Varnish is a web application accelerator platform, which caches content for the sake of quicker access. It’s sometimes referred to as a caching HTTP reverse proxy too and it works between a web server and a web browser. When a website visitor loads a certain page, its content is requested by the Internet browser, and then the web server processes this browser request and returns the needed content. If Varnish is enabled for a certain website, it will cache the pages at the very first request and in case the visitor opens a cached page once more, the info will be delivered by the caching platform instead of the server. The improved load speed is an end result of the considerably faster response speed that Varnish offers compared with any server software. At the same time, this does not mean that the users will continue being served the very same content again and again, as any update on any of the pages is reflected in the content that the Varnish platform caches in its system memory.
Varnish in Cloud Hosting
In case you host your websites in a cloud hosting
account with us, you’ll be able to activate Varnish with several clicks through your hosting Control Panel. The data caching platform is available as an optional upgrade with all our plans and you can choose how many websites will use it and the total amount of system memory that will be available for the cached data. The two features that can be upgraded in the Upgrades section of the Control Panel are the number of instances and the amount of system memory and they are not directly linked to each other, so you can decide whether you want plenty of memory for a single large-sized website or less memory for multiple smaller ones. You can take advantage of the full potential of Varnish if the sites use a dedicated IP. Using the Control Panel, you can quickly start/reboot/cancel an instance, delete the cached content individually for each website that employs Varnish or check an elaborate system log.
Varnish in VPS Servers
The Varnish caching platform is included by default with all VPS servers
that we’re offering given that the VPS is ordered with the Hepsia hosting Control Panel, so you can improve the overall performance of your sites with just a couple of mouse clicks. The more powerful the package, the more memory Varnish will have at its disposal, but even with a less powerful plan, the platform will be able to utilize several hundred MB, so even if you have several different Internet sites, you’ll notice a considerable reduction in the server load and a considerably faster site loading speed. The Varnish platform will need to work for a while while the users browse the site and once the website content has been cached, you’ll observe the result. One of the pluses of employing Varnish is that a lower-end and less costly plan will accomplish the exact same job as a more high-priced one without the platform, so not only will your Internet sites work considerably better, but you will also save a certain amount of money.
