13 Why TryStack?

14 SWOT for Strengths: Very broad ecosystem Open community Innovation + Open Source=Virtuous Cycle Opportunities: OpenAPI/Standard Hybrid Cloud Compatibility Weaknesses: Lack of IaaS experience for many developers Too many voices, enterprise level deployment will be delayed Interoperability Threats: Everyone want to build a distribution Forking and customization 2013/6/

17 TryStack.org is a Foundation project But Login with Facebook is not free for Chinese Users. 2013/6/

18 So we build TryStack.cn

19 Trystack.cn histroy September 6 th,2011 Shanghai Summit / shtml February 16 th,2012 TryStack.org launched September 20 th,2012 Foundation launched February 8 th, 2013 Trystack 1 st meetup in Nanjing ystack-cn-2013-first-meetup/ June 14 th, 2013 Trystack 3 rd, meetup in Beijing (IBM) trystack-cn-meetup-with-ibm-in-beijing/ January 8 th,2012 Chinese Developers Conference Auguest 10 th -11 th,2012 APAC Summit / Oct 2012 Grizzly Summit, Trystack.cn launched ck/trystack-introfinalpdf February 20 th, 2013 Trystack 2 nd meetup in Shanghai 3/02/trystack-2nd-meetup-2013/ April 15 th,2013 Havana Summit Trystack.cn update to Grizzly Cloud.trystack.cn June 21th,2013 Trystack.cn 4 th meetup in Shenzhen(Huawei) 2013/6/

20 What Trystack.cn - Experience Newest features. - Allow testing of reference architectures. - Help developers get familiar with the APIs. Enterprise Applications Deployment Support POCs Testing Staging PRIVATE CLOUD PUBLIC CLOUD Production TryStack.cn Private Cloud Public Cloud Don't believe me, believe yourself. Give it a try! 2013/6/

25 Networking challenges in the Cloud Multi-tenants on hypervisors => isolation between guest networks. VLANs in the datacenter is hard and limit at 4K VLANs. Hardware switches may not do it very well or have a lower limit. 2013/6/

26 Networking trend Move to software switches Move to L3 isolation Use tunnels between OVS (GRE tech preview) Program the network through API Encapsulation virtualizes the network, between overlays on overlays on overlays.. L3 on L2 on GRE on L3 on L2 Then you bring the WAN and you have: L3 on L2 on GRE on L3 on L2 on GRE on L3 on L2.Euhhhh!!! 2013/6/

27 Quantum Architecture API Clients Quantum Server Tenant Scripts Horizon Nova Uniform API for all clients Quantum API Create-net... Create-port API Extensions Quantum Plugin Create-net... Create-port DB Internal plugin communication. Nova Compute virtual switch Nova Compute Nova Compute Nova Compute Interfaces from a service like Nova plug in to a switch manages by the Quantum plugin. 2013/6/29 API + Plugin = Quantum Service 22

28 Quantum in Production API Clients Don't hack Quantum, just use Quantum API Tenant Scripts Horizon Nova Uniform API for all clients Be ready for SDN! Quantum Server Quantum API Create-net... Create-port API Extensions Choose the right plugin Quantum Plugin Create-net... Create-port DB Internal plugin communication. Use a Networking Controller External Manager DB Nova Compute virtual switch Nova Compute Nova Compute Nova Compute Interfaces from a service like Nova plug in to a switch manages by the Quantum plugin. 2013/6/29 API + Plugin = Quantum Service 23

29 In multihost env, all compute hosts will run nova compute,quantum ovsagent,dhcp agent andl3 agent. DHCP and L3 agents serve only the local VMs. 2013/6/

30 In the run time,quantum L3 agent will use the DHCP agent s namespace to enforce the L3 feature.since DHCP is isolated network metadata service serves the subnets which have no gateway,it cannot be used in multihost env.to access metadata service,the L3 agent s metadata access service should be used. 2013/6/
