Varnish is a website accelerator platform, which caches info for faster response times. It is occasionally called an HTTP reverse proxy too and it interacts between a web server and its users. When a visitor opens a particular webpage, its content is requested by the web browser, and then the web server processes this browser request and returns the requested content. If Varnish is enabled for a website, it will cache the pages at the first visit and if the visitor visits a cached page for a second time, the info will be delivered by the caching platform instead of the server. The improved loading speed is an end result of the considerably faster response speed that Varnish offers as compared with any server software. At the same time, this doesn’t mean that the site visitors will keep seeing the same content over and over again, since any update on any of the pages is reflected in the content that Varnish stores in its memory.
Varnish in Cloud Web Hosting
Our company offers Varnish as an optional upgrade with each Linux cloud web hosting service and if you wish to use it, you can add it to your website hosting account via the Upgrades section in your Hepsia Control Panel. There’re two different things that can be upgraded – the number of instances and the memory. The first one refers to the number of the websites that you wish to use Varnish for and the second one, which comes in increments of 32 megabytes, refers to the maximum amount of content that the platform can cache at any given time. Hepsia’s intuitive GUI will permit you to turn off or to reboot any instance, to check in-depth system logs or to get rid of the platform’s cache with just click of the mouse. For best results, you can use a dedicated IP address for the sites that will use the caching platform. With Varnish, your website will open substantially faster, meaning more pleased visitors and potential clients.
Varnish in Semi-dedicated Servers
The Varnish content caching platform is included in the basic set of services that you will acquire if you decide to host your Internet sites under a semi-dedicated server account. You can activate it for any of your websites via our avant-garde Hepsia Control Panel. The default memory that the Varnish platform can use to cache content is 64 MB, but in case you decide that you want more, you can upgrade this amount from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this platform at the same time. Since these two features aren’t tied to each other, you can use a couple of instances with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for a single site. The Varnish caching platform works best when you use a dedicated IP for the Internet sites that utilize its power. Hepsia will provide you with an easy way of rebooting any instance. Also, you’ll be able to clear the cached files with only one mouse click.
Varnish in VPS Servers
We provide Varnish with all of the Hepsia-equipped Linux VPS servers, so if you purchase a VPS with this Control Panel, you’ll be able to make the most of the content caching platform at no extra fee. Varnish can utilize different amounts of memory for data caching purposes based on the specific VPS plan that you’ve selected during the subscription process, but at any rate, this amount won’t be less than several hundred MB. This is more than enough to optimize the performance of several large-scale Internet sites, so the faster website browsing speeds and the decreased load on your virtual server will be discernible. The effect may not be observable immediately, since Varnish will need a certain amount of time to cache the website content that visitors open, but soon after you set it up, you will perceive its full potential. This caching platform will permit you to use a lower-end server and to pay less cash to get the exact same performance you’d get with a higher-end virtual machine without Varnish.
Varnish in Dedicated Servers
All dedicated service that are ordered with the custom Hepsia website hosting Control Panel come with Varnish, which is one of the pre-installed platforms that you’ll get with the server. The Varnish data caching platform can be activated and managed effortlessly via the Hepsia Control Panel’s easy-to-work-with graphical interface and, with no more than one click of the mouse, you can see a comprehensive system log, add or restart an instance, delete the cached files for any Internet site and much more. Soon after you set up Varnish for a specific domain or sub-domain, it will begin caching the web pages loaded by the site visitors and as soon as it has cached enough content, you will witness a significantly faster site performance as well as a decreased load on the dedicated server. With Varnish-dedicated system memory starting at 3 GB, you’ll be able to use the software platform for load balancing purposes even if you host an immense number of sites on the machine.
