  1. NREN viewtowards SDN-enabledservicesandCloud-Federations Peter Kaufmann/DFN FIA, Athens, 19th March 2014

  2. Currentsituation Bandwidthisavailable • Large+flexiblebandwidthcapacities due totransmissiontechnology: flexible ROADMs, coloredinterfaces, ... • Further developments/testbedstowards Tb-technology Services • IP-service, VariousVPN-services (Lambdas, Ethernet, IP, MPLS, ...) • New generationof ROADMs increasestheflexibilityandresponse time for high capacity VPNs BUT • VPNs areconfiguredfrom NREN/Network providers. • Users are „passive“ customersofthe VPN-environment FIA, Athens, 19th March 2014, P. Kaufmann/DFN

  3. SDN Key Aspectseenfrom NREN • SDN (virtual Networks) offerthepossibilityforbettermanagementof VPN • New comfortablemethodto handle the CP NEW possibilityforuseraccesstothe CP, but ... • Even withcomfortableUserAccestotheControlPlane • onlyapplicableforadvancedusers • not forthecommoditycustomers! • Thus: Handling of SDN atuserlevelshouldnot be a prerequisitforfurthergeneralservices(e.g. clouds) FIA, Athens, 19th March 2014, P. Kaufmann/DFN

  4. Cloud-Federations (1) Assumptions • Growingdemandwithin NRENs, interferenceof private andacademic (business) communication, usageof same/similar HW. • (Big) commercialclouds (Google, Amazon etc.) havenointerestforinderdomain/federationapproach. Whyshouldthey? • Commercial power ofcompanycloudsisbig.No/fewchancesforgeneral NREN(Community)-Clouds. FIA, Athens, 19th March 2014, P. Kaufmann/DFN

  5. Cloud-Federations (2) Conclusionfor NRENs • „Reseller“ of „public“ clouds (some NREN do so or will do), Enrichthepubliccloudswithspecialoffers/services • Orlookingfornichesfor NREN (Community)-Clouds • Special functionality • Betterperformance • Bettersecurity/privacy FIA, Athens, 19th March 2014, P. Kaufmann/DFN

  6. Cloud-Federations (3) Security, Privacy, Trust • NSA-Topic: Unclearthe medium/longtermconsequences. Behaviour&requirementsofusersishardtoestimate. • But certainlyforbuisness: Growingrequirementsfor European-basedcompanies&rules (non-US regulation/control) • In Germany: Somediscussionabout Germany-basedsecuritynetworking (due to US-NSA & British-QCHQ) • Security/privacyissuescouldincreasetheneeds (apart from • otherreasons) andthechancesfor NREN-clouds (Federationof NREN-Clouds) FIA, Athens, 19th March 2014, P. Kaufmann/DFN

  7. Cloud-Federations (4) • Federationsof NREN-Cloudscouldenlargethentl. nicheif • Easy touse (e.g. One-StopShopping) • Seamlessservice (self-service), not worsethanpublicclouds • Additional benefits (comparedtosingle NREN-Clouds) • Broadcoverage (likeEduRoam, a successstory) • Open issue: Do Cloud-Federationsoverweighttheunavoidable (technical, admin) overhead? • Wehave not yet real usecases! Chicken-and-Egg problem. => But: „Taste andtrybeforeyou die“ FIA, Athens, 19th March 2014, P. Kaufmann/DFN

  8. SDN & Cloud-Federations (1) • SDN andClouds(and NFV) are (nearly) indpendentissues! • SDN: More importantfornetworkprovidersto manage Networks & Clouds (andforadvancedusers) • NFV: Tofacilitatetheprovisionoffunctionalityforusersby networkproviders • NREN-Clouds (withfederations): Users organizetheir „scientificlife“. • CombinationofSDN&Cloudsoffersthepossibilityof „self-defined“ cloudswithinthe NREN-Federationenvironmentforadvancedusers, but tomuchcomplexityatcommodityuserlevel • => At User Level: Combinationis a nicheinsidetheniche? FIA, Athens, 19th March 2014, P. Kaufmann/DFN

  9. SDN & Cloud-Federations (3) Usecases • NREN-Clouds (not reseller): not yet (relevant) in operation • NREN-Clouds: Not just a prolongationof HPC (due tocosts HPC isnoseamlessself-service, also missingelasticity) • SDN certainlygoodforTest&Projectenvironmentofadvancedusers (consider: useraccesstoControlPlane!), currently e.g. in GN3+. Foroperational traffic: later, whenstabilised BUT: Killer application still hardto find! FIA, Athens, 19th March 2014, P. Kaufmann/DFN
