Varnish is a web app accelerator tool, which has been gaining a lot of popularity in recent years, as it can increase the speed of any site, at times even by one hundred percent, depending on the content. This tool is sometimes referred to as a caching HTTP reverse proxy as well and is used to lower the overall load on the server and to accelerate the browsing speed for the site visitors. Each time a visitor loads a page on a specific Internet site, the web browser request is handled by the web server and the requested information is served as a response. If the Varnish accelerator is activated, it caches the pages that the visitor browses and if any of them is opened again, it is fetched by Varnish and not by the server directly. The increase in the overall performance is due to the fact that the accelerator handles the browser requests tremendously quicker than any web server, which results in much faster browsing speeds for the website visitors. If any data is edited meanwhile, the cached web pages will also be updated the next time somebody tries to open them.

Varnish in Shared Hosting

Varnish comes as an optional upgrade with each of our shared hosting. You can add it to your hosting account from the Hepsia Control Panel, which is offered with all shared hosting plans and you’ll get a pretty user-friendly GUI, which will grant you complete control over the content caching system. Using 1-click fast-access controls, you can reboot or remove any of the instances, i.e. Varnish will no longer be enabled for a certain Internet site. You can also see a detailed log or clear the cache associated with any of the websites. When you add Varnish to your hosting package, you’ll be able to choose the total amount of system memory that will be available to you for caching purposes and how many websites will use Varnish. You can always get more memory in increments of 32 megabytes and, for optimal performance, you can assign a dedicated IP address to the websites that will use Varnish. This will allow you to take full advantage of your Internet sites and to have lots of pleased site users.

Varnish in Semi-dedicated Servers

The Varnish data caching platform is an essential part of the standard service set that you’ll get when you choose to host your websites under a semi-dedicated server account. You can set it up for any of your sites through our innovative Hepsia Control Panel. The default memory that the Varnish platform can use to cache data is 64 MB, but in case you decide that you need more, you can upgrade this amount of memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the websites that can use this caching platform simultaneously. As these two features aren’t linked to each other, you can use a couple of Internet sites with the default memory or you can get more memory in increments of 32 megabytes and use all of it for one single web site. The Varnish platform performs best when you set a dedicated IP for the Internet sites that utilize its power. The Hepsia Control Panel will give you an easy way of rebooting any instance. What’s more, you will be able to clear the cached data with just a click.

Varnish in VPS Servers

You can use Varnish with each of our VPS server plans at no extra fee, as the platform is pre-installed and is offered by default. The one and only prerequisite is that the VPS must be ordered with the Hepsia hosting Control Panel, through which you’ll be able to activate Varnish for any of your Internet sites with just a couple of clicks of the mouse. Each Virtual Private Server plan includes a different amount of memory for caching purposes, but you will get minimum several hundred MB, which is sufficient even for several resource-consuming sites. Shortly after you activate Varnish, it’ll begin caching the content that your visitors browse, so you’ll notice the substantially faster site load times and the decreased load on the server very soon. The caching platform will permit you to use a less expensive Virtual Private Server, since you will not require that many resources to ensure the proper operation of your websites even if you’ve got large websites with numerous visitors. Maximum results are achieved if the websites which use the Varnish caching platform use also a dedicated IP address.

Varnish in Dedicated Servers

All dedicated servers that are ordered with the custom-developed Hepsia web hosting Control Panel come with Varnish, which is one of the pre-installed platforms that you will get with the dedicated machine. The Varnish content caching platform can be enabled and administered without effort through Hepsia’s easy-to-use interface and, with no more than one click of the mouse, you can view a comprehensive system log, create or restart an instance, clear the cache associated with any website and much, much more. Shortly after you set up Varnish for a given domain or sub-domain, it will start caching the web pages loaded by the visitors and as soon as it has cached enough content, you will observe a tremendously faster website performance in addition to a lowered load on the server. With Varnish-dedicated system memory starting at three gigabytes, you’ll be able to use the platform for load distribution purposes even if you run numerous websites on the dedicated server.
