Designing for high availability and fault tolerance in the cloud involves several key strategies. Redundancy is crucial, achieved by deploying multiple instances of resources across different zones or regions to ensure service continuity if one fails. Load balancing helps distribute traffic evenly among these instances, preventing overloading and potential failure. Auto-scalaling adjusts resource allocation based on demand, ensuring optimal performance while minimizing costs. Regular backups and disaster recovery plans are essential to quickly restore services after a catastrophic event. Monitoring systems provide real-time insights into system health, enabling proactive issue resolution before they escalate into failures.
