Kubernetes architecture has a master node and worker nodes. Kubernetes is an open-source Container Management tool which automates container deployment, container (de)scaling & container load balancing. It is here where pods are scheduled. Kubernetes then implements the desired state on all the relevant applications within the cluster. Kubernetes as an orchestration tool allowing you to run and manage your container-based workloads. If left unattended, this property would make pods highly unreliable. Kubernetes architecture: Master and API server. Kubernetes operates using a very simple model. The Key-Value Store, also called etcd, is a database Kubernetes uses to back-up all cluster data. A 3rd party software or plugin, such as Docker, usually performs this function. Google has initially developed Kubernetes on the Go programming language. The ReplicaSet configuration defines a number of identical pods required, and if a pod is evicted or fails, creates more pods to compensate for the loss. So a cluster is a set of nodes grouped together. Virtualized deployments allow you to scale quickly and spread the resources of a single physical server, update at will, and keep hardware costs in check. It can lead to processing issues, and IP churn as the IPs no longer match. Like containers, it is designed to run anywhere, including on-prem, private, public cloud, and even in the hybrid cloud. Kubernetes is very powerful, but at the same time also complex. This new pod is a replica, except for the DNS and IP address. ≈ Leave a comment. Kubernetes Architecture Explained in Brief Kubernetes has become the most sought after orchestration platform because of its overwhelming features, including scaling, auto-deployment, and resource management across multiple clusters of hosts. Kubernetes has two nodes—Master Node and Server Node. If you need to scale your app, you can only do so by adding or removing pods. Modern applications are dispersed across clouds, virtual machines, and servers. Watch now! K8s transforms virtual and physical machines into a unified API surface.
