Varnish is a web accelerator platform, which caches content for the sake of quicker response times. It’s sometimes referred to as a caching HTTP reverse proxy as well and it works between a web server and its users. When a website visitor accesses a certain web page, the content is requested by the browser, and then the web server handles this request and delivers the needed information. If Varnish is activated for a particular website, it will cache the pages at the very first visit and if the user accesses a cached page once again, the info will be delivered by the caching platform instead of the server. The improved speed is a result of the significantly faster response time that the Varnish platform offers compared with any web server software. At the same time, this does not mean that the website visitors will continue being served the exact same content again and again, because any change on any of the web pages is reflected in the content that Varnish saves in its memory.
Varnish in Cloud Web Hosting
Varnish is offered as an optional upgrade with each and every Linux cloud web hosting and if you wish to use it, you can add it to your hosting account through the Upgrades menu in your Hepsia Control Panel. There’re two separate features that can be upgraded – the number of instances and the memory. The first one depends on the number of the Internet sites that you wish to use Varnish for, whereas the second, which is offered in increments of 32 MB, refers to the total amount of content that the content caching platform can cache at any given moment. Hepsia’s intuitive interface will permit you to shut down or to restart any instance, to see detailed system logs or to get rid of the platform’s cache with just one click. For optimum results, you can employ a dedicated IP for the Internet sites that will use the caching platform. With Varnish, your Internet site will open tremendously faster, meaning more satisfied site visitors and prospective customers.
Varnish in Semi-dedicated Servers
Varnish is included by default with all Linux semi-dedicated plans offered by our company and you can use it for workload balancing purposes. It is available in your Hepsia hosting Control Panel. The platform comes with 64 MB of system memory for cached data storing purposes and you can employ it with any website that you host in your account. In case you are in need of more than that, you can increase the system memory allocation. The memory itself is available in increments of 32 MB in the Upgrades section of the Control Panel. The exact same section will enable you to enable more instances as well, if you’d like to use Varnish with multiple sites. The two things can be ordered independently – you can cache the content of a single regularly visited site or run a number of Internet sites with the default memory allocation. You can take full advantage of the Varnish platform if you use a dedicated IP and you can order one with your semi-dedicated server package as well. The Hepsia Control Panel will give you complete control over the platform and, with no more than one click, you’ll be able to clear the cache, to check a log or to restart an instance.
Varnish in VPS Servers
We offer Varnish with all of the Hepsia-managed Linux VPS servers, so in case you get a VPS with this web hosting Control Panel, you’ll be able to use the content caching platform at no additional charge. The Varnish platform can use different amounts of system memory for content caching purposes depending on the specific Virtual Private Server plan that you’ve chosen during the signup procedure, but nevertheless, this amount will not be less than several hundred megabytes. This is more than enough to enhance the overall performance of a number of large-scale websites, so the better page load speeds and the reduced load on the virtual server will be discernible. The result may not be observable instantly, as the Varnish platform will require a certain amount of time to cache the site content that people browse, but soon after you activate it, you’ll feel its full potential. This caching platform will permit you to use a lower-end server and to give less money to get the same performance you would get with a more powerful machine without Varnish.
Varnish in Dedicated Servers
You can use Varnish in order to speed up any website that is hosted on a dedicated server from our company when the Hepsia Control Panel is pre-installed on the machine. Not only will you get the content caching platform ready to be used at no additional cost, but you will also exert complete control over it via the Hepsia Control Panel’s simple-to-navigate GUI. It will take only one single mouse click to start or remove an instance or to delete the cached files for any site that’s using Varnish and if you’re more advanced, you can also browse the platform’s system logs. Varnish comes with at least 3 GB of memory for web content caching purposes, so even in case you host lots of sites on your machine and they all use the caching platform, the improvement in their performance will be detectable. You will just have to wait for a while till Varnish caches whatever web pages the visitors browse on their end. The Varnish platform works best if the sites use a dedicated IP, but owing to the fact that our dedicated servers come with 3 cost-free IP addresses, you’ll have all that you need.
