DevOps and PaaS have been taught as two different and often competing approaches to bring applications to and manage them in the cloud. In this presentation I argue that DevOps tools such as Chef serve as a good foundation for a better PaaS building on DevOps. You can also read my blog post on this subject for more information: http://natishalom.typepad.com/nati_shaloms_blog/2012/01/there-are-currently-two-main-approaches-for-developing-and-managing-application-in-the-cloudpaas-paas-takes-a-developer-ap.html

1. Bringing PaaS & DevOps Together

2. Perspectives on PaaS
Developer: “PaaS is so Sys admin: “PaaS is just
easy, who needs sys giant blackbox toy that I
admins anyway”? can’t really use for real-
world app”

3. Perspective on DevOps
 DevOps is all about:
 Automating complex IT
processes
 With Full visibility and
control

4. PaaS & Devops can be complementary
PaaS DevOps
 Application life cycle &  Infrastructure management
orchestration (OS setup, network, security
(deployment, fail-over, auto configuration)
scaling)  Application installation
 Application service (package, configure, install)
dependencies (web->
database)
 Integrated application
Management & Monitoring  Ops centric
 Developer centric

5. Bringing PaaS & DevOps together
 DevOps would make a good foundation for PaaS…
 Best of both worlds
 High productivity (PaaS) without loosing control (DevOps).
 Integrates Devops concepts into PaaS
 Use DSL to describe PaaS applications packages
 Calls your own scripts (batch, shell,..)
 Integrated with existing DevOps tools
 Aautomate the setup of a chef configuration environment
 Leverage Chef built-in cook books and installation scripts
