The future is Micro Service Architectures on Apache Karaf

There are many descriptions of what constitutes a micro service, and many specifications that could be described as following the pattern. In short, I tend to describe them as being the smallest unit of work that an application can do as a service for others. Bringing together these services we’re able to build larger architectures that are modular, light weight, and resilient to change.
From the point of view of modern systems architecture the ability to provision small applications with full life cycle control is our idea platform. Operators need only deploy the services they need, updating them in place, spinning up additional instances as required. Another way of describing this is as Applications as a Service (AaaS). Take particular small services such as Apache Camel routes or Apache CXF endpoints and bring them up and down with out destroying the whole application. Apache Karaf IS the platform to do micro services.

To make micro services easier, Karaf provides many helpful features right out of the box;
