Should I learn docker or javaee?

With the advent of the cloud computing era, containerization has become a new technology trend. In this trend, Docker, as a containerization technology, has become one of the most popular choices. As a mature enterprise-level application development framework, JavaEE also occupies an important position in the market. So when studying, should we choose to learn Docker or JavaEE?

1. Docker

The emergence of Docker has made "environment configuration, development environment, deployment environment and other issues" a thing of the past. Even developers with different operating systems can easily share them. A copy of code also provides the ability for rapid deployment and horizontal expansion. Docker is not only widely used in the field of DevOps, but also has a wide range of application scenarios in cloud computing, microservices and other fields. It can be said that Docker plays a very important role in modern application development.

In addition, Docker also has the following advantages:

1. Provides comprehensive component support and can start, package and deliver application components at any time;

2. Supports rapid creation and destroy containers, making it easier to deploy and upgrade;

3. Improves efficiency and reduces development iteration time, thereby improving user satisfaction;

4. Supports multiple application development Languages ​​and technologies, as long as your application adheres to container standards.

2. JavaEE

Java Enterprise Edition (JavaEE) is an extension of Java that provides a set of specifications for writing Java-based enterprise applications. JavaEE has unique advantages, such as:

1. Portability: Java’s portability allows it to run in various environments and can be easily migrated to servers for deployment. It can also be deployed on In a cloud environment;

2. Security: Java is a compiled language that can detect many security vulnerabilities in the code and also provides security management;

3. Scalability : Java EE has multiple extension points, which can be used in various enterprise-level applications and can be extended to any useful function;

4. Maintainability: Java EE supports easier application maintenance .

JavaEE also has some shortcomings:

1. Explicit deployment: The deployment of JavaEE applications is relatively complicated and needs to be deployed on a JavaEE server, which requires some professional knowledge;

2. Interoperability: Interoperability between JavaEE and other non-Java technologies is relatively complex and requires some special tools and technologies.

3. Conclusion

Although Docker and JavaEE have their advantages and disadvantages, both have their important positions in modern application development. From a beginner's perspective, Docker may be more suitable for beginners to get started because it is easier to understand and believe in. Learning Docker can not only help you quickly package and build applications, but also help you understand the advantages of Docker and container technology. Through Docker learning, you can learn about best practices in DevOps, cloud computing, microservices, container orchestration and other fields.

And if you are already familiar with Docker and want to delve deeper into Java application development, then learning JavaEE may be more suitable for you. JavaEE provides some enterprise-level specifications and tools to support the development and deployment of Java applications.

To sum up, whether to learn Docker or JavaEE completely depends on your goals and experience. If you are a beginner, it is recommended to learn Docker. If you already have some experience or want to further study Java application development, learning JavaEE is a good choice. No matter which technique you choose, learning and practice are key.
