Varnish is a web application accelerator, which has been gaining a lot in popularity in recent years, as it can increase the speed of any website, at times even by one hundred percent, depending on the content itself. This tool is sometimes referred to as an HTTP reverse proxy as well and is used to lower the overall server load and to boost the access speed for the website visitors. Whenever a visitor loads a page on a certain site, the browser request is taken care of by the web server and the requested information is sent as a response. If the Varnish accelerator is enabled, it caches the pages that the visitor opens and if any of them is accessed once more, it’s fetched by Varnish and not by the server directly. The improvement in the overall performance comes from the fact that the accelerator processes the web requests tremendously quicker than any web server, which leads to much faster browsing speeds for the website visitors. In case any content is updated meanwhile, the cached webpages will also be updated the next time someone tries to open them.
Varnish in Shared Hosting
Varnish is offered as an optional upgrade with each shared service and if you would like to use it, you can add it to your website hosting account using the Upgrades menu in your Hepsia hosting Control Panel. There are two different things that can be upgraded – the instances and the system memory. The first one refers to the number of the websites that you wish to use Varnish for and the second one, which is available in increments of 32 MB, pertains to the total amount of content that the platform can store at any given time. Hepsia’s easy-to-work-with GUI will enable you to delete or to restart any instance, to see in-depth system logs or to delete the platform’s cache with just click of the mouse. For best results, you can employ a dedicated IP for the Internet sites that will use the caching platform. With Varnish, your website will load tremendously faster, which means more satisfied site users and prospective clients.
Varnish in Semi-dedicated Servers
The Varnish content caching platform is an essential part of the default set of services that you’ll acquire if you choose to host your websites under a semi-dedicated server account. You can configure it for any of your sites via our leading-edge Hepsia hosting Control Panel. The default system memory that Varnish can use to cache content is 64 megabytes, but in case you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this platform simultaneously. Since these two features are not linked to each other, you can use a few sites with the default amount of memory or you can get more memory in increments of 32 MB and use all of it for one single site. The Varnish platform works best when you assign a dedicated IP address to the sites that utilize its power. Hepsia will provide you with a simple means of restarting any instance. What’s more, you’ll be able to clear the cached files with just a click.
Varnish in VPS Servers
The Varnish platform comes by default with each of the VPS servers offered by our company as long as the virtual machine is ordered with the Hepsia Control Panel, so you can improve the work of your sites with just a couple of clicks of the mouse. The more powerful the plan, the more system memory Varnish will have at its disposal, but even with a lower-end plan, the platform will be able to utilize several hundred MB, so even if you manage a handful of websites, you will notice a great decrease in the server load and a substantially better webpage load speed. The platform will need to work for a little while as the users browse the site and once the content has been cached, you’ll see the result. One of the benefits of using Varnish is that a less powerful and less pricey Virtual Private Server plan will accomplish the same job as a more costly one without the caching platform, so not only will your Internet sites perform substantially better, but you will also save some cash.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish data caching platform at no extra charge and you will exert total control over it through a truly easy-to-work-with GUI – you will be able to start, to delete or to reboot an instance, to see an exhaustive log, to delete the cached data associated with any Internet site and much more. The Varnish platform will have several gigabytes of memory at its disposal, so even if you run resource-consuming sites with a lot of visitors, you’ll notice the considerably faster website loading times and the decreased load on your dedicated machine. This will happen soon after you begin using Varnish, since it will need a certain amount of time to cache the pages that users browse. You can take full advantage of the platform’s capability if the websites that are using it use also a dedicated IP, but considering the fact that your dedicated server comes with a couple of IPs by default, you will not have to pay anything on top of the monthly fee for the server itself.
