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.

1. Developers, Welcome to the Cloud! Sacha Labourey CEO, CloudBees, Inc. May 9, 2012 – San Francisco Photo credit: @romainguy ©2012 CloudBees, Inc. All Rights Reserved
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.

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 Electrical Grids The Internet Electrical Plug Web Browser ©2012 CloudBees, Inc. All
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
27. 27 Traditional software stack ©2012 CloudBees, Inc. All Server Hypervisor VM AS JVM LB Application You
28. 28 ©2012 CloudBees, Inc. All Servers OS VM AS JVM LB Applications Cloud Computing: How to do it? Who does what? Cloud Provid er?
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 Idea 3 Idea 4 Idea 5 Idea 6 Idea 7 Idea 8 DEV+IT TEAM App 1 App 2 App 3 App 4 Idea 5 Idea 6 Idea 7 Idea 8 Idea 1 Idea 2 Idea 3 Idea 4 DEV TEAM Dev 1 Dev 2 Dev 3 Dev 4 App 1 App 2 App 3 App 4 App 5 App 6 App 7 App 8
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! 62
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
64. 64 With PaaS Source Code Managemnt Jenkins Continuous Integration Unit Test Functional Test Load Test Integration Test Developer Create a new account Create a new Git repository Create my new Jenkins testsuite Deploy my app and test it Deploy my production app with HA Done PaaS Portal

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
