How Cloudify uses Chef as a foundation for PaaS

PaaS

IaaS

PaaS

IaaS

The Blurring line between IaaS & PaaS


IaaS, PaaS & Apps

• IaaS & PaaS run on Software just like any App– Messaging: RabitMQ– DataBase: Postgress– Web Container

• Common needs– Automation– HA– Scaling ..


IaaS delivers software services

• IaaS Services– RDS, – SimpleDB – LoadBalancer – Memcache


PaaS delivers Software Services


But..

• Services are delivered as a black-box• We have little control over the type, version or

the way those services are delivered• Inconsistent behavior & management

– IaaS & PaaS run on separate deployment, scaling, HA and Scaling models


Apps are a composite of services

Apps is a living organism – Things can fail, move, be added over time


Welcome to the Open Cloud

– New opportunities on how to deliver IaaS & PaaS:• Share infrastructure between the two layers• Gain better control on the way services and apps are

being delivered


Enter Chef

• Why Chef? – Setup and Configure software services– As a foundation for IaaS – 100’s of cookbooks – Open Source

• It only makes sense to use Chef as a foundation for PaaS

Chef & Cloudify

Cloudify• App life cycle &

orchestration (deployment dependencies, fail-over, auto-scaling)

• Application management & Monitoring

App-Centric

Chef• Infrastructure management

(OS setup, network, security configuration)

• Setup & installation (package, configure, install, start)

Infrastructure-Centric

• Integration anatomy (how things happen) • Working With Chef Client

– Configuring the Chef Server information in Cloudify– Preparing a Recipe that wraps a cookbook– Running the recipe

• Working With Chef Solo– Preparing the recipe– Installing chef server using chef solo

• Updating the Chef Server• Interacting with Chef after deployment

• Extend the base Chef Recipe to Install the run list you need

Create The Recipe

service { extend "../../../services/chef" name "your service name" type "DATABASE" numInstances 1

compute { template "SMALL_UBUNTU" } lifecycle { startDetectionTimeoutSecs 240 startDetection { ServiceUtils.isPortOccupied(System.getenv()["CLOUDIFY_AGENT_ENV_PRIVATE_IP"], 3306) } }

}

Custom Service Name

Add Custom Start Detector

Extending the Chef Recipe

• Have the following in your recipe properties file:

18

Configure The Recipe

runParams = [“param1": “value1”,“param2": [“key1”:”subvalue1”,…]…"run_list": ["recipe[cookbook_name::recipe_name]"]]

Runtime parameters

Run list(Recipes or Roles)
