How do load balancers help in scaling applications?

Load balancers distribute incoming traffic across multiple servers, ensuring no single server is overwhelmed. This helps in scaling applications by improving performance and reliability.

What are the different types of load balancers?

There are mainly two types: hardware load balancers and software load balancers. Hardware ones are physical devices, while software ones are applications that run on standard servers.

Can you explain how a load balancer improves fault tolerance?

Certainly! A load balancer can detect server failures and reroute traffic to healthy servers, ensuring continuous availability and minimizing downtime.

What factors should I consider when choosing a load balancer?

Consider factors like scalability, cost, ease of configuration, supported protocols, and whether you need a cloud-based or on-premises solution.

Are there any specific load balancers you recommend?

Popular options include AWS Elastic Load Balancing, NGINX, and HAProxy. The best choice depends on your specific needs and infrastructure.
