Varnish is a web application accelerator tool, which has been gaining a lot of popularity lately, as it can increase the load speed of any Internet site, at times even by one hundred percent, based on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to reduce the overall load on the physical server and to increase the access speed for the site visitors. Whenever a visitor loads a page on a given Internet site, the web browser request is processed by the web server and the requested info is served as a reply. If the Varnish accelerator is activated, it caches the web pages that the website visitor opens and if any of them is loaded once again, it’s served by Varnish and not by the server directly. The increase in the performance comes from the fact that the accelerator handles the browser requests significantly faster than any web server, which leads to much faster browsing speeds for the visitors. If any data is modified in the meantime, the cached pages will also be updated the next time somebody tries to access them.

Varnish in Website Hosting

If you host your websites in a website hosting account with our company, you’ll be able to activate Varnish with a couple of mouse clicks from your Control Panel. The content caching platform comes as an upgrade with all our web hosting packages and you can choose how many sites will use it and the total storage space that will be used for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they aren’t directly linked to each other, so you can choose whether you need plenty of memory for one large-size site or less memory for several smaller ones. You can make use of the full potential of the Varnish caching platform if the sites use a dedicated IP address. With the hosting Control Panel, you can swiftly start/reboot/disable an instance, delete the cached files individually for each site that employs the Varnish platform or see a detailed log.

Varnish in Semi-dedicated Servers

Varnish is a feature, which is included by default with all semi-dedicated servers that we are offering and you can use it for load balancing purposes. It is available in your Hepsia hosting Control Panel. The content caching platform comes with 64 MB of system memory for cached data storing purposes and you can use it with any site that you host in your account. In case you are in need of more, you can increase the system memory allocation. The memory itself is available in increments of 32 megabytes in the Upgrades section of the Control Panel. The exact same section will allow you to create more instances too, if you would like to use the Varnish platform with more websites. The two things can be added independently – you can cache the content of one single traffic-hungry website or use several different Internet sites with the default memory. You can get the most out of the Varnish caching platform if you have a dedicated IP and you can order one with your semi-dedicated plan as well. Hepsia will grant you total control over the platform and, with no more than one single mouse click, you’ll be able to clear the cached contents, to see a system log or to reboot an instance.

Varnish in VPS Servers

We provide Varnish with all of the Hepsia-managed VPS servers, so if you obtain a VPS with this Control Panel, you’ll be able to make full use of the data caching platform at no additional fee. Varnish can use different amounts of memory for content caching purposes depending on the specific configuration that you have picked during the subscription process, but in any case, this amount won’t be less than several hundred megabytes. This is quite enough to enhance the overall performance of a handful of resource-heavy sites, so the faster web page loading speeds and the lowered load on the virtual machine will be noticeable. The effect may not be evident straight away, as Varnish will require some time to cache the website content that people browse, but soon 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 pay less money to get the same performance you would get with a higher-end virtual machine without Varnish.

Varnish in Dedicated Servers

All dedicated servers which are ordered with the in-house built Hepsia website hosting Control Panel include Varnish, which is among the pre-installed software platforms that you will get with the server. The Varnish content caching platform can be configured and administered without efforts from the Hepsia Control Panel’s simple-to-use graphical interface and, with no more than one click of the mouse, you can view a detailed log, create or reboot an instance, delete the cache for any website and much, much more. Soon after you set up the Varnish platform for a particular domain or sub-domain, it will start caching the webpages opened by the website visitors and once it has cached enough web content, you’ll observe a significantly faster site performance as well as a decreased server load. With Varnish-dedicated memory starting at 3 gigabytes, you will be able to use the software platform for load balancing purposes even if you host a vast number of sites on the dedicated machine.
