Varnish is a web app accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the loading speed of any website, at times even by one hundred percent, based on the content itself. This tool is sometimes called an HTTP reverse proxy as well and is used to reduce the overall load on the physical server and to boost the browsing speed for the website visitors. Anytime a visitor accesses a page on a certain Internet site, the web browser request is processed by the web server and the requested info is served as a reply. If the Varnish accelerator is enabled, it caches the web pages that the visitor opens and in case any of them is loaded for a second time, it is fetched by Varnish and not by the web server directly. The boost in the performance comes from the fact that the accelerator handles the browser requests tremendously quicker than any web server, which leads to much faster browsing speeds for the visitors. If any data is edited meanwhile, the cached webpages will also be updated the next time somebody tries to open them.
Varnish in Shared Hosting
Varnish is available as an optional upgrade with each of our Linux shared hosting. You can add it to your website hosting account via the Hepsia hosting Control Panel, which comes with all shared web hosting plans and you will get a quite easy-to-work-with GUI, which will give you complete control over the caching platform. Using one-click quick-access controls, you can reboot or stop any of the instances, in other words – Varnish will no longer work for a certain site. You can also view an elaborate system log file or erase the cache for any of the Internet sites. When you add Varnish to your web hosting package, you will be able to choose the total amount of memory that will be available to you for content caching purposes and how many sites will use Varnish. You can always order more memory in increments of 32 MB and, for optimum performance, you can get a dedicated IP address for the sites that will use Varnish. This will permit you to get the most out of your sites and to have many happy website users.
Varnish in Semi-dedicated Servers
The Varnish data caching platform is an essential part of the standard set of services that you’ll obtain in case you choose to host your Internet sites in a semi-dedicated server account. You can enable it for any of your sites through our next-generation Hepsia Control Panel. The default amount of memory that Varnish can use to cache content is 64 megabytes, but if you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this platform simultaneously. Since these two features are not tied to each other, you can use a few websites with the default memory or you can get more memory in increments of 32 MB and use all of it for a single Internet site. The Varnish caching platform works best if you allocate a dedicated IP to the websites that utilize its power. Hepsia will provide you with an easy way of rebooting any instance. Furthermore, you will be able to delete the cached data with only one click.
Varnish in VPS Servers
The Varnish caching platform is included by default with all VPS servers that we’re offering given that the VPS server is ordered with the Hepsia Control Panel, so you can enhance the work of your sites with just a few clicks. The more powerful the package, the more memory will be available to Varnish, but even with a lower-end plan, the platform will be able to utilize several hundred megabytes, so even if you own several different Internet sites, you’ll notice a great decrease in the overall server load and a significantly better web page load speed. The Varnish caching platform will have to work for a while as the users browse the site and once the content has been cached, you will notice the results. One of the benefits of using Varnish is that a lower-end and less expensive VPS package will do the very same job as a more pricey one without the caching platform, so not only will your websites work substantially better, but you’ll also spare some money.
Varnish in Dedicated Servers
If you order a dedicated server with the Hepsia Control Panel, you will obtain the Varnish platform at no extra cost and you will have complete control over it through a rather simple-to-navigate interface – you’ll be able to start, to remove or to reboot an instance, to see a detailed log, to clear the cached content for any Internet site and much, much more. Varnish will have several gigabytes of system memory at its disposal, so even if you run resource-absorbing sites with plenty of visitors, you will notice the significantly better website loading times and the reduced load on your server. This will become a fact shortly after you begin using the Varnish platform, since it will need a certain amount of time to cache the website content that visitors request. You can take full advantage of the platform’s capability if the websites that are using it also use a dedicated IP, but owing to the fact that your server comes with several IPs by default, you won’t need to pay anything on top of your monthly charge for the server itself.
