As a systems administrator for the past 15 years, I’m not very used to web development as this kind of work has been usually done by other colleagues in every company I’ve worked for. I wanted to create a web application myself using an external API, as an exercise to go out my comfort zone.

The IoT industry has been running for some years now adding millions of devices into the network. The range of devices and capabilities is very wide and heterogeneous, from small devices powered with a 9-volt battery to track the location of freight shippings traveling the oceans (using platforms like Sigfox) to permanently plugged devices with more powerful computing like a Raspberry Pi where computation cycles are not a problem. Generally speaking, all these devices collect raw data and send it to the cloud where big data centers process it.

The more we talk to people about API gateways, the more we have come to realize that the term means different things to different people, and more specifically we see a growing trend where developers (but mostly managers) expect an API gateway to be able to perform miracles, usually a long way away from its intended use. It’s as if the API Gateway is the new unicorn that will solve all problems and make everything wonderful in the microservices scene.
