The SunGard Financial Systems Macro Architecture


The SunGard Macro Architecture is SunGard Financial Systems' prescribed platform for solution design, development and deployment. It defines an agile, stable and scalable platform based on a limited set of technologies and a common approach to using these technologies, which will help SunGard to provide solutions for customer business activities using components and systems from SunGard, third-party vendors and customers themselves, with minimum cost, risk and time to market.

Furthermore, the Macro Architecture will help to


The Macro Architecture defines the following key elements:

Architecture Layers


The Integration Layer

The Integration Layer is used to expose business functions of systems in arbitrary technologies as endpoints for standardized communication protocols.

Events on these endpoints (e.g. incoming messages or files) can be processed (e.g. by filtering or transformation) and routed to other endpoints consuming the result of the processing.
In the Macro Architecture, the use of processing and routing is limited to low-level operations, as any business-relevant operation has to be performed by the Process Layer. Hence, the Process Layer and the Integration Layer together are providing the functionality of an Enterprise Service Bus.


The default technology option for the Integration Layer is the use of Apache Camel, combined with additional functionality for the proper integration of Camel with the Macro Architecture. This combination is referred to as the Infinity Service Bus (ISB), and is maintained by Stardust. Stardust also provides technical enabling support for the ISB within SunGard.

Camel provides rule-based message routing, message persistence, and well-defined interfaces. Through URIs, it supports numerous transport and messaging models, including HTTP, ActiveMQ, JMS and JBI. It supports a large number of message data formats, using plug-in formatting components.

It should be emphasized that ISB is not intended to provide an Enterprise Service Bus product out-of-the-box but successively and on Segment request provide functionality needed for the Integration Layer.
For scenarios where throughput or latency of the ISB is considered insufficient, low latency technologies (e.g. IBM Websphere MQ Low Latency Messaging) and possibly even hardware appliances may be considered.
If used for event processing, Complex Event Processing (CEP) technologies (e.g. Streambase) may be considered, whenever multiple events in a time window have to be correlated.

Example Uses

A frequently encountered use case is to decouple previously tightly-coupled legacy components and systems participating in an overall business process, allowing them to be replaced individually and transparently to the rest of the process. This lets customers to upgrade and improve infrastructure and processes as necessary, enabling them to avoid a costly and risky "rip and replace" approach.
Use of ISB is also essential to moderate or eliminate complex point-to-point communications in large composite solutions. ISB can also be used for event processing scenarios, to detect and filter business events on endpoints and initiate further processing.

Integration Strategy

With the layers and the componentary of the Macro Architecture, new functionality can be provided on top of existing systems by
