Part 2/10:

Resilience refers to a system's ability to continue functioning, even when parts of it fail. While startups might initially focus solely on core functionality, as they scale, resilience becomes paramount. Recent incidents underscore this necessity:

• UPI Outage: A few months ago, a UPI system failure caused downtime that disrupted millions of transactions.

• CrowdStrike Outage: A technical problem grounded hundreds of planes and resulted in massive financial losses exceeding $500 million.

• Facebook Downtime (2021): Even the tech giant's outage led to an estimated loss of $300 million in ad revenue and reputation damage.

These examples highlight that no system is immune to failure, but the impact of outages can be mitigated with resilient design.
