The invention relates to the field of development of computer 
application software, in particular to an integrated high-performance 
application software architecture and a construction method thereof. The integrated high-performance 
application software architecture comprises a WEB layer cluster, a backend application cluster, a 
database cluster and a message-oriented 
middleware cluster, wherein the WEB layer cluster supports a J2EE cluster technology and is used for providing the capacity of a business 
presentation layer of a J2EE frame; the backend application cluster supports the J2EE cluster technology and is used for providing the 
processing capacity of a 
business logic layer of the J2EE frame; the 
database cluster supports the J2EE cluster technology and is used for providing the capacity of a 
data access layer of the J2EE frame; and the message-oriented 
middleware cluster supports the J2EE cluster technology and is used for providing the message communication capacity between distributed J2EE components. Based on the integrated high-performance application 
software architecture and the construction method thereof, a 
software architect and a developer can determine a 
software scheme and a deployment scheme within short time and provides high-performance application service; and a J2EE application 
system designed according to the 
software architecture can meet the requirements on 
high availability, 
extensibility and 
fault tolerance.
