Designing a system to remain accessible even if individual components fail. Uses redundancy, monitoring, failover, replication, and recovery procedures.
Why it matters
Ensures that the failure of a single component does not bring down the service — backup servers take over traffic before users notice anything.
What's missing without it
Without redundancy, a single disk, process, or network failure can bring down the entire service — and failures always happen at the worst possible time.
When it is used
Used for services where downtime is costly: ad portals, e-commerce stores, email marketing systems.
How we use it
A second API instance and a database replica minimize downtime after a single server failure.
