How to host a website on two hosting accounts?

Question

Domain Name System

I have a website on one hosting, but due to the corona virus, the hosting may be covered. There is a second hosting.
It is necessary to make sure that if one hosting fails, the second one can take over the function of the main one.
If such a possibility? terms or links will help a lot.

Answer 1

Answer 2

Hire an administrator, he suits you with fault tolerance, redundancy, replication and all other terms that will not help without general knowledge.

Answer 3

at least it’s expensive
if you don’t have money except for deshman hosting, just make backups and deploy them on a new hosting, it will take half an hour after turning off the first one

Answer 4

1 Yandex cloud, there is a balancer
2. www.cloudflare.com - dns deligirish through them there is a balancer, and conditions, etc., etc.

Answer 5

If it’s stupid: you need to duplicate all changes in the database on two sites and register two IP-shniks from different sites with different priorities in DNS for one domain.
As soon as the main hosting stops working, another one will immediately continue to work.
But after raising the main one, the procedure for cloning the database "up" will be needed.
