I'm trying to create a C# program using ActiveMQ.
The main goal here is to experiment how to use ActiveMQ to send push messages to a client from a server which is supposed to be the message broker using the pub/sub pattern. The clients are web clients which are implemented with React.
There's an official link which suppose to have .NET examples of using ActiveMQ:
https://activemq.apache.org/components/nms/documentation#providers
What is the difference between the providers listed? What provider do I need to use in order to achieve my goal listed above? Is using this method means using ActiveMQ Artemis?
The Openwire based NMS client (NMS.ActiveMQ) speaks a protocol that supports most JMS style behaviours and is interoperable on both ActiveMQ 5.x and the more actively developed ActiveMQ Artemis.

I am new to Nservicebus and have recently started working in it. I am stuck on a point and need input from you guys. I have 2 asp.net core web api projects and I want to use NServicebus to send messages between both of them in some scenarios.
What I have found so far that I can provide name to EndpointConfiguration, what if one of my api is deployed on 1 server and 2nd on another server, in that case how my configuration should be?
I tried to gave url instead of name in EndpointConfiguration but it gave me exception.
Thanks in advance for your help
NServiceBus endpoints communicate over some messaging infrastructure your system will be using. Endpoint names represent queues messages sent to. Messaging infrastructure is abstracted by what NServiceBus is calling a Transport. You will need to decide on the transport you'd like to use (see the options here). Once you've decided what transport your solution will use, you could have a look at the samples for that specific transports to have an idea how to set up your endpoints.
For example, if you'll decide to use Azure Service Bus as your transport, you could download and try the Send/Reply sample.
A good starting point could be the tutorials available on the documentation site here.
Axon Framework supports Distributing Events which should allow to post events to the external message broken and read events from message broker.
Amazon provides two different messaging services
Amazon Simple Queue Service (SQS)
Amazon MQ
Questions:
What Amazon messaging service might be used (SQS, MQ or may be both) as message queue with Axon Framework?
What is the best practice for implementing distributed Axon message processing in Amazon EC2 cloud?
It looks like that Amazon MQ should work fine with Axon Framework as message queue because it supports AMQP. But I failed to find any references about any practical experience using MQ with Axon.
Any messaging service implementation which supports, AMQP should work just fine with the Axon Framework. More specifically together with the axon-amqp dependency, as you might already have found out.
Without personally having any experience with Amazon SQS or MQ, I did a quick search on both, and it seems Amazon MQ is indeed the go to solution to distributed your events on Amazon EC2.
I do not have or heard any best practices for distributed your Axon Framework events over Amazon EC2 specifically, sadly enough, but I can share this.
All the Axon Framework (when adding the axon-amqp dependency) does, is subscribe to the EventBus and publish any incoming events on a queue; no further specifics.
Hence I'd say any best practices for general use of Amazon MQ should apply on your second question.
Hi went through Enterprise Integration Patterns by Gregor Hohpe and Bobby Woolf.
http://www.eaipatterns.com/toc.html
I also went through Camel and Mule's compliance with these integration patterns -
http://www.mulesoft.org/documentation/display/current/Understanding+Enterprise+Integration+Patterns+Using+Mule
http://camel.apache.org/enterprise-integration-patterns.html
I see that both Mule and Camel allow applications to be deployed and accessed via webservices like SOAP or REST, SOAP being more RPC style. They allow massive integration support using opensource utilities like CXF and Jersey. In fact Mule also supports RMI endpoints - which will give remote method invokation capability as well which is a well-accepted form of Integration.
I understands ESBs are built around a Message Bus with additional support for other protocols however ESBs only comply to EIP and EIP is not just ESBs.
Question is why SOAP/REST or their transport protocol not considered as "Integration Styles" and which is Enterprise Integration so "Message Oriented"?
I am a novice compared to the great minds which designed these patterns but trying to understand the lopsided message-y nature of Integration patterns. I admit it isn't quite the QnA format of stack overflow but will request Mods to keep it alive for a while so that people can share their opinions.
As for SOAP, it would put it under the Integration Style "Remote Procedure Invocation", since it's pretty much what SOAP implements in reality (I won't consider the SOAP over JMS hybrids here with a potential to mix RPC with Messaging..).
REST is, interface wise, very different from SOAP in that it's resource driven instead of service driven. I would non the less group it under the "RPC" style since it's just another format of syncrhonous RPC calls.
I would, however, not put too much effort in theory of what EIP integration style a specific message pattern implements.
Look at a specific scenario at hands instead and use the EIP to model your specific integration.
I've seen integrations of file transfers that in realtiy implemented RPC patterns or SOAP services that in reality implemented messaging (although I don't really recommend do this).
A concrete example: consider the usage of a dedicated file upload service, which happends to be built using SOAP technolgy, which uploads a CSV file to a file area on a server, from where it's picked up by some other system. I would call this file based integration on a high level.
Another example is that Messaging systems sometimes are implemented using a shared database. Still the integration style using them is messaging, not "Shared Database".
Think about how your integration should work on a high level, then apply the various protocols to do the grunt work.
Is it possible to scale out SignalR using Windows Server Service Bus?
I found sample of doing it with Redis, and I know there are libraries in GitHub for SQL Server (although I couldn't find a working sample for that), but I would like to implement it using the new on-premises Service Bus.
Any ideas / references?
Thanks!
In theory yes. The current stable versions support the Azure Service Bus, the latest source includes a rework of the scaleout providers such that even if it doesn't work out of the box (as the two service bus solutions are designed to have API parity) it should be straightforward to implement.
The service bus scaleout is enabled using its DependencyResolverExtensions class.
NServiceBus and MassTransit are two tools that can be used to implement messaging with MSMQ and other message queues.
I find that once you start using messaging to have applications talk to each other, you don't really want to go back to the old RPC style.
My question is, what other tools are out there? What tools do you use?
Apache ActiveMQ is probably the most popular and powerful open source message broker out there with the most active open source community behind it as well as commercial support, training and tooling if you need it.
One of the more interesting aspects of ActiveMQ is its wide support for a large number of different language bindings and transport protocols
WebSphere Message Broker is IBM's flagship ESB which runs ontop of MQ.
They also produce WebSphere ESB which is a slightly lighter offering which specialises in ESB across web services.
We use WCF services for synchronous message based operations, and nServiceBus for anything asynchronous.
Rogue Wave is very popular [ http://roguewave.com/products/hydra/ ]
So are IBM's Websphere offerings [ http://en.wikipedia.org/wiki/Mqseries ]
WCF is extremely powerful and should be looked into by anyone in the .NET space starting up a message based system.
I would recommend against BizTalk unless you can make a lot of use out of it's adapters (ie. you have a lot of old systems to communicate with).
Nuedesic makes a great WCF based ESB, Neuron, if you are willing to pay a bit.
I use IBM software stack because it has the widest set of features (pub/sub, async, sync) and platform support (60+ combination of platform, languages) and also a great set of free tools provided by IBM
For Operations, I use use the linear log rotation IBM WebSphere MQ supportpac
For development and testing, I like RFHUTIL to generate fake cobol, java, MS objects, other binary and text objects and SOAPUI to invoke HTTP web services. If I need to invoke MQ based web services, I go back to RFHUtil. Of course Websphere MQ Explorer for admin.
We use the old WebSphere Message Broker 6.1 (now IBM Integration Bus) that is fast and reliable once you are acquainted.
