Millions of people worldwide stream more than two billion hours worth of video from Netflix each month. Another example is Facebook, which roughly had 2.85 billion active users in the first quarter of 2021.
Talking about the e-commerce giant, Amazon receives more than 66 thousand orders per hour, and 18.5 orders per second. Whoooo!
So, how do these organizations manage such a colossal flow of consumers on their websites and apps? How do they enable millions of users to access their accounts, use available functions and perform desired actions without any hassle or downtime?
Well, that is scalability in action for you. Given this dynamic, Facebook, Amazon, Netflix are all wonderful examples of scalable applications.
Scalable web applications can easily cope up with the rising numbers of users. From the application perspective, scalability refers to the capacity to handle the growth. User behavior suggests the minimal amount of waiting that people are willing to dedicate for a process to form, image to load or an application to open.
In the chaotic world of apps, a scalable web application is the king. With rapidly evolving user expectations and market needs, web apps must have the ability to handle a growing number of users or even sudden spikes in demand from a big pool of app/website users.
