  • Portrait of the developeur as
  • @chanezon French Polyglot Server Side San FranciscoDeveloper Relations
  • Patrick Chanezon Senior Director Developer Relationschanezonp@vmware.com @chanezon View slide
  • Very freely inspired from ... and a few years as anEnterprise consultant in France before moving to California View slide
  • 2010- George became CIO
  • What happened whileGeorge was playing Golf
  • Dreams Of my childhood30
  • Accelerando / Singularity, in a Galaxy far far away§ Even if we automate ourselves out of a job every 10 years§ ...I don’t think the singularity is near!31
  • Moores Law is for Hardware Only§ Does not apply to software§ Productivity gains not keeping up with hardware and bandwidth§ Writing software is hard, painful, and still very much a craft32
  • Predictions “The future is already here — its just not very evenly distributed” William Gibson33
  • Architecture Changes: 60’s Mainframe
  • Architecture Changes: 80’s Client-Server
  • Architecture Changes: 90’s Web
  • Architecture Changes: 2010’s Cloud, HTML5, Mobile
  • Back to Client Server: Groovy Baby!38
  • What is Cloud Computing? Cloud According to my daughter Eliette39
  • Cloud Stack - Classic Pyramid Software As A Service Platform As A Service Infrastructure As A Service40
  • Cloud Stack - By Value Software As A Service Platform As A Service Infrastructure As A Service41
  • Cloud Stack - History§ What does cloud mean, 4 main angles • Software 1994 Netscape • Infrastructure 2002 Amazon AWS • Platform 2008 Google • Development now! § Industrialization of hardware and software infrastructure like electricity beginning of 20th century§ But software development itself is moving towards craftmanship42
  • Cloud started at Consumer websites solving their needs• Google, Amazon, Yahoo, Facebook, Twitter• Large Data Sets• Storage Capacity growing faster than Moore’s Law• Fast Networks• Vertical -> Horizontal scalability• Open Source Software• Virtualization• Cloud is a productization of these infrastructures • Public Clouds Services: Google, Amazon • Open Source Software: Hadoop, Eucalyptus, Ubuntu, Cloud Foundry
  • Infrastructure44
  • IaaS/Virtualization getting mainstream§ AWS, Joyent, Rackspace,...§ Open Source projects: OpenStack, DeltaCloud, Eucalyptus§ Automation: Chef, Juju, Cloud Foundry BOSH§ Standardization? DMTF§ Inside the Firewall, Virtualization: VMware, Microsoft, Xen, KVM§ 60% of workloads are virtualized in 2012§ Easy to provision, manage instance...BUT§ Still need to manage backups, software stacks, monitor, upgrades45
  • With Infrastructure, you still need to build your own platform§ Need to build a distributed platform on top of you infrastructure§ Story of the AWS meltdown from last summer • http://blog.reddit.com/2011/03/why-reddit-was-down-for-6-of-last-24.html • http://www.readwriteweb.com/cloud/2010/12/chaos-monkey-how-netflix-uses.php • http://news.ycombinator.com/item?id=2477296 • http://stu.mp/2011/04/the-cloud-is-not-a-silver-bullet.html§ Twilio, Smugmug, SimpleGeo survived it because they built their own distributed platform on top of IaaS§ Enterprise customers want to consider Infrastructure like CDNs • Multi Cloud usage • Based on Open Source de facto standards, or full standards whenever that happens46
  • Platforms47
  • Platforms§ Raise the Unit of currency to be application & services instead of infrastructure§ Google App Engine, Cloud Foundry, Heroku, CloudBees, Amazon Elastic Beanstalk, Microsoft Azure, AppFog§ Single or a few languages, services§ Start of Multi language Polyglot platforms§ Enabler for Agile Developers -> Create Business value faster§ Lack of standards: risk, vendor lock-in§ Enterprise needs: •Control, customizability •Private/Hybrid Cloud •Avoid lock-in48
  • Agile Development Processes
  • Agility as a survival skill§ Consumer software is becoming like fashion •Phone apps, social apps, short lifetime, fast lifecycles •A/B testing§ Enterprise •Clay shirky situational apps§ Kent Beck, Usenix 2011 Talk, “Software G-Forces: the effects of acceleration” change in software process when frequency grows§ Cloud Platforms enables an Agile culture, driver for innovation •Scalability is built in the platforms •Can iterate faster •Focus on design§ Cloud Platforms lets developers focus on driving business value50
  • Main Risk: Lock-In Welcome to the hotel california Such a lovely place Such a lovely face Plenty of room at the hotel california Any time of year, you can find it here Last thing I remember, I was Running for the door I had to find the passage back To the place I was before ’relax,’ said the night man, We are programmed to receive. You can checkout any time you like, But you can never leave!51

  • Lessons for Developers76
  • Predictions • Software is becoming like fashion, design rules • Welcome to Babel, use the best tool for the job, embrace multiple language & heterogeneity • Our jobs will change, build yourself out of your current job • Sysadmin jobs will morph, there will be less of them • Many opportunities open when you embrace change77
  • Things to forget • First normal form • Waterfall model • Single server deployment • Single language skill • Build everything from scratch • Build custom infrastructure78
  • Things to learn • Agile • Take risks, fail often, fail fast and learn • API Design: create the API first • UI Design, Javacript, HTML5, CSS3 • A/B Testing • Open Source, Open Standards • Architecture, Distributed Computing (CAP theorem, 8 fallacies) • Cloud Platforms and APIs • Multiple types of languages (imperative, object, functional, logic) • Ability to encapsulate domain knowledge in a DSL • Build on the shoulders of giants: reuse, REST APIs • Pick your battles, choose what you need to build yourself to add value • Learn to live in a box (embrace platform limitations) to think outside the box • Use an App Store for distribution79
