In 2017, Google made the first official announcement that they wanted to get involved in the competitive market of the Internet of Things, and introduced a new IoT core service. It enables connection of devices via the MQTT protocol or HTTP to the Google cloud, and offers direct links to services such as Pub/Sub and Google cloud Dataflow. Shown below is an example of an architecture for data analytics with IoT data in GCP.
After about five years, Google informed its customers in August last year that the offered IoT core service would be shut down and they would have to find an alternative by 16th August this year. A comparison of Google's IoT portfolio with that of its direct competitors such as Microsoft Azure or Amazon web services quickly reveals that the offer in Azure or AWS is much more extensive than Google's was. It therefore stands to reason that Google decided against making a larger investment in the IoT area, which would have been necessary to reduce the disparity with the competition. With its decision, Google is pursuing a different strategy than its two direct competitors, and relying on cooperation with partners as well as IoT platform providers. As a result, the enterprise reduces its risk and focuses more on its lucrative core business involving data platforms and analytics.
From Google's point of view, this step is understandable. However, customers who rely on Google's IoT core are faced with the question of how they can replace it with something equivalent.
