Varnish is a web app accelerator platform, which caches info for the sake of quicker response times. It is sometimes called a caching HTTP reverse proxy as well and it works between a web server and a browser. When a site visitor accesses a given page, its content is requested by the browser, and then the server processes this request and sends back the requested info. If Varnish is enabled for a specific website, it will cache its pages on the first request and if the user visits a cached page once more, the information will be delivered by the accelerator platform instead of the server. The accelerated speed is an end result of the substantially faster response speed that the Varnish platform offers compared to any server software. At the same time, this does not mean that the users will continue seeing the same content again and again, as any change on any of the web pages is reflected in the content that the Varnish platform caches in its system memory.
Varnish in Shared Hosting
In case you host your Internet sites in a shared hosting account with us, you will be able to activate Varnish with a few mouse clicks via your hosting Control Panel. The caching platform is offered as an optional upgrade with all our shared hosting packages and you can choose how many websites will use it and the total amount of system memory that will be available for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they are not tied directly to each other, so you can choose if you need a lot of memory for one single large-sized site or less memory for several smaller ones. You can unlock the full potential of the Varnish platform if the websites use a dedicated IP. Using the Control Panel, you can effortlessly start/reboot/deactivate an instance, delete the cached contents independently for each site that uses Varnish or view a detailed log.
Varnish in Semi-dedicated Hosting
Varnish is included by default with all Linux semi-dedicated hosting packages that we’re offering and you can use it for load distribution purposes. It is available in your Hepsia hosting Control Panel. The Varnish 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 account. If you’re 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 exact same section will enable you to create more instances too, if you wish to use the Varnish caching platform with multiple Internet sites. The two upgrades can be ordered independently – you can cache the content of one single busy website or run several different Internet sites with the default memory. You can get the most out of the Varnish platform if you’ve got a dedicated IP address and you can get one with your semi-dedicated package as well. Hepsia will grant you total control over the caching platform and, with no more than one click, you’ll be able to delete the cached content, to check a log or to restart an instance.
Varnish in VPS
We provide Varnish with all of the Hepsia-equipped Linux VPS packages, so in case you purchase a VPS with this Control Panel, you will be able to make the most of the data caching platform at no extra charge. The Varnish platform can use different amounts of memory for caching purposes based on the very package that you have selected during the signup procedure, but nevertheless, this amount won’t be less than several hundred MB. This is more than enough to optimize the work of a number of traffic-hungry websites, so the faster website browsing speeds and the lowered load on your virtual machine will be perceptible. The effect may not be evident right away, since Varnish will require a certain amount of time to cache the website content that users browse, but shortly after you enable it, you’ll observe its full potential. This platform will allow you to use a lower-end VPS server and to pay less money to get the exact same performance you would get with a higher-end machine without Varnish.
Varnish in Dedicated Hosting
When you need a more powerful hosting solution and you acquire one of the Linux dedicated servers hosting packages offered by our company, you’ll be able to use the Varnish caching platform to optimize the work of your Internet sites at no additional cost as long as the dedicated machine is ordered with our next-generation Hepsia hosting Control Panel. Its easy-to-work-with GUI will permit you to keep track of system processes, to clear the cached data or to restart any instance with one single click of the mouse. The smallest amount of memory that the platform can employ to cache content is 3 GB, which is more than enough for a large number of resource-absorbing Internet sites, so your server will be able to cope with an enormous system load while your website visitors are enjoying a smooth web browsing experience. As your machine will come with several dedicated IPs, you’ll be able to use Varnish’s maximum capacity.
