Single Active vs Active-Active
Developers should learn and use Single Active when building fault-tolerant systems that require high availability and minimal downtime, such as in financial services, e-commerce platforms, or critical infrastructure meets developers should learn active-active for building resilient applications that require minimal downtime and high throughput, such as e-commerce platforms, financial services, or real-time data processing systems. Here's our take.
Single Active
Developers should learn and use Single Active when building fault-tolerant systems that require high availability and minimal downtime, such as in financial services, e-commerce platforms, or critical infrastructure
Single Active
Nice PickDevelopers should learn and use Single Active when building fault-tolerant systems that require high availability and minimal downtime, such as in financial services, e-commerce platforms, or critical infrastructure
Pros
- +It is essential in scenarios where multiple instances could cause issues like duplicate processing or race conditions, such as in leader election mechanisms, job schedulers, or distributed locks
- +Related to: distributed-systems, concurrency
Cons
- -Specific tradeoffs depend on your use case
Active-Active
Developers should learn Active-Active for building resilient applications that require minimal downtime and high throughput, such as e-commerce platforms, financial services, or real-time data processing systems
Pros
- +It is essential in scenarios where single points of failure are unacceptable, enabling automatic traffic redirection during failures and efficient resource utilization under varying loads
- +Related to: high-availability, load-balancing
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Single Active if: You want it is essential in scenarios where multiple instances could cause issues like duplicate processing or race conditions, such as in leader election mechanisms, job schedulers, or distributed locks and can live with specific tradeoffs depend on your use case.
Use Active-Active if: You prioritize it is essential in scenarios where single points of failure are unacceptable, enabling automatic traffic redirection during failures and efficient resource utilization under varying loads over what Single Active offers.
