Cloud Foundry component glossary
Page last updated:
This topic tells you about Cloud Foundry terms and definitions.
| Term | Definition |
|---|---|
| API | Application Programming Interface |
| Availability Zone (AZ) | An independent network infrastructure segment used to increase availability and fault tolerance. An AZ is often correlated with a geographical region. A cloud operator can select or assign AZs on platforms such as AWS and vSphere. |
| BOSH | An open framework for managing the full development and deployment life cycle of large-scale distributed software applications. |
| CLI | Command Line Interface |
| Domains | A domain name like shared-domain.example.com. Domains can also be multi level and contain sub-domains like the “myapp” in myapp.shared-domain.example.com. Domain objects belong to an org and are not directly bound to apps. |
| Droplet | An archive within Cloud Foundry that contains the app ready to run on Diego. A droplet is the result of the application staging process. |
| Managed Services | Services provided by third parties that are integrated into Cloud Foundry through APIs so that Cloud Foundry users can provision reserved resources and credentials on demand. Also called Custom Services. |
| Management | You can manage spaces and orgs with the Cloud Foundry Command Line Interface (cf CLI), the Cloud Controller API (CAPI), and the Cloud Foundry Eclipse Plug-in. |
| Org | An org is the top-most meta object within the Cloud Foundry infrastructure. Only an account with administrative privileges on a Cloud Foundry instance can manage its orgs. |
| Routes | A route, based on a domain with an optional host as a prefix, can be associated with one or more apps. For example, myapp is the host and shared-domain.example.com is the domain when using the route myapp.shared-domain.example.com. You can have a route that represents shared-domain.example.com without a host. Routes are children of domains and are directly bound to apps. |
| Service | A “factory” which produces service instances. |
| Service Instance | A reserved resource provisioned by a service. The provisioned resource differs by service. For example, the resource might be a database or an account on a multi tenant app. |
| Spaces | An org can contain multiple spaces. You can map a domain to multiple spaces, but you can map a route to only one space. |
| Staging | The process in Cloud Foundry by which the raw bits of an application are transformed into a droplet that is ready to be run. |
| UAA | User Account and Authentication Service, which provides the technological basis for Dashboard Single Sign-On. This is available to Cloud Foundry users when accessing pertinent Managed Services. |
| Warden | The mechanism for containerization on Diego that makes sure apps that are running on Cloud Foundry have a fair share of computing resources and cannot access either the system code or other apps running on Diego. |
