DecomposableservicedefinitionModular/adaptablearchitecture
• NGPaaSisabletobuildcustomizedPaaSs:• By abstracting components of the
PaaS (e.g. the SDNC) into ReusableFunctionalBlocks(RFBs).
• RFBs are then used by an editor tocompose platform and servicegraphs.

VIMAdaptationLayerforCORD:ProblemStatement
13 12/18/18
• CORD4.Xbuildingblocks(XOS,OpenStackandONOS)aretightlyintegratedandcannot
beeasilyreplacedorextendedwithsimilartechnologies
• E.g.KubernetesinsteadofOpenStack
• E.g.OpenDaylightinsteadofONOS
• ThistightintegrationcanactasabarriertotheuseofCORD.

VIMAdaptationLayerforCORD:Proposal
14 12/18/18
• IdentifytheinteractionsbetweenXOSandOpenStack/ONOS
• Based on the identified interactions, define a generic interface that allows CORD to
supportmultipleVIMs.
• Users/AdministratorsofaCORDPODbecomeagnostictotheunderlyingVIMs.
