DEFINITION OF CLOUD COMPUTING(Network-based) access to a pool of data center resources(servers, storage, applications, inter-connect, firewalls, )Key characteristics lease, not own economies of scale location independent on-demand, reconfigurable, elasticService models are based on how cloud resources are offeredDeployment modes are based on who uses the cloud The type of network access plays a big role10 Copyright 2010 Juniper Networks, Inc.
  • 11. SERVICE MODELS Layer of Infrastructure Offered Service Use our Offer software/application built on top cloud-based software Offer resources as a platform Write your own software Offer raw compute resources Build your own DC11 Copyright 2010 Juniper Networks, Inc.

DEPLOYMENT MODELSPrivate cloud owned or leased by an enterprise private accessCommunity cloud shared infrastructure for community (e.g., set of enterprises) access limited to communityPublic cloud mega-scale infrastructure for public use public accessHybrid cloud composition of two or more types of clouds12 Copyright 2010 Juniper Networks, Inc.

  • 14. PROPERTIES OF CLOUDSAll the resources of cloud computing have several propertiesthat are crucial to the success of this paradigm Fungibility Elasticity Reconfigurability (Resource) Mobility VirtualizabilityThese same properties are required of cloud networking!14 Copyright 2010 Juniper Networks, Inc.
  • 15. FUNGIBILITYBuild computing infrastructure Build the network infrastructurewith the fewest pools of with the fewest pools ofindependent resources independent resources IaaS: pick a standard CPU, Interconnect: Ethernet, FCoE emulate others as needed L2: Ethernet, VLANs, MACs Storage: offer block access, L3: IP, IP addresses via FCoE/iSCSI; filesystems L4-L7: virtualized firewalls, PaaS: different platforms, load balancers, DPI engines languages, SDKs SaaS: straightforwardSingle physical resource?

  • 16. ELASTICITY Compute resources allocated Network resources allocated on demand (scheduled), on demand (scheduled), resized dynamically (real-time) resized dynamically (real-time) CPU cycles Bandwidth RAM IP/MAC addresses Storage Auxiliary services (DPI, fw) Limits and time bounds may Again, limits and time bounds be placed up front may be needed Metered use Metered use16 Copyright 2010 Juniper Networks, Inc.
  • 17. RECONFIGURABILITY, MOBILITYReconfiguration and mobility of the underlying resources arealike and have similar constraintsReconfiguring or moving compute resources MUST be done intandem with reconfiguring or moving network resourcesMoves in particular require that the network be aware that thecustomer application may be in two places for a short duration,and has to assist the transition with routing, switching and otherservicesWhile clever algorithms allow reconfiguration and moves to bein service and reduce the impact on customer applications,there may be a need to pause the apps for a short duration17 Copyright 2010 Juniper Networks, Inc
