Applications of Caching
Facebook, Instagram, Amazon, Flipkart….these applications are the favorite applications for a lot of people and most probably these are the most frequently visited websites on your list.
Have you ever noticed that these websites take less time to load than brand-new websites? And have you noticed ever that on a slow internet connection when you browse a website, texts are loaded before any high-quality image? Why does this happen?
The answer is Caching.
- If you check your Instagram page on a slow internet connection you will notice that the images keep loading but the text is displayed. For any kind of business, these things matter a lot.
- A better customer/user experience is the most important thing and you may lose a lot of customers due to the poor user experience with your website.
- A user immediately switches to another website if they find that the current website is taking more time to load or display the results.
You can take the example of watching your favorite series on any video streaming application. How would you feel if the video keeps buffering all the time? Chances are higher that you won’t stick to that service and you discontinue the subscription. All the above problems can be solved by improving retention and engagement on your website and by delivering the best user experience. And one of the best solutions is Caching.
