Varnish is a web accelerator tool, which has been gaining a lot of popularity in recent years, because it can increase the speed of any Internet site, at times even by one hundred percent, depending on the content itself. This tool is occasionally called a caching HTTP reverse proxy as well and is used to lower the overall server load and to enhance the browsing speed for the website visitors. Whenever a visitor accesses a page on a given website, the web browser request is processed by the web server and the requested info is returned as a response. If Varnish is enabled, it caches the web pages that the website visitor browses and in case any of them is accessed for a second time, it is served by Varnish and not by the web server directly. The increase in the overall performance comes from the fact that the accelerator handles the browser requests substantially faster than any web server, which results in much faster browsing speeds for the site visitors. If any data is modified in the meantime, the cached pages will also be ‘refreshed’ the next time somebody attempts to open them.
Varnish in Shared Hosting
You can unleash Varnish’s full potential and increase the speed of your websites irrespective of the shared hosting plan that you have picked and you can activate and set up the platform with a few mouse clicks via the user-friendly graphical interface offered by our next-generation Hepsia hosting Control Panel. In the meantime, you will be able to choose two different things – how many sites will use Varnish, in other words – the number of instances, and how much data will be cached, i.e. the amount of memory. The latter is available in increments of 32 megabytes and is not tied to the number of instances, so you can add more instances and less memory and vice versa. In case you have plenty of content on a certain Internet site and you win lots of visitors, more system memory will guarantee you a better result. You may also consider using a dedicated IP address for the sites that will use the Varnish platform. Hepsia will offer you simple one-click buttons for turning off or restarting any instance, for erasing the cache associated with each site and for seeing comprehensive logs.
Varnish in Semi-dedicated Servers
The semi-dedicated plans offered by our company will permit you to use Varnish as soon as your brand-new semi-dedicated account has been opened, since the caching platform is available by default. 64 megabytes of system memory will be allocated to Varnish the second your account is enabled, so you can take advantage of this workload balancing software as soon as you launch your website. If you’re in need of more system memory, you can get 32 megabytes at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated machine straight away. You can also increase the number of the websites that use Varnish, or the so-called ‘instances’, which are not bound directly to the amount of memory that you use, which means that you will have more freedom. The caching platform will seriously decrease the load on the machine caused by your sites, so your site visitors can enjoy fast-loading pages. You’ll be able to manage the Varnish platform without any effort through your Control Panel using quick-access controls. You will be able to start/stop any of the instances that you’ve got, to delete the cache associated with any of your sites or to see system log files.
Varnish in VPS Servers
We provide Varnish with all Hepsia-equipped Linux VPS hosting plans, so if you purchase a server with this web hosting Control Panel, you will be able to make full use of the caching platform at no additional cost. Varnish can utilize different amounts of memory for data caching purposes depending on the very configuration that you’ve selected during the server order process, but in any case, this amount will not be less than several hundred MB. This is quite enough to boost the work of several large sites, so the faster site browsing speeds and the reduced load on the Virtual Private Server will be perceivable. The result may not be evident immediately, since the Varnish platform will require a certain amount of time to cache the website content that people browse, but soon after you set it up, you’ll feel its full capacity. This platform will permit you to use a less powerful VPS server and to give less money to get the same performance you would get with a higher-end virtual machine without Varnish.
Varnish in Dedicated Servers
If you need a more powerful website hosting solution and you obtain any of the Linux dedicated web hosting plans offered by us, you’ll be able to use the Varnish data caching platform to boost the overall performance of your sites at no extra cost on the condition that the server is ordered with our avant-garde Hepsia hosting Control Panel. Its simple-to-use graphical interface will allow you to keep track of platform processes, to clear the cached contents or to reboot any instance with a click. The smallest amount of memory that the Varnish caching platform can employ to cache Internet site content is 3 GB, which is quite enough for an enormous number of resource-absorbing websites, so your server will be able to handle an immense system load while your visitors are enjoying a seamless browsing experience. Since your dedicated server will include several different dedicated IP addresses, you’ll be able to make use of Varnish’s full capacity.
