Varnish is a web accelerator platform, which caches information for quicker access. It is sometimes called an HTTP reverse proxy too and it works between a web server and a web browser. When a website visitor loads a certain webpage, its content is requested by the Internet browser, and then the server processes this browser request and sends back the needed data. If Varnish is enabled for a website, it will cache its pages at the very first visit and in case the user accesses a cached page again, the info will be delivered by the accelerator platform instead of the web server. The accelerated speed is an end result of the considerably faster response speed that the Varnish platform offers compared to any web server software. At the same time, this doesn’t mean that the website visitors will keep seeing the very same content again and again, because any change on any of the web pages is reflected in the content that Varnish caches in its memory.
Varnish in Shared Website Hosting
Varnish comes as an optional upgrade with all our Linux shared website hosting packages. You can add it to your hosting account through the Hepsia Control Panel, which is available with all shared hosting packages and you will get an amazingly user-friendly graphical interface, which will grant you full control over the content caching platform. Using one-click fast-access controls, you can reboot or discontinue any of the instances, i.e. Varnish will no longer be enabled for a given site. You can also view a comprehensive system log or clear the cache for any of the sites. When you add Varnish to your shared web hosting package, you will be able to select the maximum amount of system memory that will be available to you for content caching purposes and how many websites will use Varnish. You can always get more memory in increments of 32 MB and, for optimal performance, you can allocate a dedicated IP to the sites that will use Varnish. This will allow you to take full advantage of your websites and to have a lot of satisfied website visitors.
Varnish in Semi-dedicated Hosting
The Linux semi-dedicated hosting packages that we are offering will allow you to employ Varnish once your new semi-dedicated account is active, since the content caching platform is available by default. 64 megabytes of system memory will be allocated to Varnish the second your account is activated, so you can use this load distribution software once you launch your website. In case you’re in need of more system memory, you can add 32 MB at a time from the Hepsia hosting Control Panel’s Upgrades section and it will be assigned to your semi-dedicated server right away. You can also increase the number of the Internet sites that use Varnish, or the so-called ‘instances’, which are not directly linked to the amount of memory that you use, which suggests that you’ll have more freedom. The caching platform will seriously lower the load on the semi-dedicated machine that your websites generate, so your site visitors can enjoy fast-opening pages. You will be able to manage the Varnish platform without efforts via your Hepsia Control Panel using quick-access controls. You’ll be able to start/remove any of the instances that you have, to clear the cached data for any of your websites or to check system logs.
Varnish in Dedicated Hosting
You can use Varnish in order to increase the speed of any site that is hosted on a dedicated server from us when the Hepsia hosting Control Panel is installed on the machine. Not only will you get the data caching platform ready to be used at no extra charge, but you will also exert full control over it via the Hepsia Control Panel’s simple-to-work-with graphical interface. It will take just one single click of the mouse to start or deactivate an instance or to delete the cached content for any site that’s using the Varnish platform and if you are more tech-savvy, you can also browse the platform’s system logs. Varnish comes with no less than three gigabytes of virtual memory for caching purposes, so even in case you run a large number of sites on your dedicated machine and they all use the Varnish caching platform, the difference in their overall performance will be perceivable. You’ll simply have to wait for a while till Varnish caches whatever pages the visitors load on their end. The Varnish platform works best when the Internet sites use a dedicated IP address, but since our servers come with three free-of-charge IP addresses, you’ll have all that you need.
