Varnish is a content caching platform, which is sometimes referred to as an HTTP reverse proxy. It’s a web accelerator tool that can accelerate the loading speed of a site by up to 1000%, depending on the content itself. Each time a visitor accesses any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor loads it again. In this way, the browser request from the visitor is not processed by the server and the web page will open significantly faster, since the Varnish caching platform can deliver information many times faster than any server software. The end result will be a significantly faster loading site, which means an immensely improved website browsing experience. When any of the cached pages is updated on the actual website, the data that Varnish keeps in its memory is ‘refreshed’ too, so the website visitors will never see old data.
Varnish in Cloud Hosting
Varnish is offered as an optional upgrade with all our Linux cloud service
. You can add it to your website hosting account from the Hepsia hosting Control Panel, which is offered with all shared packages and you will get a quite user-friendly GUI, which will give you complete control over the content caching system. Using one-click quick-access controls, you can reboot or shut down any of the instances, i.e. Varnish will no longer be activated for a given website. You can also see an exhaustive log or erase the cache for any of the websites. When you add Varnish to your hosting package, you will be able to choose the total amount of memory that will be available to you for caching purposes and the number of the sites that will use Varnish. You can always get more memory in increments of 32 megabytes and, for optimum performance, you can allocate a dedicated IP address to the sites that will use Varnish. This will enable you to take full advantage of your Internet sites and to have a lot of happy users.
Varnish in Semi-dedicated Servers
Varnish is a feature, which comes as standard with all semi-dedicated servers
that we’re offering and you can use it for workload balancing purposes. It’s available in your Hepsia Control Panel. The Varnish platform comes with 64 megabytes of system memory for cached content storing purposes and you can employ it with any site that you host in the account. In case you are in need of more than that, you can increase the system memory quota. The memory itself is available in increments of 32 megabytes through the Upgrades section of the Control Panel. The same Upgrades section will permit you to add more instances too, in case you wish to use the Varnish platform with more sites. The two upgrades can be added separately – you can cache the content of one regularly visited Internet site or run several Internet sites with the default memory quota. You can get the most out of Varnish 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 total control over the caching platform and, with no more than one single mouse click, you’ll be able to clear the cached content, to see a log file or to restart an instance.
Varnish in VPS Servers
You can use Varnish with each of our VPS server
plans at no additional charge, as the content caching platform is pre-installed and is offered by default. The one and only prerequisite is that the Virtual Private Server must come with the Hepsia Control Panel, via which you will be able to set up Varnish for any of your Internet sites with only a few clicks of the mouse. Each plan features a different amount of system memory for content caching purposes, but you will have at least several hundred megabytes, which is sufficient enough even for several resource-demanding websites. Shortly after you enable the Varnish platform, it will begin caching the content that your visitors open, so you’ll notice the much better web page loading times and the decreased server load in no time. The platform will allow you to use a less expensive virtual machine, since you will not need that much power to warrant the proper operation of your websites even if you manage larger websites with a lot of visitors. Optimal results are accomplished if the Internet sites which use Varnish use also a dedicated IP.
Varnish in Dedicated Servers
When you need the most powerful web hosting solution and you purchase one of the Linux dedicated servers
that we are offering, you will be able to use the Varnish platform to optimize the work of your websites at no additional charge on the condition that the dedicated server is ordered with our advanced Hepsia hosting Control Panel. Its easy-to-work-with graphical interface will permit you to keep an eye on platform processes, to delete the cached data or to restart any instance with one single click. The smallest amount of system memory that Varnish can employ to cache website content is 3 GB, which is quite enough for a vast selection of traffic-consuming Internet sites, so your dedicated server will be able to deal with a colossal load while your Internet site visitors are enjoying a smooth web browsing experience. As your dedicated machine will come with several dedicated IP addresses, you will be able to make use of Varnish’s full capacity.
