An Introduction to RabbitMQ:
Message broker works on the producer, broker, and consumer logic. Message broker server allows consumer and producer server to respond request fast instead of using resources heavily at one time. Message broker is used to optimize the load on the server and provide services until application executes the task on the requested server. The requested server can be any third party application which performs the task.
Queued messages will be used to send the messages or task to multiple recipients from consumption that leads to the load balancing on the producer and consumer server.
Let take an example of ruby on rails server and bitcoin exchange server (i.e. bitcoind) for btc transaction working.
I have rails server running as producer and bitcoind server as a consumer.
Rails server send multiple request to bitcoind server continuously. There may be chances to slow down bitcoind because of multiple requests send to bitcoind server to process task.
In that case, RabbitMQ can fulfill the role of load balancing and messages passing by keeping the request coming from rails server in a queue and serve request one by one to bitcoind server.
Bitcoind server will take a task from the queue and start processing.
AMQP store and forward messages to consumers, same as SMTP protocol which is used to deliver mail to mailboxes. Messages start from producer application to the exchanges that help to redirect in queues. Lastly, queues deliver task to the consumer application. It's now consumer's server responsibility to take the messages from queues to process as required.
A virtual channel is used to establish the connection between publishing messages from the queue. All process exchanges done over the channels.
Using Bunny ruby RabbitMQ client, we can integrate RabbitMq with rails application. There are some gems available to start with RabbitMQ in ruby like
Bunny help rails application to interoperate with the consumer application, it can be built in any technologies irrespective of the size and complexity of the application. Also, add anampq gem in rails Gemfile to use AMQP protocol services.
RabbitMQ installation commands in Ubuntu:
1] Step 1: Update system
2] Step 2: Install Erlang
RabbitMQ is written in Erlang, you need to install Erlang before you can use RabbitMQ:
3] Step 3: Install RabbitMQ
4] Step 4: Start the Server
Thus if you are looking for web development services which is faster, reliable, redundant and scalable then you can definitely opt for Ruby on Rails RabbitMQ. Hire RoR developers for developing a robust messaging software.
