Varnish is a web application accelerator tool, which has been gaining a lot in popularity in recent years, because it can increase the loading speed of any Internet site, sometimes even by 100%, depending on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy as well and is used to decrease the overall load on the physical server and to boost the access speed for the website visitors. Each time a visitor opens a page on a given site, the web browser request is taken care of by the web server and the requested content is sent as a reply. If Varnish is enabled, it caches the web pages that the site visitor opens and in case any of them is loaded again, it’s fetched by Varnish and not by the web server directly. The performance boost is due to the fact that the accelerator handles the browser requests considerably faster than any web server, which leads to much faster browsing speeds for the visitors. If any data is modified meanwhile, the cached pages will also be ‘refreshed’ the next time somebody tries to open 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 mouse clicks via your Control Panel. The data caching platform comes as an optional upgrade with all our web hosting plans and you can select how many websites will use it and the total storage space that will be available for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they’re not linked directly to each other, so you can choose if you want a lot of memory for a single large-sized website or less memory for multiple smaller ones. You can take advantage of the full potential of Varnish if the sites use a dedicated IP address. Using the Control Panel, you can effortlessly start/reboot/delete an instance, delete the cached content independently for each site which employs Varnish or view an exhaustive system log file.
Varnish in Semi-dedicated Hosting
The Varnish platform is an essential part of the default set of services that you will get if you choose to host your sites under a semi-dedicated server account. You can set it up for any of your Internet sites via our next-gen Hepsia hosting Control Panel. The default amount of system memory that the Varnish caching platform can use to cache content is 64 MB, but if you decide that you want more, you can upgrade this amount of memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this platform simultaneously. As these two things are not bound to each other, you can use a few websites with the default memory or you can get more memory in increments of 32 MB and use all of it for a single site. Varnish performs best if you get a dedicated IP for the websites that utilize its power. The Hepsia Control Panel will offer you an easy way of rebooting any instance. In addition, you’ll be able to clear the cached content with just one click.
Varnish in VPS Web Hosting
We offer Varnish with all Hepsia-equipped VPS web hosting, so in case you acquire a server with this web hosting Control Panel, you will be able to make the most of the content caching platform at no additional cost. The Varnish platform can use different amounts of system memory for caching purposes based on the particular configuration that you have chosen during the signup procedure, but in any case, this amount won’t be less than several hundred MB. This is more than enough to boost the performance of a number of resource-absorbing Internet sites, so the faster website browsing speeds and the reduced load on the machine will be perceptible. The effect may not be distinguishable immediately, as Varnish will need some time to cache the website content that visitors request, but shortly after you set it up, you’ll perceive its full potential. This caching platform will allow you to use a lower-end VPS and to give less cash to get the exact same performance you’d get with a higher-end virtual machine without Varnish.
Varnish in Dedicated Servers Hosting
All Linux dedicated servers hosting that are ordered with the tailor-made Hepsia hosting Control Panel come with Varnish, which is one of the pre-installed software platforms that you will get with the dedicated machine. The Varnish data caching platform can be enabled and administered with ease from Hepsia’s easy-to-use GUI and, with no more than a click, you can see an exhaustive log, add or reboot an instance, clear the cache associated with any Internet site and much, much more. Soon after you configure Varnish for a given domain or subdomain, it will begin caching the webpages requested by your website visitors and once it has cached enough web content, you will observe a substantially better website performance and a lowered load on your dedicated machine. With Varnish-dedicated virtual memory starting at 3 GB, you will be able to use the software platform for load distribution purposes even if you host a huge number of websites on your dedicated server.
