- 8. Some quote about importance of understanding something philosophically By me
- 9. What is the Internet? Beep boop beep … bop beep … ?
- 10. A (global) bunch of devices that talk to each other, with some infrastructure to support it. Seriously, that’s about it.
- 11. The Lower Internet Hierarchy Tier 3 Network Tier 3 Network PSTN PSTN PABX Router Ethernet Metro-fiber Cable Operator Dial-up customer POTS ADSL2 DSLAM Central Office Cable customer ADSL customer (Triple play) ADSL customer Leased line (T3/E3) Leased line (T1/E1) Cable plant ADSL Filter Filter Filter Internet

- 14. A Brief History of the Internet When computers started to talk to each other
- 15. The origin of the Internet Like many projects (like GPS) ●The internet started as a military / scientific project ●ARPAnet (Advanced Research Projects Agency Network) ●NSFNET (the National Science Foundation Network) was an early open network to share data
- 16. Robert Elliot Kahn a.k.a. Bob Khan, Inventor of Internet #1 • Completed an early version of TCP in 1973 & co-founded the Internet Society in 1992

- 19. DevOps, why? From multiple perspectives Data Consumption Adoption Rate Funding / Earnings Team Priorities
- 20. Current Trends (also known as “Problem Statement #1”)
- 21. The increase of adoption rate
- 22. More and more people are using the Internet… Source: domo.com
- 23. …especially during the pandemic
- 24. In 2020… Every minute.. • 500 hours of content to YouTube • $ 1M USD spent online • 347k stories on Instagram • 147k pictures to Facebook Source: domo.com
- 25. Every day..
- 26. All these stored in..

- 29. Fun fact: Source: The Two High-Growth Sectors That Could Outperform Tech [visualcapitalist.com]
- 31. What can we conclude from these? ●Data consumption & creation is growing at an exponential rate. ●Organizations must be quick to deploy solutions, or risk getting replaced by competitors. ●You must fail fast, fail more and recover fast. ●Data is the new gold. ●More and more money is being pumped into the tech sector.
- 32. Full Stack Development What do we mean when we say “Full Stack”? And also.. “Problem Statement #2”
- 34. From frontend to backend and beyond* * Depending on salary
- 35. “Operations” vs “Development” Teams And the bad blood between them And “Problem Statement #3”
- 36. A typical IT department
- 37. The Bad Blood
- 38. How Dev sees Ops
- 39. What does operations do? Architectural Engineering 8% Deployment Management 31% Incident Management 20% Problem Engineering 10% Overhead 11% Requests 6% Software Development 7% Site Management 7% Source: Study from Deepak Patil [Microsoft Global Foundation Services], 2006
- 40. How Ops sees Dev
- 41. What happens when change is required? Operations Development Architecture Quality Assurance (QA) Boss
- 42. The old and hard “waterfall model”
- 43. In short, Dev vs Ops ‘s Priority: Developers ●Maximize change (get products to market as soon as possible) ●Deploy code everywhere ●Use the latest and shiniest technology ●Freedom!! ●Uses the “development” / “R&D” budget ●Optimize for stability (the less change the better!) ●Set Control & Standards ●Less regulatory pressure ●Reduce surprises ●Uses the “run” / “operations” budget Operation
- 44. The Advent of DevOps And how the “agile” movement started
- 45. DevOps is a methodology that help both developers and operators reach their goals while maximizing quality & value delivery to the users. TLDR: Maximize value delivery in a short time, while maintaining quality
- 46. Essential Principles of DevOps 1. Infrastructure as Code (IaC) 2. Continuous Integration / Delivery (CI/CD) 3. Culture of Collaboration
- 47. Infrastructure as Code (IaC) Issues at hand ●Humans make mistakes ●The more the commands, the higher the rate of failure
- 48. { "Parameters": { "RootDomainName": { "Description": "Domain name for your website (example.com)", "Type": "String" } }, "Resources": { "RootBucket": { "Type": "AWS::S3::Bucket", "Properties": { "BucketName" : {"Ref":"RootDomainName"}, "AccessControl": "PublicRead", "WebsiteConfiguration": { "IndexDocument":"index.html", "ErrorDocument":"404.html" }... IaC Example
- 49. Infrastructure as Code (IaC) ●Automate provisioning ●Speed up deployments ●Make them repeatable & reliable ●Make sure standards are respected ●Time to Recovery ●Allow Devs to do tasks themselves!
- 50. Continuous Integration / Delivery (CI/CD) Key Ideas. The more you deploy: ●The more you master the art of deployment ●The smaller the changeset ●The better the Time to Repair / Resolution (TTR)
- 51. If it hurts, do it more often ! The DevOps credo
- 52. Zero Downtime Deployments Get feedback while maintaining continuity 1. Feature Flipping 2. Dark Launch 3. Blue / Green Deployments 4. Canary Release

- 60. “Sec” in DevSecOps Very briefly
- 61. “Sec” in DevSecOps A real-world sample – GitHub Actions Source: https://github.com/johannesjo/super-productivity/
- 62. The Future (?)
- 63. A Little Conclusion…. Phew! So much information to process in a day!
- 64. Takeaway Points ●DevOps is a methodology ●The Internet is growing bigger by the second, taking data consumption with it ●The industry needs to grow fast to stay relevant. To do that, they need to fail more, fail fast. ●Dev and Ops need to work together ●Humans are prone to error, remove them as much as possible.
