You must read – Docker Advantages and Disadvantages

i. Easily Scalable

Due to lightweight containers of Docker, they are very easily scalable.

ii. Easy and Faster Configuration

The best feature of docker is we can configure the system easily and also faster. In other words, it is possible to deploy our code in less time and effort with the help of Docker. The requirements of the infrastructure are no longer linked with the environment of the application as Docker can be used in a wide variety of environments.

iii. Ability to Reduce the Size

By providing a smaller footprint of the operating system via containers, Docker has the ability to reduce the size of the development.

iv. Increase Productivity

Using Docker equals to increase in productivity. Simply put, its increase productivity, by easing technical configuration and rapid deployment of the application. Moreover, it helps to execute the application inane isolated environment and also reduces the resources.

v. Reduced Infrastructure and Maintenance Costs

While accelerating our time to market for new solutions, Docker delivers immediate value to our business by reducing the infrastructure and maintenance costs of supporting our existing application portfolio.

vi. Application Isolation

Docker offers containers which are further used to run applications in the isolation environment. The best thing about this Docker feature is here each container is independent to another and further, it permits us to execute any kind of application required.

vii. Swarm

Basically, Swarm is a scheduling and clustering tool for Docker containers. It uses the Docker API as its front end, that allows us to use various tools in order to control it. In addition, it helps us to control a cluster of Docker hosts as a single virtual host. It’s a self-organizing group of engines that are used to enable pluggable backends.

viii. Routing Mesh

Docker offers Routing Mesh feature, it helps to route the incoming requests for published ports on available nodes to an active container. Even if there is no task is running on the node, it enables the connection.

ix. Services

The list of tasks that lets us specify the state of the container inside a cluster, services. Basically, each task represents one instance of a container which should be running and Swarm schedules them over nodes.

x. Security Management

In order to save secrets into the swarm itself and further choose to give services access to certain secrets, Security Management permits us. Basically, it gives some important commands to the engine like a secret inspect, secret create and many more.

So, this was all in best Docker Features. Hope you like our explanation.
