What are large scale web applications?

Hence, a large-scale web app is one that can handle high volumes of data and traffic and can adapt to drastic load changes without affecting the quality of operations. This can be evaluated on: Data – it can handle large volumes of different data types (e.g., it can handle customers and track their behavior).

What is considered a large scale application?

But a large scale web application has characteristics such as these: performance, being able to handle a large number (millions) of users/request or a large number (thousands) of transactions per second. Both have challenges depending on the type of app (CPU bound, IO bound or both).

How to increase the response time of a large scale web application?

One of the most common approaches to increase the response time of a large scale web application is to separate the permanent storage tier into a separate node. Now you have some resources freed for the rest of the application to run faster.
