Varnish is a web app accelerator, 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 referred to as a caching HTTP reverse proxy too and is used to lower the overall load on the physical machine and to accelerate the access speed for the website visitors. Anytime a visitor accesses a page on a particular site, the browser request is handled by the web server and the requested info is sent as a response. If the Varnish accelerator is activated, it caches the pages that the website visitor browses and if any of them is opened again, it is delivered by Varnish and not by the server directly. The performance increase is due to the fact that the accelerator handles the browser requests significantly faster than any web server, which results in much faster browsing speeds for the visitors. If any content is updated meanwhile, the cached web pages will also be updated the next time someone attempts to access them.

Varnish in Web Hosting

In case you host your websites in a web hosting account with us, you’ll be able to add Varnish with several clicks through your Control Panel. The platform comes as an optional upgrade with all our shared packages and you can choose how many sites will use it and the maximum storage space that will be used for the cached content. 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 aren’t linked directly to each other, so you can choose if you want lots of memory for one single large-size website or less memory for multiple smaller ones. You can unleash the full potential of Varnish if the sites use a dedicated IP. With the hosting Control Panel, you can swiftly start/reboot/disable an instance, delete the cached contents individually for each website that employs the Varnish platform or see an in-depth log file.

Varnish in Semi-dedicated Servers

The semi-dedicated servers that we are offering will permit you to use Varnish once your new semi-dedicated account has been set up, as the caching platform comes by default. 64 MB of system memory will be allocated to Varnish the second your account is activated, so you can use this load balancing software as soon as your site has been published online. If you need more system memory, you can get 32 MB at a time from the Hepsia hosting Control Panel’s Upgrades section and it will be allocated to your semi-dedicated machine in an instant. 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 goes to say that you’ll have more flexibility. The Varnish platform will substantially reduce the load that your sites generate, so your website visitors can enjoy fast-loading pages. You’ll be able to manage the Varnish platform with ease via your Hepsia Control Panel using quick-access controls. You’ll be able to start/stop any of the instances that you’ve got, to delete the cached content associated with any of your Internet sites or to view system log files.

Varnish in VPS Servers

We provide Varnish with all of the Hepsia-managed VPS servers, so if you purchase a VPS with this hosting Control Panel, you will be able to make the most of the content caching platform at no extra fee. Varnish can use different amounts of memory for caching purposes depending on the specific server configuration that you have chosen during the signup procedure, but nevertheless, this amount will not be less than several hundred MB. This is more than enough to improve the performance of a handful of large-sized sites, so the faster site loading speeds and the lowered load on the server will be discernible. The effect may not be observable instantly, since the Varnish platform will need a certain amount of time to cache the website content that people browse, but shortly after you enable it, you’ll perceive its full capacity. This caching platform will permit you to use a less powerful VPS and to give less cash to get the exact same performance you would get with a higher-end machine without Varnish.

Varnish in Dedicated Servers

You can use Varnish in order to increase the speed of any website that is hosted on a dedicated server from us if the Hepsia Control Panel is pre-installed on it. Not only will you get the data caching platform ready to be used at no extra fee, but you will also exert total control over it via Hepsia’s simple-to-work-with GUI. It’ll take only a click to start or deactivate an instance or to delete the cached data for any website that’s using Varnish and if you’re more proficient, you can also check the platform’s system logs. Varnish comes with no less than 3 gigabytes of memory for site content caching purposes, so even in case you host lots of websites on your dedicated server and they all use the Varnish platform, the difference in their performance will be obvious. You will simply have to wait for a while till Varnish caches whatever pages the website visitors access on their end. The Varnish platform performs best when the Internet sites use a dedicated IP address, but since our dedicated servers come with 3 free IPs, you’ll have everything you need.
