Varnish is a content caching platform, which is occasionally called an HTTP reverse proxy. It is a website accelerator that can improve the speed of a site by up to 1000%, depending on its content. Each time a visitor opens any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server if the visitor opens it again. Thus, the web browser request from the visitor is not handled by the server and the web page will load considerably faster, since the Varnish caching platform can serve data many times faster than any server software. The end result is a substantially faster loading website, which leads to an enormously improved website browsing experience. When any of the cached web pages is updated on the live Internet site, the information that Varnish stores in its memory is ‘refreshed’ as well, so the website visitors will never end up seeing old information.
Varnish in Shared Website Hosting
You can unlock Varnish’s potential and accelerate the load speed of your sites regardless of the shared website hosting package that you have picked and you can activate and configure the data caching platform with a few clicks of the mouse using the intuitive interface offered by our leading-edge Hepsia Control Panel. During the procedure, you will be able to choose two separate things – how many websites will employ the Varnish platform, i.e. the number of instances, and how much information will be cached, in other words – the amount of memory. The latter is offered in increments of 32 megabytes and is not bound to the number of instances, so you can add more instances and less memory and vice versa. In case you have a lot of content on a particular Internet site and you attract plenty of website visitors, more system memory will give you better results. You may also consider using a dedicated IP address for the websites that will use the Varnish caching platform. Hepsia will offer you simple 1-click buttons for removing or restarting any instance, for deleting the cache for any website and for seeing comprehensive logs.
Varnish in Semi-dedicated Hosting
The Varnish platform is an essential part of the default service set that you’ll receive in case you choose to host your sites in a semi-dedicated server account. You can configure it for any of your sites via our cutting-edge Hepsia Control Panel. The default 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 memory from the Control Panel’s Upgrades section. 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. As these two features are not linked to each other, you can use a few Internet sites with the default memory or you can add more memory in increments of 32 MB and use all of it for a single website. Varnish performs best when you allocate a dedicated IP address to the websites that utilize its power. Hepsia will offer you an easy means of restarting any instance. On top of that, you will be able to delete the cached content with just a click.
Varnish in VPS
Varnish is included by default with all Linux VPS packages that we’re offering on the condition that the Virtual Private Server is ordered with the Hepsia hosting Control Panel, so you can optimize the work of your websites with just a couple of clicks. The more powerful the package, the more system memory Varnish will have at its disposal, but even with a low-end plan, the platform will be able to utilize several hundred MB, so even if you own a handful of sites, you will notice a noticeable decrease in the overall server load and a considerably better web page load speed. The Varnish caching platform will need to work for a while as the users navigate the web pages and as soon as the website content has been cached, you’ll perceive the results. One of the advantages of employing Varnish is that a lower-end and less expensive VPS plan will do the very same job as a more expensive one without the caching platform, so not only will your sites perform better, but you’ll also spare a certain amount of money.
Varnish in Dedicated Hosting
In case you order a dedicated server with the Hepsia Control Panel, you will get the Varnish caching platform at no additional cost and you’ll exert full control over it via an amazingly intuitive graphical interface – you will be able to start, to stop or to reboot an instance, to check a detailed system log, to delete the cached content for any site and much, much more. The Varnish caching platform will have several gigabytes of system memory at its disposal, so even if you own resource-hungry Internet sites with multiple visitors, you will notice the much better page load speeds and the decreased load on the machine. This will happen shortly after you start using the Varnish platform, as it will require a certain amount of time to cache the site content that users access. You can get the most out of the platform’s capability if the sites that are using it also use a dedicated IP, but owing to the fact that your dedicated server comes with a few IPs by default, you won’t have to pay anything on top of the monthly fee for the machine itself.
