In the early days of software development, anyone seeking to develop a web, mobile, or backend application had to own the hardware required to run a server, which is an expensive process.
Then, when cloud computing came, it became possible to lease server space or a number of servers remotely. The developers and companies who rent these fixed units of server space generally overbuy to ensure that a spike in traffic or activity won’t exceed their monthly limits and break their applications. Because of this, a lot of the server space that gets paid for can be wasted.
