Editor's note: With Docker, we can deploy Web applications more easily without having to worry about project dependencies, environment variables, and configuration issues, Docker can quickly and efficiently handle all of this. This is also the main purpose of this tutorial. Here's the author: first we'll learn to run a Python Dewar application using the Docker container, and then step through a cooler development process that covers the continuous integration and release of applications. The process completes the application code on the local functional branch. In the Gith ...

When we talk about how to implement cloud computing, there's a lot of computer resources to manage and share, as well as applications that need to be improved, but there are very few topics and solutions on how to optimize cloud computing. However, when companies are going to decide to use cloud computing on a large scale, we are only focused on recommendations, application management, and major changes in planning - all of which will have an impact on the web. This requires a new approach to cloud computing. Today's network planners realize that "corporate networks" are the true combination of "resource networks" and "access networks." The former connection I ...
