What is Kubernetes ?
Kubernetes is just a container management tool or container orchestration tool if one may say. Containers are small units/processes that are ran by kernel and are used to run majorly single application. We can say that container is a light weight OS that one can run on top of either bare metal OS or virtual machine instance. Container gives every application a sense of isolation since in one container we can only run on application or mostly preferred to run one application like, let’s say — webserver. Containers are a standardized unit of software that allows developers to isolate their app from its environment. Container is OS level virtualization.
Now there are many container tools available and one of which is docker. Docker is a software platform that allows you to build, test, and deploy applications quickly. Docker packages software into standardized units called containers that have everything the software needs to run including libraries, system tools, code, and runtime.
The only problem with docker is that it does not provide a service of monitoring and managing docker. Like if a container goes down than developer has to manually relaunch that container. So we need some kind of management software that manages the container. And Kubernetes ( k8s ) is the one. K8s behind the scene contacts docker to launch the container as developer needs and keeps track of that container. K8s works in cluster.
What is Azure Kubernetes Service?
Microsoft Azure is a world-renown cloud platform for SMBs to large scale business, while Kubernetes is a modern-day approach that is rapidly becoming the regular methodology to manage cloud-native applications in a production environment. Azure Kubernetes Service (AKS) has brought both solutions together that allow customers to create fully-managed Kubernetes clusters quickly and easily.
AKS is an open-source fully managed container orchestration service that became available in June 2018 and is available on the Microsoft Azure public cloud that can be used to deploy, scale and manage Docker containers and container-based applications in a cluster environment.
Azure Kubernetes Service offers provisioning, scaling, and upgrades of resources as per requirement or demand without any downtime in the Kubernetes cluster and the best thing about AKS is that you don’t require deep knowledge and expertise in container orchestration to manage AKS.
AKS is certainly an ideal platform for developers to develop their modern applications using Kubernetes on the Azure architecture where Azure Container Instances are the pretty right choice to deploy containers on the public cloud. The Azure Container Instances help in reducing the stress on developers to deploy and run their applications on Kubernetes architecture.
→ Elastic Provisioning of capacity without the need to manage the infrastructure and with the ability to add event-driven autoscaling and triggers through KEDA
→ Most comprehensive authentication and authorization capabilities using
→ Available in more regions than any other cloud provider.
→ AKS streamlines horizontal scaling, self-healing, load balancing, secret management.
Common uses for Azure Kubernetes Service (AKS):
→ Easily migrate existing application to container(s) and run within the Azure managed Kubernetes service (AKS).
→ Use AKS to simplify the deployment and management of microservices based architecture.
→ Implementing secure DevOps together with Kubernetes on Azure, you can achieve the balance between speed and security and deliver code faster at scale.
→ Training machine learning model is also possible with help of AKS
Industry UseCase: Bosch
Bosch increases vehicle safety using map-matching algorithms and Azure Kubernetes Service. When Robert Bosch set out to solve the problem of drivers going the wrong way on highways, the goal was to save lives. Other services like this existed in Germany, but precision and speed cannot be compromised. So the company developed the wrong-way driver warning (WDW) service and software development kit (SDK) which was designed for use by app developers and original equipment manufacturers (OEMs). This architecture pivots on an innovative map-matching algorithm and the scalability of Microsoft Azure Kubernetes Service (AKS) in tandem with Azure HDInsight tools that integrate with the Apache Kafka streaming platform.
Major use cases included a reference to simple and faster deployment and management of container-based applications. Presently, AKS is gaining recognition gradually and will be the benchmark for exclusive container orchestration platforms in the future.
