This document discusses Algar Telecom's Coreo platform, which is a dynamic platform for composing telecom applications. It outlines Coreo's architecture, which uses messaging passing and stateless storage to allow distributed and scalable apps. Some lessons learned include the importance of data-driven decisions and adapting legacy systems. Challenges include effectively using big data and dealing with existing telecom platforms. Overall, Coreo aims to enable telecom innovation through a platform built on open source WSO2 tools.
