Application containerization allows you to independently operate containers in distributed applications and microservices. The modular characteristic of containers helps you to reduce interdependency and process failures. Each part of the application communicates with the other using designated APIs.
Docker technology is gradually replacing the use of virtual machines. The necessity to lodge a whole operating system makes virtual machines a lot heavier than containers. Containers use the host operating system to boot and run, reducing machine strain while increasing performance and speed. Security is generally strengthened in a containerized application since containers are isolated – reducing the probability of chain events.
