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

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

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

61. 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

62. 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

63. Infrastructure 63Friday, April 20, 12

64. 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

65. 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

66. Platforms 66Friday, April 20, 12

67. 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

68. Agile Development ProcessesFriday, April 20, 12

69. 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
