Varnish is a website accelerator platform, which caches data for the sake of faster access. It is sometimes referred to as an HTTP reverse proxy too and it interacts between a web server and its users. When a site visitor loads a certain web page, its content is requested by the browser, and then the web server processes this browser request and returns the necessary content. If Varnish is enabled for a specific site, it will cache the pages at the first request and if the visitor opens a cached page for a second time, the data will be delivered by the accelerator platform instead of the server. The increased loading speed is a result of the significantly faster response time that Varnish offers compared with any web server software. Of course, this doesn’t mean that the visitors will continue being served the same content over and over again, as any modification on any of the pages is reflected in the content that Varnish keeps in its system memory.
Varnish in Cloud Website Hosting
You can make use of Varnish’s full potential and improve the load speed of your sites irrespective of the cloud website hosting package that you’ve chosen and you can add and set up the data caching platform with several clicks of the mouse through the simple-to-work-with interface offered by our next-generation Hepsia hosting Control Panel. During the procedure, you’ll be able to select two separate things – how many Internet sites will use the Varnish platform, i.e. the number of instances, and how much info will be cached, i.e. the amount of system memory. The latter is available in increments of 32 megabytes and is not linked to the number of instances, so you can order more instances with less memory and the other way around. If you’ve got lots of content on a certain Internet site and you receive a lot of visitors, more memory will give you better results. You may also consider employing a dedicated IP address for the websites that will use the Varnish caching platform. Hepsia will offer you easy one-click buttons for removing or rebooting any instance, for clearing the cache associated with each website and for seeing elaborate system logs.
Varnish in Semi-dedicated Hosting
The Varnish data caching platform is an essential part of the basic set of services that you’ll receive if you decide to host your websites in a semi-dedicated server account. You can set it up for any of your Internet sites through our leading-edge Hepsia Control Panel. The default amount of system memory that the Varnish caching platform can use to cache data is 64 MB, but in case you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this platform at the same time. Since these two features are not linked to each other, you can use a couple of Internet sites with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for one single site. The Varnish platform performs best when you use a dedicated IP address for the websites that utilize its power. Hepsia will provide you with a simple way of rebooting any instance. What’s more, you’ll be able to delete the cached contents with just one single mouse click.
Varnish in VPS Hosting
We offer Varnish with all Hepsia-equipped Linux VPS hosting, so if you obtain a server with this hosting Control Panel, you will be able to take advantage of the content caching platform at no additional charge. The Varnish platform can utilize different amounts of memory for caching purposes depending on the particular server configuration that you’ve selected during the order process, but in any case, this amount will not be less than several hundred MB. This is quite enough to boost the work of several different busy Internet sites, so the faster web page load speeds and the less load on your VPS will be perceptible. The effect may not be visible straight away, since the Varnish platform will need a certain amount of time to cache the site content that users request, but shortly after you set it up, you will perceive its full capacity. This caching platform will allow you to use a lower-end VPS server and to pay less money to get the very same performance you’d get with a more powerful virtual machine without Varnish.
Varnish in Dedicated Web Hosting
If you order a dedicated server with the Hepsia hosting Control Panel, you will get Varnish at no extra fee and you’ll exert full control over it through a really easy-to-navigate interface – you will be able to start, to delete or to reboot an instance, to see a detailed log, to delete the cached content associated with any site and much, much more. The Varnish platform will have several gigabytes of memory at its disposal, so even if you’ve got resource-swallowing websites with an enormous number of visitors, you’ll notice the considerably faster page loading speeds and the less load on your dedicated machine. This will become a fact shortly after you start using the Varnish platform, as it will require a certain amount of time to cache the website content that people browse. You can get the most out of the platform’s capacity if the Internet sites that are using it also use a dedicated IP, but considering the fact that your dedicated server comes with a few IP addresses by default, you will not have to pay anything on top of the monthly charge for the server itself.
