- The document discusses how user needs have changed with the rise of on-demand services, mobile usage, and the importance of delivering value through software. This has implications for both businesses and developers. - For developers, the key requirements are self-service, agility, flexibility, and delivering value through software. Technologies like containers, microservices, and orchestration tools help meet these requirements and enable cloud native applications. - Weaveworks was created to provide plumbing for cloud native applications by making them simple, portable, and transparent for developers without requiring app code changes.

Our North Star is to win more of our
members’ “moments of truth”

21. Our North Star is to win more of our members’ “moments of truth”.
Those decision moments are, say, on Thursday 7:15 pm or Monday 2:40 am when our
member wants to relax, enjoy a shared experience with friends and family, or is just
bored. They could play a video game, surf the web, read a magazine, channel surf
their MVPD/DVR system, buy a pay-per-view movie, put on a DVD, turn on Hulu or
Amazon Prime, or they could tap on Netflix. We want our members to choose Netflix
in these moments of truth.
We win those moments of truth when members expect, based on their prior
experience with us, that Netflix will be pleasurable, compared to all those other
options. The pleasure comes from our simple experience for choosing, control over
when to start/pause/resume the video, and from content that suits their taste and
their mood.
When we deliver enjoyment, members watch more Netflix, continue their
membership, and evangelize Netflix to their friends.

23. 2015 – Netflix has 60M+ subscribers, adding >4M per quarter

24. Implications for everyone else?

28. Key takeaways so far
• On demand services, powered by
software, are the new MUST HAVE
• And they are core to your business –
cannot be outsourced
• Businesses: ally with developers or die

30. The Technology
What developers need to know

31. 2015 “must have” requirements
•Self Service
•Agile & Always On
•Flexible Deployment

32. Implications of Self Service
• 1-click install & uninstall
• Pay per use, never pay to set up & provision
• Global scale & customer base
• Measure everything
• Test & adapt & upgrade in real time
 PROFIT!
For Developers – customer “me want it NOW”

33. Best way of think about this? App Store

34. Agile +
Always On

DevOps

35. DevOps Example
• Target, talk at DevOps enterprise summit, 2014
• Release frequency UP 100x
– 1/quarter  100/quarter
• Release size DOWN - 100x
• Errors and production issues DOWN by 90%
• Costs DOWN by 50%
For developers:
• Same team, much less waste, better products, happier
customers, continuous delivery..

Business value – better to spend
$100M on making House of Cards,
than on building a data center

38. Flexible Deployment
• Cloud
• Global infra for metered on demand services
• Super scalable, Ideal for DevOps, “Always On”, CI
Implication for developers
• Basically a RANDOM environment
• Can your app pass the 20% test?
• Can your app monitor & measure everything?

41. Key Takeaways so far!
• Developers:
– Optimize for speed instead of cost
– Assume that cloud is random
• This applies to:
– What you design
– How you develop
– Where you deploy
In the Moment of Truth, the customer doesn’t care about you,
they care about “me”

43. Not just Netflix, also:
GOOGLE

44. Google Scale for all?
• 2 billion containers started per week
• 100 billion per year
• Google has ~1% of world’s servers
Current potential of 100*100B = 10 trillion
server side containers per year globally
But there are 10-50M developers

45. Automation

46. Choice

47. Composable

48. Developing in the ‘me’ generation
• Google shows we need automation to scale
• Developers tell us they need choice
• Reject “one size fits all”. Embrace “composable”
 Cloud Native

49. Cloud Native Apps
Container packaged
Dynamically Scheduled
Micro-services oriented

50. Cloud Native Apps
In a nutshell: everything is decoupled for scale
Decouple software from physical deployment
Decouple users from service instances
Decouple software into components

51. Containers!
Fast, Easy, Portable Packaging
• Lightweight VMs – mobile & isolated env.
• Enables portability & idempotency
• More efficient than VMs – “lean and fast”
• Docker adds “make it easy for developers”

52. What is Docker?

53. Docker at the Moment of Truth
• Jason Hoffman:
– I think Linux took off because of package
management. I think that’s basically it. Docker’s
taking off because it’s the new package
management. It’s just that simple.

54. Convenience

55. Safety?

56. Managing Docker in enterprise
• Performance Management
• Security
• Monitoring
• Provenance
• Policy
 It’s in the (weave) works

57. Dynamically Scheduled & Metered
• Mesosphere
• Kubernetes & GKE
• Docker Swarm
• Cloud Foundry Diego / LatticeCF
• Amazon ECS
• Azure?
 WSO2 Stratos uses Kubernetes, so does Fabric8,
so does OpenShift…

58. Microservices

66. Summary
• User needs have changed
• Business needs lots more developers
• Cloud Native is the way forward

67. Adapt or …
