So I have quickly put together a list of resources, more specifically podcasts, blogs that I consume regularly… This is no way a definitive list 😉 and in no particular order!

Azure Container Services (AKS)
In a nutshell, Kubernetes is a container orchestration tool that enables container management at scale. Kubernetes isn’t a replacement for Docker.

This post describes how to ingest sample real time streaming data from PubNub to a Postgres database with the TimescaleDB extension installed and enabled for time series analysis. I wrote a small Node.js app to test and demonstrate how TimescaleDB performs well in fetching results while data is also being ingested in the database. Will be using the following data feed, Market Orders – an artificial data stream that provides the latest market orders for a fictitious marketplace and you can clone or download the GitHub repository from -> https://github.com/sfrechette/stream-sequelize-node. The Market Orders data feed generates on average 4 inserts per second, if you would to ingest more inserts per second I recommend you look at the following data feed Sensor Network which generates on average 10 inserts per second.
