In this tutorial we will setup a Distributed Database with Docker Containers. OrientDB distributed concept is a Multi-Master topology. We will split of a class in three logical clusters and store each cluster on two servers. In this way we improve the reliability and the scalability of our system.

On the OrientDB manual sites the basics to understand how a distributed system works are already well explained.

In this book we will create an implementation, similar to the example in the OrientDB doc's.

This may help you understand and test the capabilities and the limits of such a distributed database.

For setting up some DB-Servers on the same sub-network there are many possibilities, for example using virtual machines. In this tutorial we will use Docker, since it will not generate so much overhead as a fully virtualized operating system. In a Docker-Container only the needed processes are running, therefore not so much computing capacity is needed.

If you have never heard about docker, or if you interested, read the well made docker docs.
