Varnish is a web accelerator platform, which caches data for quicker response times. It is occasionally referred to as an HTTP reverse proxy too and it works between a web server and an Internet browser. When a website visitor opens a specific page, its content is requested by the Internet browser, and then the web server handles this browser request and returns the required content. If Varnish is enabled for a certain site, it will cache its pages on the very first visit and if the visitor opens a cached page for a second time, the data will be delivered by the accelerator platform and not by the server. The increased load speed is a result of the considerably faster response speed that Varnish offers compared with any web server software. Of course, this does not mean that the website visitors will keep being served the very same content over and over again, as any change on any of the web pages is reflected in the content that the Varnish platform stores in its system memory.
Varnish in Cloud Hosting
Varnish is offered as an optional upgrade with each of our Linux cloud hosting. You can add it to your hosting account via the Hepsia Control Panel, which comes with all shared web hosting packages and you’ll get an amazingly easy-to-work-with graphical interface, which will give you full control over the data caching system. Using 1-click fast-access controls, you can reboot or delete any of the instances, i.e. Varnish will no longer be enabled for a given Internet site. You can also check an elaborate system log or erase the cache associated with any of the websites. When you add Varnish to your shared hosting package, you will be able to select the total amount of memory that will be at your disposal for content caching purposes and the number of the sites that will use Varnish. You can always get more memory in increments of 32 megabytes and, for maximum performance, you can assign a dedicated IP to the sites that will use Varnish. This will enable you to get the most out of your sites and to have plenty of happy users.
Varnish in Semi-dedicated Servers
Varnish is a feature, which is offered by default with all semi-dedicated servers offered by our company and you can use it for load balancing purposes. It is available in your Hepsia hosting Control Panel. The platform comes with 64 megabytes of system memory for cached data storing purposes and you can employ it with any Internet site that you host in your semi-dedicated account. In case you need more, you can increase the memory quota. The memory itself is offered in increments of 32 megabytes through the Control Panel’s Upgrades section. The same Upgrades section will enable you to activate more instances as well, if you would like to use the Varnish platform with multiple websites. The two upgrades can be added separately – you can cache the content of a single resource-demanding website or use several different Internet sites with the default memory quota. You can get the most out of the Varnish platform if you use a dedicated IP and you can get one with your semi-dedicated package as well. The Hepsia Control Panel will grant you total control over the platform and, with no more than one single click of the mouse, you’ll be able to delete the cached contents, to see a system log file or to restart an instance.
Varnish in VPS Servers
We provide Varnish with all of the Hepsia-equipped VPS servers, so if you get a VPS with this hosting Control Panel, you’ll be able to make use of the content caching platform at no additional charge. Varnish can utilize different amounts of memory for caching purposes based on the particular VPS plan that you have picked on the order page, but in any case, this amount will not be less than several hundred MB. This is more than enough to optimize the performance of a number of busy Internet sites, so the faster web page loading speeds and the lowered load on the machine will be discernible. The result may not be observable immediately, as the Varnish platform will need some time to cache the website content that visitors request, but shortly after you set it up, you’ll observe its full capacity. This platform will allow you to use a lower-end VPS and to pay less cash to get the same performance you’d get with a more powerful virtual machine without Varnish.
Varnish in Dedicated Servers
You can use Varnish to optimize the speed of any website that’s hosted on a dedicated server from our company when the Hepsia hosting Control Panel is installed on the machine. Not only will you get the data caching platform ready for use at no additional fee, but you’ll also exert full control over it via Hepsia’s easy-to-navigate graphical interface. It’ll take just one single click of the mouse to start or stop an instance or to clear the cache associated with any site that’s using Varnish and in case you’re more tech-savvy, you can also see the platform’s logs. Varnish comes with at least three gigabytes of memory for caching purposes, so even if you host a large number of websites on your machine and they all use the Varnish caching platform, the difference in their overall performance will be apparent. You’ll simply have to wait for a little while until Varnish caches whatever web pages the visitors access on their end. The Varnish platform performs best if the Internet sites use a dedicated IP, but considering the fact that our dedicated servers include 3 cost-free IPs, you’ll have all that you need.
