Originally developed by Google as an offshoot of its Borg project, Kubernetes has established itself as the de facto standard for container orchestration. Additionally, most container orchestration tools are built with Docker containers in mind. And containers are supported in just about any kind of environment these days, from traditional on-premise servers to public cloud instances running in Amazon Web Services (AWS), Google Cloud Platform (GCP), or Microsoft Azure. The beauty of container orchestration tools is that you can use them in any environment in which you can run containers. Once the container is running on the host, the orchestration tool manages its lifecycle according to the specifications you laid out in the containerвЂ™s definition file (for example, its Dockerfile). You can even place containers according to labels or metadata, or according to their proximity in relation to other hosts-all kinds of constraints can be used. When itвЂ™s time to deploy a new container into a cluster, the container orchestration tool schedules the deployment and looks for the most appropriate host to place the container based on predefined constraints (for example, CPU or memory availability). Typically, teams will branch and version control these configuration files so they can deploy the same applications across different development and testing environments before deploying them to production clusters.Д¬ontainers are deployed onto hosts, usually in replicated groups.

These configurations files (for example, docker-compose.yml) are where you tell the orchestration tool where to gather container images (for example, from Docker Hub), how to establish networking between containers, how to mount storage volumes, and where to store logs for that container. When you use a container orchestration tool, like Kubernetes or Docker Swarm (more on these shortly), you typically describe the configuration of your application in a YAML or JSON file, depending on the orchestration tool. Configuration of an application in relation to the containers running it.

Health monitoring of containers and hosts.

Load balancing of service discovery between containers.

External exposure of services running in a container with the outside world.

Allocation of resources between containers.

Movement of containers from one host to another if there is a shortage of resources in a host, or if a host dies.

Scaling up or removing containers to spread application load evenly across host infrastructure.

Redundancy and availability of containers.

Provisioning and deployment of containers.

Software teams use container orchestration to control and automate many tasks: So, what is container orchestration?Д¬ontainer orchestration is all about managing the lifecycles of containers, especially in large, dynamic environments.

When youвЂ™re operating at scale, container orchestration-automating the deployment, management, scaling, networking, and availability of your containers-becomes essential. If, on the other hand, you have 1,000 containers and 400 services, management gets much more complicated. If you have ten containers and four applications, itвЂ™s not that difficult to manage the deployment and maintenance of your containers. The benefit, especially for organizations that adhere to continuous integration and continuous delivery (CI/CD) practices, is that containers are scalable and ephemeral-instances of applications or services, hosted in containers, come and go as demanded by need.Д«ut scalability is an operational challenge. In microservice architectures, applications are further broken up into in various discrete services that are each packaged in a separate container. In just a few short years, containers have dramatically changed the way software organizations build, ship, and maintain applications.Д¬ontainer platforms, led by the seemingly ubiquitous Docker, are now being used to package applications so that they can access a specific set of resources on a physical or virtual hostвЂ™s operating system.
