  • 1. From Cloud Computing to Platform as a Service Andy Piper @andypiper (MBCS CITP)
  • 2. Hello I’m Andy
  • 3. This morning! Reminded by my cloud-native Little Printer…
  • 4. Developer Advocate @ Cloud Foundry ! maker, hacker, educator, LEGO fan podcaster, writer Open Source contributor Eclipse Project Lead (Paho / MQTT) ! excited by “what’s next”, Internet of Things, etc. a few things about me
  • 5. My background
  • 6. Today’s topic: Cloud!
  • 7. So what do we know 
 about “The Cloud”…?
  • 8. 29% an actual cloud 51% believe affected by weather 54% say they never use (but 95% turn out to do so) 20% pretend to know ... 16% know it means computer services 68% say it’s good, when explained... What the heck is “The Cloud”? Citrix study (1,006 person survey)
  • 9. 1. Cloud, and how we got here 2. Platform as a Service? 3. Why Open Source will rule the Cloud
  • 10. How did we get here?
  • 11. 1st MAINFRAME 3rd CLOUD Automation of financial accounts ISAM 2nd CLIENT-SERVER & WEB Automation of most paper processes: ERP, CRM, Email, … pioneered by new Consumer Internet giants – requires a new Application Fabric New Data-fabrics Mainframes c. 1960s-1980 New Experiences New Biz Models Relational Databases Mini’s & PC’s c. 1980s-2000s Eras of Computing Cloud-Enabled Datacenter mid-2000s … now
  • 12. Gmail, Salesforce, Flickr, Google Docs... Software Google AppEngine, Heroku, Cloud Foundry, EngineYard, OpenShift, Azure, Apprenda... Platform Infrastructure 3 layers Amazon EC2, Google CE, OpenStack, vSphere, Rackspace, Cloud Stack, Eucalyptus... IaaS, PaaS, SaaS
  • 13. They brought the virtualised infrastructure Infrastructure as a Service
 = the new hardware
  • 14. Infrastructure Clouds - consumer web companies built out according to their own needs to support Software
  • 15. They brought the APIs and data (aka MBaaS) APIs - mashups, data, agility
  • 16. But - still need to build & manage Platform
  • 17. They brought the rapid development push ‘myapp’ -> running
  • 18. They brought the business challenge data leads to advantage
  • 19. Characteristics of the Cloud • vast scale • decreasing cost • agility of delivery (even at scale) • rapid data analysis and iteration (“big data”) • innovation
  • 20. To succeed where those guys have? Platform
  • 21. Characteristics of PaaS • Applications and Services (data) are kings • Opinionated! • De-emphasised infrastructure / hardware 
 (VM, kernel, disk, network etc) • An “operating system” for IaaS
  • 22. Rumours of the demise of PaaS are greatly exaggerated…
  • 23. Why Open wins
  • 24. From: torvalds@klaava.Helsinki.FI Newsgroups: comp.os.minix Date: 25 Aug 91 20:57:08 GMT Organization: University of Helsinki 1991 An important year in software Hello everybody out there using minix ! I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu) for 386(486) AT clones.
  • 25. 21+ years later: Linux has won
  • 26. #P0WN ALL TEH GADGETZ ! Linux runs everywhere (even old versions, on crashy airline entertainment systems...)
  • 27. It runs on Windows Azure! Jun 2012, w. Canonical
  • 28. Linux is ubiquitous (but often invisible)
  • 29. It works.
  • 30. No single language to “rule them all”
  • 31. Data gets bigger (and faster, and needs analysis, and SCIENCE)
  • 32. Composability is key
  • 33. An Operating System for the Open Cloud Multi-IaaS, Multi-Framework, extensible…
  • 34. Open & public from the start Code all on Github
  • 35. Infrastructure ! Clouds (CPI) Runtimes and ! Frameworks All about Choice Data Services
 and APIs composability is key…
  • 36. The 2014 Cloud Forecast?
  • 37. more developers
 building ! more awesome apps & services 
 in the OPEN
