Cfmap: Publishing, discovering and dashboarding infrastructure state

Dynamic infrastructure can be a challenging if apps and scripts can’t keep up with them. At Ingenuity we observed this problem when we started moving towards virtualization and SOA (service oriented architecture). Remembering server names became impractical, and error-free manual configuration changes became impossible. While there are some tools which solve parts of this specific problem, we couldn’t find any opensource tool which could be used to both publish and discover state of a system in a distributed, scalable and fault-tolerant way. Zookeeper which comes pretty close to what we needed was a fully consistent system which was not designed to be used across multiple data centers over high latency, unstable network connections. We wanted a system which could not only be up during network outages, but also sync up the state from different data-centers when they are connected. We built a few different tools to solve our scalability problems, one of which is a tool called Cfmap
