What is Varnish Cache? — Explained

I’ve been a blogger for quite some time now. Around a year and a half ago, a friend and I started discussing about creating our own website. After some deliberation, we settled on a WordPress powered website. But the choice of hosting was still not clear.

Being in the web domain & hosting industry, I suggested we opt for varnish cache enabled hosting service so that the website’s growth in future can be handled easily without constant upgradation. If you too are clueless, like she was about what Varnish Cache is, this article will help you understand the wonder called Varnish Cache.

Let us begin by understanding, what is varnish cache.

Varnish Cache is a robust web accelerator that allows, content-rich dynamic websites to endure high traffic. It enables web pages to load faster, by as much as 1000%. Thus, the average waiting time for a page to load is drastically reduced.

Usually, whenever a user requests data from a website, the data is received by the user by the common request-response practice. Here the browser of the user and the web server of the hosted website converse. Once the server receives the browser’s request, it decodes the request, understands, collects and assembles the required resources and, finally sends the data back to the browser. It follows this procedure for every single request.

If you’re an e-commerce website or a website dealing with heavy traffic, chances are your website will become slow as the passing and retrieval process takes times. This is where Varnish Cache comes into the picture.
