As we know the benefits and usage of docker, this article presents you its applications.
Simplifying Configuration
Docker can do the same thing as a virtual machine but without the overhead. It allows you to configure and deploy your environment and settings. The same Docker configuration can be used in a number of different scenarios. This separates the application environment from the infrastructure requirements.
Developer Productivity
Docker delivers for a dev productivity use case. A development environment typically has limited memory capacity, yet Docker easily allows a few dozen services to function by not adding to the memory footprint that is common when using a VM.
Server Consolidation
Docker’s application isolation capabilities make it possible to consolidate numerous servers and save money. Docker, on the other hand, allows significantly denser server consolidation than VMs since it lacks the memory footprint of multiple OSes and the capacity to distribute unused memory among instances.
Debugging Capabilities
Docker offers a variety of tools that aren’t particularly container-specific, but they do integrate nicely with the concept of containers. They also come with a lot of beneficial features. This contains the ability to checkpoint and diff two containers, as well as checkpoint and version containers. This can be really helpful when it comes to repairing an application.
Multi-tenancy
It was simple and inexpensive to use Docker to establish separate environments for each tenant to run several instances of app tiers. Given the speed with which Docker environments spin up and the ease with which we can programmatically spin containers, this was doable.
