Varnish is a web accelerator platform, which caches information for faster access. It’s sometimes referred to as a caching HTTP reverse proxy as well and it interacts between a web server and its users. When a site visitor loads a given web page, its content is requested by the browser, and then the web server processes this request and sends back the necessary info. If Varnish is activated for a certain site, it will cache the pages at the first visit and in case the visitor opens a cached page for a second time, the content will be delivered by the accelerator platform instead of the web server. The increased load speed is an end result of the much faster response speed that Varnish offers as compared to any web server software. At the same time, this does not mean that the visitors will keep seeing the same content again and again, as any change on any of the pages is reflected in the content that Varnish saves in its memory.
Varnish in Shared Hosting
Varnish is available as an optional upgrade with each of our shared hosting plans. You can add it to your web hosting account via the Hepsia hosting Control Panel, which comes with all shared hosting packages and you’ll get an exceptionally simple-to-use graphical interface, which will give you complete control over the data caching system. Using one-click fast-access controls, you can reboot or stop any of the instances, in other words – Varnish will no longer work for a particular website. You can also view an in-depth log file or delete the cache for any of the websites. When you add Varnish to your web hosting plan, you’ll be able to choose the maximum amount of system memory that will be available to you for content caching purposes and how many websites will use Varnish. You can always add more memory in increments of 32 megabytes and, for top performance, you can allocate a dedicated IP address to the websites that will use Varnish. This will enable you to get the most out of your Internet sites and to have lots of happy site visitors.
Varnish in Semi-dedicated Servers
All our semi-dedicated plans include Varnish by default, so you can take advantage of the web accelerator tool and boost the loading speed of any site that you host on our semi-dedicated servers. You will get 64 MB of system memory particularly for Varnish at no additional fee and you’ll be able to create an instance with no more than a few mouse clicks via the Hepsia hosting Control Panel, which comes with the semi-dedicated server plans. If you need more memory, the latter is offered in increments of 32 megabytes in the Upgrades section of the Control Panel and it will be at your disposal right away. You can also order more instances as an upgrade, so you can choose if a lot of data will be cached for one site or if the memory will be utilized by different websites. Hepsia will enable you to restart or to shut down any instance, to see the system log for it or to delete the cached files using single-click buttons. To get the most out of Varnish, you can assign a dedicated IP address to the Internet sites that will use it.
Varnish in VPS Servers
You can take advantage of Varnish with any of our VPS server plans at no additional fee, as the content caching platform is pre-installed and is offered by default. The one and only condition is that the virtual server must be ordered with the Hepsia hosting Control Panel, through which you’ll be able to activate Varnish for any of your Internet sites with just a couple of mouse clicks. Each VPS package comes with a different amount of memory for data caching purposes, but you’ll get at least several hundred MB, which is enough even for several traffic-heavy sites. Shortly after you set up Varnish, it’ll begin caching the content that your visitors open, so you will notice the considerably faster Internet site load speeds and the lowered load on the Virtual Private Server very soon. The Varnish caching platform will allow you to use a less pricey VPS, as you won’t need that many resources to sustain the proper operation of your sites even if you manage large-sized Internet sites with many visitors. Optimal results are achieved if the Internet sites which use the Varnish caching platform use also a dedicated IP.
Varnish in Dedicated Servers
If you order a dedicated server with the Hepsia hosting Control Panel, you will obtain the Varnish platform at no extra charge and you’ll exert total control over it via a rather simple-to-work-with graphical interface – you will be able to start, to delete or to restart an instance, to see an exhaustive log, to clear the cached content associated with any website and much more. The Varnish platform will have several GB of virtual memory at its disposal, so even if you’ve got large-sized Internet sites with a huge number of visitors, you will notice the significantly faster page load speeds and the decreased load on your server. This will become a fact shortly after you begin using Varnish, as it will need some time to cache the website content that people browse. You can make the most of the platform’s potential if the Internet sites that are using it use also a dedicated IP address, but since your dedicated server comes with a couple of IP addresses by default, you will not have to pay anything on top of your monthly charge for the server itself.
