No more filling out forms to request new machines to run your application! Just provision and go, and take advantage of the tooling developed around Kubernetes for automating packaging, deployment, and testing. If they need more resources to handle additional load, they can get those just as quickly, since resources all come from an infrastructure shared across all your teams. Your development teams can quickly and efficiently request the resources they need. Indeed, Kubernetes allows you to deliver a self-service platform-as-a-service (PaaS) that creates a hardware abstraction layer for development teams. Practitioners are moving to Kubernetes for four main reasons:ġ. OK, but why all the buzz? Why is Kubernetes so popular?Īs more and more organizations move to microservice and cloud native architectures that make use of containers, they’re looking for strong, proven platforms. Easily performing canary deployments and rollbacks.Automatically leveraging additional resources made available when a new host is added to the cluster.Moving an application instance from one host to another if there is a shortage of resources in a host, or if the host dies.Monitoring resource consumption and resource limits to automatically stop applications from consuming too many resources and restarting the applications again.Automatically load balancing requests across the different instances of an application.Evenly spreading application load across a host infrastructure.Controlling resource consumption by application or team.

It does so by creating an abstraction layer on top of a group of hosts, so that development teams can deploy their applications and let Kubernetes manage the following activities: Kubernetes makes it easy to deploy and operate applications in a microservice architecture. In fact, Kubernetes has established itself as the defacto standard for container orchestration and is the flagship project of the Cloud Native Computing Foundation (CNCF), backed by key players like Google, AWS, Microsoft, IBM, Intel, Cisco, and Red Hat.

Originally developed by Google, Kubernetes is an open-source c ontainer orchestration platform designed to automate the deployment, scaling, and management of containerized applications.
#What is kubernetes in simple terms software
Large and small software companies alike are now deploying thousands of container instances daily, and that’s a complexity of scale they have to manage. Containers help companies modernize by making it easier to scale and deploy applications, but containers have also introduced new challenges and more complexity by creating an entirely new infrastructure ecosystem. Container-based microservices architectures have profoundly changed the way development and operations teams test and deploy modern software.
