The Kotlin version of the same application is here.https://github.com/papicella/Kotlin-PivotalSpringBootJPA
Kotlin is a functional language developed by the JetBrains guys. Its main benefits are:
- Conciseness of code
- Code safety - Null (more...)
Apigee and Pivotal partnered to provide comprehensive API management capabilities that expedite the scalable delivery of apps on the powerful Pivotal Cloud Foundry platform. Apigee Edge is available for rapid deployment as a partner service in the Pivotal Network
The following link talks about this service in detailhttp://apigee.com/about/solutions/pivotal-cloud-foundry-apigee
