Technical Interview Prep: Load Balancers

Load balancers: what are they?

Load balancers help the system maximize capacity and reduce wait times by distributing incoming traffic. Successful software development is impossible without them.

When a system scales and manages large amounts of traffic, these factors become even more important.

If you believe your system will require more capacity in the future, particularly as it scales, you should utilize load balancers during your interviews.

Most often, they are situated between the servers of the application and the external traffic.
