Varnish is a website accelerator, which has been gaining a lot of popularity lately, as it can increase the load speed of any Internet site, at times even by 100%, depending on the content itself. This tool is sometimes called an HTTP reverse proxy as well and is used to lower the overall load on the physical machine and to boost the browsing speed for the website visitors. Whenever a visitor loads a page on a certain site, the web browser request is taken care of by the web server and the requested info is returned as a response. If the Varnish accelerator is activated, it caches the pages that the website visitor browses and in case any of them is opened once more, it is served by Varnish and not by the web server directly. The increase in the overall performance is due to the fact that the accelerator handles the browser requests substantially quicker than any web server, which leads to much faster browsing speeds for the visitors. In case any data is updated meanwhile, the cached pages will also be ‘refreshed’ the next time someone tries to access them.
Varnish in Shared Hosting
If you host your websites under a shared hosting account with us, you’ll be able to activate Varnish with a couple of clicks of the mouse via your Control Panel. The platform is offered as an upgrade with all our shared web hosting packages and you can choose how many websites will use it and the maximum amount of system memory that will be used for the cached data. The two features that can be upgraded in the Upgrades section of the Control Panel are the number of instances and the amount of system memory and they’re not directly linked to each other, so you can decide if you want lots of memory for one large-size site or less memory for several smaller ones. You can unleash the full potential of the Varnish caching platform in case the sites use a dedicated IP. Using the hosting Control Panel, you can easily start/reboot/delete an instance, clear the cached files independently for each website which employs the Varnish platform or see a detailed system log.
Varnish in Semi-dedicated Servers
The Varnish data caching platform is an essential part of the standard service set that you’ll obtain when you choose to host your websites under a semi-dedicated server account. You can configure it for any of your sites via our innovative Hepsia Control Panel. The default memory that the Varnish platform can use to cache data is 64 megabytes, but in case you decide that you want more, you can upgrade this amount from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the websites that can use this caching platform at the same time. As these two things are not linked to each other, you can use a few websites with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for a single web site. The Varnish caching platform works best if you get a dedicated IP for the websites that utilize its power. The Hepsia Control Panel will offer you an easy means of rebooting any instance. What’s more, you’ll be able to clear the cached contents with just one single click of the mouse.
Varnish in VPS Servers
You can use Varnish with any of our VPS server plans at no additional cost, as the data caching platform is pre-installed and is offered by default. The only condition is that the Virtual Private Server must come with the Hepsia hosting Control Panel, via which you will be able to set up Varnish for any of your websites with only a couple of mouse clicks. Each Virtual Private Server package offers a different amount of system memory for data caching purposes, but you will get minimum several hundred megabytes, which is sufficient enough even for multiple resource-hungry websites. Shortly after you enable the Varnish platform, it will begin caching the content that your website visitors browse, so you will notice the much faster webpage loading speeds and the decreased server load very soon. The Varnish caching platform will allow you to use a less costly virtual server, since you will not need that much power to ensure the correct operation of your websites even if you own large-size Internet sites with a lot of visitors. Optimal results are accomplished if the sites which use the Varnish platform also use a dedicated IP.
Varnish in Dedicated Servers
If you want the most powerful web hosting solution and you get any of the Linux dedicated servers that we’re offering, you can use the Varnish platform to boost the overall performance of your sites at no extra fee on the condition that the dedicated machine is ordered with our advanced Hepsia hosting Control Panel. Its easy-to-work-with graphical interface will permit you to keep an eye on platform processes, to delete the cache or to reboot any instance with one click. The minimal amount of system memory that the Varnish caching platform can use to cache Internet site content is 3 GB, which is quite enough for a huge number of traffic-intensive websites, so your server will be able to deal with an enormous system load while your site visitors are enjoying a seamless browsing experience. As your machine will come with several different dedicated IP addresses, you’ll be able to make use of Varnish’s maximum capacity.
