From Cloud Computing to Platform as a Service – BCS Oxfordshire
- 1. From Cloud Computing to Platform as a Service Andy Piper @andypiper (MBCS CITP)
- 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
- 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
- 23. Rumours of the demise of PaaS are greatly exaggerated…
- 24. Why Open wins
- 25. 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.
- 26. 21+ years later: Linux has won
- 27. #P0WN ALL TEH GADGETZ ! Linux runs everywhere (even old versions, on crashy airline entertainment systems...)
- 28. It runs on Windows Azure! Jun 2012, w. Canonical
- 29. Linux is ubiquitous (but often invisible)
- 30. It works.
- 31. No single language to “rule them all”
- 32. Data gets bigger (and faster, and needs analysis, and SCIENCE)
- 34. An Operating System for the Open Cloud Multi-IaaS, Multi-Framework, extensible…
- 35. Open & public from the start Code all on Github
- 36. Infrastructure ! Clouds (CPI) Runtimes and ! Frameworks All about Choice Data Services and APIs composability is key…
- 38. more developers building ! more awesome apps & services in the OPEN
