From Mainframes to Containers

A few days ago, Stevie Chambers tweeted about the evolution from mainframe to container: “Why is it a surprise that VMs will decline as things miniaturise? Mainframes → Intel → VMs → Containers, etc. Normal, I’d say.” By “Intel” here, I’m going to take Stevie to mean “rackmount servers.” I’m also going to assume that by “decline” he meant “decline in importance, or focus” rather than decline in raw numbers of units sold. It would be easy to argue that there have been fewer rackmount servers sold in the last few years than would have been the case without virtualization, due to the consolidation of servers onto fewer, more powerful boxes. It’s also arguable that virtualization has brought us options that would simply be unavailable without it and have led to more volume of sales. Either way, Intel’s profits seem to be doing ok.
