Varnish is a web app accelerator, which has been gaining a lot of popularity in recent years, because it can increase the load speed of any Internet site, sometimes even by one hundred percent, depending on the content. This tool is sometimes called a caching HTTP reverse proxy as well and is used to decrease the overall load on the server and to accelerate the access speed for the website visitors. Anytime a visitor accesses a page on a certain website, the web browser request is processed by the web server and the requested content is served as a reply. If Varnish is activated, it caches the pages that the visitor opens and if any of them is opened for a second time, it’s served by Varnish and not by the server directly. The increase in the performance comes from the fact that the accelerator handles the web requests tremendously faster than any web server, which results in much faster browsing speeds for the users. If any data is updated in the meantime, the cached pages will also be ‘refreshed’ the next time somebody opens them.
Varnish in Semi-dedicated Servers
Varnish is part of the default set of services that you’ll obtain if you decide to host your Internet sites in a semi-dedicated server account. You can activate it for any of your Internet sites via our next-gen Hepsia hosting Control Panel. The default amount of memory that Varnish can use to cache content is 64 megabytes, but in case you decide that you want more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this platform simultaneously. Since these two things are not tied to each other, you can use a few instances with the default amount of memory or you can add more memory in increments of 32 MB and use all of it for one single website. Varnish performs best when you assign a dedicated IP to the sites that utilize its power. The Hepsia Control Panel will provide you with an easy means of restarting any instance. What’s more, you will be able to delete the cached files with just one click of the mouse.
Varnish in VPS Servers
You can use Varnish with all our VPS server plans at no additional fee, as the platform is pre-installed and is included by default. The sole precondition is that the virtual machine must come with the Hepsia Control Panel, through which you will be able to set up Varnish for any of your Internet sites with only a couple of clicks of the mouse. Each Virtual Private Server plan includes a different amount of memory for content caching purposes, but you’ll have minimum several hundred megabytes, which is sufficient enough even for multiple traffic-heavy sites. Soon after you enable the Varnish platform, it will begin caching the content that your visitors browse, so you’ll notice the considerably faster Internet site load speeds and the reduced server load very soon. The Varnish caching platform will allow you to use a less expensive VPS server, since you won’t require that many resources to warrant the correct operation of your websites even if you run resource-hungry websites with many visitors. Optimal results are accomplished if the websites that use the Varnish caching platform use also a dedicated IP.
Varnish in Dedicated Servers
When you need a more powerful hosting solution and you acquire any of the Linux dedicated web hosting plans that we are offering, you’ll be able to use the Varnish content caching platform to optimize the overall performance of your websites at no extra cost on the condition that the dedicated machine is ordered with our next-gen Hepsia Control Panel. Its simple-to-use GUI will allow you to keep track of system processes, to delete the cached contents or to restart any instance with one click. The smallest amount of system memory that Varnish can use to cache content is 3 gigabytes, which is more than enough for a large number of busy Internet sites, so your server will be able to deal with a gigantic system load while your website visitors are enjoying a smooth web browsing experience. Since your server will come with a number of dedicated IPs, you will be able to make use of Varnish’s maximum potential.
