12. What’s behind Kubernetes’ growth?
Kubernetes: the leading orchestrator shaping the future app development and management

13. How Kubernetes works
1. Kubernetes users communicate
with API server and apply
desired state
2. Master nodes actively enforce
desired state on worker nodes
3. Worker nodes support
communication between
containers
4. Worker nodes support
communication from the
Internet

serviceaccounts, etc.

14. Kubernetes on its own is not enough
Save time from infrastructure management and roll out updates faster without compromising security
Unlock the agility for containerized
applications using:
• Infrastructure automation that simplifies
provisioning, patching, and upgrading
• Tools for containerized app development
and CI/CD workflows
• Services that support security, governance,
and identity and access management

16. Manage Kubernetes with ease
• Automated provisioning,
upgrades, patches
• High reliability, availability
• Easy, secure cluster scaling
• Self-healing
• API server monitoring
• At no charge (you don’t pay the
managed control plane)

19. Accelerate containerized development
Kubernetes and DevOps
better together
Develop
• Native containers and Kubernetes support in IDE
• Remote debugging and iteration for multi-
containers
• Effective code merge
• Automatic containerization
Deliver
• CI/CD pipeline with automated tasks in a few
clicks
• Pre-configured canary deployment strategy
• In depth build and delivery process review and
integration testing
• Private registry with Helm support
Operate
• Out-of-box control plane telemetry, log
aggregation, and container health
• Declarative resource management
• Auto scaling

20. Azure makes Kubernetes easy
Deploy and manage Kubernetes with ease
Task The Old Way With Azure
Create a cluster Provision network and VMs
Install dozens of system components including etcd
Create and install certificates
Register agent nodes with control plane
az aks create
Upgrade a cluster Upgrade your master nodes
Cordon/drain and upgrade worker nodes individually
az aks upgrade
Scale a cluster Provision new VMs
Install system components
Register nodes with API server
az aks scale

21. Azure makes Kubernetes easy
Roll out new features seamlessly (CI/CD)
Task The Old Way With Azure
Set up a CI/CD pipeline and
deploy to Kubernetes
Create Git repo
Create a build pipeline
Create a container registry
Create a Kubernetes cluster
Configure build pipeline to push to container registry
Configure build pipeline to deploy to Kubernetes
Define and set up deployment strategy
Create a project on Azure DevOps with Kubernetes/AKS as a
target
Make container images
available for deployment
worldwide
Create a container registry in every region
Configure build pipeline with multiple endpoints
Loop through all regions and push following build
Create an Azure Container Registry with geo-replication
Push your image to a single endpoint
Track health with
consolidated cluster and
application logs
Choose a logging solution
Deploy log stack in your cluster or provision a service
Configure and deploy a logging agent onto all nodes

anywhere
Azure Arc is a set of technologies that extends Azure management and
enables Azure services to run across on-premises, multi-cloud, and edge

27. Azure Arc-enabled
Kubernetes clusters
• Central inventory and monitoring of the
sprawling assets running anywhere from
on-premises to edge
• Consistently apply policies, role-based-
access-controls (RBAC) for at-scale
governance
• Deploy Kubernetes resources to all
clusters using a GitOps-based workflow
