About the MultiCloud API

• RESTful: Resource URLs, HTTP Verbs, Error Codes, …

• Versioned: 1.5+ is our MultiCloud API

• Supports JSON and XML Response Formats• Flexible Authorization: Account (user/pass, OAuth2) or from Instance

(token)

• Simple resource queries through filters• Customer control of detail level through views• MediaTypes support and annotated responses• Extensive documentation, examples, and a Ruby client

A Common Programmatic Interface Across Multiple Clouds

MediaTypes and Annotated Responses• Each Resource has an associated MediaType that

includes:• Attributes• Links (navigation hrefs to related resources)• Actions (possible actions to perform to the specific resource)

• Example response for an instance resource (simplified):Content-Type: application/vnd.rightscale.instance

<instance> <name>name_361342744</name> <state>operational</state> <links> <link rel="self” href="/api/clouds/479517647/instances/ABC2383349127DEF”/> <link rel="deployment” href="/api/deployments/1181”/> <link rel="server_template” href="/api/server_templates/1223”/> </links> <actions> <action rel="terminate"/> <action rel="run_executable"/> </actions></instance>

Example from the RightScale Ops Team

POST /api/tags/by_tag (resource_type=instances,tags=[svc:app=true])

foreach instance_href as i {POST {i}/run_executable

(recipe_name=pull_code) // get 202 & task-id

do GET /…/task/{task-id}until(status == completed)

POST {i}/run_executable (recipe_name=web_restart)}

Get all servers by app tag

For each Server in result

Get new code

Wait for code to download

Restart Web server

•Rolling upgrade of your app servers:
