Varnish is a web application accelerator tool, which has been gaining a lot in popularity in recent years, because it can increase the load speed of any Internet site, at times even by one hundred percent, depending on the content itself. This tool is sometimes referred to as a caching HTTP reverse proxy as well and is used to lower the overall server load and to boost the browsing speed for the site visitors. Anytime a visitor accesses a page on a certain Internet site, the web browser request is processed by the web server and the requested data is sent as a response. If the Varnish accelerator is activated, it caches the pages that the visitor browses and if any of them is loaded once more, it is fetched by Varnish and not by the web server directly. The performance improvement comes from the fact that the accelerator handles the web requests significantly faster than any web server, which results in much faster browsing speeds for the site visitors. In case any content is changed in the meantime, the cached webpages will also be ‘refreshed’ the next time someone attempts to open them.

Varnish in Shared Hosting

Varnish comes as an optional upgrade with each and every Linux shared hosting plan and if you wish to use it, you can add it to your shared account through the Upgrades section in your Hepsia Control Panel. There’re two different features that can be upgraded – the number of instances and the memory. The first one refers to the number of the sites that you’d like to employ Varnish for and the second one, which comes in increments of 32 MB, shows the maximum amount of data that the platform can cache at any particular moment. The Hepsia Control Panel’s easy-to-use interface will enable you to deactivate or to restart any instance, to check elaborate system logs or to clear the platform’s cache with just a click. For optimum results, you can employ a dedicated IP for the websites that will use the caching platform. With Varnish, your Internet site will open tremendously faster, meaning more happy visitors and potential clients.

Varnish in Semi-dedicated Servers

Varnish is included as standard with all Linux semi-dedicated plans that we offer and you can use it for load distribution purposes. It is available in your Hepsia Control Panel. The data caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can employ it with any website that you host in the semi-dedicated account. In case you need more than that, you can increase the system memory quota. The memory itself is offered in increments of 32 MB in the Control Panel’s Upgrades section. The very same Upgrades section will permit you to create more instances as well, in case you’d like to use the Varnish platform with more Internet sites. The two things can be ordered independently – you can cache the content of one large-scale Internet site or use several Internet sites with the default memory quota. You can take full advantage of Varnish if you have a dedicated IP and you can order one with your semi-dedicated server package as well. The Hepsia Control Panel will give you total control over the caching platform and, with no more than one single mouse click, you’ll be able to clear the cached data, to view a system log file or to restart an instance.

Varnish in VPS Servers

You can use Varnish with all our VPS server plans at no additional cost, as the data caching platform is pre-installed and is available by default. The one and only condition is that the VPS server must be ordered with the Hepsia hosting Control Panel, through which you will be able to activate Varnish for any of your websites with just a few mouse clicks. Each VPS plan features a different amount of system memory for caching purposes, but you will get no less than several hundred MB, which is quite enough even for several resource-absorbing Internet sites. Soon after you set up Varnish, it’ll start caching the content that your website visitors open, so you will notice the much better page loading speeds and the lowered load on the virtual server in no time. The caching platform will allow you to use a less expensive VPS server, as you will not require that much power to warrant the correct operation of your Internet sites even if you run large-size Internet sites with numerous visitors. Optimum results are achieved if the Internet sites that use the Varnish caching platform use also a dedicated IP address.

Varnish in Dedicated Servers

All Linux dedicated servers which are ordered with the in-house built Hepsia website hosting Control Panel include Varnish, which is among the pre-installed platforms that you’ll get with the dedicated server. The Varnish content caching platform can be configured and administered with no effort through the Hepsia Control Panel’s simple-to-work-with graphical interface and, with no more than one click, you can check an exhaustive log, create or restart an instance, clear the cache for any site and much more. Soon after you activate Varnish for a specific domain or subdomain, it will start caching the pages requested by the site visitors and as soon as it has cached enough content, you’ll witness a substantially better website performance in addition to a lowered load on the server. With Varnish-dedicated system memory starting at three gigabytes, you will be able to use the platform for load balancing purposes even if you run a vast number of Internet sites on your server.
