Back to Client Server: Groovy Baby! 57Friday, April 20, 12

What is Cloud Computing? Cloud According to my daughter Eliette 58Friday, April 20, 12

Cloud Stack - Classic Pyramid Software As A Service Platform As A Service Infrastructure As A Service 59Friday, April 20, 12

Cloud Stack - By Value Software As A Service Platform As A Service Infrastructure As A Service 60Friday, April 20, 12

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 craftmanship 61Friday, April 20, 12

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 FoundryFriday, April 20, 12

Infrastructure 63Friday, April 20, 12

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 § 50% of workloads are virtualized § Easy to provision, manage instance...BUT § Still need to manage backups, software stacks, monitor, upgrades 64Friday, April 20, 12

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 happens 65Friday, April 20, 12

Platforms 66Friday, April 20, 12

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-in 67Friday, April 20, 12

Agile Development ProcessesFriday, April 20, 12

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 value 69Friday, April 20, 12

Lessons for Developers 74Friday, April 20, 12

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 change 75Friday, April 20, 12

Things to Forget § First normal form § Waterfall model § Single server deployment § Single language skill § Build everything from scratch § Build custom infrastructure 76Friday, April 20, 12

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 distribution 77Friday, April 20, 12
