Varnish is a web application accelerator, which has been gaining a lot in popularity in recent years, as it can increase the load speed of any website, sometimes even by 100 percent, based on the content itself. This tool is occasionally called a caching HTTP reverse proxy too and is used to reduce the overall load on the physical machine and to increase the browsing speed for the site visitors. Every time a visitor accesses a page on a specific Internet site, the browser request is processed by the web server and the requested data is returned as a reply. If the Varnish accelerator is activated, it caches the pages that the website visitor browses and in case any of them is loaded once more, it’s served by Varnish and not by the web server directly. The boost in the performance comes from the fact that the accelerator processes the web requests considerably faster than any web server, which results in much faster browsing speeds for the visitors. In case any content is changed meanwhile, the cached webpages will also be ‘refreshed’ the next time someone tries to open them.
Varnish in Cloud Hosting
Varnish is offered as an optional upgrade with all our cloud plans. You can add it to your web hosting account via the Hepsia Control Panel, which is offered with all shared web hosting packages and you’ll get a very user-friendly GUI, which will grant you complete control over the data caching system. Using one-click quick-access buttons, you can reboot or delete any of the instances, in other words – Varnish will no longer work for a particular site. You can also view an exhaustive log or erase the cache for any of the sites. When you add Varnish to your hosting plan, you’ll be able to select the maximum amount of memory that will be available to you for data caching purposes and the number of the sites that will use Varnish. You can always order more memory in increments of 32 megabytes and, for optimum performance, you can set a dedicated IP address for the sites that will use Varnish. This will allow you to get the most out of your sites and to have plenty of gratified website users.
Varnish in Semi-dedicated Servers
The Varnish data caching platform is included in the default set of services that you’ll acquire when you decide to host your Internet sites in a semi-dedicated server account. You can activate it for any of your Internet sites through our leading-edge Hepsia hosting Control Panel. The default memory that the Varnish caching platform can use to cache data is 64 megabytes, but in case you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this platform at the same time. As these two things are not tied to each other, you can use a couple of Internet sites with the default memory or you can get more memory in increments of 32 megabytes and use all of it for one single site. The Varnish caching platform performs best when you allocate a dedicated IP address to the sites that utilize its power. Hepsia will provide you with an easy way of restarting any instance. What’s more, you will be able to delete the cached files with just one single click.
Varnish in VPS Servers
We offer Varnish with all Hepsia-equipped VPS plans, so if you obtain a VPS with this hosting Control Panel, you will be able to make use of the caching platform at no extra charge. The Varnish platform can use different amounts of system memory for data caching purposes based on the very package that you’ve chosen on the order form, but in any case, this amount won’t be less than several hundred MB. This is quite enough to boost the work of several different large-sized Internet sites, so the better page loading speeds and the lowered load on the virtual server will be noticeable. The result may not be detectable instantly, as the Varnish platform will require a certain amount of time to cache the website content that people browse, but soon after you activate it, you will feel its full capacity. This caching platform will permit you to use a lower-end server and to give less money to get the very same performance you would get with a more powerful virtual machine without Varnish.
Varnish in Dedicated Servers
You can use Varnish to accelerate the speed of any website that is hosted on a dedicated server with us when the Hepsia hosting Control Panel is pre-installed on it. Not only will you get the caching platform ready to be used at no extra cost, but you’ll also exert complete control over it through the Hepsia Control Panel’s simple-to-work-with graphical interface. It’ll take just a click to start or stop an instance or to clear the cached content associated with any site that is using Varnish and if you are more proficient, you can also view the platform’s logs. Varnish comes with at least 3 gigabytes of system memory for web content caching purposes, so even in case you host an enormous number of websites on your dedicated machine and they all use the caching platform, the difference in their overall performance will be obvious. You’ll just need to wait for a little while till Varnish caches whatever web pages the visitors open on their end. The platform performs best when the sites use a dedicated IP address, but owing to the fact that our servers come with 3 free IPs, you’ll have all that you need.
