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 Internet site, at times even by one hundred percent, based on the content. This tool is sometimes referred to as an HTTP reverse proxy too and is used to lower the overall load on the physical machine and to enhance the access speed for the website visitors. Each time a visitor opens a page on a particular site, the browser request is handled by the web server and the requested content is served as a reply. If the Varnish accelerator is activated, it caches the pages that the website visitor opens and in case any of them is accessed once again, it is fetched by Varnish and not by the server directly. The performance boost is due to the fact that the accelerator handles the web requests considerably faster than any web server, which leads to much faster browsing speeds for the website visitors. In case any data is updated meanwhile, the cached pages will also be updated the next time someone accesses them.
Varnish in Cloud Hosting
If you host your Internet sites under a cloud hosting account with our company, you’ll be able to activate Varnish with a few mouse clicks through your hosting Control Panel. The data caching platform is available as an upgrade with all our packages and you can select the number of the websites that will use it and the maximum amount of system memory that will be used for the cached content. The two upgradeable features in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they’re not directly linked to each other, so you can choose whether you want a lot of memory for one single large-scale website or less memory for multiple smaller ones. You can unleash the full potential of the Varnish caching platform in case the sites use a dedicated IP. Using the Control Panel, you can swiftly start/restart/delete an instance, clear the cached contents individually for each website which uses the Varnish platform or check an in-depth system log file.
Varnish in Semi-dedicated Servers
Varnish is included by default with all semi-dedicated hosting plans offered by us and you can use it for workload balancing purposes. It is available in your Hepsia Control Panel. The content caching platform comes with 64 megabytes of system memory for cached data storing purposes and you can employ it with any website that you host in your semi-dedicated server account. If you’re in need of more, you can increase the memory quota. The memory itself is offered in increments of 32 megabytes through the Control Panel’s Upgrades section. The very same section will allow you to add more instances too, in case you’d like to use the Varnish platform with more websites. The two things can be ordered separately – you can cache the content of one single resource-absorbing Internet site or run several websites with the default memory allocation. You can take full advantage of Varnish in case you’ve got a dedicated IP address and you can order one with your semi-dedicated server plan as well. Hepsia will grant you full control over the platform and, with no more than one mouse click, you’ll be able to delete the cached files, to view a system log or to reboot an instance.
Varnish in VPS Servers
You can take full advantage of the load balancing capabilities of Varnish with all our VPS servers in case you choose Hepsia as your Control Panel. The Varnish caching platform is offered by default and the memory that it will be able to use to cache your site content is dependent upon the specific Virtual Private Server package that you have selected, but even with the less powerful packages, you will have at least several hundred MB of system memory at your disposal exclusively for data caching purposes. This amount is sufficient enough to improve the overall performance of multiple sites. It will take some time for you to see the results, since Varnish caches the content that visitors browse, but shortly after that you’ll notice the substantially less server load and the enhanced site browsing speed. Varnish will allow you to make use of a lower-end Virtual Private Server plan for websites which would normally need a more costly hosting solution.
Varnish in Dedicated Servers
If you want a powerful web hosting solution and you order any of the Linux dedicated web hosting plans that we are offering, you will be able to use the Varnish content caching platform to improve the work of your websites at no extra cost as long as the dedicated server is ordered with our cutting-edge Hepsia Control Panel. Its easy-to-navigate GUI will allow you to keep an eye on system processes, to clear the cache or to restart any instance with one single mouse click. The minimum amount of system memory that the caching platform can use to cache Internet site content is three gigabytes, which is quite enough for an enormous selection of popular websites, so your dedicated server will be able to handle a massive load while your Internet site visitors are having a smooth browsing experience. As your dedicated machine will come with a number of dedicated IP addresses, you’ll be able to use Varnish’s full potential.
