The best solution that came to my mind is, that we can use AWS storage services to store the seed phrase, I know those services will cost us but, still, the security levels and durability levels are so high in there.
This is not a recommended solution, do not store your seed phrase on any cloud service or online, like I have said, if you store your seed in that way, the risk of it getting hacked and stolen by an attacker is higher than you being affected by an earthquake or a flood.
You are right, the risk is higher in storing them at Online cloud services, but I am talking about AWS storage systems, they have challenged people to hack them in return of hell a lot of money and till now they have not been hacked, maybe once but the data was never gone (means not all data were hacked as it needed more time which Hackers lacks). We can follow some instructions or methods to encrypt our seed phrases and we can then store it on the Online cloud services.
By encrypting the seed phrase with our own keys, we can store it safely on AWS storage solutions, The Point I'm trying to make here is, that we can trust AWS products or Azure services, I even read on Azure's WP that, they will never share any of your information stored in there products with the governments, Until you gave them the permission. I know many people say, they will still share the information behind your back but till now, I am not able to find a single case like that.
PS: BTW what are your plans?
