I have two identical servers, they run linux and they have a data base and a piece of software that is constantly recieving inputs. What is the right term that I should search for to be able to configure one as a redundant server - I mean when one fails the other one takes the job from where the first stopped.

Is it high availability the term that I am searching for? - Really new to this, so please help me.

    What kind of results did you get when you tried googling it? That will tell you whether the term was right or not. – Jenny D Mar 15 '19 at 12:37

Pacemaker will provide high availability for database and software. But to avoid split-brain you will need 3rd device as a witness (it can be even Raspberry Pi).

You can start with this link: https://clusterlabs.org/pacemaker/

high availability is the closest term to what you describe.

Also, depending on the software solution you will end up with, you need to look at things like active-passive or active-backup configuration, which just means you have servers dedicated for the load and servers doing nothing, but available in case the active one fails. This is to differential with active-active configuration which is interchangeable with load balancing.

Possible search terms would be:

Load-Balancing

Disaster Recovery

Horizontal Scaling

These terms describe some of the aspects that you're looking for mainly disaster recovery.
