Learn about virtualization, its benefits, and cloud management platforms.
As the hardware costs decreased, servers became more powerful. Processors were developed with multiple cores, so a single chip could have between two and sixteen CPUs. Memory became cheap enough to pack a full terabyte or more into a single server. All this additional processing and memory capacity made virtualization possible, which changed the relationship between an operating system and a server.
Suppose we were to go to our computer and run a simple program, such as a text editor. Now, do it five more times. We now have seven instances of that program running, all at the same time.
