Varnish is a web accelerator platform, which caches info for quicker response times. It is sometimes called an HTTP reverse proxy as well and it works between a web server and a web browser. When a website visitor accesses a specific webpage, its content is requested by the Internet browser, and then the server handles this browser request and returns the requested data. If Varnish is enabled for a specific site, it will cache its pages at the very first request and in case the visitor visits a cached page once more, the info will be delivered by the caching platform and not by the server. The improved speed is a result of the considerably faster response time that the Varnish platform offers compared with any server software. Of course, this doesn’t mean that the visitors will continue being served the exact same content again and again, as any change on any of the pages is reflected in the content that the Varnish platform stores in its memory.
Varnish in Hosting
Varnish comes as an optional upgrade with each Linux hosting and if you want to use it, you can add it to your website hosting account using the Upgrades section in your Hepsia Control Panel. There are two separate features that can be upgraded – the instances and the memory. The first one pertains to the number of the websites that you would like to use Varnish for and the second one, which is offered in increments of 32 MB, refers to the total amount of content that the content caching platform can store at any particular moment. The Hepsia Control Panel’s time and effort saving interface will permit you to switch off or to reboot any instance, to view exhaustive system logs or to delete the platform’s cache with just a click. For optimal results, you can use a dedicated IP for the Internet sites that will use the caching platform. With Varnish, your site will open tremendously faster, meaning more pleased site visitors and potential customers.
Varnish in Semi-dedicated Hosting
Varnish is offered by default with all semi-dedicated hosting offered by us and you can use it for workload balancing purposes. It’s available in your Hepsia Control Panel. The Varnish caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can use it with any website that you host in the account. If you need more, you can increase the memory allowance. The memory itself is available in increments of 32 megabytes through the Control Panel’s Upgrades section. The same Upgrades section will enable you to enable more instances as well, in case you wish to use Varnish with more sites. The two upgrades can be added independently – you can cache the content of a single large website or use several websites with the default memory allocation. You can take full advantage of the Varnish platform in case you have a dedicated IP address and you can order one with your semi-dedicated package as well. Hepsia will give you complete control over the caching platform and, with no more than one single click, you will be able to clear the cache, to check a log file or to restart an instance.
Varnish in VPS
You can take full advantage of the workload balancing potential of Varnish with any of our VPS when you select Hepsia as your web hosting Control Panel. The content caching platform comes by default and the memory that it will be able to use to cache the content of your sites depends on the specific VPS package that you have selected, but even with the less powerful packages, you will have no less than several hundred megabytes of system memory at your disposal exclusively for caching purposes. This amount is sufficient to improve the work of numerous websites. It will take a little time for you to detect the effects, since Varnish caches the content that site visitors request, but shortly thereafter you will notice the substantially less load on the machine and the enhanced site loading speed. Varnish will allow you to use a less powerful VPS plan for sites which would normally need a more expensive web hosting service.
Varnish in Dedicated Hosting
If you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish platform at no additional cost and you’ll exert full control over it through a pretty simple-to-work-with interface – you will be able to start, to terminate or to reboot an instance, to check an elaborate system log, to clear the cached content for any Internet site and much more. The Varnish caching platform will have several gigabytes of virtual memory at its disposal, so even if you manage large-sized sites with a vast number of visitors, you’ll notice the tremendously better site loading speeds and the less load on your dedicated machine. This will happen soon after you begin using the Varnish platform, as it will require a certain amount of time to cache the web pages that visitors access. You can take full advantage of the platform’s capability in case the websites that are using it use also a dedicated IP, but owing to the fact that your server includes a few IP addresses by default, you will not need to pay anything on top of your monthly charge for the machine itself.
