Java in the Cloud

The cloud is one of those leading paradigm shifts that only happen every 10-15 years. Like other shifts before it (virtualization, offshoring, etc.), the cloud will profoundly impact the IT industry at large. No profession, no sector will remain shielded from the changes brought by the cloud.

Sacha Labourey, CEO of CloudBees and former CTO of JBoss, will first discuss how cloud computing is a natural step in the evolution and maturation of IT. He will then dig into what those changes mean for Java developers. Finally, he will discuss what choices Java developers are facing and will demonstrate what the future of Java developers might practically look like.

  2. 2 • Born in 1975 in Switzerland • JBoss –

    Clustering lead – 2001 – GM Europe - 2003 – CTO - 2005 • Red Hat – JBoss acquisition in June 2006 – co-GM of Red Hat’s middleware division – Left Red Hat in April 2009 • CloudBees – Started in April 2010 – About 30 bees in 6 countries Introduction – Sacha Labourey ©2012 CloudBees, Inc. All X
  3. 3 • A story backwards… • Cloud Computing - The

    Inexorable • What does “Cloud” mean to developers? – IaaS vs. PaaS vs. SaaS • Weather forecasts • Demo… Agenda ©2012 CloudBees, Inc. All
  4. 4 • We are pretty good at predicting what’s …

    predictable! – No disruption, “constant speed” Business as usual… ©2012 CloudBees, Inc. All A B C ?
  5. 5 • When important paradigm shifts take place, it is

    hard to project yourself in the future… • But once you sit “on the other side” of the shift, the changes it brought with it seem obvious – Did someone/your kids ever ask you why phones used to have a cord? • What could be the impact of Cloud Computing on IT? And on developers’ jobs? Let’s go through a story you probably know very well… Beware, paradigm shift ahead! ©2012 CloudBees, Inc. All
  6. 6 • During the 19th century, the frst electrical generators

    appeared • Some companies set up their own generators for their own use – Complex, fragile, very costly – Absolutely not accessible to the mass market The frst electricity consumers/producers ©2012 CloudBees, Inc. All
  7. 7 • Cities start investing in power plants • At

    the end of the 19th century, the frst power plants emerge – 1878 – Exposition Universelle de Paris – 1879 – St-Moritz (Switzerland) – 1882 – London & NYC – 1883 – Grenoble – 1884 – Le Locle Electricity starts being democratized ©2012 CloudBees, Inc. All

  9. 9 Some nice buildings (La Chaux-de-Fonds) ©2012 CloudBees, Inc. All

    Those are the “Googleplex” of the 19th century!
  10. 10 • Very costly • No standards – AC? DC?

    – What frequency? – 110V, 220V, 230V, 240V, other? – Plug? What plug? – Redundancy? SLA? Yet, this was not as simple as it seems… ©2012 CloudBees, Inc. All

  13. What is the state of IT today? ©2012 Cloud Bees,

    Inc. All
  14. 14 Today’s IT feels very much like electrical generators from

    the 19th century Flashback Google Data Center Could IT evolve in a similar fashion? ©2012 CloudBees, Inc. All
  15. 15 Sometimes, IT can be rudimentary…

  16. 16 Sometimes, it is chaos…

  17. 17 « And yet it moves »

  18. 18 • We are treating IT as “haute couture” –

    Custom, “sur mesure” – Unique – Costly – High overhead IT today ©2012 CloudBees, Inc. All
  19. 19 The cloud

  20. 20 • In 2006, Amazon announces AWS – Thanks Jeff

    – ~Doubling every year • Today, many traditional providers are being “cloudifed” – Hosting providers  IaaS providers – Middleware vendors  PaaS providers – ISVs  SaaS The Cloud revolution has started ©2012 CloudBees, Inc. All
  21. 21 The growth of data centers

  22. 22 Data centers – some examples

  23. 23 The cloud will do to IT, what electricity has

    done to the industry - “If you don’t like change, you are going to like irrelevance even less.” -- Gen. Erik Shineski ©2012 CloudBees, Inc. All
  24. 24 Cloud computing – quick analogy Power Plants Cloud Providers

  25. 25 But what does it mean to me, as a

    software developer?!? Fine… ©2012 CloudBees, Inc. All
  26. Cloud 101 The cloud for the not-so-dummies ©2012 Cloud Bees,

    Inc. All

  29. 29 Easy: « Just use a XaaS! » ©2012 CloudBees,

    Inc. All
  30. 30 A what?!? ©2012 CloudBees, Inc. All Let’s decrypt These

    together
  31. 31 • AWS – the most popular example • Server

    Lego blocks – VM, storage, IP, etc. • Development environment: – “Give me a server, an OS, a virtualization layer, an application server, a frewall, a database, I’ll deal with it! And patch it. And monitor it. And…” – Flexible but cOmpLiCaTed • User point of view – Custom systems and environments IaaS ©2012 CloudBees, Inc. All
  32. 32 IaaS – Congratulations! ©2012 Cloud Bees, Inc. All “Great”

    news: you have now become responsible for the data-center!
  33. 33 ©2012 CloudBees, Inc. All See, I can do whatever

    I want with those Legos!
  34. 34 ü Directly managing your IaaS resources provides you with

    resource elasticity (CAPEX-free), but… O The amount of soft-IT typically required to do so is … higher! – All of the traditional IT activities remain (maintain/patch/monitor OS+JVM+AS+DB++, etc.) – + cloud-specifc items: elasticity/security/automation • My advice? Move on… IaaS – Consequences ©2012 CloudBees, Inc. All
  35. 35 • SalesForce.com, Zendesk, NetSuite, etc. • Development environment –

    Rigid – mostly through CONFIGURATION – When available “development” takes place within the SaaS itself • User point of view – Standard applications – Very fast bootstrap – Most of the time, lock-in is very high SaaS ©2012 CloudBees, Inc. All
  36. 36 ©2012 CloudBees, Inc. All

  37. 37 ©2012 CloudBees, Inc. All

  38. 38 • Development environment – “Give me my typical development

    environment and manage everything else for me – servers, scalability, failover, backups, etc.” • User point of view – Custom applications (Lots of different philosophies though!) PaaS ©2012 CloudBees, Inc. All
  39. 39 ©2012 CloudBees, Inc. All Your application … Platform core

    services IaaS Provider
  40. 40 ©2012 CloudBees, Inc. All

  41. 41 ©2012 CloudBees, Inc. All Load balancer ü Round robin

    ü Sticky sessions
  42. 42 ©2012 CloudBees, Inc. All Session replication

  43. 43 ©2012 CloudBees, Inc. All Auto-scale

  44. 44 • Applications and data are at the center of

    your world! – Forget about servers, VMs, load-balancers, etc. • Cloud concepts are applied to applications as frst class citizens – On-demand, pay-as-you-go, elasticity, etc. – No need to handle updates, patches, scalability, failover, etc. This is a Service, not just some Software! PaaS ©2012 Cloud Bees, Inc.
  45. 45 1st decision: IaaS, SaaS or PaaS? ©2012 CloudBees, Inc.

    All Iaas Juggle with technologies Saas Constraint Paas Flexible
  46. 46 PaaS – the new platform for developers ©2012 CloudBees,

    Inc. All Paas Flexible
  47. 47 • Could I please get a « Private PaaS

    »? – Sure! We can also sell you a private jet! – Very tempting! All of the advantages but no decision about the cloud is needed! And I’ll be able to customize it! • Yes, but… – A great part of the value from a PaaS comes from the « S »: SERVICE • With a public PaaS, you are outsourcing your Operations & DevOps – With a Private PaaS you’ll get improve the« interface » between DEV and IT compared to traditional middleware, but … you remain in charge of all operations! – And remember: Customization is the root of all evil! • « Can I get a 160V plug just for this toaster? » One word of caution… ©2012 CloudBees, Inc. All
  48. Yeah, but do I even need the cloud? And if

    I do, why now? ©2012 Cloud Bees, Inc. All
  49. 49 Important changes are taking place • Mobile • Social

    • Local • Big Data • Consumerization of IT • HTML5 • Component reuse • Open Source • Agile SCRUM

  53. 53 Mobile Internet - 10x bigger! Thanks to Mary Meeker

    and Matt Murphy, From David Skok presentation @ MassTLC
  54. 54 How to handle that massive increase? 54

  55. 55 How to handle… 55 10x more aplications! Hire 10x

    more developers? Pay 10x smaller salaries? Become 10x more productive?
  56. 56 1. Value failure 2. Increase productivity Solutions 56

  57. 57 About 25% of the projects fail … and failure

    is bad, right? So let’s « force » success… Let’s increase budget… Let’s extend the deadlines… Let’s reduce the scope… Let’s reduce expectations… Bottom line, let’s succeed! (easy) Valuing failure?!? 57 source: http://bit.ly/aaPgxe
  58. 58 Since we have to deliver 10x more applications… …Are

    100% of those ideas necessarily good ideas? NO! …Can we always know that beforehand? NO! If an idea is a BAD idea, we’d better know that fast  FAIL-FASTER!!! 1. We must INCREASE the failure rate 58 Must read: http://speakerdeck.com/u/searls/p/the-mythical-team-month
  59. 59 1. Fail-Faster - Fail-Smaller 59 Idea 1 Idea 2

  60. 60 1. Failing FAST with FEW resources is GOOD! “Repeat

    after me” 60
  61. 61 Doing small & fast projects is a great idea…

    except if FRICTION between DEV and IT remains constant  very hard to scale!  We must DROP friction between DEV and IT! 2. Increase productivity 61
  62. OK, but how do I do that? Use a PaaS!

  63. 63 Before PaaS Source Code Managemnt Jenkins Continuous Integration Unit

    Test Functional Test Load Test Integration Test Developer “Cloud you please provision a server for me?” “Could I get X, Y and Z installed on that server?” “Could you please patch my server?” “Could I please get a database dump?” Could I get a new Git server? Where could I run my Jenkins integration tests? IT

  67. Does it even work?!? 67 BULLSHIT 2.0 ?

  68. 68 • LoseIt! – Facts • Mobile Application • >12

    million users • >25’000 tx/minute • Real-time activity monitoring • Several releases a week • loseIt! – Reality • 4 employees total • 2 developers • 2 marketing • 0 IT/operations •  4 employees 68 ü
  69. 69 The cloud is … not secure! … not stable!

    The real question is more probably: What will you do when a “loseIt!” will be a competitor in your feld? (hint: be that“LoseIt!”) “If you don’t like change, you are going to like irrelevance even less.” -- Gen. Erik Shineski “Well, I am not too much of a cloud guy…” 69
  70. 70 • Need for new data and applications is going

    to explode! • It will become key to value failure and increase productivity • New tools and processes are needed to achieve this • PaaS is the new platform for developers • The future is now! Conclusion 70
