Availability management
Making sure a service is available as reliably as the business needs
What's it for?
Helps keep important services working and reduces how often they are unavailable.
For example…
A critical payments service is built active-active across two sites to meet a high availability target.
Availability management identifies a single database server as a weak point and adds a standby so one failure does not stop payroll
Think of it like…
Keeping the lights on in a hospital ward: redundancy and maintenance planned so care does not stop
