Varnish is a web app accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the speed of any site, at times even by 100%, depending on the content. This tool is occasionally called a caching HTTP reverse proxy as well and is used to decrease the overall load on the physical server and to boost the browsing speed for the website visitors. Each time a visitor loads a page on a particular Internet site, the web browser request is handled by the web server and the requested info is delivered as a reply. If Varnish is activated, it caches the web pages that the site visitor browses and if any of them is accessed once again, it’s fetched by Varnish and not by the server directly. The improvement in the overall performance comes from the fact that the accelerator handles the browser requests considerably faster than any web server, which leads to much faster browsing speeds for the visitors. If any content is changed meanwhile, the cached pages will also be updated the next time somebody tries to access them.

Varnish in Website Hosting

In case you host your Internet sites in a website hosting account with us, you’ll be able to add Varnish with several clicks through your hosting Control Panel. The caching platform is offered as an optional upgrade with all our packages and you can choose how many sites will use it and the maximum amount of system memory that will be used for the cached data. The two upgradeable features in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they aren’t linked directly to each other, so you can choose whether you need plenty of memory for one large-scale website or less memory for several smaller ones. You can unlock the full potential of the Varnish platform in case the sites use a dedicated IP. Using the hosting Control Panel, you can swiftly start/reboot/cancel an instance, clear the cached contents independently for each site that employs the Varnish platform or view an in-depth log.

Varnish in Semi-dedicated Hosting

Varnish is a feature, which is offered as standard with all Linux semi-dedicated hosting packages that we offer and you can use it for workload balancing purposes. It is available in your Hepsia Control Panel. The Varnish content caching platform comes with 64 MB of system memory for cached content storing purposes and you can employ it with any website that you host in the account. In case you are in need of more than that, you can increase the memory quota. The memory itself is available in increments of 32 megabytes in the Control Panel’s Upgrades section. The very same section will enable you to create more instances as well, if you would like to use the Varnish caching platform with more sites. The two upgrades can be ordered separately – you can cache the content of one traffic-consuming Internet site or use a number of sites with the default memory. You can take full advantage of Varnish if you have a dedicated IP address and you can get one with your semi-dedicated server package as well. The Hepsia Control Panel will give you full control over the platform and, with no more than one single click, you’ll be able to clear the cache, to see a log or to restart an instance.

Varnish in VPS Hosting

You can use the load balancing capabilities of Varnish with any of our Linux VPS hosting packages if you choose Hepsia as your Control Panel. The Varnish caching platform is available by default and the amount of system memory that it’ll be able to utilize to cache the content of your websites depends on the particular package that you’ve selected, but even with the less powerful packages, you will have at least several hundred megabytes of memory at your disposal exclusively for data caching purposes. This amount is sufficient enough to enhance the overall performance of numerous websites. It’ll take a little time for you to distinguish the effects, since Varnish caches the content that site visitors open, but soon thereafter you will notice the substantially reduced load on your virtual server and the enhanced Internet site load speed. Varnish will allow you to use a less powerful plan for websites that would typically require a more costly web hosting service.

Varnish in Dedicated Web Hosting

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll obtain the Varnish data caching platform at no additional charge and you will have complete control over it through an amazingly user-friendly GUI – you’ll be able to start, to discontinue or to reboot an instance, to browse a comprehensive log, to clear the cached files associated with any Internet site and much, much more. The Varnish caching platform will have several GB of memory at its disposal, so even if you host large-scale websites with numerous visitors, you will notice the much faster website load speeds and the reduced server load. This will happen shortly after you begin using the Varnish platform, since it will need some time to cache the site content that users request. You can take full advantage of the platform’s potential if the Internet sites that are using it use also a dedicated IP address, but due to the fact that your dedicated server comes with a few IPs by default, you will not have to pay anything on top of your monthly fee for the server itself.
