Integration(Networking)
• Bluemix Public• Partofthepublicinternet• Internetworkingwithon-prem:
1. UseServiceGatewayand/orVPNOR2. ExposeAPIsfromexistingon-premise
• Bluemix Dedicated• Bydefault,networkispartofcustomer’snetwork• Canbeopenedtopublicinternetalso
• Bluemix Local• Alwaysnetworkedtobepartofcustomer’sinfrastructure
Integration(Functional)
• APIConnectforGreenfield
• IIBisalsoanoption:
Security
• Bluemix Public• MakeeverythingrunoverHTTPS• AllCFruntimes areexposedpublically;Docker(inparticularwithKubernetes)willprovidemorecapability
• Thinkaboutdataresidency– CFservices canbeprovisionedanywhere
• Bluemix Dedicated• Dataresides outside yourdatacenter
• Bluemix Local• Dataresides locallyas longasyouusealocalservice• Ifyouuseafederatedservice, youareusingPublic
