Kibana 5.5 is out, and there is a nice new visualizer that lets you colorise a full country depending on the value of the record. It is really interesting for me as I developed such a plugin because I required the exact same functionality here.
Elastic search released the latest version of its stack. There are of course a lot of cool new things, but we also feel that they, one step after the other push people to a licence model. I have no problem with that but it makes the life of people that want to keep a licence free stack more difficult.
Node red is a really nice framework that lets you build IoTs workflows. It is in fact far more interesting than that because you can use it in order to create small workflow integrations as you would do with a product like Mule or Camel. Of course you should not use it if you want to handle critical financial messages using a MQ Series transaction but it can handle most of the less critical cases.
Creating a REST API is one of the building block of lot of software. It lets us access to data using an easy protocol accessible by most of the recent programming languages. That’s great but which language should we use to build the API.
We will once again use docker to deploy a fully functional stack of InfluxDB and Grafana. I was a little bit disappointed by the lack of free options to scale the InfluxDB horizontally but however, it is still a nice product when it is deployed in a single server.
