Varnish is a website accelerator platform, which caches information for faster access. It is occasionally referred to as an HTTP reverse proxy too and it works between a web server and its users. When a visitor opens a given web page, its content is requested by the browser, and then the server handles this browser request and delivers the needed information. If Varnish is enabled for a certain website, it will cache the pages at the first request and if the user visits a cached page once more, the info will be delivered by the accelerator platform and not by the web server. The improved loading speed is a result of the considerably faster response speed that the Varnish platform offers compared with any server software. At the same time, this does not mean that the visitors will continue being served the exact same content again and again, as any modification on any of the web pages is reflected in the content that the Varnish platform saves in its memory.
Varnish in Cloud Website Hosting
Varnish comes as an optional upgrade with all our cloud website hosting packages. You can add it to your hosting account via the Hepsia Control Panel, which is available with all shared web hosting packages and you’ll get a quite easy-to-work-with GUI, which will give you full control over the data caching platform. Using one-click fast-access buttons, you can restart or disable any of the instances, i.e. Varnish will no longer be activated for a given Internet site. You can also view a comprehensive system log or erase the cache for any of the websites. When you add Varnish to your hosting plan, you’ll be able to choose the total amount of system memory that will be available to you for caching purposes and the number of the websites that will use Varnish. You can always add more memory in increments of 32 megabytes and, for optimum performance, you can set a dedicated IP for the sites that will use Varnish. This will allow you to get the most out of your websites and to have numerous satisfied visitors.
Varnish in Semi-dedicated Hosting
Varnish is an essential part of the default set of services that you will receive if you choose to host your websites under a semi-dedicated server account. You can activate it for any of your websites via our advanced Hepsia Control Panel. The default amount of memory that Varnish can use to cache content is 64 megabytes, but in case you decide that you want more, you can upgrade this amount from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the websites that can use this caching platform at the same time. Since these two features are not linked to each other, you can use a couple of Internet sites with the default memory or you can order more memory in increments of 32 megabytes and use all of it for a single site. The Varnish caching platform works best if you use a dedicated IP for the sites that utilize its power. The Hepsia Control Panel will offer you an easy way of restarting any instance. Also, you’ll be able to clear the cached contents with just one single mouse click.
Varnish in VPS
We offer Varnish with all of the Hepsia-equipped Linux VPS, so if you order a VPS with this hosting Control Panel, you’ll be able to take full advantage of the caching platform at no extra fee. The Varnish platform can utilize different amounts of system memory for content caching purposes depending on the particular Virtual Private Server package that you’ve selected during the signup procedure, but nevertheless, this amount will not be less than several hundred MB. This is more than enough to improve the overall performance of several different resource-hungry Internet sites, so the faster web page load speeds and the lowered load will be discernible. The effect may not be evident momentarily, as the Varnish platform will require some time to cache the site content that users browse, but soon after you activate it, you’ll observe its full potential. This platform will permit you to use a less powerful VPS and to pay less cash to get the very same performance you would get with a more powerful machine without Varnish.
Varnish in Dedicated Hosting
In case you order a dedicated server with the Hepsia Control Panel, you will acquire the Varnish platform at no extra fee and you will exert complete control over it via an amazingly easy-to-navigate graphical interface – you will be able to start, to delete or to reboot an instance, to view a detailed system log, to delete the cache for any Internet site and much, much more. The Varnish caching platform will have several GB of system memory at its disposal, so even if you own traffic-consuming Internet sites with multiple visitors, you will notice the considerably better website loading speeds and the decreased load on your server. This will become a fact shortly after you start using Varnish, as it will need a certain amount of time to cache the pages that people browse. You can get the most out of the platform’s potential in case the sites that are using it also use a dedicated IP, but since your server includes a couple of IP addresses by default, you won’t have to pay anything on top of your monthly charge for the server itself.
