Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, as it can increase the speed of any Internet site, at times even by 100%, based on the content. This tool is occasionally called a caching HTTP reverse proxy too and is used to decrease the overall load on the physical machine and to accelerate the access speed for the website visitors. Each time a visitor opens a page on a certain Internet site, the browser request is taken care of by the web server and the requested content is delivered as a reply. If the Varnish accelerator is activated, it caches the web pages that the website visitor browses and in case any of them is loaded for a second time, it is fetched by Varnish and not by the server directly. The performance increase comes from the fact that the accelerator handles the web requests tremendously faster than any web server, which leads to much faster browsing speeds for the website visitors. If any content is modified in the meantime, the cached web pages will also be ‘refreshed’ the next time somebody opens them.

Varnish in Web Hosting

Varnish is available as an optional upgrade with each Linux web hosting and if you want to use it, you can add it to your account using the Upgrades section in your Hepsia hosting Control Panel. There’re two different features that can be upgraded – the number of instances and the memory. The first one depends on the number of the Internet sites that you want to use Varnish for, whereas the second, which is offered in increments of 32 megabytes, pertains to the total amount of data that the data caching platform can store at any given moment. Hepsia’s simple-to-use interface will allow you to stop or to reboot any instance, to check comprehensive logs or to clear the platform’s cache with just click of the mouse. For optimum results, you can employ a dedicated IP for the Internet sites that will use the platform. With Varnish, your site will open significantly faster, meaning more satisfied site users and potential clients.

Varnish in Semi-dedicated Hosting

Varnish comes as standard with all Linux semi-dedicated hosting offered by us and you can use it for load distribution purposes. It is available in your Hepsia hosting Control Panel. The caching platform comes with 64 megabytes of system memory for cached data storing purposes and you can employ it with any Internet site that you host in the account. In case you need more, you can increase the memory allocation. The memory itself is available in increments of 32 megabytes in the Upgrades section of the Control Panel. The same Upgrades section will permit you to create more instances too, in case you wish to use the Varnish caching platform with multiple sites. The two upgrades can be added independently – you can cache the content of one popular site or run several different sites with the default memory quota. You can take full advantage of the Varnish platform if you have a dedicated IP address and you can order one with your semi-dedicated plan as well. Hepsia will give you full control over the caching platform and, with no more than one mouse click, you’ll be able to clear the cached files, to see a system log or to restart an instance.

Varnish in VPS Hosting

The Varnish data caching platform comes by default with each of the Linux VPS hosting that we offer on the condition that the virtual server is ordered with the Hepsia Control Panel, so you can enhance the work of your websites with only a few clicks of the mouse. The more powerful the plan, the more memory will be available to Varnish, but even with a less powerful package, the caching platform will be able to utilize several hundred MB, so even if you run a number of sites, you will notice a noticeable decrease in the server load and a substantially faster webpage load speed. The Varnish platform will need to work for a little while as the users navigate the site and once the site content has been cached, you’ll see the result. One of the pros of using Varnish is that a less powerful and less expensive plan will accomplish the very same job as a more pricey one without the platform, so not only will your Internet sites work significantly better, but you’ll also spare a certain amount of cash.

Varnish in Dedicated Web Hosting

You can use Varnish in order to optimize the speed of any website that’s hosted on a dedicated server from our company if the Hepsia Control Panel is pre-installed on it. Not only will you get the platform ready to be used at no extra cost, but you’ll also exert complete control over it through the Hepsia Control Panel’s easy-to-work-with graphical interface. It will take just one single click to start or cancel an instance or to clear the cache associated with any website that is using the Varnish platform and if you are more experienced, you can also check the platform’s system logs. Varnish comes with at least 3 GB of memory for website content caching purposes, so even if you host lots of websites on your dedicated machine and they all use the caching platform, the improvement in their performance will be observable. You’ll just have to wait for a while till Varnish caches whatever webpages the website visitors browse on their end. The Varnish platform works best when the sites use a dedicated IP address, but due to the fact that our servers include three free IPs, you will have everything you need.
