When responding to a technical question, you should keep your answer brief and to the point. Embellishing your answer or adding additional details not relevant to the original question may make it seem like you're making up the answer or not answering truthfully. Interviewers prefer direct and simple answers to their questions. They will ask a follow-up question if they need more information or want to explore the topic in more detail.

"Scalability is the ability of a website to handle increasing demand or views by adding additional resources. This can be done in two ways. The first is to scale up, which involves adding more resources to existing website applications, such as more memory, storage, or network connections. The second is scaling out, which is replicating the existing resources to handle the increasing demand. The cost of adding resources may vary, depending on the type and number of resources required to handle the load. Web architects need to take this into account in their initial design."
