Confidential “If you are doing quarterly releases and your competitor is doing daily releases you will fall so far behind” Adrian Cockcroft – former Netflix Architect

Cisco Confidential Gene Kim - author of “The Phoenix Project” and the “DevOps Handbook” “[DevOps is] a set of cultural norms and technical practices that enable this fast flow of work from dev through test through operations while preserving world class reliability”

Cisco Confidential Lean

Confidential • Organization can never have enough information to understand how to do better in the marketplace. • The more we experiment, the more information we can gather • Solid Information leads to improved strategy and benefits our customer as well as the business. Improve Ability to Respond and Shift

Confidential HOW ?

Cisco Confidential What is a Microservice? • A small and focused piece of software • Stateless loosely coupled • Language and technology independent • Highly scalable and fault tolerant

Cisco Confidential Application Evolution is Driving Technology Adoption

Cisco Confidential Better aligning to the Dev and Ops of DevOps • Puppet, Chef, Ansible are popular with Ops but not Devs • Containers are equally popular with both • Containers create a natural segmentation of effort • Devs inside the container, Ops outside the container The Impact of Containers on DevOps

Cisco Confidential • Guaranteed consistency for CI/CD • Simplified light weight image files • Only what the app needs and nothing else • What is built on a laptop will work the same in production • Open community built best of breed containers • Public container repository - Docker Hub • SPEED • Deploy in seconds instead of minutes The Impact of Containers on DevOps

Cisco Confidential Death Star

Cisco Confidential Microservice = LOTS of east west traffic

Confidential Intro CI/CD (DevOps tools of trades)

Confidential Sequential Design Approach Requirements and scope are fixed Waterfall Development Process

Confidential Before Agile Methodologies

Confidential Benefits of Agile Development

Confidential

Confidential • Place to store your current and past versions of code/configuration • Ability to merge, branch, fork • Ability to see who has changed which file • Highly available service • Ability to revert to prior versions • Public or Private / OnPrem / OffPrem • Source Code Management / Version Control System

Confidential Local Development

Confidential CI/CD

Confidential • Place to Store your Artefact (Docker images, bin, etc) • Public or Private / OnPrem / OffPrem Artefact Management

Confidential Infrastructure as Code Management of infrastructure (networks, virtual machines, load balancers, and connection topology) in a descriptive model, using the same versioning as DevOps team uses for source code

Confidential Monitoring, Logging, Alerting

Confidential • Integration with Development Environment • Code commits should appear • Chat with History • Team Rooms • Multi-Platform Clients • “Chat-Ops” Collaboration, Communication and Sharing

Confidential Cisco UCS Integrated Infrastructure for Containers

Confidential • Continuous Integration: Merging of development work with code base constantly so that automated testing can catch problems early • Continuous Delivery: Software package delivery mechanism for releasing code to staging for review and inspection • Continuous Deployment: Relies on CI and CD to automatically release code into production as soon as it is ready. Constant flow of new features into production Continuous Integration, Delivery, and Deployment

Confidential

Confidential What About Security? Must be inserted into the DevOps process (not a bolt on!)
