IT has definitely change over the years. I'm trying to enjoy my freelance IT admin niche while I still can, because more & more cloud service provider companies are getting things figured out, to the point where you can pay for a cloud PC & just have a thin client, have cloud servers, cloud phone systems, and not really require on-site IT services because everything is so turn-key. It's like Google Stadia for video games or Netflix for movies, but for IT infrastructure. It's a fun niche & I get to do all kinds of unique projects, but especially with how good cloud virtualization has gotten & PCoIP has gotten & how 5G is starting to pop up everything, things are in for another major shift in the industry, imo.
I could foresee Amazon offering a small-biz package like this...a bundle with VOIP, electronic faxing, branded email services, thin client cloud computers, an easy interface for controlling file-server permissions, etc., so that you could just buy the basic hardware & pay for what you need on a month to month basis. Microsoft has already done it with their Office 365 online system, at least for the Word/Excel/etc. package. Plus I already do this for finances at a lot of small businesses, especially my food-industry customers...Square, Toast, Clover, etc. all make super-easy systems, you can track everything easily with QuickBooks Online (even from the beach!), so it'd just be the next turn-key, monthly-payment cloud offering to simplify things even further. Things have gotten waaaaaaay easier over the years!
