The acronym CAD comes from the English expression Computer Aided Design. It involves the use of computer technology to aid in the design of a product. In the case that concerns us now, it would involve designing housings for communications devices. In short, CAD is the drawing or graphical tool that replaces the traditional drawing board in drafting the design object.
If we divide a generic communication system into its most simple parts, we can distinguish four elements: a sender, a receiver, a message to communicate and a medium on which to do so. One of the problems that arises from establishing the communication is access to the medium. When there are multiple users or stations sharing the same communication medium or channel, access control is required to avoid two or more stations transmitting at the same time, which can cause interference and even make the communication impossible.
These days, numerous applications follow a microservices architecture. And many applications manage large amounts of data (user activity on the application, logs, metrics, etc.) that are constantly travelling back and forth between microservices. This can produce a series of problems when it comes to integrating all this information – such as the synchronization, scaling and processing of the data.
Very rarely do leading technology companies and professionals get the chance to see how societal changes impact the core of our business. In this sense, we cannot help but notice how our connectivity paradigms mirror the human sphere of our society. Trends in technology are often influenced by the changes that shape our world and social environment. Here, I would like to take a moment to talk about the late philosopher and sociologist Zygmunt Bauman, who coined the term “liquid modernity” to describe our ever-changing society (characterized by globalization, individualism, and communication and information technologies).
