43 @saturnism @gcpcloud Pivotal Cloud Foundry Support Native - Google and Pivotal engineers built support for PCF on GCP. Use things like global load balancing and pre-emptible VMs to scale applications or reduce cost. Integrated - The GCP Service Broker lets developers provision and use Google services in their apps without manually creating and managing resources in the console. Observable - Stackdriver debugging, monitoring, and logging make it easy to observe your Spring applications deployed to PCF on GCP.
