A container is a unit of software that virtualizes the operating system of the host. It gives a virtualized operating system environment that can be saved as an image, transferred over the network, cloned into multiple copies, and recreate the exact same environment as the initial container.
The containers are a useful way to run a unit of software without worrying about the hosting environment. It is useful while replicating the same unit of software. It also is a safer way of running applications since the application runs in the isolation of the container.
Technology like Kubernetes has accelerated the use of containers since it helps in orchestrating the containers, ensuring their health, scaling them up and down, etc.
