This document provides an overview of DevOps concepts and tools. It discusses containers and container orchestration with Kubernetes. It also mentions Azure DevOps and Azure Kubernetes Service (AKS) as tools that can help with DevOps practices like continuous integration/delivery (CI/CD). Helm charts are presented as a way to define and manage complex Kubernetes applications and services. Some best practices for Kubernetes are also listed.
7. developers
I need to create applications
at a competitive rate without
worrying about IT
New applications run smoothly
on my machine but malfunction
on traditional IT servers
My productivity and application
innovation become suspended
when I have to wait on IT
8. IT
I need to manage servers
and maintain compliance
with little disruption
I’m unsure of how to integrate
unfamiliar applications, and I
require help from developers
I’m unable to focus on both
server protection and
application compliance
12. People. Process. Products.
What is DevOps?
DevOps is the union of people,
process, and products to
enable continuous delivery of
value to your end users.

15. Why Containers?
Developers
Enable ‘write-once, run-anywhere’ apps
Enables microservice architectures
Great for dev/test of apps and services
Production realism
Growing Developer Community
Operations
Portability, Portability, Portability
Standardized development, QA, and prod
environments
Abstract differences in OS distributions
and underlying infrastructure
Higher compute density
Easily scale-up and scale-down in response
to changing business needs

Not a real thing. An application delivery mechanism with
process isolation based on several Linux kernel features.

An open source container runtime
Mac, Windows & Linux support
Command line tool
“Dockerfile” file format for building container
images
The Docker image format with layered filesystem

45. Helm
The best way to find, share, and use software
built for Kubernetes
Manage complexity
Charts can describe complex
apps; provide repeatable
app installs, and serve as a
single point of authority
Easy updates
Take the pain out
of updates with in-
place upgrades and
custom hooks
Simple sharing
Charts are easy to
version, share, and host
on public or private
servers
Rollbacks
Use helm rollback
to roll back to an older
version of a release
with ease

5 Kubernetes Best Practices
Jamie:
We’re going to be spending a lot of time taking about DevOps today. It would probably be a good idea to start of with what exactly we mean when we say DevOps.
Donovan, you’ve spent more time talking with folks about DevOps than anyone I know, what does DevOps mean to you?
Donovan:
DevOps is the union of people, process and products to enable the continuous delivery of value to your end customers
…
Jamie:
We know that DevOps tools & practices help folks ship faster.
The numbers in this slide are from the latest State of DevOps report.
On the surface these numbers can seem crazy.
But I have experienced them 1st hand.
10 years ago, 2 year ship cycles were the norm. If we shipped something to customers more than once a year it was a good year. Last week we shipped hundreds of changes, just in my team. & wow our developers happier when they don’t have to wait to ship what they’ve built.
It has completely been a DevOps transformation; our people have learned; and our processes and tools are better.

Today I’m very excited to announce Azure DevOps.
A set of services for developers that span the software lifecycle.
You can use them together or independently. It all depends on what you need.
Either way, I know they can help you ship faster.
How? Because they are what we use at Microsoft. In the last month over 80k folks here at MS have used Azure DevOps to ship our software to you.. Both the small teams & the large teams.
Transition…
Lets jump in & take a look at Azure DevOps, starting with Azure Pipelines.
(just Jamie)
The What…
Azure Pipelines is our offering for the heart of your DevOps needs… CI/CD… continuous integration & deployment.
Azure Pipelines is the perfect launchpad for your code – automating everything… from your builds and deployments so you spend less time with the nuts and bolts and more time being creative
At Microsoft we do just that. We deploy over 78k times a day with Azure Pipelines.
Open & extensible…
It’s great for any type of application, any platform or any cloud.
It has cloud hosted pools of Linux, Mac & Windows VMs that we manage for you.
Your not restricted to the functionality we provide, Pipelines has rich extensibility. Partners and the community can contribute extensions in our marketplace for everyone
One of my favourite things is when new extensions show up. We have over 500 today, ranging from community built to services from Slack to SonarCloud.
works has rich extensibility with a wide range of community extensions along with
If you want to build & test a Node app in a GitHub repo and deploy it via a docker container to AWS… go for it.
Containers / Modern…
Containers are becoming more & more the unity of deployment & Azure Pipelines is great for containers.
Azure Pipelines can build images, push them to container registries like Docker Hub and Azure Container Registry. You can deploy to any container host including Kubernetes.
Transition…
Donovan, is going to show us Azure Pipelines in action.
We use Azure DevOps at scale inside of Microsoft
We have been using these core services for years to build many of the products from Microsoft, from Windows to Office to Minecraft.
We do…
over 4m builds each month.
500m tests executed every day
Over 78k deployments every day.
Now Donovan is going to show us how we use Azure DevOps to build Azure DevOps
From Martin: We have been using these core services for years to build many of the products from Microsoft, from Windows to Office to Minecraft. At the moment we do on third of a million code reviews a month using pull requests in Azure Repos. Microsoft deploy OVER 78,000 times A DAY using Azure Pipelines.
