Crash Fault Tolerance vs High Availability
Developers should learn and implement CFT when building distributed applications, such as financial systems, e-commerce platforms, or real-time data processing, where high availability and data integrity are critical meets developers should learn and implement high availability for critical applications where downtime can lead to significant financial losses, reputational damage, or safety risks, such as in e-commerce platforms, banking systems, healthcare services, and telecommunications. Here's our take.
Crash Fault Tolerance
Developers should learn and implement CFT when building distributed applications, such as financial systems, e-commerce platforms, or real-time data processing, where high availability and data integrity are critical
Crash Fault Tolerance
Nice PickDevelopers should learn and implement CFT when building distributed applications, such as financial systems, e-commerce platforms, or real-time data processing, where high availability and data integrity are critical
Pros
- +It is essential for ensuring that systems can recover from hardware failures, network partitions, or software crashes without data loss or service disruption, often using techniques like replication, leader election, and state machine replication
- +Related to: distributed-systems, consensus-algorithms
Cons
- -Specific tradeoffs depend on your use case
High Availability
Developers should learn and implement High Availability for critical applications where downtime can lead to significant financial losses, reputational damage, or safety risks, such as in e-commerce platforms, banking systems, healthcare services, and telecommunications
Pros
- +It is essential in cloud-native and distributed systems to handle failures gracefully, ensuring resilience and reliability, and is often required in service-level agreements (SLAs) to meet customer expectations for uninterrupted access
- +Related to: load-balancing, failover-clustering
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Crash Fault Tolerance if: You want it is essential for ensuring that systems can recover from hardware failures, network partitions, or software crashes without data loss or service disruption, often using techniques like replication, leader election, and state machine replication and can live with specific tradeoffs depend on your use case.
Use High Availability if: You prioritize it is essential in cloud-native and distributed systems to handle failures gracefully, ensuring resilience and reliability, and is often required in service-level agreements (slas) to meet customer expectations for uninterrupted access over what Crash Fault Tolerance offers.
