I am in a similar situation, the only difference is that I have played with things like networking, docker etc before at work. Honestly 10k INR is not enough in my opinion. You can get refurbished hardware which will be very old, consume more electricity and will not be good performance wise. You will either have to increase your budget or compromise severely on the specs.

Similar thing happened to Burger King in India. Although they still get to keep using the name I guess.

I am in the same situation. I have decided its not worth the time, effort and money to renew it. I have enough industrial experience now that the cert doesn't matter. I still keep it in resume to get past the initial screening where they only check if someone has some certs.

I find Wikipedia to be a great source for learning new topics. I know you asked for videos, but you can still give it a shot. Plus you can take detours while reading about a topic by clicking on links in the article. This gives a more well-rounded understanding IMO.

The dedication to your task is commendable 👏. This is becoming rare day by day.
