Varnish is a web application accelerator platform, which caches data for the sake of faster access. It’s occasionally called a caching HTTP reverse proxy as well and it works between a web server and an Internet browser. When a visitor accesses a specific web page, the content is requested by the browser, and then the web server processes this browser request and sends back the requested information. If Varnish is enabled for a particular website, it will cache its pages at the first visit and if the visitor visits a cached page once again, the content will be delivered by the caching platform and not by the web server. The accelerated loading speed is an end result of the much faster response time that Varnish offers as compared to any web server software. Of course, this does not mean that the site visitors will continue being served the same content over and over again, as any change on any of the web pages is reflected in the content that the Varnish platform keeps in its system memory.

Varnish in Shared Hosting

You can take advantage of Varnish’s potential and improve the speed of your websites regardless of the shared hosting plan that you’ve picked and you can add and configure the data caching platform with a few mouse clicks via the simple-to-work-with GUI offered by our avant-garde Hepsia Control Panel. In the meantime, you will be able to select two separate things – how many websites will employ the Varnish caching platform, i.e. the number of instances, and how much content will be cached, in other words – the amount of system memory. The latter comes in increments of 32 megabytes and is not tied to the number of instances, so you can use more instances with less memory and vice versa. If you have a lot of content on a given site and you attract numerous website visitors, more system memory will give you better results. You may also consider using a dedicated IP for the sites that will use the Varnish caching platform. Hepsia will provide you with easy 1-click buttons for disabling or rebooting any instance, for clearing the cache associated with each Internet site and for checking exhaustive system logs.

Varnish in Semi-dedicated Servers

The Varnish caching platform is included in the standard set of services that you will obtain in case you choose to host your websites in a semi-dedicated server account. You can enable it for any of your Internet sites via our innovative Hepsia Control Panel. The default memory that the Varnish platform can use to cache content is 64 MB, but if 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, in other words – the number of the Internet sites that can use this caching platform at the same time. As these two things are not linked to each other, you can use a few instances with the default memory or you can order more memory in increments of 32 MB and use all of it for a single site. The Varnish caching platform performs best when you assign a dedicated IP to the Internet sites that utilize its power. The Hepsia Control Panel will offer you a simple means of restarting any instance. In addition, you will be able to delete the cached data with only one single click of the mouse.

Varnish in VPS Servers

We offer Varnish with all of the Hepsia-equipped Linux VPS servers, so if you buy a VPS with this hosting Control Panel, you’ll be able to make use of the caching platform at no extra fee. The Varnish platform can use different amounts of system memory for data caching purposes depending on the particular sever setup that you have picked during the signup procedure, but nevertheless, this amount won’t be less than several hundred MB. This is more than enough to boost the overall performance of a number of resource-intensive sites, so the better web page load speeds and the less load on the virtual machine will be discernible. The result may not be apparent immediately, since Varnish will need a certain amount of time to cache the content that users browse, but soon after you activate it, you’ll feel its full potential. This caching platform will permit you to use a less powerful Virtual Private Server and to pay less cash to get the same performance you’d get with a more powerful virtual machine without Varnish.

Varnish in Dedicated Servers

When you need a more powerful hosting solution and you order any of the Linux dedicated web hosting plans offered by our company, you will be able to use the Varnish content caching platform to optimize the performance of your sites at no additional charge as long as the dedicated server is ordered with our next-generation Hepsia Control Panel. Its easy-to-navigate GUI will permit you to keep track of system processes, to delete the cached contents or to restart any instance with one single mouse click. The minimum amount of system memory that Varnish can employ to cache website content is 3 gigabytes, which is quite enough for a vast number of large-scale Internet sites, so your server will be able to handle a colossal system load while your site visitors are enjoying a seamless browsing experience. Since your machine will include several different dedicated IP addresses, you will be able to make use of Varnish’s maximum capacity.
