Varnish is a website accelerator platform, which caches data for the sake of quicker response times. It is sometimes called a caching HTTP reverse proxy as well and it interacts between a web server and its users. When a visitor opens a specific webpage, the content is requested by the web browser, and then the web server processes this request and sends back the requested info. If Varnish is enabled for a specific website, it will cache the pages at the very first request and if the user visits a cached page once more, the information will be delivered by the accelerator platform and not by the web server. The increased speed is a result of the significantly faster response speed that Varnish offers as compared with any web server software. At the same time, this doesn’t mean that the site visitors will continue seeing the same content again and again, since any update on any of the web pages is reflected in the content that the Varnish platform saves in its memory.
Varnish in Shared Hosting
Varnish is available as an optional upgrade with each and every Linux shared hosting and if you’d like to use it, you can add it to your hosting account using the Upgrades menu in your Hepsia Control Panel. There are two different features that can be upgraded – the instances and the memory. The first one depends on the number of the websites that you would like to use Varnish for, whereas the second, which comes in increments of 32 MB, pertains to the total amount of data that the data caching platform can cache at any particular moment. Hepsia’s easy-to-work-with graphical interface will enable you to disable or to restart any instance, to check detailed system logs or to delete the platform’s cache with just click of the mouse. For maximum results, you can use a dedicated IP for the websites that will use the caching platform. With Varnish, your site will load substantially faster, which means more satisfied website visitors and potential customers.
Varnish in Semi-dedicated Hosting
The Varnish data caching platform is an essential part of the basic set of services that you’ll get if you choose to host your Internet sites under a semi-dedicated server account. You can configure it for any of your websites through our advanced Hepsia Control Panel. The default amount of memory that the Varnish caching platform can use to cache content is 64 MB, but in case you decide that you need more, you can upgrade this amount from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this platform simultaneously. Since these two things are not linked to each other, you can use a few sites with the default memory or you can get more memory in increments of 32 MB and use all of it for a single site. The Varnish caching platform works best when you assign a dedicated IP to the websites that utilize its power. Hepsia will provide you with an easy way of rebooting any instance. Also, you will be able to clear the cached files with just a click.
Varnish in VPS
The Varnish caching platform comes by default with each of the Linux VPS offered by us given that the machine is ordered with the Hepsia hosting Control Panel, so you can improve the overall performance of your sites with only a few clicks of the mouse. The more powerful the package, the more memory Varnish will have at its disposal, but even with a lower-end package, the caching platform will be able to utilize several hundred megabytes, so even if you run several Internet sites, you will notice an enormous decrease in the server load and a considerably faster page load speed. The platform will need to work for a while while the visitors browse the site and once the content has been cached, you will notice the results. One of the upsides of employing Varnish is that a less powerful and less costly Virtual Private Server plan will accomplish the exact same job as a more pricey one without the platform, so not only will your websites perform substantially better, but you’ll also save a certain amount of cash.
Varnish in Dedicated Hosting
If you order a dedicated server with the Hepsia hosting Control Panel, you’ll obtain the Varnish caching platform at no extra charge and you’ll exert full control over it through a rather user-friendly GUI – you will be able to start, to delete or to restart an instance, to check an in-depth system log, to delete the cached data for any website and much more. The Varnish caching platform will have several gigabytes of virtual memory at its disposal, so even if you’ve got resource-consuming websites with an immense number of visitors, you will notice the much better site loading times and the decreased load on your dedicated server. This will happen shortly after you start using Varnish, since it will require some time to cache the pages that people request. You can get the most out of the platform’s capacity in case the websites that are using it also use a dedicated IP, but since your dedicated server includes several IPs by default, you will not need to pay anything on top of your monthly charge for the server itself.
