[mule-user] Multiply instances of the same Mule Service

[Denis Bessmertnyj]

For load balancing proposes we want to have multiply instances of the same Mule Service.

Is it possible with Mule? How to implement it?

 

 

Thanks,

And also one additional question: if it is possible to have different instances of the same service,

how we may differentiate services intstances, i.e. for example ESB Client wanna talk to intance1 and then to intstance2,

i.e. Imagine that ESB Client will be some sort of load balancer.

Is it possible to choose desirable instance for ESB Client at runtime and make a request to it?

Guys, note that we want to have multiply instances of the same serice within one Mule instance.

Is it possible with Mule?

If you use pooled component in your service, Mule will automatically create a
component pool and will dispatch requests to multiple instances as needed.
The pooling policy is configurable. You don't have control over the
individual component objects.

Alternatively, you can declare multiple services (probably with singleton or
spring-objct components) and front them with a pass-through component with
custom outbound router, which would give you explicit control over the
dispatch.

Hi,

 

You can configure the same service twice in Mule provided that the name is different. If both instances listen on the same asynchronous endpoint, (theoretically) whichever one is free to process a message will be the one to read the next message off the queue.

 

However, Mule does not have any load balancing features so any other logic that you need will have to be coded.
