  3. 3. @chanezon French Polyglot Server Side San FranciscoDeveloper Relations
  4. 4. Cloud Platforms allow developersto take risks, become more agile and focus on building business value instead of infrastructure
  5. 5. Patrick Chanezon Senior Director Developer @chanezon
  6. 6. Very freely inspired from ... the story of my grandfatherand a few years as an Enterprise consultant in France before moving to California
  7. 7. My grandfather, missed the transition from Radio to TV in the 1950’s
  8. 8. 2010- George became CIO
  9. 9. What happened whileGeorge was playing Golf
  10. 10. Dreams Of my childhood33
  11. 11. 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!34
  12. 12. 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 craft35
  13. 13. Predictions “The future is already here — its just not very evenly distributed” William Gibson36
  14. 14. Architecture Changes: 60’s Mainframe
  15. 15. Architecture Changes: 80’s Client-Server
  16. 16. Architecture Changes: 90’s Web
  17. 17. Architecture Changes: 2010’s Cloud, HTML5, Mobile
  18. 18. Back to Client Server: Groovy Baby!41
  19. 19. What is Cloud Computing? - End Users42 Cloud According to my daughter Eliette
  20. 20. What is Cloud Computing? - Analysts Software As A Service Platform As A Service Infrastructure As A Service43
  21. 21. What is Cloud Computing? - Developers Software As A Service Platform As A Service Infrastructure As A Service44
  22. 22. 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 craftmanship45
  23. 23. 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
  24. 24. Google research papers: good predictor of where BigData is going• Horizontal scalability 2004: Map/Reduce (Hadoop)• NoSQL 2006: Bigtable (Mongo, Cassandra, HBase, Riak)• Real Time analytics 2010: Dremel, BigQuery (Impala)• Horizontally Scalable SQL 2012: Spanner/ Amazon Redshift
  25. 25. Infrastructure48
  26. 26. IaaS/Virtualization getting mainstream§ AWS, Joyent, Rackspace,...§ Open Source projects: OpenStack, CloudStack, Eucalyptus§ Automation: Chef, Juju, Cloud Foundry BOSH§ 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, upgrades49
  27. 27. 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 • • • •§ 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 happens50
  28. 28. Platforms51
  29. 29. 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-in52
  30. 30. Agile Development Processes
  31. 31. 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 value54
  32. 32. 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!55

  50. 50. Cloud Foundry BOSHCloud Foundry BOSH is an open source tool-chain for release engineering, deployment, and lifecyclemanagement of large scale distributed services• Prescriptive way of creating releases and managing systems and services• It is not a collection of shell scripts, not a pile of PerlBuilt to deploy and manage production-class, large scale clusters• Production grade Cloud Foundry clusters: 500+ VMs, 40+ jobs, 75+ packages• Multi-node, multi-tier, complex clusters: e.g., our Gerrit/Jenkins ClusterBuilt for devops usage and scale by a crack team of veterans• A project, not a product: command line interface, YAML, etc.• Continuous improvement, iterative development, rough edges

  53. 53. Lessons for Developers76
  54. 54. 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
  55. 55. Things to forget • First normal form • Waterfall model • Single server deployment • Single language skill • Build everything from scratch • Build custom infrastructure78
  56. 56. 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
