14 SEPTEMBRE 2023 IT in the 90s Once upon a time…
In a time almost forgotten When even internet was young…
When Windows 95 was the cutting edge And a 100 Mb disk was huge…
Big companies still used mainframes Bigger, fancier, but still the same old IBM
Bare-metal based IT reigned Control, reliability, security… But cost, rigidity, logistics…
Applying the industrial model Trying to shoehorn IT into a model where it doesn’t fit
Walls & Silos And procedures, and hierarchy, and corporate politics
14 SEPTEMBRE 2023 Tooling evolves CVS, Ant and (Leeeroy) Jenkins
Old school procedures
Tooling empowering changes Theory existed since 1999 But without the right tooling…
Source control tools Better than copying and renaming folders…
Dependency management & build Better than grabbing each dependency in their website and running javac by hand…
Unit testing and continuous integration Hudson CI If Testing is Doubting, let’s doubt automatically
Monitoring tools No more spending nights looking at a status screen
Too many changes in a few years Old ways were difficult to change
14 SEPTEMBRE 2023 XP, agility and DevOps Buzzwords that changed the IT
Extreme Programming
Manifesto for Agile Software Development
Breaching walks, breaking down silos
The business of Agility The Dark Side rises
Agile Tooling
Back to industrial practices ?
Is DevOps the same than Agility? Can you have one without the other?
You could have Agility without DevOps Even if I fail to see why you would want…
DevOps is a reaction to the wall of confusion Making the different stakeholders to work together in sync
You cannot have DevOps without agility DevOps is about shorter development sprints, increased focus on testing, increasing automation
DevOps comes with Agility DevOps is an extension of Agile that includes systems and operations
14 SEPTEMBRE 2023 Enter the Cloud Renting server time in other’s people infra
From virtualisation to the cloud How to use the infrastructure at its full capacity
The five pillars of the Cloud
Cloud demands automation
It changes the way how IT works And it demands a mentality change
Empowering developers Infrastructure is only a click away
Distributed is the new black Cloud Native architectures and services
Sysadmins who code Creating tools: automation, monitoring, observability…
New roles appear: SRE WTF is a System Reliability Engineer?
14 SEPTEMBRE 2023 Declarative Infrastructure The intern metaphor
Containers make dev life easier
Less simple if you must operate them Like in a production context
And what about microservices? Are you sure you want to operate them by hand?
And what about microservices? Are you sure you want to operate them by hand?
Kubernetes: a full orchestrator
Kubernetes - Desired State Management
Terraform - Declarative infra as code
14 SEPTEMBRE 2023 GitOps And other alternatives (why not KafkaOps?)
Continuous Integration(CI) & Continuous Delivery (CD) Build Test Security Checks Continuous Integration Continuous Delivery Release Deploy Stage Deploy Prod
A central source of truth
What is GitOps? Git is the single source of truth Treat everything as code Operations through Git workflows
14 SEPTEMBRE 2023 Platform What is it? Why is it useful? Why do we need Platform Engineers?
A fancy name for something already there Most companies already have some kind of platform Often homemade…
So many options …
So many options …
Shift left and Cognitive Load
Managing the self-service commodity
“The discipline of designing and building toolchains and workflows that enable self-service capabilities for software engineering organizations in the cloud-native era. Platform engineers provide an integrated product most often referred to as an “Internal Developer Platform” covering the operational necessities of the entire lifecycle of an application.” Lucas Galante
IDP is the new Facade Pattern
Team Topologies “Organizations that consider establishing such a platform team should be very cautious not to accidentally create a separate DevOps team, nor should they simply relabel their existing hosting and operations structure as a platform.” TechRadar, October 2021
Team Topologies Stream-aligned team Enabling team Complicated Subsystem team Platform team
Platform as a Product The Internal Dev Platform is the Product ● Conduct user research ○ Run friction logs ○ Empathy meetings ● Create a roadmap ● …
14 SEPTEMBRE 2023 Build your own Platform And becoming Platform Engineer
How to glue those all together ?
Kubernetes Operators A Kubernetes version of the human operator
Building operators Basic K8s elements: Controllers and Custom Resources
Extending Kubernetes API By defining new types of resources
A reconcile loop Strives to reconcile current state and desired state
