Varnish is a web application accelerator tool, which has been gaining a lot in popularity lately, because it can increase the speed of any website, at times even by 100 percent, depending on the content itself. This tool is occasionally called a caching HTTP reverse proxy as well and is used to decrease the overall load on the physical machine and to increase the access speed for the website visitors. Each time a visitor opens a page on a particular site, the web browser request is taken care of by the web server and the requested content is served as a reply. If Varnish is enabled, it caches the web pages that the website visitor opens and if any of them is accessed once more, it is fetched by Varnish and not by the web server directly. The performance increase is due to the fact that the accelerator processes the web requests substantially faster than any web server, which leads to much faster browsing speeds for the website visitors. In case any content is modified meanwhile, the cached pages will also be ‘refreshed’ the next time somebody opens them.

Varnish in Web Hosting

Varnish is offered as an optional upgrade with all our Linux web hosting. You can add it to your hosting account from the Hepsia Control Panel, which comes with all shared hosting plans and you’ll get a truly simple-to-use graphical interface, which will grant you full control over the caching system. Using one-click fast-access controls, you can restart or disable any of the instances, in other words – Varnish will no longer work for a given Internet site. You can also see a detailed log file or erase the cache for any of the websites. When you add Varnish to your web hosting plan, you will be able to select the maximum amount of 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 megabytes and, for top performance, you can allocate a dedicated IP to the sites that will use Varnish. This will permit you to take full advantage of your sites and to have many happy website users.

Varnish in Semi-dedicated Servers

Varnish is included as standard with all semi-dedicated plans offered by our company and you can use it for workload distribution purposes. It is available in your Hepsia hosting Control Panel. The Varnish caching platform comes with 64 MB of system memory for cached data storing purposes and you can employ it with any Internet site that you host in the semi-dedicated account. In case you need more, you can increase the memory allowance. The memory itself is available in increments of 32 MB through the Upgrades section of the Control Panel. The same section will permit you to activate more instances too, if you want to use Varnish with more sites. The two upgrades can be added independently – you can cache the content of one large-sized Internet site or use several different sites with the default memory allowance. You can get the most out of the Varnish platform in case you have a dedicated IP address and you can get one with your semi-dedicated server package as well. The Hepsia Control Panel will give you complete control over the platform and, with no more than a click, you will be able to clear the cached files, to check a system log or to restart an instance.

Varnish in VPS Servers

You can take advantage of Varnish with any of our VPS server plans at no additional fee, since the platform is pre-installed and is available by default. The sole precondition is that the virtual server must be ordered with the Hepsia Control Panel, through which you will be able to set up Varnish for any of your Internet sites with just a few mouse clicks. Each package features a different amount of system memory for caching purposes, but you will get no less than several hundred megabytes, which is quite sufficient even for multiple resource-demanding sites. Shortly after you activate the Varnish platform, it will begin caching the content that your website visitors open, so you’ll notice the significantly better website load times and the reduced load on your virtual server in no time. The caching platform will permit you to use a less pricey server, since you will not require that many resources to warrant the uninterrupted operation of your Internet sites even if you have resource-demanding sites with a lot of visitors. Optimal results are accomplished if the websites that use the Varnish platform use also a dedicated IP address.

Varnish in Dedicated Servers

If you need a more powerful web hosting solution and you purchase one of the Linux dedicated web hosting plans offered by us, you can use the Varnish caching platform to optimize the work of your Internet sites at no additional cost on the condition that the dedicated machine is ordered with our next-generation Hepsia hosting Control Panel. Its easy-to-navigate GUI will enable you to keep track of platform processes, to clear the cached contents or to reboot any instance with one single mouse click. The minimum amount of system memory that Varnish can use to cache Internet site content is 3 GB, which is more than enough for a large selection of high-demand Internet sites, so your server will be able to handle an immense load while your visitors are enjoying a smooth web browsing experience. Since your dedicated server will include several different dedicated IPs, you’ll be able to use Varnish’s maximum potential.
