A XaaS Savvy Automated Approach to Composite Applications

Applications have evolved significantly over time - from monolithic and self contained, to numerous plug gable apps available on various platforms these days. Modern applications their functionality as services in varying level of granularity and domains. This paradigm of Everything as a Service (XaaS), provides a dynamic environment wherein multiple smaller applications can be rapidly composed to create complex applications. Such composite applications would allow for efficient re-use of the existing applications and their services, instead of more traditional model of building everything from scratch. The intent of this paper is to demonstrate our initial work to implement an end-to-end delivery system in an enterprise scenario. We propose an automated algorithm to utilize a composer's input to match available services and create a composite plan or a manifest which is then used to quickly orchestrate the composite application in real-time. We have implemented our approach on our internal enterprise cloud using Puppet.
