With each passing year, Docker's popularity grows. Can you think of any explanation for this? It has altered the process of creating software. Containers from Docker enable massive economies of scale and user-friendliness in the development process while also making it scalable.
What exactly is ‘Docker?’
First, let's have a basic grasp of what Docker is all about. Using Docker, IT departments can simply design, deploy, and execute programmes in isolated containers that contain all of their dependencies. All the instructions and dependencies, such as frameworks, libraries, or binaries, are contained within the container itself.
The container itself is lightweight and portable, making it ideal for moving from one location to another. For DevOps, Docker really shines in deployment because you want to be able to guarantee that the code that has been tested will actually operate in the production environment when you deploy your solution.
Docker is useful throughout the DevOps lifecycle, but deployment is where you'll see the most benefit from it. The advantages of using Docker will be discussed next in this guide.
Advantages of using Docker
In this section of our Docker tutorial, we'll go over some of the software's benefits.
- Scalability
If your applications demand additional containers, you may easily build new ones in a matter of minutes. There are a variety of container management options available when running multiple containers. More information about these settings can be found in the Docker documentation.
- Agility
Containers' flexibility and responsiveness are enhanced by their portability and performance. The right software may be delivered at the right moment with the help of Enterprise Developer Build Tools for Windows and other containers in your continuous integration and continuous delivery processes.
It's possible to compile, build, and test COBOL code without having to use an IDE with Enterprise Developer Build Tools for Windows, a component of Enterprise Developer.
- Portability
As long as Docker is installed and operating on the target system, your containerized application can be deployed to any other Docker-enabled system.
- Isolation
Docker containers that contain one of your apps also include the relevant versions of any supporting software that the application requires. No problem if other Docker containers have apps that require different versions of a certain supporting package because the containers are completely independent of one another.
In other words, no matter where you are in the development process, you can rest assured that any image you create will function flawlessly as it progresses through testing and, eventually, to your users.
Now that you've learned about the benefits of Docker, it's time to come towards the end of this guide now.
Conclusion
We now have a better understanding of why Docker containers and micro services are becoming so popular. Docker simplifies infrastructure management by reducing the weight, speed, and robustness of the underlying instances. Because Docker isolates the application layer from the infrastructure layer, it provides the software delivery chain with much-needed portability, cooperation, and control. Understanding Docker's architecture will help you get the most out of your containerized apps, which is suited for modern DevOps teams.
