Varnish is a web application accelerator platform, which caches info for the sake of faster access. It is occasionally referred to as a caching HTTP reverse proxy as well and it works between a web server and an Internet browser. When a visitor accesses a given web page, its content is requested by the browser, and then the server processes this browser request and delivers the needed content. If Varnish is enabled for a given website, it will cache its pages at the very first request and if the user visits a cached page once again, the info will be delivered by the accelerator platform instead of the web server. The boosted speed is a result of the much faster response speed that Varnish offers compared to any server software. At the same time, this doesn’t mean that the visitors will keep being served the exact same content over and over again, because any update on any of the web pages is reflected in the content that Varnish keeps in its system memory.
Varnish in Cloud Hosting
Varnish is offered as an optional upgrade with all our Linux cloud hosting packages. You can add it to your website hosting account via the Hepsia hosting Control Panel, which comes with all shared packages and you will get a truly simple-to-work-with graphical interface, which will give you full control over the caching system. Using 1-click fast-access controls, you can reboot or stop any of the instances, i.e. Varnish will no longer be activated for a certain site. You can also see a comprehensive system log or delete the cache associated with any of the websites. When you add Varnish to your hosting package, you will be able to select the total amount of system memory that will be available to you for data caching purposes and how many websites will use Varnish. You can always get more memory in increments of 32 megabytes and, for best performance, you can set a dedicated IP for the websites that will use Varnish. This will enable you to take full advantage of your sites and to have numerous happy users.
Varnish in Semi-dedicated Hosting
Varnish is included by default with all Linux semi-dedicated packages offered by us and you can use it for load distribution purposes. It is available in your Hepsia Control Panel. The Varnish platform comes with 64 MB of system memory for cached data storing purposes and you can employ it with any website that you host in your semi-dedicated account. In case you are in need of more than that, you can increase the system memory quota. The memory itself is offered in increments of 32 MB in the Control Panel’s Upgrades section. The very same Upgrades section will enable you to create more instances too, in case you want to use Varnish with more Internet sites. The two things can be ordered independently – you can cache the content of a single resource-consuming Internet site or run several different sites with the default memory allowance. You can take full advantage of Varnish if you use a dedicated IP address and you can get one with your semi-dedicated server plan as well. Hepsia will grant you total control over the caching platform and, with no more than one click of the mouse, you will be able to clear the cached content, to see a log file or to reboot an instance.
Varnish in VPS
We offer Varnish with all of the Hepsia-managed Linux VPS packages, so if you get a VPS with this web hosting Control Panel, you’ll be able to make use of the caching platform at no additional fee. The Varnish platform can utilize different amounts of memory for content caching purposes depending on the particular configuration that you have selected during the server order process, but at any rate, this amount will not be less than several hundred megabytes. This is more than enough to boost the work of several different traffic-heavy Internet sites, so the better site browsing speeds and the less load on the server will be discernible. The effect may not be distinguishable right away, since Varnish will require some time to cache the site content that visitors browse, but shortly after you set it up, you will feel its full capacity. This caching platform will permit you to use a less powerful VPS server and to give less cash to get the very same performance you would get with a more powerful machine without Varnish.
Varnish in Dedicated Hosting
If you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish data caching platform at no additional fee and you will have complete control over it via a truly user-friendly interface – you will be able to start, to delete or to restart an instance, to check a comprehensive system log, to clear the cached content associated with any website and much, much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you host resource-swallowing sites with an immense number of visitors, you’ll notice the considerably faster page load speeds and the less load on your dedicated server. This will become a fact shortly after you start using Varnish, since it will require a certain amount of time to cache the website content that users browse. You can take full advantage of the platform’s capability if the websites that are using it also use a dedicated IP address, but owing to the fact that your dedicated server includes several IPs by default, you won’t have to pay anything on top of your monthly charge for the server itself.
