  1. Supporting the Comcast Cloud Warren Wang, Andrew Mitry, Bill Hathaway, and Mark Muehl Moderated by Lew Tucker @ Cisco March 25, 2013

  2. Selling the Cloud • “What’s OpenStack?” • Idea to build a cloud based on OpenStack started over a year ago • Build it and they will come • Had to introduce and campaign OpenStack to engineering and development teams • Many teams managing their own infrastructure stacks • What if? • Reduced time to market • Concentrate on applications, not hardware • Fewer network connectivity issues • Distributed compute and storage easily available Show it off • Demos are effective for this Supporting the Comcast Cloud

  3. Rethinking Application Design • BFF! • Design applications which scale horizontally, and are fault tolerant • Ephemeral storage and object storage only • Heavy orchestration and automation • Designed to work in cloud environment • Let’s talk • Databases and other applications which require persistent storage • Resource heavy applications using MaaS • Image based deployments I know someone, here’s a number to call • Monolithic database • Multiple single points of failure • Old OS • Deployment plan is a 100 page document Supporting the Comcast Cloud

  4. What Comcast is building • Our vision • Unified environment to build & operate our most critical & innovative initiatives • Provide technical agility, efficiency, and velocity to our business • Reinforce and capitalize on scaled design principles • Deployments up or in-process today • Starting in our national data centers • Few thousand cores, 10s of TB RAM; 100s of TB of replicated storage (object & block) • Development, lab & production • Distributed data centers • Desire to scale to hundreds of “cells” as we move deeper in the network closer to the customer • Distributed compute / storage / network fabric to support elastic scale • Clean slate – free of legacy requirements • OpenStack is the virtualization & scheduling layer to stitch this together Supporting the Comcast Cloud

  5. Why OpenStack • Widely adopted across diverse workloads • Our problems are not the hardest problems on the planet • We can learn a great deal engaging in a broader technical community • And we have a little bit to share too • Vibrant and diverse development community • New features quickly • Reliable implementation • Receptive to broad and deep participation – even from heavyweights • Explicitly want to avoid vendor lock-in • Abstraction, composability and orchestration are key • Makes underlying hardware more fungible • Intelligent resource scheduling – understood by the app but managed by OpenStack • Effective separation of concerns (e.g. data replication in the data layer) • Encourages improved software design practices Supporting the Comcast Cloud

  6. What Comcast is building • Separation of application development from underlying infrastructure services • PaaS (Platform as a Service) • IaaS (Infrastructure as a Service) • MaaS (Metal as a Service) • Seeking harmony among apps, cloud infrastructure, and network • Balance cost, reliability, scalability and security • Simplify & better utilize the network, storage, and compute (app knows best) • Move security & connectivity policy deeper into application control Supporting the Comcast Cloud
