What are the best technologies for active-active configurations?

What are the best technologies for active-active configurations?

Active-active configurations allow multiple systems to run simultaneously, enhancing availability and load balancing. Key technologies include database clustering, load balancers, and distributed file systems.

Can you explain how database clustering works in this context?

Database clustering involves multiple database servers working together to provide high availability and redundancy. If one server fails, others can take over without downtime.

What are some popular load balancers used in active-active setups?

Popular load balancers include NGINX, HAProxy, and F5 BIG-IP. They distribute traffic across multiple servers to ensure no single point of failure.

Are there any specific challenges with active-active configurations?

Yes, challenges include data consistency, network latency, and the complexity of managing multiple active nodes. Proper planning and tools are essential.
