I normally works in asp.net. But recently I was testing Google App Engine and I found TaskQueues: it's very interesting and powerful. Does anyone know a similar service for asp.net?
I know MSQueue but it's not what I need. I need something like GAE TaskQueue: I put an URL in queue and the URL is triggered (based on queue config).
TyphoonAE is using RabbitMQ to simulate the taskqueue, RabbitMQ provides a .Net client.

You could try Quartz.NET maybe - http://quartznet.sourceforge.net/
Apache ActiveMQ from version 5.4 has a persistent scheduler built into the message broker.
http://activemq.apache.org/delay-and-schedule-message-delivery.html
ActiveMQ supports a variety of Cross Language Clients and Protocols from Java, C, C++, C#, Ruby, Perl, Python, PHP.
You can set a message to wait with an initial delay, and then repeat delivery 10 times, waiting 10 seconds between each re-delivery
You can also use CRON to schedule a message

I have to connect an old but critical software to RabbitMQ. The software doesn't support AMQP, but it can do HTTP Requests.
Does RabbitMQ support plain HTTP? Or should I use a "proxy" or "app" that actively transforms the HTTP Requests to AMQP 1.0 and pushes it to the RabbitMQ server?
https://www.rabbitmq.com/management.html
The management plugin supports a simple HTTP API to send and receive messages. This is primarily intended for diagnostic purposes but can be used for low volume messaging without reliable delivery.
As mentioned, it's designed for very low loads, but it may be usable. If you need higher loads, then by all means cast around for a library that does the job and create a proxy. Most languages will have something. I've personally created a lightweight API using Lumen and https://github.com/bschmitt/laravel-amqp to tie a few disparate services together in the past, and it seems to work very well.
It is possible not but really recommended depending on load. You have three options really, two of which are web socket based and one that seems like what you're looking for. I'd suggest starting with the rabbitmq docs.
We need to load test aspnetcore signalR application. I saw about crank but that
seems to help only with aspnet signalR. Can someone help me with this.
Most probably you need a load testing tool which supports WebSocket protocol as this is what SignalR will be doing by default.
It could be also Server Sent Events, Forever Frame or Long Polling so you need to clarify the NFRs and identify which protocols are in scope and what are the requirements which need to be tested.
Depending on your skills you can go for:
Gatling which has support of WebSocket, but you will need to do some programming in Scala
Apache JMeter which supports WebSocket via the plugin, JMeter allows you to create tests using simple GUI. You will be able to also test Long Polling and Server Sent Events using JMeter, check out How to Load Test Async Requests with JMeter for more details.
Does anyone out there have experience using BlueMix push notification invoked from code written & deployed on Z enterprise (Zos)? What were the basic coding & connectivity components you used?
It's easier than you think.
BlueMix Push has a REST API, so you can use any development tool capable of sending an HTTP request. In our case, we do it with a simple Java app that runs perfectly fine on z/OS, so long as you have network connectivity to the outside world. If you're not into Java, it could be done in C/C++ or even with a scripted utility like Curl or WGET.
Most sites will have some sort of HTTP Proxy and firewall, so you'll need to route your HTTP request through these layers, and this is a good reason to write the code in Java, since it's drop-dead simple. Oracle documents it here: http://docs.oracle.com/javase/tutorial/networking/urls/connecting.html, but you can also just search StackOverflow for plenty of examples.
I'm not sure this is even possible. I'm not a z/OS expert by any stretch but I'm guessing you won't find a suitable compiled binary for that architecture.
Greetings. I'm planning on building a Flex based multiplayer game, and I'm researching what will be required for the server end. I have PHP experience, so I started looking at ZendAMF.
Now in this game, I'll need the concept of rooms, and real time updates to clients in those rooms, so it looks like I'll be using remote shared objects (correct, yes?). I'm not seeing where ZendAMF can support this.
So I found this page: http://arunbluebrain.wordpress.com/2009/03/04/flex-frameworks-httpcorlanorg/
It seems to indicate that ZendAMF isn't going to do what I want. WebORB for PHP seems to be the only PHP based solution that does messaging, but on that page it doesn't mention "real-time" next to it like the Java based ones below it do.
What should I be looking at for the server piece with my requirements? Do I need to make the jump to something like BlazeDS and try to pick up a bit of Java knowledge?
Thanks.
I'd highly reccommed flash media server if you have the cash.
I've had good expereince with it in the past
Both ZendAmf and weborb use http long pulling. Think of it as pinging to check for updates. If you really need TRUE realtime push notification then PHP will not be your answer due to it not having threads or long running processes. WebOrb has several servers in other languages along with BlazeDS, RubyAMF, PyAmf, and of course LCDS from adobe that allows for true messaging.
I think you already know the answer, but for other people looking into this as well:
All *AMF solutions use HTTP as transfer protocol and can't have permanent connection. AMF is sent encoded through HTTP and then it's closed.
When you want to use "real" real-time (RTMP,RTMPT), you have choices like:
opensource: Red5 (Java), BlazeDS (Java), FluorineFX (.NET)
commercial: Wowza Media Server (Java), WebORB (.NET and Java)
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.
