Varnish is a website accelerator platform, which caches content for faster response times. It’s sometimes referred to as a caching HTTP reverse proxy as well and it interacts between a web server and a browser. When a site visitor loads a certain page, its content is requested by the web browser, and then the server handles this request and sends back the requested content. If Varnish is enabled for a specific website, it will cache its pages on the first visit and in case the visitor opens a cached page once more, the info will be delivered by the accelerator platform and not by the server. The increased load speed is a result of the much faster response time that the Varnish platform offers compared to any web server software. At the same time, this does not mean that the site visitors will continue seeing the same content over and over again, since any update on any of the pages is reflected in the content that the Varnish platform stores in its memory.
Varnish in Hosting
Varnish is available as an optional upgrade with each of our hosting. You can add it to your website hosting account via the Hepsia hosting Control Panel, which is offered with all shared web hosting packages and you will get a really simple-to-work-with graphical interface, which will grant you full control over the content caching system. Using 1-click quick-access controls, you can reboot or turn off any of the instances, i.e. Varnish will no longer work for a specific site. You can also see an elaborate system log file or erase the cache for any of the sites. When you add Varnish to your shared hosting package, you’ll be able to choose the total amount of memory that will be at your disposal for data caching purposes and how many websites will use Varnish. You can always add more memory in increments of 32 megabytes and, for optimum performance, you can assign a dedicated IP address to the websites that will use Varnish. This will enable you to take full advantage of your Internet sites and to have numerous pleased site visitors.
Varnish in Semi-dedicated Servers
The semi-dedicated servers offered by our company will permit you to employ Varnish once your brand new account has been created, since the caching platform is offered by default. 64 MB of system memory will be allocated to Varnish the second your account is activated, so you can use this workload distribution software once your site has been published on the Internet. If you are in need of more 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 instantly. 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 caching platform will considerably reduce the load on the server produced by your websites, so your site visitors can enjoy fast-loading pages. You’ll be able to manage the Varnish caching platform without efforts via the Hepsia Control Panel using fast-access controls. You will be able to start/shut down any of the instances that you’ve got, to clear the cached files for any of your Internet sites or to view system logs.
Varnish in VPS Servers
We provide Varnish with all of the Hepsia-managed VPS servers, so if you purchase a server with this Control Panel, you will be able to make use of the caching platform at no additional charge. Varnish can utilize different amounts of system memory for caching purposes depending on the very VPS package that you have selected during the registration process, but at any rate, this amount won’t be less than several hundred MB. This is quite enough to optimize the overall performance of several different busy sites, so the faster site load speeds and the reduced load on the VPS will be perceivable. The result may not be detectable momentarily, as Varnish will need some time to cache the site content that people request, but shortly after you activate it, you will observe its full potential. This caching platform will allow you to use a less powerful Virtual Private Server and to pay less cash to get the very same performance you’d get with a more powerful virtual machine without Varnish.
Varnish in Dedicated Servers
You can use Varnish to speed up any site that’s hosted on a dedicated server with us when the Hepsia Control Panel is pre-installed on it. Not only will you get the content caching platform ready for use at no additional charge, but you’ll also have full control over it via Hepsia’s user-friendly interface. It will take only one single mouse click to start or deactivate an instance or to delete the cached data associated with any Internet site that is using Varnish and if you’re more trained, you can also view the platform’s system logs. Varnish comes with no less than three gigabytes of memory for website content caching purposes, so even in case you run numerous sites on your machine and they all use the platform, the difference in their overall performance will be perceivable. You’ll simply have to wait for a while until Varnish caches whatever content the site visitors browse on their end. The Varnish platform performs best if the Internet sites use a dedicated IP, but since our servers come with 3 free IPs, you’ll have everything you need.
