Neo4J is the most popular graph database in the NoSQL databases family. We’re using it in the Nousmotards project to store all social data through nodes and relationships. Today I am going to talk about our experience after having using it for 2 years now (take a look at directed graph if you are not really familiar with Graph Database). 1/ Our use case Nousmotards is a social network for bikers, we aim to provide valuable tools to ride, meet and share nice time with people who like motorcycling.

The Ansible meetup ended ! That was really nice for my first one. I had really great feedbacks and liked the questions when ended.

For a new project (will talk about it later), I needed to use Neo4J (graph database if you don’t know it yet). I tried to cover more features than the current existing Ansible roles available on Ansible Galaxy. More will come in the next weeks. I also tried to make it simple to install it and do not force dependencies at maximum. Here are parameters you can set: # Select neo4j version neo4j_package: neo4j # community version #neo4j_package: neo4j-advanced #neo4j_package: neo4j-enterprise # Neo4j spatial plugin neo4j_install_spatial: false neo4j_spatial_version: '0.

During the last weeks I started to play with Elasticsearch, Fluentd and Kibana. I made a documentation to help on deploying it easily. As you may know, I’m an Ansible fan, so I made Ansible playbooks to deploy a complete infrastructure (server and clients). They will deploy this kind of architecture: On the client side, Fluentd clients will get syslog and Nginx logs, to send them to the Fluentd server. On the server side, a Fluentd receiver will be there to get data from other Fluentd clients.
