WERT IS DERVERPS SCOPE ▸ Introductions ▸ What is Dev Ops, Why do I care? ▸ Virtualisation, Containerisation and Bare Metal ▸ IaaS, PaaS and 'The Cloud' ▸ Tools for DevOps-ers ▸ Continuous Delivery and Source Controlled Deployments ▸ Examples ▸ Bigpipe (Spark Venturs) ▸ Healthlink
WERT IS DERVERPS WHAT IS DEVOPS? WHY DO I CARE? ▸ DevOps (a clipped compound of "development" and "operations") is a culture, movement or practice that emphasises the collaboration and communication of both software developers and other IT professionals while automating the process of software delivery and infrastructure changes. It aims at establishing a culture and environment where building, testing, and releasing software, can happen rapidly, frequently, and more reliably. ▸ Wikipedia - https://en.wikipedia.org/wiki/DevOps
WERT IS DERVERPS WHAT IS DEVOPS? WHY DO I CARE? ▸ Translation: ▸ Dev Ops is about the breaking down of walls between Code Developers, Code Testers and Code Operators
WERT IS DERVERPS VIRTUALISATION, CONTAINERISATION AND BARE METAL 1995: Monolithic EVERYTHING MONOLITHIC HARDWARE OS, RUNTIME, MIDDLEWARE THICK APP, THICK CLIENT Runescape Ubuntu Server 8.4 (Current was 12.4), JVM Bare metal servers - add more servers to scale
WERT IS DERVERPS VIRTUALISATION, CONTAINERISATION AND BARE METAL Later: Virtual Machines VM SERVER HOST OS HYPERVISOR GUEST OS BIN / LIB APP A GUEST OS BIN / LIB APP B GUEST OS BIN / LIB APP C
WERT IS DERVERPS VIRTUALISATION, CONTAINERISATION AND BARE METAL 2014: Containers Arrive SERVER HOST OS BIN / LIB Container BIN / LIB APP A APP B APP C APP S DOCKER
WERT IS DERVERPS THE CLOUD ▸ Cloud Infrastructure vs Local Infrastructure...or Hybrid? ▸ Popularised by the Silicon Valley SaaS startup 'cult' ▸ Main argument for Cloud Infra is OPEX rather than CAPEX
WERT IS DERVERPS THE CLOUD: A QUICK PROVIDER OVERVIEW ▸ Expensive ▸ Not as capable as AWS, fewer supporting services ▸ Like seriously.. are their SSDs made of gold or something?? ▸ Better dashboard then AWS (IMO)
WERT IS DERVERPS THE CLOUD: A QUICK PROVIDER OVERVIEW ▸ Dyno based pricing (Dyno is a compute unit) ▸ Extremely slow response time if no dyno already running (web scale) ▸ Good starter kits for experimentation
WERT IS DERVERPS TOOLS FOR DEVOPS-ERS ▸ DevOps covers the whole SDLC so technically any tool can be used in a DevOps fashion, it's about the process rather than the specific tool ▸ ALTHOUGH there are a bunch of awesome tools! ▸ https://github.com/sindresorhus/awesome ▸ http://newrelic.com/devops/toolset ▸ http://devops.com/2015/08/07/9-open-source-devops- tools-love/
WERT IS DERVERPS CONTINUOUS DELIVERY AND SOURCE CONTROLLED DEPLOYMENTS ▸ Infrastructure as a Service ▸ Infrastructure as Code ▸ Great Tools specifically for automated deployments, orchestration and configuration management
WERT IS DERVERPS CONTINUOUS DELIVERY AND SOURCE CONTROLLED DEPLOYMENTS ▸ Ruby based DSL ▸ Declarative ▸ Agents interact with a master ▸ New Console sexy AF ▸ ~$100 x node x year ▸ https://puppetlabs.com
WERT IS DERVERPS CONTINUOUS DELIVERY AND SOURCE CONTROLLED DEPLOYMENTS ▸ More flexible pricing ▸ ~($72 || $127) x node x year ▸ Less tightly defined Ruby based DSL ▸ https://www.chef.io
WERT IS DERVERPS CONTINUOUS DELIVERY AND SOURCE CONTROLLED DEPLOYMENTS ▸ Python based - really interesting ▸ Really new - less proven then Puppet or Chef ▸ Couldn't find price on website so makes me suspicious ▸ http://saltstack.com/
WERT IS DERVERPS CONTINUOUS DELIVERY AND SOURCE CONTROLLED DEPLOYMENTS ▸ Uses YAML templating language ▸ Advertised as super simple ▸ Uses SSH for EVERYTHING ▸ Seems really janky ▸ DISCLAIMER - have never used it ▸ Cheaper then puppet and chef ▸ https://www.ansible.com
WERT IS DERVERPS SPARK VENTURES EXAMPLE ▸ SaaS Products ▸ Lightbox && Qrious most demanding ▸ Morepork and Bigpipe have CD ▸ Not a true devops workplace, not moving to it either
WERT IS DERVERPS HEALTHLINK EXAMPLE ▸ Early Stages of Tech Modernisation ▸ Puppet deployment underway ▸ Technical Debt and Legacy Code is huge ▸ Moving towards true devops
