Download as PPTX, PDF0 likes545 views
This document discusses the use of Spring Boot to quickly build applications that can consume public cloud services. It emphasizes the advantages of utilizing service brokers to avoid vendor lock-in and provides a comparison of the traditional approach versus using Spring Boot for managing service credentials. Key takeaways include the recommendation to use Spring Boot and service brokers for developing Cloud Foundry applications that interface with Azure and GCP services.

Write code to read VCAP_SERVICES credentials from the environment 2. Add JSON dependencies and parse the VCAP_SERVICES JSON to extract the credential values 3. Add the dependencies for the libraries provided by the service provider for the type of service. 4. Write code to instantiate the appropriate beans. Examples: • com.google.cloud.storage.Storage • com.microsoft.azure.documentdb.DocumentClient 9
