RabbitMQ is one of the many caching and messaging tools that uses local disk persistent storage or as a backing store for in memory data.  These systems normally put data to disk in some format that is optimized for speed and not for security. Ex: RabbitMQ, ActiveMQ, Coherence, Gemfire, MongoDB. This can cause issues when trying to comply with policies around protecting Personally Identifiable Information  , making systems Payment Card Industry Data Security Standard (PCI DSS) compliant or when implementing S/Ox controls. RabbitMQ Installation We assume that you are running RabbitMQ under the local system account.  Users who run RabbitMQ under different accounts or in different locations must change certain commands or settings.  The RabbitMQ team has a good set of documentation on their web site.

NServiceBus acts as a .Net (C#) distributed messaging abstraction layer for message-driven systems.  It runs on top of a variety of transports including MSMQ, Azure Storage Queues, ActiveMQ on RabbitMQ.  This blog describes how NServiceBus configures and uses RabbitMQ using the Video Store Sample program available in the NServiceBus github repository   . It looks like the images attached to this article have been removed from the google image store Background Message-driven systems are asynchronous distributed systems that have two main message concepts, at least in our project. They have commands, targeted messages, where the sender knows the intended destination. The producer sends the messages to a target. They also have publish/subscribe or event-based messages where the sender target is unknown. The sender posts the event which is then received by parties that have registered interest, and subscribed. Producers: Programs that send messages or post events...

Cloud Foundry - PaaS Each Cloud Foundry instance is a self contained environment (cloud) that is generally intended to be use as a black box application container. It is implemented in a virtualized environment that hides the actual virtual/physical topology from the deployer.  Service configuration, provisioning, log viewing and application deployment are done from outside the cloud through external tools.  Cloud services may use any ports or other resources and use unique usernames and passwords for each instance. Applications rendezvous with services, at run time, via declared service names. Cloud services are not visible outside the container.  All system monitoring must be done through log files, through code deployed in the application or through tooling provided by Cloud Foundry. Service tunneling, where you can bind to the data port of a provisioned service, will be added to Cloud Foundry in a post 1.0 release.  This blog article  describes how it w...

AMQP is an open protocol for Asynchronous message queueing.  The number one implementation for AMQP is RabbitMQ.   I normally run RabbitMQ on my Mac in a Linux/Ubuntu VM  but I recently got a new Macbook Air that's limited to 4GB.  I wanted to run RabbitMQ native on the Macbook Air instead of the Linux virtual machine to save space and give me better performance when running tcServer, RabbitMQ and STS on this slightly smaller machine.  Installation RabbitMQ is written in Erlang.  The Mac doesn't come with Erlang so you have to install it. You can use Macports or Homebrew per the Rabbit installation instructions .  I'm lazy so I used Rudix    Erlang-Solutions   which provides Erlang in neat Mac installation packages that put the files in  /usr/local /usr/bin. (The rudix version of Erlang went away over the weekend of 11/12/2011).  Download the img/package mentioned above and install it like any other .img fi...
