While Scala has been popular, another language which is based on Java uses JVM and is compatible with Java has gained attention in recent years – Kotlin.

As your user base grows, your need for computing power also goes up. When you started with only a few users, you probably had only one web server. However, with the increased user base, you will need additional servers. As you put additional servers, you need to have some algorithm to decide which server should get the new traffic. Load Balancer helps you with this need.
