Availability & Reliability
Design highly available systems with redundancy, failover, and graceful degradation.
Design highly available systems with redundancy, failover, and graceful degradation.
Understand the fundamental trade-offs: Consistency, Availability, Partition tolerance, and how PACELC refines these choices for modern systems.
Prepare for disasters with recovery planning, backups, and restore procedures.
Distribute read traffic across replicas while maintaining consistency
Build resilient systems through redundancy and automatic failover.
Deploy across multiple availability zones within a single region for high availability, fault tolerance, and synchronous data consistency without multi-region latency penalties.
Choose between synchronous request-response and asynchronous messaging. Understand coupling, latency, and availability trade-offs.
