  • End of day So we’ll start gentlyHopefully something for everyonePlease bear with me if seems obvious to you.Bear with my english accent and phrases/terminologyBasics and more advanced ideasPaul AngusEngineering and Science degreesCloudStack 2.13
  • Lead in with monkey joke about gartner
  • Do it as a quizSome people add on “must be on internet”
  • Across nearly all of our metrics
  • In this cloud era we are toldDespite how much engineering you do it will failSebastien Buemi escapes 200mph crash unhurt in ShanghaiSwiss, youngApril 2010
  • Cloud : modern, expects things to go wrong…if things get busy, he just sorts it out himeselfTraditional: We don’t like this guy, but he wont go away. relies on his staff, expects everything to work. If things get busy, its somebody elses problem
  • Design Phase – some tips from experienceRedundancy & resilience – again some thoughts on building redundancy and resilience into the infrastructureAutomation – some examples of automation in the building of a cs architecture.Finanally a ‘word’ on documentation.
  • Storage, networking, overall architects technical and managerialEverything is interconnected and feels like everything relies on everything elseSomeone chipping in can be invaluable – particularly if they have past experience.
  • Simple Architecture exampleFollowed by a Not so Simple exampleHorizontal Scale, but still a long way from a Production System
  • Multiple CloudStack Servers – same or remote locationsMySQL Servers – Master Slave, or ClusteredSecondary Storage – Lots and Lots of it, at least 2x Zones Primary CapacityXen, KVM Clusters + Pri Storage – 8TB max so Multiple VolumesvSphere Clusters with vCenterBare Metal or Local Storage HyperVisors for High I/O workloadsHorizontal Scale
  • Storage, networking, overall architects technical and managerialEverything is interconnected and feels like everything relies on everything elseSomeone chipping in can be invaluable – particularly if they have past experience.
  • One that gets everyone:Switchsupports 4096 VLANs - but not at the same time.Gotchas…[add more]
  • Private clouds – you have your current usage to judgePublic clouds harder to predict – is guided by offerings.
  • Performance and / or capacityStorageNetworkNetwork (to storage) is often the limiting factor as jump to 10 Gbe is large(Although LACP in XenServer 6.1 and ESXi 5.1 will help to mitigate this)Not much point being able to run VMs per host if only 1Gb/s link Not much point to 256GB RAM with a single quad core processor unless a specific workload.
  • Lack of reference architectures currently
  • I’ll look at the major CloudStack management elements – CSMan MySQLAnd then look at considerations if you’ve virtualised your management farm
  • How do we achieve that…>
  • Automation can come in multiple formsChef & Puppet – enterprise grade automation – works for in-house use (required infrastructure makes it less useful for SIs)KickStart and Python – enables to learn one language and stick to it, requires the interpreter to be installed, but Python is Shell scripts don’t have to be fancy – have to learn awk & sed – have to learn the different languages.API calls
  • Write configuration file. Conscious decision to limit the number of files required.Self contained (requires hypervisor installation files)Look at some elements of the file >

  • Take your pickOnly way to remember what you did,only way for others to replicateRun scripts from scratch impossible to update code and separately make changes

  • The business Use-Case’s for building clouds with Apache CloudStack

    1. 1. @ShapeBlue The business Use-Case’s for building clouds with Apache CloudStack Giles Sirett CEO, ShapeBlue Twitter: @ShapeBlue
    2. 2. @ShapeBlue Who am I ? CEO of ShapeBlue Been working with ACS since late 2011 PMC member & Committer Apache CloudStack Chairman – European CloudStack user group Technical enough to be dangerous (recovering developer) I’m a business guy
    3. 3. @ShapeBlue “ShapeBlue are expert builders of public & private clouds. They are the leading independent global CloudStack / CloudPlatform integrator & consultancy” About ShapeBlue
    4. 4. @ShapeBlue Global Consulting & Integration Teams
    5. 5. @ShapeBlue Enterprises Service Providers
    6. 6. @ShapeBlue vCloud Director Microsoft System Center Vendor tied Abiquo OnApp Felxiant Haexagrid End to end CloudStack OpenStack Opennebula Euacalyptus Open communities Your orchestration must be open to survive
    7. 7. @ShapeBlue Only CloudStack & OpenStack will survive
    8. 8. @ShapeBlue But why CloudStack Giles ? “It just works”
    9. 9. @ShapeBlue CloudStack Background • Open source Infrastructure-as-a-Service platform, under ASL 2.0 license • A vibrant and growing community in ASF – Developed since 2008 by – Acquired by Citrix in 2011 – Donated to Apache April 2012 – Became top level AF project March 2013 • A proven cloud platform
    10. 10. @ShapeBlue But why CloudStack Giles? Governance
    11. 11. @ShapeBlue “CloudStack is part of OpenStack, right ?” Our perception problem
    12. 12. @ShapeBlue 275
    13. 13. @ShapeBlue CloudStack Users
    14. 14. @ShapeBlue 15 CloudStack Users 2.0
    15. 15. @ShapeBlue 16 CloudStack Users 3.0
    16. 16. @ShapeBlue “CloudStack is part of OpenStack, right ?” CloudStack is not as well marketed as some other projcts
    17. 17. @ShapeBlue But, what about those Use – Cases’s ?
    18. 18. @ShapeBlue The obligatory cloud definition slide Self Service Resource pooling Rapid Elasticity Metered Use
    19. 19. @ShapeBlue Organisations are virtualised = cap/op ex savings However, operationally often still manual Still often a service ticket to provision new resources Long delivery times Relatively high operational costs Relies on specialist skills Margin for human error On-demand self-service is a driver
    20. 20. @ShapeBlue Make the most of a global compute estate Resources dynamically assigned according to demand Workloads can be averaged: across departments, across Geos, across times of day, days of month,etc By pooling resources, reduces the reliance on local capacity planning Abstracts physical resources Resource pooling is a driver
    21. 21. @ShapeBlue The The XaaS model allows accurate cost measurement Compute Storage Network etc Internal chargeback model much simpler “Shadow IT” can be removed Measured service is a driver
    22. 22. @ShapeBlue Scale up Scale back Autoscaling Burst capabilities WORKLOAD PORTABILITY Rapid elasticity is a driver
    23. 23. @ShapeBlue Service Provider / public cloud Devops automation AWS insourcing Traditional enterprise workloads So, todays use-case’s are…
    24. 24. @ShapeBlue Use case 1 of 4 - Service provider / public cloud $3,200,000,000
    25. 25. @ShapeBlue August 2012 = 90% public cloud vs other use cases Jan 2014 = 50/50 split
    26. 26. @ShapeBlue Use case 2 of 4 - Devops Deploy my code Only on my infrastructure
    27. 27. @ShapeBlue Rapid agility demanded by business continuous integration continuous delivery Automate, script, automate, script, automate, script EVERYTHING needs infrastructure Use Case 2 of 4 - Devops
    28. 28. @ShapeBlue Use Case 3 of 4 – “AWS Insourcing” 0 5 10 15 20 25 30 35 usage usage
    29. 29. @ShapeBlue Use Case 3 of 4 – “AWS Insourcing” 0 5 10 15 20 25 30 35 usage usage Known demand
    30. 30. @ShapeBlue I realise that AWS is costing too much for my known demand I need to know my tooling will work I need to use the same API I still want to burst to AWS I don’t want to get into a massive/complicated project Use Case 3 of 4 – “AWS insourcing”
    31. 31. @ShapeBlue Use Case 4/4 – Enterprise adoption
    32. 32. @ShapeBlue In 2013/14, we are seeing enterprises doing one of the following: adopt public cloud build private cloud align with public clouds (technology, process, standards) CloudStack has a unique position in the enterprise… Use Case 4/4 – Enterprise adoption
    33. 33. @ShapeBlue “The car was not a problem. I just lost both wheels." Failure happens – Get used to it
    34. 34. @ShapeBlue Cloud Era workload Traditional workload
    35. 35. @ShapeBlue Traditional workloads Traditional n-tier applications Scale & reliance handled by the infrastructure Scale by “scaling up” Infrastructure expected to be always available Traditional Workloads
    36. 36. @ShapeBlue Cloud era workloads Applications designed for failure Applications designed for massive scale Scale by “scaling out” (horizontally) How can an enterprise benefit from both models ? Cloud Era workloads
    37. 37. @ShapeBlue Private Cloud Enterprises want a 2 workload model
    38. 38. @ShapeBlue Collaborative environment for: all things CloudStack/ CloudPlatform Related tech: CloudPortal BM, CloudBridge, ecosystem products, hypervisors, storage, etc Technical deep-dives, issues & best practice Case studies & ideas To showcase complementary technologies Find us on LinkedIn: “CloudStack European User Group” The European CloudStack User Group
