IOTFRIDAY E13 | Edge Computing to Battle 50,000 Messages per second

Data becomes an issue

Online data storage is cheap and cloud computing power is widely available. This creates the situation where IoT solutions send all their data to a cloud platform before analysis starts. Why not have all this great data available? A problem rises where data streams become too big. This can be a costly adventure (paying per byte will get expensive). It is also causing high loads on the cloud end of the IoT solution. Availability of services floats towards the danger zone. In comes edge computing!

Edge computing

With edge computing, the local computational power is used to (pre-) process data. Local analysis is done before communicating this to the cloud. Even a shift from cloud applications to local applications is possible. Edge computing is literally computing data at the edge of the network.

Always edge computing?

The shift can be made towards the tiny end of the IoT solution (for example a sensor with local storage) but also a combination of things with a gateway does an analysis of data before sending it to the cloud platform. Take 1000 sensors in a factory transmitting messages 50 times per second and there are 50,000 messages per second. Only for one type of sensor! Edge computing can create a situation where all the data samples are averaged locally and then sent. It reduces the data stream by factors. Edge computing solutions are potentially advantageous but also have their downsides.

This webisode of IoT Friday gives insight into edge computing, pros and cons, and insight in the position within IoT solutions. To watch all the previous webisodes, go to our Youtube Channel and don’t forget to subscribe.

About

Tom van de Ven is active in the field of High Tech testing for 15 years. As a High Tech test expert he is a frequently asked sparring partner for Sogeti High Tech customers with regard to starting/professionalizing test projects. Besides a multitude of test assignments (eg. in the field of healthcare, semiconductors, agriculture and automotive) he is an active member of the Sogeti High Tech Test Competence Centre and a speaker for High Tech seminars. Tom uses his experience in a role as a coach for (starting) High Tech test engineers and is constantly looking for improvements in High Tech test methodologies. He is the author of the book that combines Internet of Things and TMap: IoTMap!!!. He also teaches and develops several testing courses in the embedded and high tech domain. If not teaching, testing a tunnel or promoting “Quick Tech Testing” you can find him setting up a high tech test automation framework for the odd customer.
