Unveiling RxMule

As Rx is gaining traction, more and more developers are getting accustomed to its concepts and primitives

I'm super excited to announce RxMule, my latest open source project. RxMule provides reactive extensions for Mule ESB, via a set of specific bindings for RxJava.

For several years, I've been mulling over the idea of creating a DSL for configuring Mule. Indeed, there is a treasure trove of pre-existing transports and connectors for Mule, which is very compelling for anyone building connected applications (which, nowadays, is probably everybody). Unfortunately developers can be put off by the XML-based DSL used to configure Mule, and thus may pass the opportunity to leverage all this available goodness.

As Rx is gaining traction, more and more developers are getting accustomed to its concepts and primitives. With this mind, and knowing that Mule is at core an event processing platform, it dawned on me that instead of creating a DSL that would mimic the XML artifacts (which are Mule specific), I'd rather create bindings to allow using Mule's essential moving parts via Rx.

In summary, RxMule adds a number of classes to RxJava that make it possible to observe:

In short, RxMule allows creating Observable<MuleEvent> instances from different sources. A MuleEvent is what Mule creates and processes. It wraps a MuleMessage which contains the actual data and meta-data that's being processed.

You can read more about the structure of a MuleMessage here.

The following demonstrates an asynchronous HTTP-to-Redis bridge, that only accepts one request per remote IP:

So why don't you take RxMule for a spin and see if it helps you achieving your application and API integration needs: with Mule at its core, I bet it will! Bug reports and pull requests are welcome at GitHub.

The standardization of container runtimes and images has sparked the creation of an almost overwhelming number of new open source projects that build on and otherwise work with these specifications. Of course, there's Kubernetes, which orchestrates and manages collections of containers. It was one of the first and best-known examples of projects that make containers truly useful for production use. However, more recently, the container ecosystem has truly exploded. A service mesh like Istio addresses many of the challenges faced by developers and operators as monolithic applications transition towards a distributed microservice architecture. A tracing tool like Jaeger analyzes what's happening as a transaction moves through a distributed system. Monitoring software like Prometheus captures time-series events for real-time alerting and other uses. Grafeas and Kritis provide security polic...
DevOpsSUMMIT at CloudEXPO will expand the DevOps community, enable a wide sharing of knowledge, and educate delegates and technology providers alike. Recent research has shown that DevOps dramatically reduces development time, the amount of enterprise IT professionals put out fires, and support time generally. Time spent on infrastructure development is significantly increased, and DevOps practitioners report more software releases and higher quality. Sponsors of DevOpsSUMMIT at CloudEXPO will benefit from unmatched branding, profile building and lead generation opportunities.
