Infrastructure as Code

- Written declaratively (just enough ruby DSL)

- Repeatable

- OS agnostic

- Source control

- Active community (tons of ready to use cookbooks)

Infrastructure as Codeinclude_recipe “java“ package "tomcat6“ artifact_deploy "tomcat6“ do version "latest“ artifact_location "foo.war" deploy_to node[:tomcat][:work_dir] end service "tomcat6" do action [:enable, :start] end

include_recipe “java“ package "tomcat6“ artifact_deploy "tomcat6“ do version "latest“ artifact_location "foo.war" deploy_to node[:tomcat][:work_dir] end service "tomcat6" do action [:enable, :start] end
