Hi There!
Answers inlined:
Compared to commercial messaging products like MQ series/Tibco EMS etc how does ActiveMQ performs interms of:
1)Handling large number of small messages(generally used in Telecom apps)?
ActiveMQ performs well - and is currently being used by a number of telecom providers. Its also been used for real-time data feeds and is being used by CERN's LHC projects.
2)Handling large number of messages of big size.(generally used in finance apps)
Depends on how large you mean ? For messages up to 10mb - you don't need to do anything other than use the default message settings. You need to ensure you have ample memory allocated in the ActiveMQ broker configuration. For larger messages, you can either use BlobMessage (out of bound messaging) - or JMS Streams - which comes with ActiveMQ
Many commercial products have facility of load balancing/fault tolarance for their messaging products.In case of Active MQ, how easy it is do these?
The ActiveMQ client offers seamless failover, taking care to ensure messages are not lost or duplicated. load balancing is also catered for, as is clustering and store and forward. All these topics, including performance tuning are covered in the book!
