Varnish is a website accelerator tool, which has been gaining a lot in popularity lately, as it can increase the load speed of any Internet site, sometimes even by 100 percent, based on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to lower the overall server load and to enhance the browsing speed for the site visitors. Each time a visitor loads a page on a certain website, the web browser request is handled by the web server and the requested content is returned as a response. If Varnish is enabled, it caches the web pages that the site visitor opens and in case any of them is accessed again, it’s fetched by Varnish and not by the web server directly. The improvement in the performance is due to the fact that the accelerator handles the web requests significantly quicker than any web server, which leads to much faster browsing speeds for the website visitors. If any content is updated meanwhile, the cached webpages will also be ‘refreshed’ the next time somebody attempts to access them.

Varnish in Cloud Web Hosting

Varnish is offered as an optional upgrade with each of our cloud web hosting. You can add it to your website hosting account from the Hepsia Control Panel, which is offered with all shared web hosting packages and you’ll get a really intuitive graphical interface, which will grant you full control over the caching platform. Using one-click fast-access controls, you can restart or terminate any of the instances, i.e. Varnish will no longer be enabled for a certain Internet site. You can also view a comprehensive log or delete the cache associated with any of the Internet sites. When you add Varnish to your shared hosting package, you will be able to select the total amount of system memory that will be available to you for content caching purposes and the number of the sites that will use Varnish. You can always add more memory in increments of 32 MB and, for optimal performance, you can allocate a dedicated IP to the sites that will use Varnish. This will enable you to take full advantage of your websites and to have a lot of happy users.

Varnish in Semi-dedicated Servers

Varnish is included in the basic set of services that you’ll get when you decide to host your Internet sites in a semi-dedicated server account. You can configure it for any of your websites via our avant-garde Hepsia hosting Control Panel. The default amount of memory that the Varnish caching platform can use to cache data is 64 MB, but in case you decide that you want more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this platform at the same time. As these two features are not linked to each other, you can use several Internet sites with the default amount of memory or you can get more memory in increments of 32 MB and use all of it for one single website. The Varnish platform works best if you assign a dedicated IP to the Internet sites that utilize its power. Hepsia will offer you an easy means of rebooting any instance. Furthermore, you will be able to clear the cached files with only a click.

Varnish in VPS Servers

You can take advantage of Varnish with all our VPS server packages at no additional fee, as the caching platform is pre-installed and is offered by default. The only precondition is that the virtual machine must be ordered with the Hepsia hosting Control Panel, via which you’ll be able to activate Varnish for any of your Internet sites with just a couple of mouse clicks. Each Virtual Private Server package includes a different amount of memory for caching purposes, but you’ll have no less than several hundred megabytes, which is quite enough even for multiple large-scale Internet sites. Soon after you set up Varnish, it’ll start caching the content that your website visitors open, so you will notice the significantly faster site load times and the decreased load on the server very soon. The platform will permit you to use a less pricey virtual server, as you won’t need that many resources to ensure the uninterrupted operation of your Internet sites even if you own traffic-consuming sites with lots of visitors. Optimal 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 that are ordered with the in-house built Hepsia website hosting Control Panel feature Varnish, which is one of the pre-installed software platforms that you will get with the server. The Varnish content caching platform can be enabled and managed without efforts via the Hepsia Control Panel’s user-friendly graphical interface and, with no more than one click of the mouse, you can view an in-depth system log, add or restart an instance, delete the cache associated with any website and much, much more. Shortly after you activate the Varnish platform for a given domain or subdomain, it will start caching the pages loaded by your website visitors and as soon as it has cached enough web content, you will witness a significantly faster website performance in addition to a reduced load on the dedicated machine. With Varnish-dedicated memory starting at 3 gigabytes, you will be able to use the platform for load distribution purposes even if you host a vast number of sites on the dedicated machine.
