The world is full of good surprises.
If you joined the NoSQL gang like me, chose Cassandra to store your data and you distributed your system among different datacenters. Wouldn’t it be great to interconnect all your nodes on a virtual private network with no single point of failure? Well, TINC does just that. In fact, it does a little bit more because it’s able to establish a meshed network if hosts can’t directly contact each other (in case of a routing issue, a NAT firewall, etc).
One of the amazing things about this software is that it’s really simple to setup. I followed some setup instructions and it just worked. I didn’t have to increase the verbosity or check any log, it just worked everywhere.
