Varnish is a web application accelerator platform, which caches information for the sake of quicker response times. It is sometimes called an HTTP reverse proxy as well and it interacts between a web server and a browser. When a website visitor opens a specific page, its content is requested by the Internet browser, and then the web server processes this browser request and sends back the requested data. If Varnish is enabled for a website, it will cache the pages at the first request and if the user opens a cached page once again, the information will be delivered by the caching platform instead of the web server. The boosted loading speed is a result of the considerably faster response time that the Varnish platform offers as compared to any web server software. Of course, this does not mean that the visitors will keep seeing the very same content again and again, since any modification on any of the pages is reflected in the content that the Varnish platform stores in its system memory.

Varnish in Web Hosting

Varnish is available as an optional upgrade with each Linux web hosting and if you would like to use it, you can add it to your website hosting account through the Upgrades menu in your Hepsia hosting Control Panel. There’re two separate features that can be upgraded – the number of instances and the memory. The first one depends on the number of the sites that you wish to employ Varnish for, whereas the second, which is available in increments of 32 MB, pertains to the total amount of content that the platform can store at any given moment. The Hepsia Control Panel’s simple-to-use interface will allow you to remove or to restart any instance, to see in-depth logs or to erase the platform’s cache with just one click. For best results, you can use a dedicated IP for the sites that will use the caching platform. With Varnish, your site will open substantially faster, meaning more satisfied website visitors and prospective clients.

Varnish in Semi-dedicated Servers

Varnish is an essential part of the default service set that you will obtain when you decide to host your websites under a semi-dedicated server account. You can activate it for any of your sites via our avant-garde Hepsia hosting Control Panel. The default amount of system memory that the Varnish platform can use to cache content is 64 MB, but in case you decide that you want more, you can upgrade this memory 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 simultaneously. Since these two things aren’t linked to each other, you can use a couple of sites with the default memory or you can add more memory in increments of 32 megabytes and use all of it for one single Internet site. The Varnish caching platform works best if you get a dedicated IP for the sites that utilize its power. Hepsia will provide you with a simple means of restarting any instance. In addition, you will be able to delete the cached content with only one mouse click.

Varnish in VPS Servers

We offer Varnish with all Hepsia-managed VPS web hosting plans, so in case you obtain a server with this hosting Control Panel, you’ll be able to take full advantage of the content caching platform at no additional cost. The Varnish platform can utilize different amounts of system memory for data caching purposes depending on the very package that you’ve chosen during the subscription process, but nevertheless, this amount won’t be less than several hundred megabytes. This is more than enough to improve the performance of several traffic-hungry Internet sites, so the better site load speeds and the reduced load on the virtual machine will be perceivable. The effect may not be visible right away, as the Varnish platform will require a certain amount of time to cache the website content that users browse, but soon after you activate it, you’ll feel its full potential. This caching platform will allow you to use a less powerful server and to give less money to get the exact same performance you would get with a higher-end machine without Varnish.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia Control Panel, you will obtain the Varnish platform at no additional fee and you will have full control over it through an amazingly intuitive interface – you’ll be able to start, to disable or to reboot an instance, to see an elaborate log, to clear the cache associated with any Internet site and much more. The Varnish caching platform will have several GB of memory at its disposal, so even if you’ve got traffic-hungry sites with a huge number of visitors, you’ll notice the much faster website load speeds and the lowered load on your dedicated machine. This will become a fact soon after you start using the Varnish platform, as it will require a certain amount of time to cache the content that people browse. You can take full advantage of the platform’s capability in case the Internet sites that are using it also use a dedicated IP address, but due to the fact that your dedicated server includes a couple of IP addresses by default, you won’t have to pay anything on top of your monthly fee for the server itself.
