How do I make an IoT smart clock with multiple apps?

So I want to make a smart clock like Lametric time, with various apps like clock, calender, weather, match scores etc.

I have already made a regular clock with an led matrix and an arduino using an ITC module so I know some C++. But I want to take it a step further. I know I have to use an ESP8266 with wifi to make things work. But I have no idea about the technology stack behind the things. Do I make the arduino process various apps and then render it over my led matrix (I beleive this will be too heavy for a microcontroller)? Or do I use another system like a rpi to run the apps and then send the rendered image to arduino for displaying it on led? I am also thinking about making a web interface to add the apps and extend it to a mobile app later on.

I can do all this but need a starting point to understand what all technologies are used in today's smart devices. I would appreciate any help in getting me started.

Could someone explain? Roles within IoT: IP, ISP, webinterfaces etc.

At the moment I am looking into the more technical side of IoT. I was wondering if someone could give a more clear explanation of the following 'components' and how they relate together. I can not seem to figure it out online:
If you buy an IoT device usually has some sort of web interface to control it. So the device has an IP address, and to this device there is some website (also belonging to this IP address) that runs the webinterface to control the device.
- Who 'runs' this website or webinterface? Is that done on through the device manufacturer, is it through your ISP? Or is it originating from the device and just run on the network of the ISP?
- Who is responsible for keeping this webinterface safe? Depending on who is running the website; is the ISP or device manufacturer responsible?

I am trying to get a clear idea on how this works, and who (generally speaking) has which role. Hopefully someone could briefly explain this to me, that would be very helpfull :)
Thank you.
