A few weeks ago it was the hackathon onpe in my country (Peru). The problem was the intercommunication between different identities of the government to transport safe documents (with digital signatures) and track it. My team came second with a solution of websockets in nodejs + mongo db, allowing the sending of information encrypted with public / private keys in real time and consultations (tracking) through a web app.

The winning team presented a blockchain solution (which until then was unknown) + chatbot for tracking, as if to take off their hats and applaud. So there I thought, there's a lot of what I do not know in cloud technoloy, so I ask you if you know any good cloud computing / technology forum to find out how much I do not know and keep learning.

PS: I would like to know your thoughts on the winning solution   

Thank you for reading,
