a. Describe key components of IBM Bluemix PaaS environment
1. Runtime is a set of resources to run an application. Bluemix provides runtime environments as containers for different types of applications. The runtime environments are integrated as buildpacks into Bluemix, are automatically configured for use, and require little to no maintenance.
2. Boilerplate consists of a combination of runtime and predefined services. Because they contain a runtime and set of services for a particular solution type, they can be used to quickly get an application up and running.
3. Services provide ready-for-use functionality for a running application and are represented by two types:
a. Managed services are listed in the IBM Bluemix PaaS catalog. A Managed Service integrates with Bluemix/Cloud Foundry via a service broker that implements the Service Broker API. The service broker advertises a catalog of service offerings and service plans to Bluemix/Cloud Foundry and receives calls from Cloud Foundry for four functions: create, delete, bind, and unbind.
b. User-provided services can be used by developers to programmatically define services outside of IBM Bluemix PaaS. This gives a mechanism to provide credentials to applications for service instances which have been pre-provisioned outside of Bluemix/Cloud Foundry.
