What is Kubernetes in Azure?
Kubernetes is a fast-growing platform for managing containerized applications, storage, and networking components. It allows developers and administrators to focus on application workloads, not infrastructure components. Kubernetes provides a convenient, declarative way to deploy large numbers of containers, with a powerful set of APIs for management tasks.
Kubernetes can be complex to install and maintain, especially when running in production and at an enterprise scale. To reduce the complexity of key management and deployment operations, such as scalability and Kubernetes updates, you can use Azure Kubernetes Service (AKS), which offers managed Kubernetes services.
To simplify the process, Azure manages the AKS control plane, and customers pay only for the AKS nodes the application runs on. AKS is based on the Azure Kubernetes Service Engine, which was released by Microsoft as open source.
This is part of an extensive series of guides about https IaaS.
Azure Kubernetes: Reference Architecture
To illustrate how Kubernetes is typically implemented on Azure, Microsoft provides a reference architecture, which is a Microsoft application implemented in Azure Kubernetes Service (AKS). This reference architecture can be a starting point for most implementations.
The reference architecture is composed of:
Kubernetes on Azure: Tools and Services
Azure Kubernetes Service
The Azure Kubernetes Service (AKS) facilitates the deployment of managed Kubernetes clusters in Azure. AKS offloads critical tasks from developers and administrators, such as health monitoring and maintenance.
When running on AKS, you only need to manage agent nodes, and pay only for agent nodes. There is no charge for Kubernetes master nodes—these are configured and deployed automatically. You can configure other features, including Azure AD integration, advanced networking, and monitoring.
You can use the Azure CLI, or the Azure Portal, to create AKS clusters. Another option is to use infrastructure as code (IaC) solutions like Azure Resource Manager templates or TerraForm.
Azure Container Instances
Containers are becoming the preferred means of packaging, deploying and managing cloud applications. Azure Container Instances provide a convenient way to manage containers in Azure, without managing virtual machines. Container instances start in seconds, because they have much less overhead than Azure VMs.
You can import images of Linux or Windows containers from DockerHub, your personal Azure Container Registry, or any other Docker registry. Azure Container Instances has a cache of popular images of base operating systems, helping you deploy custom images faster.
Azure Service Fabric
Service Fabric offers a distributed platform that lets you package and deploy microservices applications composed of containers. Service Fabric addresses many of the major challenges of cloud native development.
Azure Service Fabric focuses on building stateful services. You can take advantage of the service framework programming model, or run containerized services with stateful requirements, using the language or code of your choice. You can also create Service Fabric clusters on local Linux machines, Windows Server, or other public cloud platforms.
Service Fabric is used to power many core Microsoft services, including Microsoft Power BI, Azure SQL Database, Cosmos DB, Dynamics 365, and Skype.
Azure Container Registry
Azure Container Registry (ACR) is a privately hosted Docker registry service, built on the open source Docker Registry 2.0. Create and manage Azure container registries to store and manage your organization’s private Docker images.
You can also use ACR Tasks to build containers on demand from images, automate your builds according to events like commits to your source code repository, or updates to base images.
Azure Dev Spaces
The Azure Dev Spaces service provides a fast, iterative Kubernetes development environment for teams using AKS. Azure Dev Spaces allows you to troubleshoot and test all application components in AKS, without needing to set up development machines or setting up dependencies.
With Azure Dev Spaces you can automatically generate Docker and Kubernetes artifacts for a project, making it easy to add new and existing Kubernetes applications to a development effort.
Kubernetes in Azure with Cloud Volumes ONTAP
NetApp Cloud Volumes ONTAP, the leading enterprise-grade storage management solution, delivers secure, proven storage management services on AWS, Azure and Google Cloud. Cloud Volumes ONTAP capacity can scale into the petabytes, and it supports various use cases such as file services, databases, DevOps or any other enterprise workload, with a strong set of features including high availability, data protection, storage efficiencies, Kubernetes integration, and more.
In particular, Cloud Volumes ONTAP supports Kubernetes Persistent Volume provisioning and management requirements of containerized workloads.
