frame relay medieval technology ?

in CCNA & CCENT
Starting last semester and its frame relay,now i sort of dont get all the materials go around serial connections x.25 t1 which is basically speeds that most isps provided 10-15 years ago,then theres concept of private lines and public-while i get idea that data center would be using private isp line to support massive bandwidth,but from what i gather so far theres little commands for business to implement frame relay and basically besides setting encapsulation all work is done by ISP end.
Going further whats even the point in paying cash to isps,when nowadays theres services like cloud,even getting few public ips and setting your own server or connection to other branches seems like total no brainer given the cost and speeds one could get.
Correct me if wrong but even if needing direct lan connectivity nowadays its basically application layer on osi model,where most software would be compatible with using some cloud service to exchange or store data or using internal server with nat and acls -so what am i missing in this concept since reading about 1.5mbs lines is a bit cringe worthy,given todays broadband speeds,and options available at fraction of a cost.

What you are missing is that there are a lot of companies and individuals in rural locations (or even urban connections with a poor infrastructure) that cannot achieve even 1Mbsp connectivity. Given the cost of upgrading the infrastructure to these locations, it is not going to be upgraded anytime soon, so in the real world you need to support such customers who remain on the distant end of an old, wobbly copper cable.

That aside find it a bit strange since asked lecturer,and way he explained even if getting frame relay basically 99% will be done by isp and contractors-sorta included in the cost.did the lab in its sorta cool to see two remote networks but again dont think two sites that would have few mbs line would be in positions where it would be viable cost to do it rather then using alternatives.
I'm not an expert on knowing what a person working in the networking field needs to know. But, if employers didn't think the cisco certs were relevant, they wouldn't care if anyone had them.
Since for frame-relay it just puzzles me why speeds are so outdated,with current BB options in curriculum.
Also, to get technical, frame-relay is a layer 2 technology. Which may be a deciding factor depending on what an organization needs from its network.

While a Metro Ethernet connection would definitely be more costly than frame relay, you would get a much larger bang for your buck, or if you are really close to a telecom CO, you could get ethernet over copper with okay speeds. With that said, there are still companies using frame relay or T1 lines as backup circuits, or they are used to route VOIP traffic between sites.
Getting fiber connectivity to some locations are just not financially feasible. I've done estimates and they can easily reach 6 figures. We would need to review the ROI to see if it's worth building. That's why a lot of sites are stuck with T1s but that's fine for a lot of sites. They can bundle T1s if they want a bit more bandwidth.
