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
