Varnish is a website accelerator tool, which has been gaining a lot in popularity lately, as it can increase the speed of any website, at times even by one hundred 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 boost the access speed for the website visitors. Every time a visitor accesses a page on a specific website, the browser request is processed by the web server and the requested content is served as a response. If the Varnish accelerator is activated, it caches the web pages that the visitor browses and in case any of them is opened for a second time, it’s fetched by Varnish and not by the server directly. The performance improvement is due to the fact that the accelerator handles the web requests tremendously quicker than any web server, which leads to much faster browsing speeds for the visitors. In case any data is modified meanwhile, the cached pages will also be ‘refreshed’ the next time someone attempts to open them.
Varnish in Website Hosting
In case you host your websites under a website hosting
account with us, you’ll be able to add Varnish with several clicks through your hosting Control Panel. The data caching platform is available as an upgrade with all our shared web hosting plans and you can choose the number of the sites that will use it and the maximum storage space that will be available for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of memory and the number of instances and they are not linked directly to each other, so you can choose if you need plenty of memory for one single large-scale site or less memory for several smaller ones. You can take advantage of the full potential of the Varnish caching platform in case the sites use a dedicated IP. Using the Control Panel, you can easily start/reboot/discontinue an instance, delete the cached files independently for each website that uses the Varnish platform or see a detailed system log file.
Varnish in Semi-dedicated Servers
The semi-dedicated plans
that we are offering will permit you to employ Varnish once your new semi-dedicated account is active, since the caching platform is offered by default. 64 MB of system memory will be allocated to Varnish the moment your account is enabled, so you can make use of this load distribution software once your site has been published online. In case you need more system memory, you can add 32 megabytes at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated machine straight away. You can also increase the number of the websites that use Varnish, or the so-called ‘instances’, which are not directly linked to the amount of memory that you use, which suggests that you will enjoy more versatility. The caching platform will significantly decrease the load produced by your sites, so your site visitors can enjoy fast-loading pages. You’ll be able to manage the Varnish platform without efforts through the Control Panel using fast-access controls. You’ll be able to start/disable any of the instances that you have, to delete the cache associated with any of your Internet sites or to check system log files.
Varnish in VPS Servers
We provide Varnish with all of the Hepsia-managed VPS web hosting plans
, so if you buy a server with this Control Panel, you will be able to make use of the content caching platform at no extra charge. Varnish can use different amounts of memory for caching purposes depending on the very Virtual Private Server package that you have picked during the signup procedure, but in any case, this amount will not be less than several hundred MB. This is more than enough to boost the overall performance of a handful of frequently visited sites, so the better site loading speeds and the lowered load on the virtual server will be noticeable. The result may not be detectable instantly, since Varnish will require a certain amount of time to cache the website content that visitors request, but soon after you activate it, you will feel its full potential. This platform will permit you to use a lower-end server and to pay less money to get the very same performance you’d get with a more powerful virtual 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 incredibly simple-to-use graphical interface – you will be able to start, to terminate or to restart an instance, to browse an elaborate log, to delete the cached data for any Internet site and much more. The Varnish caching platform will have several gigabytes of system memory at its disposal, so even if you have busy Internet sites with plenty of visitors, you’ll notice the considerably better site load times and the lowered load on the server. This will happen shortly after you start using Varnish, since it will require some time to cache the web pages that visitors open. You can take full advantage of the platform’s capacity if the websites that are using it use also a dedicated IP address, but considering the fact that your server comes with a few IP addresses by default, you won’t have to pay anything on top of the monthly fee for the machine itself.
