MassTransit production usage stories/experiences

[Jeremias Kauppinen]

Hello guys,

Firstly I just want to say that I have been researching MassTransit for a while now and I really like it. Our company is in process of possibly establishing our messaging architecture on top of MassTransit and RabbitMQ. Any of you guys willing to share your current architecture and experiences regarding MassTransit with RabbitMQ?
It would give comfort to some C-level executives to give a couple of successful stories about this product.

Thanks in advance

Jeremias,

I can say that there are banks currently using MassTransit to process millions of dollars of transactions daily. Novell is using it to manage one of their cloud offerings (check list history for more details). There's an order processing system using it, but I don't hardly of the details. Multiple products at McKesson, a healthcare company, uses this stack processing 100s of millions messages a day. Microsoft uses MassTranist (on MSMQ) for something internally, but they never told me what. 

Specific architectures might differ but generally import key points:

- cluster RMQ

- load balancer in front of the cluster

- at high volume, RMQ will be io bound on windows

- running out of disk space on a RMQ node has nasty behaviour (blocks all threads)

- don't cluster over WAN, erlang doesn't handle latency well; other tools to use in that case

- break up workflow into small units

Cheers,

I've used MT for about 5 years now, introducing it at Novell in PlateSpin Protect product - isolated set of services running over fast LAN and MSMQ (lesson: networked MSMQ breaks for no apprent reason now and then).

Used it as a foundation tech later on in building a SaaS offering for FuturestateIT - AWS + RabbitMQ cluster (RabbitMQ cluster handles AWS network issues better than rabbitmq client library).

About to go live at S&P with a first deployment of services talking over MT, lesson here - infrastructure setup takes extraordinary amount of time in a big corp, find a way to automate.
