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

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 Neglix. We want our members to choose Neglix in these moments of truth. We win those moments of truth when members expect, based on their prior experience with us, that Neglix will be pleasurable, compared to all those other op)ons. 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 Neglix, con)nue their membership, and evangelize Neglix to their friends.

2015 – NeClix has 60M+ subscribers, adding >4M per quarter

Implica)ons for everyone else?

Key takeaways so far

•  On demand services, powered by soXware, are the new MUST HAVE

•  And they are core to your business – cannot be outsourced

•  Businesses: ally with developers or die

The Technology

What developers need to know

2015 “must have” requirements

• Self Service • Agile & Always On • Flexible Deployment

Implica)ons 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 )me à  PROFIT!

For Developers – customer “me want it NOW”

Best way of think about this? App Store

Agile + Always On à DevOps

DevOps Example •  Target, talk at DevOps enterprise summit, 2014

•  Release frequency UP 100x –  1/quarter à 100/quarter

•  Release size DOWN -‐ 100x •  Errors and produc)on issues DOWN by 90% •  Costs DOWN by 50%

For developers: •  Same team, much less waste, beYer products, happier customers, con)nuous delivery..

Take the DevOps test

1.  Can you redeploy your en)re applica)on in minutes? 2.  Does your applica)on depend on specific IP addresses, ports, file

systems, that are not part of the automated installa)on? 3.  Can your applica)on survive, and auto-‐recover from, infrastructure

(compute, network, storage) failures? 4.  Can you upgrade and downgrade, your applica)on (or parts of the

applica)on) without any impact to users? 5.  Can you run mul)ple versions of your applica)on services, in the same

environment at the same )me? 6.  Can you safely test in produc)on? 7.  If a part of an applica)on fails, will other parts con)nue to operate? 8.  Can parts of your applica)on scale-‐up and scale-‐down automa)cally,

based on user load or other factors? 9.  Can you deploy applica)on components across cloud providers? 10.  Can you deploy an applica)on component on a different cloud provider?

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

Flexible Deployment

•  Cloud •  Global infra for metered on demand services •  Super scalable, Ideal for DevOps, “Always On”, CI

Implica)on for developers •  Basically a RANDOM environment •  Can your app pass the 20% test? •  Can your app monitor & measure everything?

Key Takeaways so far!

•  Developers: –  Op)mize 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”

Not just Neglix, also:

GOOGLE

Google Scale for all?

•  2 billion containers started per week •  100 billion per year •  Google has ~1% of world’s servers

à Current poten)al of 100*100B = 10 trillion server side containers per year globally

à But there are 10-‐50M developers

AutomaPon

Choice

Composable

Developing in the ‘me’ genera)on

•  Google shows we need automa)on to scale •  Developers tell us they need choice •  Reject “one size fits all”. Embrace “composable”

à Cloud Na)ve

Cloud Na)ve Apps

Container packaged Dynamically Scheduled Micro-‐services oriented

Cloud Na)ve Apps

In a nutshell: everything is decoupled for scale Decouple soXware from physical deployment Decouple users from service instances Decouple soXware into components

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”

What is Docker?

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.

Convenience

Safety?

Managing Docker in enterprise

•  Performance Management •  Security •  Monitoring •  Provenance •  Policy

à It’s in the (weave) works

Dynamically Scheduled & Metered

•  Mesosphere •  Kubernetes & GKE •  Docker Swarm •  Cloud Foundry Diego / LazceCF •  Amazon ECS •  Azure?

à WSO2 Stratos uses Kubernetes, so does Fabric8, so does OpenShiX…

Microservices

All Hail Adrian CockroU hYp://www.slideshare.net/adriancockcroX/dockercon-‐state-‐of-‐the-‐art-‐in-‐microservices

Summary

• User needs have changed •  Business needs lots more developers •  Cloud Na)ve is the way forward

Adapt or …

So why I am doing Weave?

Plumbing for cloud na)ve applica)ons

•  Simple, Portable, Transparent •  Cloud Na)ve apps made easy for developers •  NO need to rewrite app code or re-‐tool apps!
