How do i take logs & analysis about how my web application is performing.
You can kinda make this as complicated as you want though. Elasticsearch is an alternative to loki that (in my experience) is much much more effort (and money) to run, but it can scale much farther than loki can and offers more powerful types of searches that you can do. Yet another option would be to ship everything into a managed solution like aws cloudwatch and let them handle it

Oh and in terms of getting notified: i'm pretty sure these days grafana has pretty good support for setting alert threshholds these days. I haven't used it for alerting before for that, but I imagine you can configure it to send webhooks to wherever you want (a discord channel or a pagerduty alert would be common options, depending on how hard you wanna be notified)

Again though, what makes the most sense for your situation will depend quite a bit on what your infrastructure is like. If you're on k8s you might also want to look into a service mesh like istio, which can simplify quite a bit of that complexity

logging/telemetry is obviously a very big topic & there are a lot of different completely valid tech stacks. Part of it will depend on how you're hosing your project, is it kubernetes/vercel/docker containers running on a host/raw dogging systemd services? IMO the bare minimum is having a single place to look at logs. If you're running microservices replicated across multiple nodes, having to shell into each node and tail logs is pretty miserable. Again, there are a lot of tech stacks that solve this problem, but one decent option is using grafana for building dashbards & browsing logs, grafana loki as the database that basically holds your logs, and fluentbit running on your workers to tail the logs and ship them to loki. To get metrics (things like CPU/memory/requests per sec/latency/failure rate/etc) prometheus is a very popular option. You mentioned open telemetry, which is a standard for propagating metadata along with a request as it moves through the distributed system. The most common example is having a request id that gets assigned when a request enters your system, and then all the logs on the backend having to do with that request (even if handling the request involves multiple backend services) will all automagically get tagged with the request id. Then you can just search in grafana for a request id and see all the logs from all the services having to do with that request. Open telemetry (afaik) is just a standard for passing that data from service to service using http request headers (or equivalent if you're not using http). You'll need to ship that data somewhere for it to be useful. OpenZipkin and Jaeger are the 2 most popular solutions afaik

Google drive as file storage
Disclaimer that I haven't done much with the google drive APIs so I might be ignorant of some hack to make the auth do what you want. That said, my guess is that google probably doesn't support quite what you want. So instead of having the client on the kindle directly connect to google drive (requiring that it log into google, by the sound of it), my suggestion would be to have your server present its own CRUD endpoints, and then the server can use a client secret (or whatever OAuth flow makes sense) to interact with google docs on the backend. Basically like how a normal database would work: you don't give the client direct access to your postgres db, instead you give your server access using a secret and then your server acts as a middle man between the DB (in this case google docs) and the client. Then you're completely free to do the authentication (or lack thereof) between the client and your server however you want.

Is it necessary to have backend to upload pdfs, in uploadthing ???
These uploadthing docs have pretty good guidance about how to implement your own backend endpoints if they don't support the language you need. It seems like you just need to implement GET/POST /api/uploadthing endpoints on your .net backend, and then you should be able to get uploadthing working

dockerhub storage problem?
It looks like public dockerhub repos are still free, so if you're hosting OSS stuff then I think you're fine. For private repos, I've used AWS ECR for the most part and been very happy with it. It has quite a lot of support for automated cleanup of old images, and if you already are using AWS then authenticating with it is pretty strait forward. The pricing is also quite reasonable IMO. I imagine GCP/Azure probably have similar offerings as well, but I've never used them so idk the details

Couple Apache Question
The world of enterprise java java EE jakarta EE frameworks is a bit of a tangle to figure out. I think the wiki page on servlets is a very good place to start getting an understanding of where tomcat fits into the bigger technical picture

Couple Apache Question
Actually, I just tried that (it's been a while since I've used tomcat) and it turns out for "security reasons" they made it a little more annoying to get the admin dashboard going. Turns out after you start the container you've gotta run a command inside the container to enable the dashboard. So to make that work you've actually gotta: 
docker run -it --rm -p 8888:8080 --name my_tomcat_container tomcat:9.0
docker run -it --rm -p 8888:8080 --name my_tomcat_container tomcat:9.0
to start the container, and then to actually enable the dashboard you have to deploy the dashboard. There are prob a couple ways to do it, but this is one: 
docker exec -it my_tomcat_container sh -c 'mv /usr/local/tomcat/webapps.dist/* /usr/local/tomcat/webapps/'
docker exec -it my_tomcat_container sh -c 'mv /usr/local/tomcat/webapps.dist/* /usr/local/tomcat/webapps/'
More info about this extra wrinkle here. Understanding the thinking behind why they chose to make this change might be good prep for an interview ;)

Couple Apache Question
is it possible to deploy and an Apache instance within a VM, and if so help on how to do it is appreciated
A docker container isn't quite the same as a VM, but I think it's probably what you want in order to get started easily. Assuming you've got docker installed on your computer (if not, you should google how to install it), you can start tomcat with docker run -it --rm -p 8888:8080 tomcat:9.0 (source), and then if you open http://localhost:8888 in your browser you should see the tomcat dashboard

Couple Apache Question
Hey! I think you're getting (understandably) tripped up between Apache Foundation and Apache Server. Apache Foundation is a not-for-profit that organizes and financially supports a bunch of extremely popular open source projects. The projects that are supported by the apache foundation are prefixed with the Apache name, and are sometimes written by the same group of devs (maybe always, I'm not sure about that part). These projects span a huge range of technologies, and many have developed great reputations for being extremely solid pieces of tech. Here's a handy list of all their projects. One of their most popular such projects is the Apache Server (which is, you guessed it, a server runtime. Kinda like Node, but for Java). There's another (completely unrelated) project called Apache Tomcat which is also a server, but it's written in java and is designed to run as part of the Enterprise Java stack, which is about as fun as it sounds. Yet another project is Apache Ant, which is an alternative build system compared to Maven. It's vaguely like a java version of esbuild (I think... I've admittedly never used it). Another competitor in that ecosystem is gradle, if you want yet another thing to look into ;)

Integrating uploadthing with REACT + VITE
How are you hosting/deploying your app? My understanding is that uploadthing relies on having a server that can handle webhooks/callbacks and secret keys, so if you're deploying your react app as static files via a CDN, then I don't think upload thing will work for that usecase
