The Cost of Data (RailsConf 2021)

The Cost of Data (RailsConf 2021)

The internet grows every day. Every second, one of us is making calls to an API, uploading some images, or streaming the latest video content. But what is the cost of all this?

Every day, a data center stores information on our behalf. As engineers, it's easy to focus on the code and forget the tangible impact of our work. This talk explores the physical reality of creating and storing data today, as well as the challenges and technological advancements currently being made in this part of the tech sector. Together, we'll see how our code affects the physical world, and what we can do about it.
