Varnish is a web accelerator, which has been gaining a lot of popularity in recent years, because it can increase the loading speed of any Internet site, sometimes even by 100%, depending on the content. This tool is sometimes called an HTTP reverse proxy as well and is used to lower the overall load on the physical server and to improve the access speed for the site visitors. Each time a visitor loads a page on a specific Internet site, the web browser request is taken care of by the web server and the requested information is sent as a response. If the Varnish accelerator is activated, it caches the web pages that the website visitor browses and in case any of them is opened once more, it is fetched by Varnish and not by the web server directly. The improvement in the overall 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 users. In case any content is updated meanwhile, the cached pages will also be updated the next time somebody opens them.
Varnish in Shared Web Hosting
Varnish is available as an optional upgrade with each of our shared web hosting service. You can add it to your account via the Hepsia Control Panel, which is offered with all shared plans and you will get an exceptionally simple-to-use interface, which will give you complete control over the content caching system. Using 1-click fast-access buttons, you can restart or disable any of the instances, i.e. Varnish will no longer be activated for a specific Internet site. You can also see a detailed log or clear the cache associated with any of the sites. When you add Varnish to your shared hosting package, you’ll be able to select 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 order more memory in increments of 32 MB and, for optimal performance, you can assign a dedicated IP to the sites that will use Varnish. This will permit you to get the most out of your Internet sites and to have a lot of satisfied site users.
Varnish in Semi-dedicated Servers
Varnish is offered as standard with all Linux semi-dedicated hosting service that we offer and you can use it for workload balancing purposes. It is available in your Hepsia hosting Control Panel. The caching platform comes with 64 MB of system memory for cached data storing purposes and you can employ it with any Internet site that you host in the semi-dedicated server account. In case you are in need of more, you can increase the system memory allocation. The memory itself is available in increments of 32 megabytes in the Control Panel’s Upgrades section. The very same Upgrades section will enable you to enable more instances too, if you’d like to use the Varnish caching platform with more websites. The two things can be ordered independently – you can cache the content of one regularly visited Internet site or use a number of websites with the default memory allocation. You can get the most out of Varnish in case you have a dedicated IP and you can order one with your semi-dedicated server package as well. Hepsia will give you complete control over the platform and, with no more than one mouse click, you’ll be able to clear the cached data, to check a log file or to restart an instance.
Varnish in VPS Servers
You can use Varnish with all our VPS server packages at no additional charge, since the platform is pre-installed and is available by default. The sole condition is that the Virtual Private Server must come with the Hepsia hosting Control Panel, through which you will be able to activate Varnish for any of your websites with only a few mouse clicks. Each VPS package includes a different amount of memory for data caching purposes, but you will have no less than several hundred megabytes, which is quite enough even for several resource-demanding websites. Shortly after you enable Varnish, it’ll begin caching the content that your visitors access, so you will notice the much faster page load speeds and the decreased load on your virtual server very soon. The platform will allow you to use a less costly virtual machine, since you will not require that many resources to guarantee the correct operation of your websites even if you manage large sites with lots of visitors. Optimum results are achieved if the websites which use the Varnish caching platform also use a dedicated IP.
Varnish in Dedicated Servers
All Linux dedicated servers that are ordered with the custom Hepsia web hosting Control Panel come with Varnish, which is one of the pre-installed software platforms that you’ll get with the machine. The Varnish caching platform can be enabled and managed without efforts via Hepsia’s user-friendly interface and, with no more than one single mouse click, you can check a detailed system log, create or restart an instance, delete the cached data for any Internet site and much more. Soon after you configure the Varnish platform for a given domain or sub-domain, it will begin caching the webpages opened by your visitors and as soon as it has cached enough content, you’ll perceive a significantly better website performance plus a lowered server load. With Varnish-dedicated memory starting at 3 GB, you’ll be able to use the software platform for workload distribution purposes even if you host an enormous number of websites on your machine.
