Varnish is a web accelerator platform, which caches information for the sake of faster access. It is sometimes called an HTTP reverse proxy as well and it interacts between a web server and an Internet browser. When a website visitor accesses a specific page, the content is requested by the Internet browser, and then the web server handles this browser request and sends back the necessary data. If Varnish is enabled for a given site, it will cache the pages at the first visit and in case the visitor visits a cached page once again, the info will be delivered by the accelerator platform instead of the server. The accelerated load speed is a result of the substantially faster response time that Varnish offers as compared to any web server software. At the same time, this doesn’t mean that the users will continue seeing the same content again and again, because any change on any of the pages is reflected in the content that the Varnish platform caches in its system memory.
Varnish in Shared Web Hosting
If you host your websites under a shared web hosting account with us, you will be able to add Varnish with a couple of clicks of the mouse through your hosting Control Panel. The platform is offered as an optional upgrade with all our hosting plans and you can select how many websites will use it and the total amount of system memory that will be used for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they aren’t tied directly to each other, so you can decide if you want lots of memory for one large-scale website or less memory for multiple smaller ones. You can unlock the full potential of the Varnish platform if the websites use a dedicated IP address. With the hosting Control Panel, you can quickly start/restart/discontinue an instance, clear the cached files independently for each website that employs the Varnish platform or check a detailed log.
Varnish in Semi-dedicated Hosting
Varnish is included by default with all semi-dedicated hosting that we offer and you can use it for workload balancing purposes. It is available in your Hepsia hosting Control Panel. The Varnish data caching platform comes with 64 MB of system memory for cached content storing purposes and you can employ it with any site that you host in the account. If you need more than that, you can increase the memory quota. The memory itself is available in increments of 32 megabytes in the Upgrades section of the Control Panel. The very same Upgrades section will allow you to enable more instances too, in case you would like to use the Varnish caching platform with multiple sites. The two things can be added independently – you can cache the content of one single resource-absorbing website or use a number of sites with the default memory allowance. You can get the most out of the Varnish caching platform if you’ve got a dedicated IP address and you can order one with your semi-dedicated server package as well. The Hepsia Control Panel will grant you total control over the caching platform and, with no more than one mouse click, you will be able to delete the cached files, to view a system log file or to restart an instance.
Varnish in VPS
You can use Varnish with each of our virtual private server plans at no additional fee, as the content caching platform is pre-installed and is available by default. The only prerequisite is that the server must come with the Hepsia Control Panel, through which you will be able to activate Varnish for any of your websites with only a couple of clicks. Each VPS package features a different amount of memory for content caching purposes, but you’ll have minimum several hundred MB, which is sufficient enough even for multiple regularly visited sites. Shortly after you activate the Varnish platform, it will begin caching the content that your visitors open, so you will notice the substantially better page loading speeds and the reduced load on the VPS server in no time. The platform will allow you to use a less expensive server, since you won’t require that many resources to warrant the proper operation of your websites even if you have large-size websites with many visitors. Optimal results are accomplished if the websites which use the Varnish platform also use a dedicated IP.
Varnish in Dedicated Hosting
When you want the most powerful hosting solution and you acquire any of the Linux dedicated hosting services that we are offering, you’ll be able to use the Varnish platform to optimize the work of your Internet sites at no extra charge as long as the dedicated server is ordered with our cutting-edge Hepsia hosting Control Panel. Its easy-to-work-with interface will enable you to keep track of system processes, to clear the cached content or to restart any instance with one click of the mouse. The minimal amount of system memory that the platform can employ to cache content is 3 gigabytes, which is more than enough for a huge collection of large-size sites, so your server will be able to deal with a massive system load while your site visitors are enjoying a seamless web browsing experience. As your server will come with several dedicated IP addresses, you will be able to make use of Varnish’s full capacity.
