Varnish is a web application accelerator platform, which caches data for quicker access. It’s occasionally referred to as a caching HTTP reverse proxy as well and it works between a web server and its users. When a website visitor accesses a certain web page, the content is requested by the browser, and then the web server processes this request and returns the needed information. If Varnish is enabled for a given website, it will cache the pages at the very first request and if the user opens a cached page once again, the data will be delivered by the accelerator platform and not by the web server. The boosted load speed is an end result of the considerably faster response speed that Varnish offers as compared with any web server software. At the same time, this does not mean that the users will keep seeing the same content again and again, since any update on any of the pages is reflected in the content that Varnish stores in its memory.
Varnish in Cloud Web Hosting
In case you host your Internet sites under a cloud web hosting
account with our company, you will be able to activate Varnish with several mouse clicks through your hosting Control Panel. The data caching platform comes as an upgrade with all our shared hosting packages and you can select the number of the sites that will use it and the maximum storage space that will be used for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of memory and the number of instances and they aren’t linked directly to each other, so you can decide if you want plenty of memory for one large-scale site or less memory for multiple smaller ones. You can make use of the full potential of the Varnish caching platform if the websites use a dedicated IP address. With the hosting Control Panel, you can effortlessly start/restart/discontinue an instance, delete the cached data individually for each website which employs the Varnish platform or view an in-depth log.
Varnish in Semi-dedicated Servers
Varnish is an essential part of the default set of services that you will acquire in case you choose to host your websites in a semi-dedicated server
account. You can configure it for any of your sites through our innovative Hepsia Control Panel. The default amount of system memory that the Varnish caching platform can use to cache content is 64 MB, but in case you decide that you want more, you can upgrade this amount from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the websites that can use this caching platform simultaneously. Since these two things aren’t tied to each other, you can use several Internet sites with the default memory or you can get more memory in increments of 32 megabytes and use all of it for a single web site. Varnish works best if you use a dedicated IP address for the websites that utilize its power. The Hepsia Control Panel will offer you an easy means of restarting any instance. Also, you will be able to clear the cached data with just one single click.
Varnish in VPS Servers
We provide Varnish with all Hepsia-managed VPS servers
, so in case you acquire a server with this web hosting Control Panel, you will be able to take full advantage of the caching platform at no additional fee. The Varnish platform can use different amounts of system memory for data caching purposes based on the particular setup that you’ve chosen during the subscription process, but at any rate, this amount will not be less than several hundred MB. This is quite enough to improve the work of several traffic-heavy websites, so the better website browsing speeds and the decreased load on the VPS will be perceptible. The effect may not be distinguishable straight away, as Varnish will need some time to cache the content that users request, but soon after you set it up, you will feel its full potential. This platform will allow you to use a lower-end server and to give less money to get the very same performance you would get with a more powerful machine without Varnish.
Varnish in Dedicated Servers
You can employ Varnish in order to speed up any website that is hosted on a dedicated server
with us when the Hepsia hosting Control Panel is pre-installed on the machine. Not only will you get the content caching platform ready for use at no extra charge, but you will also exert full control over it through the Hepsia Control Panel’s intuitive graphical interface. It will take only one click to start or terminate an instance or to delete the cached data for any website that’s using Varnish and if you are more practiced, you can also view the platform’s logs. Varnish comes with at least 3 GB of system memory for site content caching purposes, so even if you host numerous Internet sites on your dedicated machine and they all use the caching platform, the difference in their performance will be observable. You’ll only need to wait for a while till Varnish caches whatever web pages the website visitors browse on their end. The platform performs best if the sites use a dedicated IP, but since our dedicated servers come with three free-of-charge IPs, you will have everything you need.
