Taking a do it yourself approach to IoT data collection.
Gary Stafford has a recent article on IoT Telemetry Collection. He explains not everyone needs to use the dominant cloud providers such as Amazon, IBM and Google but instead can self-build solutions with less vendor platform lockin.
The article provides a hand-on example to transmit the sensor telemetry data as JSON over HTTP and store in MongoDB for viewing in Jupyter Notebooks.
Do it yourself approaches are more suitable for SMEs where scaleability is less of an issue than for large Enterprises. Solutions can be more flexible and on site rather than cloud based for more controllable reliability and security. Costs are also usually easier to determine.
