Imagine remotely controlling our home’s devices from our smartphone – this amazing convenience is powered by web services, invisible messengers seamlessly connecting our digital world.
Web services form an integral part of today’s internet infrastructure. They allow for the seamless exchange of data between different software applications over the internet. As a result, they are an essential tool for IoT applications, including our Raspberry Pi IoT projects. With web services, we can draw on the wealth of data available online and bring it into the physical world using our Raspberry Pi.
At their core, web services are software interfaces that enable one software system to interact with another over a network. This interaction is typically done via specific protocols, such as Representational State Transfer (REST) or Simple Object Access Protocol (SOAP).
