Varnish is a web accelerator platform, which caches data for quicker access. It’s sometimes referred to as a caching HTTP reverse proxy as well and it works between a web server and its users. When a visitor loads a certain webpage, its content is requested by the browser, and then the web server processes this browser request and delivers the needed data. If Varnish is enabled for a website, it will cache the pages on the first request and in case the visitor visits a cached page once again, the data will be delivered by the caching platform instead of the server. The improved loading speed is an end result of the much faster response time that Varnish offers compared to any web server software. At the same time, this doesn’t mean that the visitors will continue being served the very same content over and over again, because any modification on any of the web pages is reflected in the content that Varnish keeps in its system memory.

Varnish in Shared Web Hosting

In case you host your Internet sites in a shared web hosting account with our company, you’ll be able to add Varnish with several mouse clicks via your Control Panel. The data caching platform is offered as an upgrade with all our hosting plans and you can choose the number of the sites that will use it and the total storage space that will be available for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they aren’t linked directly to each other, so you can decide whether you need lots of memory for one large website or less memory for several smaller ones. You can take advantage of the full potential of the Varnish platform in case the websites use a dedicated IP address. Using the hosting Control Panel, you can effortlessly start/restart/delete an instance, clear the cached content independently for each website which employs the Varnish platform or view a detailed log.

Varnish in Semi-dedicated Servers

Varnish is a feature, which comes as standard with all Linux semi-dedicated hosting plans that we are offering and you can use it for load distribution purposes. It’s available in your Hepsia hosting Control Panel. The Varnish content caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can employ it with any Internet site that you host in your semi-dedicated server account. If you need more than that, you can increase the system memory allocation. The memory itself is offered in increments of 32 MB in the Upgrades section of the Control Panel. The very same Upgrades section will enable you to create more instances too, if you’d like to use Varnish with multiple sites. The two things can be ordered separately – you can cache the content of a single resource-heavy site or use several websites with the default memory quota. You can take full advantage of the Varnish caching platform if you use a dedicated IP and you can get one with your semi-dedicated server package as well. The Hepsia Control Panel will grant you complete control over the platform and, with no more than one click of the mouse, you’ll be able to delete the cached files, to see a log file or to restart an instance.

Varnish in VPS Servers

The Varnish platform is included by default with all VPS hosting plans offered by us as long as the machine is ordered with the Hepsia Control Panel, so you can improve the performance of your websites with only a few clicks of the mouse. The more powerful the plan, the more memory Varnish will have at its disposal, but even with a lower-end plan, the platform will be able to utilize several hundred MB, so even if you have several Internet sites, you’ll notice a noticeable reduction in the overall server load and a significantly better page loading speed. The Varnish caching platform will need to work for a little while as the visitors navigate the website and once the site content has been cached, you’ll see the results. One of the advantages of using Varnish is that a lower-end and less expensive Virtual Private Server package will do the exact same job as a more high-priced one without the caching platform, so not only will your sites work substantially better, but you’ll also spare some money.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you will get the Varnish caching platform at no extra fee and you will have full control over it through an incredibly time and effort saving GUI – you will be able to start, to deactivate or to reboot an instance, to check an exhaustive log, to delete the cached content associated with any Internet site and much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you own large-size websites with an enormous number of visitors, you’ll notice the much faster site load speeds and the less load on the dedicated server. This will become a fact soon after you start using Varnish, as it will need some time to cache the content that people access. You can get the most out of the platform’s capabilities in case the Internet sites that are using it also use a dedicated IP address, but owing to the fact that your dedicated server includes a few IP addresses by default, you will not have to pay anything on top of the monthly fee for the machine itself.
