Part 3/10:
Can We Achieve 100% Resilience?
It's important to recognize that no system can be entirely invulnerable. All systems are doomed to fall eventually. The goal, therefore, is reducing the impact and containment of failures. For example:
Netflix manages thousands of microservices daily, deploying updates constantly. Their system is designed to fail gracefully and recover automatically, preventing total outages.
High-Resilience Systems like SWIFT (banking), Amazon Web Services, and stock exchanges demonstrate that with careful architecture, system failures can be contained without catastrophic results.
The key lies in designing architectures that can "fail gracefully," where failures don't cause system-wide collapse.
