I'm a SysAdmin in one of the construction sites in a remote place. There is no reasonable internet speed can be reached there except a poor 3G/4G signal coverage which provide the users with non-stable average speed of 1 Mbps.
We have a web-based internal system and um wondering if I can use the high availability (Clustering) solution to make that system available offline (locally) to all the users in case the internet can't handle it. Then, give the whole bandwidth to the router to sync the content with the main server which is located in another country.
Hint: I'm imagining the same idea like Active Directory Replication.
Also, What about the content engine? is it the same idea like HA or gives more advantages?
