Varnish is a website accelerator tool, which has been gaining a lot of popularity in recent years, because it can increase the load speed of any site, at times even by 100 percent, based on the content itself. This tool is sometimes referred to as an HTTP reverse proxy as well and is used to lower the overall load on the physical server and to boost the browsing speed for the site visitors. Anytime a visitor loads a page on a particular site, the browser request is processed by the web server and the requested content is served as a response. If Varnish is enabled, it caches the pages that the website visitor opens and if any of them is accessed for a second time, it’s delivered by Varnish and not by the web server directly. The improvement in the overall performance comes from the fact that the accelerator processes the browser requests significantly faster than any web server, which results in much faster browsing speeds for the users. In case any data is changed meanwhile, the cached web pages will also be updated the next time someone accesses them.
Varnish in Web Hosting
In case you host your Internet sites under a web hosting account with our company, you will be able to activate Varnish with a few clicks from your hosting Control Panel. The content caching platform is available as an optional upgrade with all our web hosting plans and you can choose how many sites will use it and the total storage space that will be used 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 are not linked directly to each other, so you can decide whether you want a lot of memory for a single large-size site or less memory for several smaller ones. You can make use of the full potential of the Varnish caching platform in case the websites use a dedicated IP address. With the hosting Control Panel, you can swiftly start/reboot/discontinue an instance, clear the cached files independently for each site that employs the Varnish platform or check an in-depth system log.
Varnish in Semi-dedicated Servers
Varnish is offered as standard with all Linux semi-dedicated hosting service that we are offering and you can use it for workload balancing purposes. It’s available in your Hepsia Control Panel. The caching platform comes with 64 megabytes of system memory for cached data storing purposes and you can use it with any website that you host in your account. If you’re in need of more, you can increase the memory allocation. The memory itself is offered in increments of 32 megabytes through the Control Panel’s Upgrades section. The very same Upgrades section will permit you to create more instances as well, in case you wish to use the Varnish platform with more Internet sites. The two upgrades can be added separately – you can cache the content of one single traffic-consuming site or use several different websites with the default memory. You can get the most out of the Varnish platform in case you use a dedicated IP address and you can order one with your semi-dedicated plan as well. Hepsia will give you full control over the caching platform and, with no more than a click, you will be able to clear the cache, to check a system log or to restart an instance.
Varnish in VPS Servers
You can use Varnish with all our VPS server plans at no additional charge, since the content caching platform is pre-installed and is available by default. The sole condition is that the Virtual Private Server must be ordered with the Hepsia Control Panel, via which you will be able to activate Varnish for any of your sites with just a few mouse clicks. Each package features a different amount of memory for caching purposes, but you will get minimum several hundred MB, which is enough even for multiple traffic-heavy Internet sites. Soon after you activate the Varnish platform, it will start caching the content that your website visitors browse, so you’ll notice the substantially better web page loading times and the lowered load on the VPS in no time. Varnish will allow you to use a less costly virtual machine, as you will not require that many resources to warrant the uninterrupted operation of your sites even if you’ve got large-size sites with many visitors. Optimum results are accomplished if the websites that use Varnish also use a dedicated IP address.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia Control Panel, you will get Varnish at no additional fee and you’ll have complete control over it through an amazingly simple-to-work-with interface – you’ll be able to start, to cancel or to restart an instance, to view an elaborate system log, to clear the cached data for any Internet site and much, much more. Varnish will have several GB of virtual memory at its disposal, so even if you manage traffic-heavy websites with a large number of visitors, you will notice the considerably faster page loading times and the less load on the machine. This will become a fact shortly after you start using the Varnish platform, since it will require some time to cache the web pages that people open. You can make the most of the platform’s potential in case the Internet sites that are using it use also a dedicated IP address, but due to the fact that your dedicated server includes a couple of IP addresses by default, you won’t have to pay anything on top of the monthly fee for the server itself.
