System considerations for architectural design
Now that we have a fair understanding of architectural principles and patterns, we would like to explore some key considerations that help drive architectural decisions. These are listed across the edge and cloud in Figure 9.11.
Figure 9.11 – System considerations
We have a clearer view of the edge and the cloud in moving decision-making’s compute power and autonomy near the assets or to a central system. Bandwidth plays a very important role in system design.
As we know, the volume of data generated in the OT layer at the machines and sensors is very high and keeps compounding. Still, since most shop floor locations are remote areas with no access to high-speed internet, data transmission becomes a challenge. A strong edge with a higher storage capacity is recommended in these scenarios. We can then adopt a store-and-forward approach for the computed results or filter and forward to only...
