I would like to know if this network structure it would be viable or not.
The main reason it would be to be able to switch manually, the ISP. If one is going down than use the other one.
as I know public web hosting aren't made to his structure. Eg www.mycompany.com has a dedicated hosting plan somewhere in cloud. At workstations are PC for developers, somewhere it is a Wi-Fi network too for cellphones.
Is there any software, which are doing the automated switching from ISP1 to ISP2 automatically?
Probably I haven't used the networking terms correctly, because lack of deep knowledge, what are the keywords for search?
