How to Install Varnish Cache on Windows

How to Install Varnish Cache on Windows

Caching is not just a process of storing data in a temporary storage unit but also one of the pillars of web performance optimization. It’s a powerful technique to make your website load faster. The website can’t be called optimized without using a caching system.

In Magento 2, cleaning and flushing cache is essential after modifying configuration files, to apply the required changes. It collects configuration from all modules, merges it, and saves the merged result to the cache. This cache also contains store-specific settings stored in the file system and database.

By default, you can configure Magento 2 ‘Caching Application’ from Stores > Configuration > Advanced > System > Full Page Cache . You can see ‘Varnish Cache’ option with the recommended label.

You have to install varnish cache on windows to use its functionalities and configure it as this post shows you how to do it.
Let me first introduce “varnish” to you and how it’s different from the Magento default cache.

Varnish cache is a web application accelerator which stores files or fragments of files in memory to reduce the response time and network bandwidth consumption on future equivalent requests. 

The varnish is a much quicker option and will give you the flexibility to cache most of your content, including HTML documents!

“Built-in “Full Page Cache” is enough for better performance”, and it’s the common misbelief while using Magento 2!

Individually, I recommend you to use built-in cache in development mode however when your store is in production mode, I strongly recommend using Varnish Cache for the optimal performance.
