Systems Analyst: What is the difference between active-active and active-passive?

Active-Active — all nodes handle traffic. Active-Passive — one node handles traffic.

Active-Active:

• All nodes active.
• Handle traffic simultaneously.
• Better performance.
• Higher complexity.

Active-Passive:

• One node active.
• Others on standby.
• Failover on failure.
• Simpler.

Key differences:

• Active-Active — all active.
• Active-Passive — one active.
• Active-Active — better performance.
• Active-Passive — simpler.
