SaaS has been a success in the same way "bring your own device" was a success - an end-run around the ossified, slow-moving and bureaucratic ICT department. It was nimble, fast and elastic; allowed for quick iteration and experimentation. Now that the SaaS is a big game, it's subject to the very same kind of disruption.
Take a look around, you'll see people using local Git repositories, and locally hosted web-based services to get shit done. Just to avoid the hassle of procurement & upkeep of big-name SaaS. Containers let you move the data & code to unmanaged iron where it's close to the user, instead of one big managed datacenter. SaaS and datacenter computing is not nimble anymore; local is nimble, and Google Stadia delivered the eulogy.
