Cloud Foundry – Concepts

Applications are defined as a unit of deployment in Cloud Foundry.

• Cloud Foundry allows developers to focus only on an application (not on services or runtime) by providing PaaS to deploy an application.

• Applications are not limited to a specific language or a runtime environment.

Buildpacks

• Permits Cloud Foundry to support various languages and deployment environments.

Manifests

• Manifests are the deployment blueprint for an application.

• Includes the application details like application name, memory usage, instances, host, and domain.

Organizations are the first administrative unit in Cloud Foundry.

• Contains Spaces and Users.

• Default domain (PCF: cfapps.io) is provided for all organizations.

• Defines quotas and security.

Space is the location where the application is deployed.

• An organization can have multiple spaces. Default space for PWS is development

• Applications and services are scoped to space.

• Provides a set of users access to a shared location.

• Users are the members of an organization. You can invite the users to share your cloud.

• Roles control access to the spaces and domains, and also control those who have permission to manage routes, deploy applications and add/bind/remove services.

Note: You need not be a Cloud Foundry user to access the deployed applications because each application sets up its user management.

Quotas

• Restrict the usage and the availability of resources to the organization, space and web application.

Domain

• A URL to which the deployed applications are associated.

Routes

• Links domain to the actual application.

Services

• Add-ons that can be provided alongside your applications.
