Difficulty in selecting domestic CPU servers: How is the compatibility between Tomcat and Java programs under the Haiguang x86 and Feiteng ARM architecture?

The rise of domestic CPUs has brought new challenges to server hardware selection. This article will focus on analyzing the compatibility impact of Haiguang (x86 architecture) and Feiteng (ARM architecture) CPU servers on Tomcat and Java applications under Linux systems.

The project requires the use of Haiguang or Feiteng CPU servers, which makes the compatibility issues between middleware and Java Web applications the focus. The key lies in the difference between the two CPU architectures: Haiguang uses x86 architecture, while Feiteng uses ARM architecture, which directly affects the software operation environment.

For X86-based Haiguang CPUs, due to their compatibility with Intel and AMD CPU architectures, deployment of Linux, Tomcat, and Java applications usually does not encounter significant problems. Most mainstream Linux distributions, Tomcat versions, and JRE/JDKs provide good support for the x86 architecture and can be used directly, with little difference in performance and functionality.

But the situation of Feiteng CPU (ARM architecture) is different. The ARM architecture differs significantly from the x86 architecture, and it is necessary to ensure that all software versions are compatible with the ARM architecture, including the operating system, Tomcat, and JRE/JDK. If the software is not compiled or ported by the ARM architecture, it may not work properly. Even with the same version of software, the performance on the ARM architecture may differ from that of the x86 architecture.

Therefore, when deploying Tomcat and Java applications on Feiteng CPU server, strict testing must be carried out. Developers need to verify the ARM architecture compatibility of all dependencies and perform comprehensive regression testing to ensure that the application is functional and performance meets the requirements. Only by passing the test can the compatibility and performance performance of the application on Feiteng CPU be finally confirmed.
