Learn precisely what Varnish is. Discover more about web accelerators and their role.
Varnish is a data caching platform, which is sometimes referred to as an HTTP reverse proxy. It is a website accelerator tool that can accelerate the speed of a website by up to one thousand percent, depending on the content itself. Each time a visitor accesses any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server if the visitor opens it again. In this way, the browser request from the visitor is not processed by the server and the web page will load significantly faster, as Varnish can deliver information many times faster than any web server software. The result will be a significantly faster loading website, which leads to an improved browsing experience. When any of the cached pages is updated on the actual site, the info that Varnish caches in its system memory is ‘refreshed’ too, so the users will never end up seeing old info.
Varnish in Cloud Hosting
If you host your sites under a cloud hosting
account with our company, you will be able to activate Varnish with a few mouse clicks via your Control Panel. The platform comes as an upgrade with all our shared hosting plans and you can choose how many sites will use it and the total amount of system memory that will be available for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they aren’t directly tied to each other, so you can choose whether you want plenty of memory for one single large-sized site or less memory for multiple smaller ones. You can take advantage of the full potential of the Varnish caching platform if the sites use a dedicated IP. With the Control Panel, you can easily start/restart/cancel an instance, delete the cached contents independently for each website that uses the Varnish platform or check a detailed log.
Varnish in Semi-dedicated Servers
The semi-dedicated servers
offered by our company will allow you to use Varnish once your new semi-dedicated server account has been created, as the content caching platform comes by default. 64 MB of system memory will be assigned to Varnish the moment your account is activated, so you can make use of this workload balancing software once you launch your website. If you are in need of more system memory, you can add 32 MB at a time from the Upgrades section of the Hepsia hosting Control Panel and it will be assigned to your semi-dedicated machine in an instant. You can also increase the number of the Internet sites that use Varnish, or the so-called ‘instances’, which are not directly tied to the amount of memory that you use, which means that you’ll have more versatility. The Varnish caching platform will significantly reduce the load generated by your sites, so your site visitors can enjoy fast-opening pages. You’ll be able to manage the Varnish caching platform without efforts from your Control Panel using quick-access controls. You’ll be able to start/terminate any of the instances that you have, to clear the cache associated with any of your Internet sites or to view system log files.
Varnish in VPS Servers
We provide Varnish with all Hepsia-equipped VPS hosting plans
, so in case you purchase a VPS with this hosting Control Panel, you will be able to take full advantage of the caching platform at no additional cost. Varnish can use different amounts of system memory for content caching purposes based on the specific Virtual Private Server package that you’ve chosen during the registration process, but in any case, this amount won’t be less than several hundred MB. This is quite enough to enhance the overall performance of several different traffic-consuming websites, so the faster page browsing speeds and the lowered load on your virtual server will be perceivable. The effect may not be distinguishable straight away, since Varnish will need a certain amount of time to cache the site content that users open, but shortly after you activate it, you will perceive its full capacity. This platform will permit you to use a lower-end Virtual Private Server and to pay less money to get the exact same performance you would get with a more powerful virtual machine without Varnish.
Varnish in Dedicated Servers
You can use Varnish in order to optimize the speed of any website that’s hosted on a dedicated server
from us when the Hepsia Control Panel is pre-installed on the machine. Not only will you get the caching platform ready for use at no additional fee, but you will also exert complete control over it through the Hepsia Control Panel’s user-friendly graphical interface. It will take only one single click to start or disable an instance or to clear the cached data for any Internet site that’s using the Varnish platform and in case you’re more tech-savvy, you can also view the platform’s logs. Varnish comes with at least three gigabytes of virtual memory for site content caching purposes, so even if you host lots of sites on your dedicated server and they all use the platform, the improvement in their overall performance will be perceivable. You will simply have to wait for a little while until Varnish caches whatever webpages the website visitors browse on their end. The Varnish platform works best when the websites use a dedicated IP address, but owing to the fact that our servers include 3 free-of-cost IP addresses, you will have all that you need.
