to support some
important Nuxeo features on this platform:
• Hot deploy / reload
• Updates through Nuxeo Connect
22

23. Scale up
$ vmc instances myapp +1
$ vmc instances myapp
+-------+----------+--------------------+
| Index | State | Start Time |
+-------+----------+--------------------+
| 0 | RUNNING | 09/30/2011 05:20PM |
| 1 | RUNNING | 09/30/2011 05:24PM |
+-------+----------+--------------------+

24. Nuxeo as a PaaS
• Longer term
• Multi-tenant PaaS specific to ECM applications
• ECM as a service

26. DevOps, Distilled

27. What is DevOps?
 Rate of agile development and deployment requires deeper
interaction between teams
 A melding of development, deployment, and QA principles,
methods, and practices
 Fills the gap between developers and system
administrators
Presentation by Nick Barcet

28. What drives DevOps?
 Speed of the deployment
 Continuous Integration, Automated Testing, etc.
 Fast change vs. Stability
Presentation by Nick Barcet

29. What does DevOps “deliver”?
 Fast repeatable server setup, consistent environment
 Abstract ops tasks to empower devs
 Smaller deployments empower ops
 Repeatable processes that let you scale out quickly
Presentation by Nick Barcet

30. You've got the tools already
 Hardware
 Virtualization
 Platform (OS)
 Configuration Management
need to tie that together into something whole.

33. Juju, DevOps Distilled
Dev Ops
 Reuse existing deployment charms in an Explicit control over deployment,
openly-accessible repository of shared configuration and upgrade options
expertise See what’s deployed and track usage in the
 Reproduce deployments for test and cloud
staging purposes
Create and share charms for new
 Rapid deployment of your dependencies applications
for development purposes
Monitor, scale, shrink and adjust
 Compose whole systems from individual deployment parameters in real time
application components and describe the
Explicitly connect different components and
entire deployment
maintain those relationships over time
Collaborate with developers on the exact
deployment and upgrade processes
Get more done: implement decisions
immediately regardless of infrastructure

34. Juju's Charms
 Charms are a shareable, re-usable, and repeatable
expressions of DevOps best practices.
 You can use them unmodified, or easily change and
connect them to fit your needs.
 Deploying a formula is similar to installing a package on
Ubuntu: ask for it and it’s there, remove it and it’s
completely gone.
Presentation by Nick Barcet

35. Juju is a community of DevOps expertise.
 Most of the application you want will be available in Juju.
 Juju provides direct and free access to a DevOps
community-contributed collection of formulas
Presentation by Nick Barcet

36. Juju provides service orchestration
 Juju focuses on managing the service units you need to
deliver a single solution, above simply configuring the
machines or cloud instances needed to run them.
 Charms developed, tested, and deployed on your own
hardware will operate the same in an EC2 API compatible
cloud, including OpenStack.
Presentation by Nick Barcet

37. Juju is intelligent
 Juju exposes re-usable service units and well-defined
interfaces that allow you to quickly and organically adjust
and scale solutions without repeating yourself.
Presentation by Nick Barcet

38. Juju is Easy
 There’s no need to learn a domain specific language (DSL)
to use Juju or create formulas. You can be up and running
with your own formula in minutes

51. Nuxeo on Juju
47

52. Use case
• We already know how to deploy single server
instances of Nuxeo on the cloud (ex: using
CloudFormation)
• But deploying fault-tolerant and scalable multi-
servers instances is still a manual process
• Enters Juju...
48

53. Target architecture
49

54. Bootstrap the environment
$ juju bootstrap
# Wait a couple of minutes
$ juju status
..
50

55. Launch the services
$ juju deploy --repository=charms
local:haproxy
$ juju deploy --repository=charms
local:nuxeo
$ juju deploy --repository=charms
local:postgres-nuxeo
51

56. 52

57. Connect the services together
$ juju add-relation haproxy:reverseproxy
nuxeo:website
$ juju add-relation postgres-nuxeo:db
nuxeo:db
53

58. 54

59. Open the business!
$ juju expose haproxy
55

60. Users are coming !
56

61. Add more servers!
$ juju add-unit nuxeo
$ juju add-unit nuxeo
57

62. 58

63. Additional goodies
• NFS storage (or S3 / S3-like)
• Monitoring
• Auto-scalability (add more Nuxeo servers when
loads increases, remove them afterwards)
• HA and scale out for the PostgreSQL, for HAProxy
• Backups
• Integration with Nuxeo Connect & Nuxeo
Marketplace 59

64. Work in progress
• Juju is still a developer preview (will reach
production-readiness in April 2012)
• Watch (and contribute to) our charms on
