Sam Ramji, CEO
Cloud Foundry Foundation
The Making of a Cloud Native Platform

2. The Dawn of a New Era

3. A shift in business matching
the shift in human behavior

4. Since 2000, 52% of the Fortune
500 are no longer on the list

6. Continuous Innovation

7. January 21: Cloud Foundry Foundation
June 22: Open Container Initiative
July 21: Cloud Native Computing Foundation

8. Question 1:
Why are there so many foundations?

9. Open source has won. Popular projects
are now economically attractive.
This breeds competition and distrust.

10. The move to multi-vendor open
source enables competing
corporations to collaborate.

27. Food for thought

28. “There are 9 projects (Linux, KDE, Apache, Eclipse, Perl+CPAN, Mozilla+Addons,
Gnome, Drupal and GNU) that stand out as significantly larger - roughly 10 times -
than any others.
All of these projects, categorized as "XtraLarge", are developed as collaborative
community projects governed by non-profit foundations.
No single vendor project has so far been even close to reaching their magnitude.
There appears to be a glass ceiling limiting the growth of the Large single-vendor
projects (MySQL, Qt, OpenOffice, Mono, JBoss).”

29. Question 2:
How do all these technologies work together?

30. Any meaningful technology
has a movement around it

31. For Linux,
the movement was
open source

32. We now live in an age of
open source

34. We live in an age of
open source datacenters

35. Carrier Networking
Datacenter Networking
Datacenter Operating Systems
Hardware
Virtual Machines
Operating Systems
Application Platforms
Programming Frameworks
Containers

36. Any meaningful technology
has a movement around it

37. For Cloud Foundry,
the movement is
continuous innovation

38. For Docker,
the movement is
continuous innovation

39. For Kubernetes,
the movement is
continuous innovation

40. For CoreOS,
the movement is
continuous innovation

41. For Mesos,
the movement is
continuous innovation

42. Continuous Innovation
Continuous Deployment
Continuous Integration

43. waterscrumfall

44. dev+ops

45. Microservices
Containers
12-Factor Applications

46. Ephemeral
Scalable
Agile

47. Run in the cloud
Support any client device
Connect to legacy data and processes via APIs

48. Right-sizing digital innovation
Focused on cycle time optimization
Smaller teams and faster tools

49. Two-pizza teams
Silo-breaking

50. “Any organization that designs a
system (defined broadly) will
produce a design whose structure is
a copy of the organization's
communication structure.
Melvyn Conway, 1967

51. “When looking to split a large application into parts, often
management focuses on the technology layer, leading to UI
teams, server-side logic teams, and database teams.
When teams are separated along these lines, even simple
changes can lead to a cross-team project taking time and
budgetary approval.
A smart team will optimise around this and plump for the lesser of
two evils - just force the logic into whichever application they
have access to. Logic everywhere in other words.
This is an example of Conway's Law in action.”
Martin Fowler, “Microservices”

57. The people building the
infrastructure for the cloud need a
way to do continuous innovation.
Users need stability in their cloud
infrastructure to be able to do
continuous innovation.

58. Question 3:
What is happening with Cloud Foundry?

59. Cloud Foundry enables continuous deployment of
cloud native apps at scale.
Cloud Foundry runs in multiple clouds.

60. Currently shipping Cloud Foundry

62. We’re rebalancing the system towards user-
driven roadmaps and control of the upstream
project.
We’re building support for specific industry
clusters in Financial Services, Industrial IoT, and
Telecommunications.

63. We’re learning a ton about moving a project
from single-vendor open source to multi-vendor
open source.
Explicit controls
Implicit controls
Transparency
Communication

64. We’re focusing on certification to guarantee
portability of apps across clouds.
Make it lasting and durable.
Build the ecosystem of opportunity.

65. We see a world of cloud computing that is
UBIQUITOUS and FLEXIBLE
supporting public, private, and hybrid application environments.
PORTABLE and INTEROPERABLE
enabling users to move their applications wherever they need to go.
VIBRANT and GROWING
underlying a massive ecosystem of applications and developers
based on an efficient marketplace.

66. We see a human community that is
PRAGMATIC
and focused on exchanging practical experience.
DIVERSE
and inclusive of people across race, gender, orientation, and lifestyle.
RESPECTFUL
and committed to listening to thoughtful and honest perspectives.

67. Thank you
