PCF stands for Pivotal Cloud Foundry which is an opensource Platform-as-a-service (PaaS) for many orchestrated polyglot applications in public or private environments. Polyglot suggests that we will work with completely different environments like, Java, .Net, Python etc. PCF is orchestrated so we will login and monitor the applications.
