Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, because it can increase the speed of any site, sometimes even by 100 percent, based on the content itself. This tool is sometimes called a caching HTTP reverse proxy as well and is used to reduce the overall server load and to increase the access speed for the website visitors. Each time a visitor opens a page on a certain website, the browser request is taken care of by the web server and the requested info is served as a reply. If Varnish is activated, it caches the web pages that the website visitor opens and if any of them is accessed for a second time, it’s fetched by Varnish and not by the web server directly. The boost in the overall performance comes from the fact that the accelerator processes the browser requests significantly faster than any web server, which results in much faster browsing speeds for the users. If any data is modified meanwhile, the cached pages will also be ‘refreshed’ the next time somebody tries to access them.
Varnish in Shared Hosting
You can use Varnish’s potential and enhance the load speed of your sites irrespective of the shared hosting package that you’ve chosen and you can add and configure the platform with a few clicks of the mouse via the simple-to-work-with GUI offered by our innovative Hepsia Control Panel. In the meantime, you will be able to choose two different things – how many websites will employ the Varnish platform, in other words – the number of instances, and how much information will be cached, i.e. the amount of memory. The latter is available in increments of 32 megabytes and is not linked to the number of instances, so you can add more instances with less memory and vice versa. If you have a lot of content on a specific website and you attract numerous visitors, more memory will guarantee you a better result. You may also consider employing a dedicated IP for the websites that will use the Varnish caching platform. Hepsia will offer you easy 1-click controls for disabling or restarting any instance, for erasing the cache for any site and for viewing in-depth system logs.
Varnish in Semi-dedicated Servers
The semi-dedicated hosting service offered by our company will permit you to employ Varnish once your brand-new account is active, as the caching platform is available by default. 64 megabytes of system memory will be assigned to Varnish the moment your account is activated, so you can use this load balancing software as soon as your site has been published to the web. In case you are in need of more memory, you can add 32 MB at a time from the Hepsia Control Panel’s Upgrades section and it will be allocated to your semi-dedicated server immediately. You can also increase the number of the websites that use Varnish, or the so-called ‘instances’, which are not directly tied to the amount of memory that you use, which means that you will have more flexibility. The platform will enormously reduce the server load caused by your sites, so your website visitors can enjoy fast-loading pages. You will be able to manage the Varnish platform without effort via your Control Panel using fast-access buttons. You will be able to start/terminate any of the instances that you’ve got, to clear the cached data associated with any of your websites or to check system log files.
Varnish in VPS Servers
You can take full advantage of the workload balancing potential of Varnish with all our Linux VPS servers in case you pick Hepsia as your web hosting Control Panel. The platform is available by default and the amount of memory that it’ll be able to use to cache your site content depends upon the specific VPS plan that you’ve selected, but even with the less powerful plans, you will have at least several hundred megabytes of memory at your disposal only for content caching purposes. This amount is sufficient to improve the overall performance of numerous websites. It will take some time for you to distinguish the results, as the Varnish platform caches the content that website visitors access, but after that you will notice the substantially reduced load on the server and the accelerated Internet site browsing speed. The Varnish caching platform will allow you to make use of a less powerful plan for Internet sites that would usually require a more high-priced web hosting solution.
Varnish in Dedicated Servers
All dedicated servers which are ordered with the in-house developed Hepsia web hosting Control Panel come with Varnish, which is one of the pre-installed platforms that you will get with the dedicated server. The Varnish content caching platform can be enabled and managed with ease via the Hepsia Control Panel’s simple-to-navigate graphical interface and, with no more than one click of the mouse, you can see an in-depth system log, create or restart an instance, delete the cached data for any site and much, much more. Shortly after you set up Varnish for a certain domain or sub-domain, it will start caching the webpages opened by your website visitors and as soon as it has cached enough web content, you’ll perceive a tremendously faster website performance plus a decreased load on the dedicated machine. With Varnish-dedicated virtual memory starting at 3 GB, you will be able to use the platform for load balancing purposes even if you host a vast number of sites on your machine.
