Define 'active-active' configuration in L3W storage solutions.

An active-active configuration refers to a system design in which multiple data centers or storage nodes are running simultaneously and handling requests at the same time. This setup significantly enhances availability and reliability because if one data center encounters an issue, the others can continue to operate, thus ensuring continuous service availability.

In active-active configurations, load balancing is typically employed to distribute workloads evenly across all operational sites. This not only improves performance by allowing more transactions to be processed concurrently but also enhances redundancy. In scenarios of geographical distribution, this design can offer localized access to services, reducing latency for users.

This model stands in contrast to alternatives, such as an active-passive configuration where only one data center is actively handling requests while another remains on standby, ready to take over in case of failure. Other options that focus on batch processing or prioritizing data syncing do not encapsulate the core principle of continuous and simultaneous operation that defines an active-active setup.
