Varnish is a web app accelerator, which has been gaining a lot of popularity in recent years, because it can increase the load speed of any Internet site, at times even by 100 percent, depending on the content itself. This tool is sometimes referred to as an HTTP reverse proxy as well and is used to decrease the overall load on the physical machine and to accelerate the access speed for the site visitors. Every time a visitor loads a page on a particular website, the web browser request is handled by the web server and the requested content is served as a response. If Varnish is activated, it caches the web pages that the site visitor opens and if any of them is loaded once again, it is fetched by Varnish and not by the server directly. The performance improvement is due to the fact that the accelerator processes the web requests considerably quicker than any web server, which results in much faster browsing speeds for the website visitors. If any data is updated meanwhile, the cached webpages will also be updated the next time someone attempts to open them.

Varnish in Shared Web Hosting

If you host your sites in a shared web hosting account with us, you will be able to activate Varnish with several mouse clicks via your hosting Control Panel. The data caching platform is offered as an optional upgrade with all our shared web hosting plans and you can select how many websites will use it and the total storage space that will be available for the cached content. The two upgradeable features in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they are not directly linked to each other, so you can decide if you need lots of memory for one single large-sized website or less memory for multiple smaller ones. You can unleash the full potential of the Varnish platform if the sites use a dedicated IP. With the hosting Control Panel, you can quickly start/reboot/shut down an instance, clear the cached content individually for each website which uses Varnish or see an exhaustive log.

Varnish in Semi-dedicated Hosting

Varnish is a feature, which is offered by default with all semi-dedicated hosting that we offer and you can use it for load balancing purposes. It’s available in your Hepsia hosting Control Panel. The Varnish content caching platform comes with 64 megabytes of system memory for cached data storing purposes and you can employ it with any site that you host in your account. In case you need more, you can increase the memory quota. The memory itself is offered in increments of 32 MB through the Upgrades section of the Control Panel. The exact same Upgrades section will permit you to activate more instances too, in case you’d like to use Varnish with more websites. The two upgrades can be added separately – you can cache the content of a single regularly visited site or run a number of websites with the default memory. You can get the most out of Varnish if you’ve got a dedicated IP and you can get one with your semi-dedicated server plan as well. Hepsia will grant you full control over the caching platform and, with no more than one single click, you’ll be able to clear the cached data, to check a system log or to reboot an instance.

Varnish in VPS Web Hosting

We offer Varnish with all Hepsia-managed Linux VPS web hosting, so if you buy a VPS with this web hosting Control Panel, you will be able to make use of the caching platform at no extra cost. Varnish can use different amounts of memory for data caching purposes based on the particular setup that you’ve selected during the subscription process, but nevertheless, this amount won’t be less than several hundred megabytes. This is more than enough to enhance the work of several resource-absorbing websites, so the faster website load speeds and the reduced load on the server will be perceivable. The effect may not be distinguishable instantly, as Varnish will need a certain amount of time to cache the content that visitors access, but soon after you activate it, you will feel its full capacity. This caching platform will permit you to use a less powerful VPS server and to pay less cash to get the exact same performance you would get with a higher-end virtual machine without Varnish.

Varnish in Dedicated Servers Hosting

If you order a dedicated server with the Hepsia Control Panel, you will get the Varnish platform at no extra cost and you’ll exert total control over it through an exceptionally simple-to-work-with graphical interface – you’ll be able to start, to delete or to restart an instance, to view a comprehensive system log, to clear the cached content for any site and much, much more. The Varnish caching platform will have several GB of virtual memory at its disposal, so even if you have busy sites with lots of visitors, you will notice the considerably faster website loading times and the less server load. This will become a fact shortly after you start using Varnish, since it will require some time to cache the web pages that users access. You can get the most out of the platform’s capabilities in case the Internet sites that are using it use also a dedicated IP address, but owing to the fact that your dedicated server comes with a couple of IP addresses by default, you will not need to pay anything on top of your monthly fee for the machine itself.
