Varnish is a web application accelerator, which has been gaining a lot in popularity lately, as it can increase the load speed of any site, at times even by 100 percent, depending on the content itself. This tool is sometimes called a caching HTTP reverse proxy as well and is used to decrease the overall load on the server and to improve the access speed for the website visitors. Each time a visitor loads a page on a specific Internet site, the web browser request is processed by the web server and the requested information is sent as a response. If Varnish is activated, it caches the pages that the site visitor opens and in case any of them is opened for a second time, it’s served by Varnish and not by the web server directly. The increase in the performance is due to the fact that the accelerator handles the browser requests significantly quicker than any web server, which leads to much faster browsing speeds for the visitors. If any data is changed meanwhile, the cached web pages will also be ‘refreshed’ the next time someone opens them.

Varnish in Cloud Web Hosting

In case you host your sites in a cloud web hosting account with us, you will be able to activate Varnish with a few clicks of the mouse from your Control Panel. The content caching platform is offered as an optional upgrade with all our plans and you can choose how many sites will use it and the maximum storage space that will be available for the cached content. The two features that can be upgraded in the Upgrades section of the Control Panel are the number of instances and the amount of memory and they are not tied directly to each other, so you can decide whether you want plenty of memory for a single large-size site or less memory for several smaller ones. You can make use of the full potential of the Varnish platform if the websites use a dedicated IP. With the Control Panel, you can easily start/restart/stop an instance, clear the cached data independently for each site that uses Varnish or check an exhaustive log.

Varnish in Semi-dedicated Servers

The Varnish platform is an essential part of the standard service set that you’ll receive if you decide to host your sites under a semi-dedicated server account. You can activate it for any of your websites through our cutting-edge Hepsia hosting Control Panel. The default memory that the Varnish platform can use to cache content is 64 megabytes, but if you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this platform simultaneously. As these two features aren’t linked to each other, you can use a couple of sites with the default memory or you can get more memory in increments of 32 megabytes and use all of it for one single website. The Varnish platform works best if you assign a dedicated IP address to the Internet sites that utilize its power. The Hepsia Control Panel will give you a simple means of restarting any instance. What’s more, you will be able to clear the cached files with only one single click of the mouse.

Varnish in VPS Servers

The Varnish platform is included by default with all VPS servers that we offer given that the Virtual Private Server is ordered with the Hepsia Control Panel, so you can enhance the performance of your websites with only a few clicks. The more powerful the plan, the more memory Varnish will have at its disposal, but even with a lower-end plan, the caching platform will be able to utilize several hundred megabytes, so even if you manage a handful of websites, you’ll notice an immense reduction in the server load and a tremendously better site loading speed. The Varnish caching platform will need to work for a while while the visitors navigate the web pages and as soon as the site content has been cached, you’ll perceive the effects. One of the advantages of using Varnish is that a lower-end and less pricey Virtual Private Server plan will accomplish the exact same job as a more costly one without the platform, so not only will your websites perform significantly better, but you’ll also spare some cash.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you will obtain the Varnish content caching platform at no extra fee and you will exert total control over it through an extremely easy-to-use interface – you will be able to start, to disable or to restart an instance, to view an in-depth system log, to clear the cache associated with any Internet site and much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you own traffic-hungry Internet sites with a lot of visitors, you’ll notice the considerably better website load speeds and the lowered load on your dedicated server. This will become a fact soon after you begin using Varnish, as it will require a certain amount of time to cache the web pages that visitors access. You can get the most out of the platform’s potential if the Internet sites that are using it also use a dedicated IP address, but considering the fact that your server comes with a few IP addresses by default, you will not need to pay anything on top of your monthly charge for the server itself.
