Varnish is a website accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the speed of any site, sometimes even by 100 percent, depending on the content. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to lower the overall load on the physical server and to increase the access speed for the website visitors. Whenever a visitor opens a page on a particular Internet site, the browser request is processed 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 visitor opens and in case any of them is opened once again, it is fetched by Varnish and not by the server directly. The increase in the overall performance comes from the fact that the accelerator handles the browser requests substantially faster than any web server, which results in much faster browsing speeds for the users. If any content is modified meanwhile, the cached web pages will also be updated the next time somebody tries to open them.

Varnish in Cloud Hosting

Varnish is available as an optional upgrade with all our cloud service. You can add it to your web hosting account via the Hepsia Control Panel, which is offered with all shared web hosting plans and you will get a pretty simple-to-work-with GUI, which will give you complete control over the data caching system. Using 1-click fast-access buttons, you can reboot or remove any of the instances, i.e. Varnish will no longer be enabled for a certain Internet site. You can also view a comprehensive system log file or delete the cache for any of the websites. When you add Varnish to your shared hosting plan, you will be able to choose the total amount of system memory that will be at your disposal for data caching purposes and how many sites will use Varnish. You can always order more memory in increments of 32 MB and, for maximum performance, you can get a dedicated IP for the sites that will use Varnish. This will enable you to get the most out of your Internet sites and to have lots of pleased visitors.

Varnish in Semi-dedicated Servers

Varnish comes by default with all semi-dedicated servers offered by our company and you can use it for load balancing purposes. It’s available in your Hepsia hosting Control Panel. The content caching platform comes with 64 MB of system memory for cached data storing purposes and you can use it with any Internet site that you host in your semi-dedicated account. If you are in need of more than that, you can increase the memory allocation. The memory itself is available in increments of 32 megabytes in the Upgrades section of the Control Panel. The very same section will permit you to add more instances as well, if you’d like to use the Varnish caching platform with multiple websites. The two upgrades can be ordered separately – you can cache the content of a single traffic-hungry website or run a number of Internet sites with the default memory allowance. You can get the most out of Varnish in case you’ve got a dedicated IP and you can get one with your semi-dedicated package as well. The Hepsia Control Panel will grant you full control over the caching platform and, with no more than one click of the mouse, you’ll be able to delete the cached files, to view a system log file or to restart an instance.

Varnish in VPS Servers

We provide Varnish with all Hepsia-managed Linux VPS service, so in case you buy a VPS with this hosting Control Panel, you’ll be able to make use of the content caching platform at no additional cost. The Varnish platform can use different amounts of system memory for data caching purposes depending on the specific server configuration that you’ve picked during the subscription process, but at any rate, this amount will not be less than several hundred megabytes. This is more than enough to optimize the overall performance of a number of traffic-consuming websites, so the better website load speeds and the decreased load on the VPS server will be noticeable. The effect may not be evident immediately, since the Varnish platform will need some time to cache the site content that visitors access, but shortly after you enable it, you’ll witness its full capacity. This caching platform will permit you to use a less powerful Virtual Private Server and to pay less cash to get the exact same performance you’d get with a more powerful virtual machine without Varnish.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish caching platform at no extra fee and you’ll have total control over it via a rather easy-to-navigate interface – you will be able to start, to cancel or to reboot an instance, to see an elaborate log, to delete the cache associated with any website and much more. Varnish will have several GB of system memory at its disposal, so even if you manage resource-absorbing sites with a huge number of visitors, you’ll notice the significantly faster website load times and the less load on the dedicated machine. This will become a fact soon after you begin using the Varnish platform, since it will need a certain amount of time to cache the website content that visitors open. You can get the most out of the platform’s capability if the sites that are using it also use a dedicated IP, but considering the fact that your dedicated server includes several IPs by default, you won’t need to pay anything on top of your monthly fee for the server itself.
