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

Performance
