Varnish is a web accelerator platform, which caches information for the sake of quicker access. It’s sometimes referred to as an HTTP reverse proxy as well and it interacts between a web server and a web browser. When a site visitor opens a certain webpage, the content is requested by the Internet browser, and then the server processes this browser request and sends back the required info. If Varnish is activated for a site, it will cache the pages at the first visit and if the visitor opens a cached page again, the data will be delivered by the accelerator platform instead of the web server. The boosted loading speed is an end result of the considerably faster response time that the Varnish platform offers compared to any web server software. Of course, this does not mean that the visitors will continue seeing the same content again and again, since any update on any of the web pages is reflected in the content that the Varnish platform stores in its memory.
Varnish in Cloud Hosting
Varnish comes as an optional upgrade with all our Linux cloud hosting. You can add it to your website hosting account from the Hepsia Control Panel, which is available with all shared hosting packages and you will get a pretty easy-to-use GUI, which will give you full control over the content caching platform. Using one-click quick-access controls, you can reboot or delete any of the instances, i.e. Varnish will no longer work for a given website. You can also view a comprehensive system log or delete the cache associated with any of the sites. When you add Varnish to your shared hosting package, you will be able to choose the total amount of memory that will be available to you for caching purposes and the number of the websites that will use Varnish. You can always get more memory in increments of 32 megabytes and, for optimum performance, you can allocate a dedicated IP address to the sites that will use Varnish. This will enable you to get the most out of your websites and to have plenty of gratified website visitors.
Varnish in Semi-dedicated Servers
Varnish comes by default with all Linux semi-dedicated service that we offer and you can use it for load balancing purposes. It’s available in your Hepsia hosting Control Panel. The Varnish content caching platform comes with 64 MB of system memory for cached content storing purposes and you can use it with any site that you host in the semi-dedicated account. If you’re in need of more than that, you can increase the system memory quota. The memory itself is offered in increments of 32 megabytes in the Upgrades section of the Control Panel. The same Upgrades section will permit you to create more instances as well, if you wish to use the Varnish platform with more Internet sites. The two upgrades can be added separately – you can cache the content of one single large-scale site or use a number of Internet sites with the default memory quota. You can get the most out of the Varnish caching platform if you’ve got a dedicated IP and you can order one with your semi-dedicated server package as well. Hepsia will grant you total control over the caching platform and, with no more than a click, you’ll be able to clear the cached contents, to view a log file or to reboot an instance.
Varnish in VPS Servers
The Varnish data caching platform comes by default with each of the VPS servers that we offer as long as the server is ordered with the Hepsia hosting Control Panel, so you can optimize the overall performance of your websites with just a few mouse clicks. The more powerful the plan, the more system memory Varnish will have at its disposal, but even with a less powerful package, the caching platform will be able to utilize several hundred MB, so even if you run a handful of Internet sites, you will notice a substantial reduction in the overall server load and a tremendously faster site load speed. The Varnish caching platform will have to work for a while as the users browse the pages and once the site content has been cached, you will notice the effects. One of the pluses of employing Varnish is that a less powerful and less high-priced package will do the very same job as a more pricey one without the caching platform, so not only will your sites work considerably better, but you will also save a certain amount of cash.
Varnish in Dedicated Servers
You can employ Varnish to accelerate any website that is hosted on a dedicated server from our company when the Hepsia Control Panel is installed on the machine. Not only will you get the content caching platform ready to be used at no additional fee, but you’ll also have full control over it through Hepsia’s intuitive graphical interface. It will take only one single mouse click to start or remove an instance or to delete the cached data for any website that’s using the Varnish platform and if you’re more competent, you can also check the platform’s logs. Varnish comes with at least 3 gigabytes of virtual memory for site content caching purposes, so even if you run an enormous number of Internet sites on your server and they all use the caching platform, the difference in their overall performance will be distinguishable. You will simply have to wait for a little while till Varnish caches whatever web pages the website visitors load on their end. The Varnish platform performs best when the Internet sites use a dedicated IP address, but owing to the fact that our servers come with three cost-free IP addresses, you’ll have everything you need.
