Varnish is a web app accelerator platform, which caches information for faster response times. It’s occasionally called an HTTP reverse proxy as well and it works between a web server and its users. When a visitor opens a given web page, the content is requested by the web browser, and then the server processes this request and sends back the necessary info. If Varnish is enabled for a certain website, it will cache the pages at the first visit and if the user visits a cached page once again, the content will be delivered by the accelerator platform and not by the web server. The accelerated speed is an end result of the considerably faster response time that Varnish offers as compared with any server software. At the same time, this doesn’t mean that the site visitors will keep seeing the same content over and over again, since any change on any of the web pages is reflected in the content that the Varnish platform saves in its memory.
Varnish in Shared Hosting
In case you host your websites in a shared hosting account with us, you will be able to add Varnish with a few clicks through your Control Panel. The platform comes as an upgrade with all our shared hosting packages and you can select the number of the websites that will use it and the maximum storage space that will be used for the cached content. The two upgradeable features in the Control Panel’s Upgrades section are the amount of memory and the number of instances and they’re not directly tied to each other, so you can choose if you want a lot of memory for one single large-sized site or less memory for several smaller ones. You can use the full potential of the Varnish caching platform in case the sites use a dedicated IP. Using the hosting Control Panel, you can effortlessly start/restart/cancel an instance, clear the cached contents individually for each site that employs Varnish or view an in-depth log.
Varnish in Semi-dedicated Servers
The Linux semi-dedicated servers that we offer will permit you to employ Varnish once your new semi-dedicated server account has been created, as the content caching platform comes by default. 64 megabytes of system memory will be allocated to Varnish the moment your account is enabled, so you can take advantage of this workload balancing software once your website has been built. In case you’re in need of more system memory, you can add 32 MB at a time from the Hepsia hosting Control Panel’s Upgrades section and it will be allocated to your semi-dedicated machine right away. You can also increase the number of the sites 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 freedom. The platform will seriously decrease the load on the machine produced by your sites, so your site visitors can enjoy fast-loading web pages. You’ll be able to manage the Varnish caching platform without any effort through your Hepsia Control Panel using fast-access buttons. You will be able to start/shut down any of the instances that you have, to clear the cache for any of your websites or to check system logs.
Varnish in VPS Servers
We provide Varnish with all of the Hepsia-managed Linux VPS plans, so in case you get a VPS with this hosting Control Panel, you will be able to take advantage of the caching platform at no additional cost. Varnish can utilize different amounts of memory for content caching purposes depending on the very configuration that you’ve picked during the signup process, but at any rate, this amount won’t be less than several hundred megabytes. This is more than enough to boost the performance of a number of large-size websites, so the better website browsing speeds and the decreased load on the virtual server will be noticeable. The result may not be detectable momentarily, as Varnish will need some time to cache the website content that visitors browse, but shortly after you set it up, you will feel its full capacity. This caching platform will permit you to use a less powerful VPS and to give less money to get the very same performance you would get with a more powerful virtual machine without Varnish.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia Control Panel, you’ll acquire Varnish at no extra cost and you will have complete control over it through an incredibly easy-to-use GUI – you’ll be able to start, to terminate or to restart an instance, to browse a detailed log, to clear the cached files associated with any Internet site and much, much more. The Varnish platform will have several gigabytes of virtual memory at its disposal, so even if you’ve got resource-consuming websites with a large number of visitors, you will notice the substantially better web page loading times and the lowered load on your dedicated machine. This will become a fact shortly after you begin using the Varnish platform, since it will require a certain amount of time to cache the website content that users access. You can get the most out of the platform’s capacity in case the Internet sites that are using it also use a dedicated IP address, but considering the fact that your server comes with a few IP addresses by default, you won’t have to pay anything on top of the monthly fee for the server itself.
