From Tuxedo to CRES to Light-JRES: The Evolution of Hundsun Financial Middleware Architecture

#

Introduction: A Two-Decade Journey of Chinese Financial Middleware

#

Hundsun Technologies represents one of the most important evolutionary paths in China’s securities IT history.

Its middleware architecture evolved through:

Tuxedo

↓

AS/AR

↓

CRES

↓

JRES

↓

Light-JRES

This journey reflects the transformation of financial systems from:

Centralized Transaction Processing

↓

Three-tier Architecture

↓

Distributed Services

↓

Cloud-native Microservices

1. The Tuxedo Era: Commercial Transaction Middleware

#

Early Securities Architecture

#

In the 1990s:

Client

|

Application Server

|

Database

was the dominant model.

However, securities firms faced:

• Increasing transaction volume
• Growing branch networks
• Higher reliability requirements

The Role of Tuxedo

#

Financial institutions worldwide adopted:

• BEA Tuxedo
• IBM CICS

Tuxedo provided:

• Transaction management
• RPC communication
• Service scheduling
• High availability

Architecture:

2. AS/AR Era: Hundsun Builds Its Own Middleware

#

Around 2001, China’s securities industry entered the centralized trading era.

The requirement became:

Nationwide Branches

|

Central Trading Platform

|

Core Database

Hundsun developed:

• AS (Application Server)
• AR (Application Router)

3. AS/AR Architecture

#

AR: Application Router

#

Responsibilities:

• Client access
• Request routing
• Load balancing

Benefits:

• Network isolation
• Centralized management
• Enterprise scalability

5. CRES Era: Building a Securities Core Middleware Platform

#

As trading systems became larger:

AS/AR faced new challenges:

• Scalability
• Service management
• High concurrency

Hundsun introduced:

CRES (Core Resource Enterprise System)

6. CRES Architecture

#

CRES became the foundation middleware platform for Hundsun securities systems.

8. CRES and O32 Era

#

Hundsun’s famous investment management platform:

O32

*

CRES

became a mainstream architecture for fund investment systems.

9. JRES Era: Moving Toward Java Distributed Architecture

#

During the 2010s:

Financial IT adopted Internet architecture concepts.

Evolution:

Monolithic Systems

↓

Service-oriented Architecture

↓

Microservices

Hundsun moved from:

C++ middleware

towards:

Java-based distributed platforms.

11. O45 / UF3 and Light-JRES

#

New generation products:

O45

UF3

TA6

are built on:

Light-JRES technology.

Providing:

• Investment management
• Trading execution
• Account services
• Data services

12. Evolution Summary

#

Conclusion

#

Hundsun’s middleware evolution is a reflection of China’s financial IT modernization.

The journey moved from:

Commercial Middleware

to:

Independent Transaction Middleware

and finally:

Cloud-native Financial Platform
