A cache is an essential component of a web server. With applications like Magento, cache plays an essential role in application performance because it drastically reduces the load on the application and speeds up page response. As a result, the user experience improves significantly. 

When it comes to Magento 2, Varnish is a popular choice. Magento 2 Varnish is a proven combination and increases site performance significantly. With previous versions of Magento, you need to install extensions such as “Phoenix Page Cache” or “Turpentine Varnish Cache” for integrating Varnish with Magento. With Magento 2, Varnish is integrated by default and requires minor configuration changes to make it work with your store.

What is Varnish Cache & How Does Magento Varnish Work?

Varnish cache helps boost up the speed of web applications. Technically, the proper term for Vanish is an HTTP accelerator, designed to accelerate content-heavy dynamic pages in order to improve the overall performance of the Magento 2 stores.

Basically, Magento Varnish builds fragments files that are stored in memory. This helps Varnish eliminate the time and network bandwidth consumption for upcoming requests.

While processing requests, HTTP manages all calls for CSS, HTML, JavaScript, and images. Varnish works to proxy these requests for the web server.

As the web server responds to these requests, Varnish stores the cacheable assets, and any subsequent user request is entertained by Varnish. As a result, the web server does not have to process the same requests over and over.

Note: Assets cached by Varnish can expire after a configurable interval and may be replaced by newer versions. You can also clear the cache manually by accessing the Magento Admin or by running the Magento cache: clean command via SSH.

Why Varnish Cache is Essential for Magento Stores

With Varnish integrated, Magento does not have to dedicate time and resources to serving duplicate requests. As a result, the user experience improves significantly because from the user perspective, the requests are being processed much faster and the pages load much faster in their browsers.
