As a former head of engineering for a mid-sized IoT company with many tens of thousands of devices deployed in the field using a competing product (no, not the AWS one), seeing this made my stomach churn.
This was my second biggest fear after waking up to a ransomware attack.
It's hard to imagine anyone trusting Google for IoT again. I will certainly put them at the bottom of my list for any other infrastructure I develop against in the future, and ensure that we have a documented exit strategy should it come to pass.
The idea of having just one year to develop against a new IoT core, test it, update all deployed devices, and then coordinate logistics and budget to do truck rolls when things invariably go wrong is really grinding my gears.
I feel for all of the startups having to deal with this. To the folks who are invariably scrambling, I really hope you either got advanced notice, or you're getting an extension far beyond what is publicized. Edit: The more I think about this, the more I want to believe there must be contracts in place for certain customers that extend the lifetime of this product beyond what is public. There must be.
IoT is not an easy business. Designing and programming hardware is hard. Supply chains are hard. Maintaining working inventory is hard. Building logistics networks for installation and maintenance is hard. Courting and explaining to investors why you don't have the profit margins of a pure SaaS business is hard. Relying on your cloud provider to give you more than 1 year notice should be the easy part.
