cloud foundry, the open platform as a service
DESCRIPTION
This talk will provide an overview of the PaaS (Platform as a Service) landscape, and will describe the Cloud Foundry open source PaaS, with its multi-framework, multi-service, multi-cloud model.Cloud Foundry allows developers to provision apps in Java/Spring, Ruby/Rails, Ruby/Sinatra, Javascript/Node, and leverage services like MySQL, MongoDB, Reddis, Postgres and RabbitMQ. It can be used as a public PaaS on CloudFoundry.com and other service providers (ActiveState, AppFog), to create your own private cloud, or on your laptop using the Micro Cloud Foundry VM.The talk will end with a demo of Cloud Foundry in action, showing the end to end development workflow, from developing locally with Micro Cloud Foundry to deploying on Cloud Foundry.com.If you want to get started with Cloud development, bring your laptops, check the requirements and download pre-requisites at https://cloudfoundry.com/micro, and we'll help you setup your environment and get started with Cloud Foundry on your local machine.TRANSCRIPT

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, cf The Big Switch, Nick Carr
§ But software development itself is moving towards craftmanship
14

Crossing the Chasm
§ Build the whole product
§ Cloud getting mainstream: Apple iCloud
§ Opportunities and risks
§ Ecosystems, various platforms
15

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
• Horizontal -> Vertical 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

Infrastructure
Wednesday, November 9, 11
IaaS/Virtualization getting mainstream
§ AWS, Joyent, Rackspace,...
§ Open Source projects: OpenStack, DeltaCloud, Eucalyptus
§ Automation: Chef, Juju
§ Standardization? DMTF
§ Inside the Firewall, Virtualization: VMware, Microsoft, Xen, KVM
§ Easy to provision, manage instance...BUT
§ Still need to manage backups, software stacks, monitor, upgrades

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

Platforms
Wednesday, November 9, 11
Platforms
§ Raise the Unit of currency to be application & services instead of infrastructure
§ Google App Engine, Cloud Foundry, Joyent, Heroku, Stax (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
21

Agile Development Processes
Wednesday, November 9, 11
Agility as a survival skill
§ Consumer software is becoming like fashion•Phone apps, social apps, short lifetime, fast lifecycles
•Ab testing
§ Clay shirky situational apps
§ Kent Beck, Usenix 2011 Talkchange 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
