“Kubernetes is an open-source
platform designed to automate
deploying, scaling, and operating
application containers."
Initial release: 7 June 2014

Deploy k8s clusters, pods, and services!
Find modules: https://registry.terraform.io/
Providers include Azure & Azure Stack, as
well as other clouds.

aka.ms/k8slearning
Azure Kubernetes Service (AKS)

•allows serverless resources to join a
Kubernetes cluster

•serverless cloud container services
appear as virtual nodes via Virtual
Kubelet providers

•enables capacity on demand,
without delays or pre-provisioning

Run scriptable, automated tasks in the cloud — as part of
your Kubernetes cluster
Simple, powerful pipes
Each project gets a brigade.js
config file, which is where you
can write dynamic, interwoven
pipelines and tasks for your
Kubernetes cluster
Runs inside your cluster
By running Brigade as a
service inside your Kubernetes
cluster, you can harness the
power of millions of available
Docker images
brigade.sh

Spec for packaging distributed apps
CNAB: package distributed apps
CNABs facilitate the bundling,
installing and managing of
container-native apps — and
their coupled services
Cloud Native Application Bundle
cnab.io

Duffle
Install and manage distributed app bundles
Duffle: install & manage
distributed app bundles
Simple CLI to interact with
CNAB, for use with your
clouds and services of choice
duffle.sh

A friendlier cloud installer
Install your app and its baggage
Bundle up not just the app,
but everything it needs to run
in the cloud
Build bundles smarter, not harder
Use mixins for common tools
and clouds, and depend on
existing bundles.
Surprise! It does package
management too
Package and version your
bundle, then distribute it for
others to use.
porter.sh

- View & manage Kubernetes clusters

- Build & run containers from Dockerﬁles

- Intellisense for Kubernetes & Helm resources

- Works anywhere (Azure, Minikube, KIND, AWS, GCP, etc)

Service Mesh Interface
A Kubernetes interface that provides traffic
routing, traffic telemetry, and traffic policy
Apps Tooling Ecosystem
Standardized
Standard interface for  
service mesh on Kubernetes

Basic feature set to address
most common scenarios
