To support scaling and help maintain productivity, orchestration tools automate many of these tasks. The orchestration tool will also use system parameters like CPU and memory capacity, and file parameters like proximity and file metadata, to help inform its decisions. The orchestration tool then manages the container's lifecycle based on specifications in the configuration file. When deploying a new container, the orchestration tool automatically schedules the deployment to a cluster and finds the right host, taking into account any defined requirements or restrictions. How does container orchestration work?Ĭontainer orchestration uses configuration files, usually in YAML or JSON format, for each container to instruct the orchestration tool on finding resources, establishing a network, and storing logs. Applications built with microservices as their building blocks are better able to scale, and are more adaptable and easier to manage. Microservices are small pieces of software with simple functionalities for directing narrowly defined tasks, such as opening or updating a file. They further solve this problem through the microservices approach to application development. This is a limitation for developer and IT operations teams alike.Ĭontainers remove these dependencies so developers can build applications that function reliably when IT operations teams move them from one computing environment to another.

What problems do containers solve?Īn application is usually built to function in a single kind of computing environment, which makes it difficult to move or deploy it to another environment. It may use resources from a host, but it usually operates independent of the host operating system and can be used on any platform.Īn application container is not the same as an operating system container, which is a virtual environment that shares the host OS kernel but provides user space isolation and can deliver higher server density, better application performance, and faster server provisioning compared with a hypervisor-based virtual machine. A container, often called an application container, is a portable unit of software that typically provides a microservice and operates in an environment with other containers.
