Varnish is a website accelerator platform, which caches content for the sake of faster response times. It’s occasionally referred to as an HTTP reverse proxy too and it interacts between a web server and a browser. When a website visitor opens a given page, its content is requested by the Internet browser, and then the web server processes this request and sends back the necessary info. If Varnish is activated for a specific website, it will cache the pages on the very first request and in case the visitor visits a cached page for a second time, the content will be delivered by the accelerator platform and not by the web server. The accelerated speed is a result of the significantly faster response speed that the Varnish platform offers as compared with any server software. Of course, this doesn’t mean that the visitors will keep being served the same content again and again, since any update on any of the pages is reflected in the content that Varnish keeps in its memory.
Varnish in Shared Website Hosting
You can unlock Varnish’s potential and improve the speed of your websites regardless of the shared website hosting package that you have selected and you can enable and configure the data caching platform with a few mouse clicks using the easy-to-work-with interface offered by our next-generation Hepsia Control Panel. During the procedure, you’ll be able to select two separate things – how many websites will employ Varnish, i.e. the number of instances, and how much information will be cached, i.e. the amount of memory. The latter is available in increments of 32 megabytes and is not bound to the number of instances, so you can use more instances and less memory and the other way around. If you have lots of content on a particular Internet site and you win plenty of site visitors, more memory will give you better results. You may also consider using a dedicated IP for the sites that will use the Varnish platform. The Hepsia Control Panel will provide you with easy 1-click buttons for stopping or restarting any instance, for deleting the cache associated with any site and for checking in-depth logs.
Varnish in Semi-dedicated Servers
The Varnish caching platform is part of the standard service set that you will acquire when you decide to host your Internet sites in a semi-dedicated server account. You can set it up for any of your websites via our avant-garde Hepsia Control Panel. The default amount of system memory that the Varnish caching platform can use to cache data is 64 megabytes, 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 Internet sites that can use this caching platform at the same time. Since these two features are not bound to each other, you can use a couple of sites with the default amount of memory or you can order more memory in increments of 32 MB and use all of it for a single website. Varnish performs best if you assign a dedicated IP address to the Internet sites that utilize its power. Hepsia will give you a simple way of restarting any instance. On top of that, you will be able to clear the cached files with just a click.
Varnish in VPS Servers
The Varnish content caching platform is included by default with each of the Linux VPS hosting service offered by us on the condition that the Virtual Private Server is ordered with the Hepsia Control Panel, so you can optimize the performance of your sites with only a couple of clicks of the mouse. The more powerful the package, the more memory will be available to Varnish, but even with a lower-end plan, the caching platform will be able to utilize several hundred megabytes, so even if you manage a handful of Internet sites, you will notice a considerable reduction in the server load and a tremendously faster website load speed. The platform will need to work for a little while as the users navigate the site and once the content has been cached, you’ll perceive the results. One of the upsides of using Varnish is that a lower-end and less costly VPS plan will accomplish the exact same job as a more high-priced one without the caching platform, so not only will your Internet sites perform better, but you will also spare a certain amount of cash.
Varnish in Dedicated Servers
You can employ Varnish to enhance the loading speed of any site that is hosted on a dedicated server with us when the Hepsia hosting Control Panel is pre-installed on the machine. Not only will you get the caching platform ready for use at no extra cost, but you will also exert total control over it via the Hepsia Control Panel’s user-friendly interface. It’ll take just one click to start or delete an instance or to delete the cached data for any Internet site that’s using Varnish and in case you are more trained, you can also view the platform’s logs. Varnish comes with no less than 3 gigabytes of virtual memory for web content caching purposes, so even if you run a vast number of Internet sites on your dedicated server and they all use the Varnish platform, the difference in their overall performance will be obvious. You will only have to wait for a while until Varnish caches whatever web pages the site visitors load on their end. The Varnish platform works best when the sites use a dedicated IP address, but owing to the fact that our servers include 3 free-of-charge IPs, you will have everything you need.
