Service Brokers

  • What is a service broker?

    A component of the service which implements the service broker API. This component advertise a catalog of service offerings and service plans, as well as interpreting calls for provision (create), bind, unbind, and deprovision (delete).

  • Why do we need service brokers?

    To make the service available in marketplace for the apps running in CloudFoundry.

  • How do a service broker and the Cloud Controller intercooperate?

    The basic auth username and password which are provided when adding a broker are encrypted in Cloud Controller database, and used by the Cloud Controller to authenticate with the broker when making all API calls.

  • What is the purpose of each broker endpoint?

    • Catalog Endpoint - makes the plans in the service available for users.
    • Auth Endpoint - enables Cloud Controller to authenticate the service broker with Username and password.

  • In general terms, how would you write your own service broker? How would you test it? How would you deploy it for everyone else to use?

    • Create a service broker.
    • Register the service broker.
    • Make the plans publicly available in the catalog.

pluralsight recap

  • Where does a service broker have to be deployed?

It just needs to be deployed somewhere that the cloud controller can reach it via an HTTPS call. It can live inside PCF as an application or outside of it

  • Why provide unique credentials per binding?

It's the recommended best pratice so that unbinding doesn't affect other applications other than the application being unbound

  • Can service broker support an upgrade or downgrade of a service?

Upgrade support

  • The borker is required by the cloud controller to respond within how many seconds?

60 seconds

  • Does provisioning have to be done synchronously?

No, it can be done asynchronously if you have a really long provisioning times. There's another endpoint to be implemented.

  • Do all services have to be bindable?

No, they don't
