Some of the things that need to be talked about include high-density. CPU and even the server capacity performance needs to be continually increasing as the evolution of IT carries on growing. As the demand for AI applications increases, the importance of computing power grows as well. If you want to balance things out then you need to make sure that data centres are able to develop with a very high density in mind. The average power capacity for a data centre is currently 6-8kW a rack. It's expected to double by the year 2025. If you work in a data centre recruitment agency for data centre jobs then you will know how interesting this is.
Generally, the lifespan of any IT device is between 3-5 years. The power density of course, doubles every five years as well. The data centre facility supports IT evolution for two to three generations. This demands a scalable expansion and it also means that more needs to be done to try and make sure that everything is optimal in general. Only time will tell what the future is going to hold but right now it looks like everything is being done to make sure that things are future-proofed.
