To build the domain search service, Namecheap used a combination of technologies including Go, React, and Kubernetes. Go is a programming language that is designed to be efficient and highly concurrent, making it ideal for building large-scale web applications.
One of the key challenges that Namecheap faced when building the domain search service was processing the large number of requests that the system receives. To address this challenge, the company implemented a caching layer that stores frequently accessed data in memory. This allows the system to quickly retrieve data without having to perform expensive database queries.
