Hands-On Industrial Internet of Things

Comparing the platforms

Let's conclude our discussion by comparing the discovered platforms. To evaluate a platform, it is important to take the specific use case into account, but there are three general key points that we should consider:

• Does the data model conform to how we acquire data?
• Does the support for analytics conform to our needs?
• Are the supported devices suitable for our use cases?

In the I-IoT, we acquire data when it changes, so we may need interpolation functions to fill the gaps, as we discovered with the OpenTSDB and KairosDB open-source databases in Chapter 8, Implementing a Custom Industrial IoT Platform. It is important to consider whether for our particular context it is more appropriate to use an analytical cold-path ...
