From Cloud Computing to Platform as a Service – BCS Oxfordshire

  1. 1. From Cloud Computing to Platform as a Service Andy Piper @andypiper (MBCS CITP)
  2. 2. Hello I’m Andy
  3. 3. This morning! Reminded by my cloud-native Little Printer…
  4. 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. 5. My background
  6. 6. Today’s topic: Cloud!
  7. 7. So what do we know 
 about “The Cloud”…?
  8. 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. 9. 1. Cloud, and how we got here 2. Platform as a Service? 3. Why Open Source will rule the Cloud
  10. 10. How did we get here?
  11. 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. 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. 13. They brought the virtualised infrastructure Infrastructure as a Service
 = the new hardware
  14. 14. Infrastructure Clouds - consumer web companies built out according to their own needs to support Software
  15. 15. They brought the APIs and data (aka MBaaS) APIs - mashups, data, agility
  16. 16. But - still need to build & manage Platform
  17. 17. They brought the rapid development push ‘myapp’ -> running
  18. 18. They brought the business challenge data leads to advantage
  19. 19. Characteristics of the Cloud • vast scale • decreasing cost • agility of delivery (even at scale) • rapid data analysis and iteration (“big data”) • innovation
  20. 20. To succeed where those guys have? Platform
  21. 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. 22. Rumours of the demise of PaaS are greatly exaggerated…
  23. 23. Why Open wins
  24. 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. 25. 21+ years later: Linux has won
  26. 26. #P0WN ALL TEH GADGETZ ! Linux runs everywhere (even old versions, on crashy airline entertainment systems...)
  27. 27. It runs on Windows Azure! Jun 2012, w. Canonical
  28. 28. Linux is ubiquitous (but often invisible)
  29. 29. It works.
  30. 30. No single language to “rule them all”
  31. 31. Data gets bigger (and faster, and needs analysis, and SCIENCE)
  32. 32. Composability is key
  33. 33. An Operating System for the Open Cloud Multi-IaaS, Multi-Framework, extensible…
  34. 34. Open & public from the start Code all on Github
  35. 35. Infrastructure ! Clouds (CPI) Runtimes and ! Frameworks All about Choice Data Services
 and APIs composability is key…
  36. 36. The 2014 Cloud Forecast?
  37. 37. more developers
 building ! more awesome apps & services 
 in the OPEN
  38. 38. Connect
