Transcript

1. DEVOPS: THE GOOD PARTS ALEX CORKIN, HEALTHLINK
2. 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
3. WERT IS DERVERPS INTRODUCTIONS ▸ Alex Corkin ▸ Twitter: https://twitter.com/4lexNZ ▸ Github: https://github.com/ AlexanderNZ/ ▸ Web: http://4lex.nz ▸ SoT 2014 - Current ▸ Spark Ventures ▸ Healthlink NZ
4. 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
5. 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
6. WERT IS DERVERPS VIRTUALISATION, CONTAINERISATION AND BARE METAL
7. 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
8. WERT IS DERVERPS VIRTUALISATION, CONTAINERISATION AND BARE METAL 1995: Monolithic EVERYTHING SERVER DATABASE RUNTIME APPLICATION Server
9. 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
10. 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
11. WERT IS DERVERPS IAAS AND PAAS - DA F ARE ALL THESE ACRONYMS FOR Wikipedia - https://en.wikipedia.org/wiki/Cloud_computing
12. 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
13. WERT IS DERVERPS THE CLOUD: A QUICK PROVIDER OVERVIEW ▸ Excellent Free Trial ▸ 12 Months of Free t2.micro instance ▸ Loads of support ▸ Excellent supporting products (EC2, S3, Lambda, CodeDeploy etc)
14. 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)
15. 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
16. WERT IS DERVERPS THE CLOUD: A QUICK PROVIDER OVERVIEW: HONOURABLE MENTIONS Bunch of other application specific providers
17. 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/
18. 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
19. 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
20. 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
21. 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/
22. 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
23. WERT IS DERVERPS CLOUD PROVIDERS ▸ Walk through
24. SPARK VENTURES EXAMPLES
25. 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
26. HEALTHLINK EXAMPLES
27. WERT IS DERVERPS HEALTHLINK EXAMPLE ▸ Early Stages of Tech Modernisation ▸ Puppet deployment underway ▸ Technical Debt and Legacy Code is huge ▸ Moving towards true devops
28. THE END QUESTIONS?
