Varnish is a web app accelerator, which has been gaining a lot in popularity in recent years, as it can increase the load speed of any website, sometimes even by one hundred percent, based on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to decrease the overall server load and to improve the browsing speed for the site visitors. Whenever a visitor opens a page on a certain site, the browser request is processed by the web server and the requested data is returned as a response. If Varnish is enabled, it caches the pages that the website visitor opens and if any of them is accessed for a second time, it is fetched by Varnish and not by the web server directly. The performance increase comes from the fact that the accelerator processes the browser requests substantially quicker than any web server, which leads to much faster browsing speeds for the website visitors. If any content is modified meanwhile, the cached webpages will also be ‘refreshed’ the next time someone tries to open them.

Varnish in Hosting

You can make use of Varnish’s full potential and boost the loading speed of your sites irrespective of the hosting package that you’ve picked and you can enable and set up the platform with a couple of mouse clicks from the easy-to-work-with GUI offered by our next-generation Hepsia hosting Control Panel. During the process, you’ll be able to select two separate things – how many websites will use the Varnish caching platform, in other words – the number of instances, and how much data will be cached, i.e. the amount of system memory. The latter is offered in increments of 32 MB and is not bound to the number of instances, so you can order more instances and less memory and the other way around. If you have lots of content on a given site and you get lots of website visitors, more system memory will give you better results. You may also consider using a dedicated IP address for the websites that will use Varnish. Hepsia will provide you with simple one-click buttons for stopping or rebooting any instance, for erasing the cache for each site and for checking exhaustive system logs.

Varnish in Semi-dedicated Hosting

The semi-dedicated hosting offered by us will permit you to employ Varnish once your brand new semi-dedicated account is active, as the content caching platform is offered by default. 64 MB of system memory will be allocated to Varnish the second your account is activated, so you can make use of this load distribution software as soon as your website has been published to the web. If you’re in need of more system memory, you can get 32 megabytes at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated machine immediately. You can also increase the number of the websites that use Varnish, or the so-called ‘instances’, which are not directly bound to the amount of system memory that you use, which goes to say that you’ll enjoy more freedom. The Varnish platform will considerably lower the load on the server generated by your websites, so your site visitors can enjoy fast-opening pages. You will be able to manage the Varnish caching platform without effort via your Control Panel using quick-access buttons. You’ll be able to start/disable any of the instances that you’ve got, to clear the cached data associated with any of your websites or to view system log files.

Varnish in VPS

We offer Varnish with all of the Hepsia-managed Linux VPS services, so if you buy a VPS with this hosting Control Panel, you’ll be able to take full advantage of the content caching platform at no extra cost. The Varnish platform can use different amounts of memory for caching purposes depending on the very Virtual Private Server package that you have selected during the VPS order process, but nevertheless, this amount will not be less than several hundred megabytes. This is quite enough to optimize the work of several different resource-requiring sites, so the faster website browsing speeds and the decreased load on your Virtual Private Server will be perceivable. The result may not be evident instantly, since Varnish will require some time to cache the website content that visitors request, but shortly after you enable it, you’ll observe its full potential. This caching platform will permit you to use a lower-end server and to pay less money to get the very same performance you’d get with a more powerful machine without Varnish.

Varnish in Dedicated Hosting

In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll obtain the Varnish platform at no additional cost and you’ll exert full control over it through an incredibly easy-to-work-with GUI – you’ll be able to start, to discontinue or to restart an instance, to browse an elaborate system log, to delete the cached data for any site and much, much more. The Varnish platform will have several GB of memory at its disposal, so even if you run large-sized websites with plenty of visitors, you’ll notice the tremendously faster web page loading times and the reduced load on your server. This will become a fact soon after you begin using the Varnish platform, as it will need a certain amount of time to cache the content that users access. You can make the most of the platform’s capability if the websites that are using it use also a dedicated IP address, but considering the fact that your dedicated server comes with several IP addresses by default, you won’t need to pay anything on top of the monthly charge for the server itself.
