A simple-to-deploy (and manage)
cloud catalyst.

13. Deltacloud
To be cloud-agnostic, CoolingTower uses
Deltacloud to interface with providers.

16. Bootstrap your PaaS
CoolingTower is a simple Ruby-on-Rails
application you deploy in JBoss.

19. Role #1
“I want my app running”

22. Remember!
Besides CoolingTower and the
Deltacloud adapter, there is no AS
or anything running... yet.

24. Cold start!

26. Your app is now deployed.

27. What just happened?

28. CirrAS
CoolingTower just used Deltacloud to
launch a JBoss AS cluster, plus a front-
end tier of mod_cluster.
These are CirrAS appliances.

29. First, send out a scout...
• Launch a management node, the spine
upon which the PaaS rests.
• Cluster-specific configuration passed to
management node.
• AWS credentials
• S3 bucket for clustering
• Coordinates the weaving of all other nodes.
• Includes RHQ/JON/JOPR.

30. IaaS Provider
CoolingTower Deltacloud
Management
localhost

31. Then launch the tiers...
•Launch 1 node of EWS
• mod_cluster
• Apache httpd
•Launch 1 node of EAP
• JBossAS

32. IaaS Provider
EWS
CoolingTower Deltacloud
Management
localhost
EAP

33. Management Node, activate!
Management node watches the
IaaS, notices new nodes appearing.

34. Cluster Configuration
• Tells each EAP node about each
EWS node
• Tells EAP nodes about the S3 bucket
for clustering.
• Restarts services on nodes as
appropriate.

35. IaaS Provider
EWS
CoolingTower Deltacloud
Management
localhost
EAP

36. Cluster Formation
•EAP nodes rendezvous on S3 for
cluster discovery.
•EAP node informs EWS nodes of
cluster view.

37. IaaS Provider
EWS
CoolingTower Deltacloud
Management
localhost
EAP S3

38. There ya go...
From nothing to minimal 2-tier
cluster in 1 click.
but that’s not all!

39. Your app gets deployed
CoolingTower wakes up, notices an EAP
node is ready, and deploys your app.

40. IaaS Provider
EWS
CoolingTower Deltacloud
Management
localhost
EAP S3

41. Gives you a URL

42. mod_cluster status

43. Role #2
“I gotta keep all of
this stuff running”

44. PaaS Administrator
Ultimately a PaaS is a shared
resource. One administrator
for N applications.

50. Scale
To scale a tier, administrator simply
launches more nodes.
CirrAS appliances have been intentionally
designed to be automatically horizonally
scalable.

51. *c lic k*

53. I love coffee.
Now would be a good time
to enjoy some.

54. What’s going on?
While we enjoy our beverage...
• Another CirrAS node starts up.
• Management node notices.
• Shoots configuration (S3, EWS) to it.
• It joins the cluster.
• Neighbor hands the app to it.
• It becomes an available worker.

56. Oh yeah, JON

58. Embedded JOPR

59. Role #3
“I’m a user, and I want to
use your app a whole lot.”

60. Our user...

64. Take a node
out of service.

66. Scale more!

68. For less than the cost
of a cup of coffee...
1 EWS $0.08
5 EAP $0.40
1 Management $0.08
$0.56

69. Roadmap
• Application versions
• Multiple clusters/environments
• Per-application configuration
• ELB/HAProxy support

70. Thanks!
