Comparison of WAS and WebSphere MQ messaging

Comparison of WAS and WebSphere MQ messaging

If we are not already an established user of either WebSphere Application Server or WebSphere MQ, and you are considering whether the service integration platform or WebSphere MQ better meets the messaging needs, use this table to compare the main features of the two platforms.

integration and WebSphere MQ main features. The first column of this table lists the main features of service integration (the default messaging provider for WebSphere Application Server), and the second
Service integration (the default messaging provider for WebSphere Application Server) WebSphere MQ
Closely integrated with WebSphere Application Server, and combines well with the Java EE Can connect to almost any platform, and supports a heterogeneous environment
Supports multiple languages through XMS clients, and multiple platforms Supports multiple languages and multiple platforms
Limited tooling support, other than what is provided in WebSphere Application Server Has many Independent Software Vendor (ISV) tools
Provides strong performance for both persistent and non-persistent messages for JMS Supports JMS and non-JMS messaging interfaces, and provides strong performance for non-JMS applications
Designed for a maximum message size of about 40 megabytes on a 32-bit operating system (subject to heap usage) Supports large message sizes up to about 100 megabytes
Underpins WebSphere Enterprise Service Bus and WebSphere Process Server Underpins WebSphere MQ and WebSphere MQ File Transfer Edition
Included in a single administrative model for WebSphere Application Server, WebSphere Enterprise Service Bus, and WebSphere Process Server Can integrate existing infrastructure and applications (for example, CICS )
Clustering is integrated with WebSphere Application Server clustering for high availability and scalability WebSphere MQ clustering provides selective parallelism of clustered queues

If the existing or planned messaging environment involves both WebSphere MQ and WebSphere Application Server systems, the messaging platform that you choose for a given task does not necessarily determine which JMS messaging provider you should use. For more information, see Choose messaging providers for a mixed environment.
