Varnish is a web application accelerator, which has been gaining a lot in popularity in recent years, as it can increase the speed of any site, at times even by 100 percent, depending on the content. This tool is sometimes referred to as an HTTP reverse proxy as well and is used to lower the overall load on the physical machine and to accelerate the access speed for the website visitors. Each time a visitor accesses a page on a particular website, the web browser request is handled by the web server and the requested info is delivered as a reply. If the Varnish accelerator is enabled, it caches the web pages that the visitor browses and in case any of them is accessed again, it is fetched by Varnish and not by the server directly. The improvement in the overall performance comes from the fact that the accelerator processes the browser requests considerably faster than any web server, which leads to much faster browsing speeds for the users. If any content is edited meanwhile, the cached webpages will also be updated the next time someone tries to open them.
Varnish in Cloud Hosting
In case you host your websites in a cloud hosting account with our company, you’ll be able to activate Varnish with several clicks of the mouse via your hosting Control Panel. The caching platform is available as an upgrade with all our shared hosting plans and you can select how many websites will use it and the maximum amount of system memory that will be used for the cached data. 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 directly tied to each other, so you can decide whether you want a lot of memory for one single large-scale site or less memory for multiple smaller ones. You can take advantage of the full potential of Varnish in case the websites use a dedicated IP. Using the hosting Control Panel, you can quickly start/reboot/stop an instance, delete the cached contents individually for each site that employs Varnish or see an elaborate log file.
Varnish in Semi-dedicated Hosting
Varnish is included in the basic set of services that you’ll get in case you decide to host your Internet sites under a semi-dedicated server account. You can enable it for any of your sites through our advanced Hepsia hosting Control Panel. The default amount of memory that Varnish can use to cache data is 64 MB, 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 caching platform at the same time. Since these two features aren’t bound to each other, you can use a few websites with the default amount of memory or you can order more memory in increments of 32 MB and use all of it for one single site. The Varnish platform performs best when you get a dedicated IP for the sites that utilize its power. The Hepsia Control Panel will offer you a simple way of rebooting any instance. In addition, you will be able to delete the cached data with only one click of the mouse.
Varnish in VPS Web Hosting
You can take advantage of Varnish with all our virtual private server packages at no additional fee, since the platform is pre-installed and is included by default. The sole condition is that the VPS must come with the Hepsia Control Panel, via which you’ll be able to set up Varnish for any of your sites with only a couple of clicks of the mouse. Each plan includes a different amount of memory for data caching purposes, but you’ll get no less than several hundred megabytes, which is enough even for several traffic-intensive websites. Shortly after you activate Varnish, it’ll begin caching the content that your site visitors open, so you’ll notice the substantially faster web page load times and the decreased load on the VPS in no time. The Varnish caching platform will permit you to use a less pricey virtual machine, as you will not require that much power to guarantee the correct operation of your websites even if you run traffic-heavy sites with lots of visitors. Best results are accomplished if the Internet sites that use the Varnish caching platform use also a dedicated IP.
