Varnish is a web app accelerator tool, which has been gaining a lot in popularity lately, as it can increase the speed of any website, sometimes even by 100%, depending on the content itself. This tool is sometimes called an HTTP reverse proxy as well and is used to decrease the overall server load and to increase the access speed for the site visitors. Each time a visitor accesses a page on a certain website, the web browser request is handled by the web server and the requested content is sent as a response. If Varnish is activated, it caches the web pages that the visitor opens and if any of them is accessed once again, it’s delivered by Varnish and not by the web server directly. The performance increase comes from the fact that the accelerator processes the browser requests substantially quicker than any web server, which leads to much faster browsing speeds for the site visitors. In case any data is updated in the meantime, the cached web pages will also be ‘refreshed’ the next time somebody attempts to access them.
Varnish in Shared Web Hosting
Varnish is offered as an optional upgrade with each of our shared web hosting. You can add it to your hosting account through the Hepsia hosting Control Panel, which comes with all shared hosting packages and you will get a rather user-friendly interface, which will grant you full control over the caching platform. Using one-click fast-access buttons, you can reboot or deactivate any of the instances, in other words – Varnish will no longer work for a given Internet site. You can also view a comprehensive system log file or clear the cache for any of the Internet sites. When you add Varnish to your shared hosting plan, you’ll be able to select the total amount of system memory that will be at your disposal for content 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 best performance, you can allocate a dedicated IP to the sites that will use Varnish. This will permit you to take full advantage of your websites and to have numerous gratified website users.
Varnish in Semi-dedicated Servers
The semi-dedicated plans that we’re offering will allow you to employ Varnish as soon as your new semi-dedicated server account has been opened, since the platform is available by default. 64 megabytes of system memory will be assigned to Varnish the second your account is activated, so you can take advantage of this load balancing software once your site has been built. If you are in need of more memory, you can add 32 MB at a time from the Upgrades section of the Hepsia hosting Control Panel and it will be assigned to your semi-dedicated machine in a flash. You can also increase the number of the Internet sites that use Varnish, or the so-called ‘instances’, which are not directly bound to the amount of system memory that you use, which means that you will enjoy more flexibility. The caching platform will substantially lower the load produced by your websites, so your website visitors can enjoy fast-loading web pages. You’ll be able to manage the Varnish platform without efforts through your Hepsia Control Panel using fast-access buttons. You’ll be able to start/delete any of the instances that you have, to clear the cached data associated with any of your sites or to view system logs.
Varnish in VPS Servers
You can use the workload balancing capabilities of Varnish with any of our Linux VPS plans if you select Hepsia as your hosting Control Panel. The Varnish caching platform is available by default and the amount of memory that it’ll be able to utilize to cache your site content depends on the particular VPS package that you have selected, but even with the less powerful packages, you’ll have at least several hundred megabytes of memory at your disposal only for caching purposes. This amount is sufficient enough to boost the performance of multiple websites. It’ll take some time for you to notice the effects, as Varnish caches the content that visitors browse, but soon thereafter you’ll notice the substantially reduced load on the Virtual Private Server and the improved site load speed. Varnish will permit you to make use of a lower-end package for Internet sites that would normally require a more expensive hosting service.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll get Varnish at no extra fee and you will have complete control over it via a rather intuitive graphical interface – you’ll be able to start, to terminate or to reboot an instance, to check an elaborate log, to clear the cached files for any site and much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you have traffic-intensive websites with a large number of visitors, you’ll notice the considerably better web page load times and the decreased load on the dedicated machine. This will become a fact shortly after you begin using the Varnish platform, as it will need some time to cache the content that users request. You can get the most out of the platform’s capacity if the sites that are using it use also a dedicated IP, but considering the fact that your dedicated server comes with several IP addresses by default, you won’t need to pay anything on top of the monthly fee for the server itself.
