4. Azure Container Registry ACR
5. ACR § Private Docker registry based on Docker Registry 2.0 § Fully managed Azure Service § Seamless integration with Docker CLI § Available in three SKUs (Basic, Standard Premium) § Provides webhooks for further automation like Continuous Deployment (CD) Azure Container Registry
6. Feature Comparison Basic Standard Premium Storage 10 GB 100 GB 500 GB Max read Ops. per Minute 1.000 300.000 10.000.000 Max write Ops. per Minute 100 500 2.000 Max download bandwidth 30 MBps 60 MBps 100 MBps Max upload bandwidth 10 MBps 20 MBps 50 MBps Webhooks 2 10 100 Geo Replication Not supported Not supported In Preview ACR SKUs
7. Get access to your Azure Container Registry § Azure AD-based login mechanism for regular usage § Tokens requested by Azure CLI will be used to authenticate with ACR § Headless Authentication using Azure AD Service Principals § Used by Orchestrators or other Services § Admin Account § Designed for Single User scenarios § Should be disabled on all (pre)-production ACRs Authentication
8. DEMO ACR
9. Azure Web Apps for Containers
10. For Containers § Execute Web Apps based on Docker Images § Interaction with public and private Docker Registries § Frictionless Continuous Deployment § Port Forwarding configured automatically § Dockerfile EXPOSE Azure Web Apps
11. DEMO Web Apps for Containers
12. Azure Container Instances ACI
13. ACI § Run Docker images with a single command § No orchestration or administration required § Consume Docker images from Docker Hub or Azure Container Registry § Public IP connectivity § Persistent storage using Azure Files shares § Support for Windows and Linux Containers Azure Container Instances
14. How much is ACI ACI Pricing § Azure Container Instances § Payed per second and per created instance § Create requests + memory duration + core duration = total cost § Prices are shown for Azure region West Europe Price Create Container Instance 0,0022 € Container Instance duration Per CPU Core and second 0,0000102 € Per GB Memory and second 0,0000102 €
15. DEMO ACI
16. Azure Container Services AKS
17. 10.000 foot view Kubernetes architecture
18. 10.000 foot view Kubernetes architecture – With HA Master
19. 10.000 foot view Kubernetes architecture – With HA Master and ACI Connector
20. Including system namespace Namespaces
21. With Pods and Service Namespace
22. Without Labels Pods and Service
23. With single Container Pod
24. With Sidecar Container Pod
25. With LabelSelector and Labels Pods and Service
26. AKS § Fully managed Kubernetes cluster § Frictionless operation of containerized apps § Easy to scale-out, upgrade, replicate § Seamless integration with other Azure resources § Self healing for k8s Masters § Cost efficient – you pay for your Nodes Azure Container Services
27. AKS § Currently in technical preview (April 2018) § Preview is only available in the following Regions § East US, West Europe, Central US, Canada Central, Canada East § Service quotas and limits* § Max 100 nodes per cluster § Max 110 pods per node § Max 20 clusters per subscription * Due to preview, can be increased by creating an Azure Service Request Azure Container Services
28. Azure AKS § K8s Load Balancer will spin up an Azure Load Balancer § Easily mount Azure Files Shares and Disks as Volumes § Consume Docker Images from Azure Container Registry § Communicate with other Azure Resources like Redis, SQL Azure § Traffic inside the same region is always free AKS Azure Integration
29. ACI vs AKS vs Web Apps
30. When to use § Dynamic and isolated Workload § Single and atomic execution § No need for upgrades § No need for static IP addresses § Short execution times Azure Container Instances
31. When to use § Complex Applications § Orchestration requirements § Scale Out § No-Downtime upgrades Azure Container Services
32. When to use § No or few management / orchestration requirements § Great for simple (stateless) Web Applications § Applications that consist of a few artefacts § Use them when scale-out capabilities fit your requirements Azure Web Apps for Containers
33. Do the math! Use Azure Pricing Calculator and estimate a forecast
