Application Running Method, Node, and Compute Device Cluster

A node comprising:

• at least one compute device configured to:
• store a first JAVA archive of an application;
• and
• run a first container group comprising:
• a first container configured to:
• load a second bytecode of a to-be-enhanced class from the first JAVA archive to obtain a second JAVA archive of the application, wherein the second JAVA archive comprises a first bytecode of the to-be-enhanced class;
• and
• run a first enhancement component that modifies the second bytecode to obtain the first bytecode during loading of the second bytecode;
• and
• a second container configured to:
• load the first bytecode to obtain a first loading result;
• create a first object of the to-be-enhanced class based on the first bytecode during loading of the first bytecode, wherein the first loading result comprises the first object;
• and
• run the application based on the first loading result.

A compute device cluster comprising:

• at least one compute device configured to:
• load, using a first container in a first container group, a second bytecode of a to-be-enhanced class from a first JAVA archive to obtain a second JAVA archive of an application, wherein the second JAVA archive comprises a first bytecode of the to-be-enhanced class in the application, wherein the first container runs a first enhancement component, and wherein the first enhancement component modifies the second bytecode to obtain the first bytecode during loading of the second bytecode;
• load, using a second container in the first container group, the first bytecode to obtain a first loading result, wherein the first loading result comprises a first object of the to-be-enhanced class, and wherein the second container creates the first object based on the first bytecode during loading of the first bytecode;
• and
• run, using the second container, the application based on the first loading result.
