Varnish is a web accelerator, which has been gaining a lot in popularity in recent years, because it can increase the loading speed of any website, at times even by 100%, depending on the content. This tool is sometimes called a caching HTTP reverse proxy too and is used to lower the overall load on the server and to improve the access speed for the site visitors. Anytime a visitor opens a page on a certain Internet site, the browser request is handled by the web server and the requested information is returned as a reply. If Varnish is activated, it caches the pages that the site visitor opens and in case any of them is opened again, it is served by Varnish and not by the server directly. The performance increase is due to the fact that the accelerator processes the web requests considerably quicker than any web server, which leads to much faster browsing speeds for the visitors. In case any data is edited meanwhile, the cached pages will also be updated the next time somebody accesses them.
Varnish in Cloud Web Hosting
Varnish is offered as an optional upgrade with all our Linux cloud web hosting
. You can add it to your account through the Hepsia hosting Control Panel, which comes with all shared packages and you will get a quite easy-to-use GUI, which will give you full control over the data caching platform. Using one-click quick-access controls, you can reboot or discontinue any of the instances, i.e. Varnish will no longer be activated for a certain website. You can also see an in-depth log file or clear the cache for any of the sites. When you add Varnish to your shared hosting package, you’ll be able to select the total amount of system memory that will be at your disposal for content caching purposes and how many websites will use Varnish. You can always get more memory in increments of 32 MB and, for optimum 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 numerous happy site users.
Varnish in Semi-dedicated Hosting
The Varnish platform is part of the basic set of services that you will receive when you choose to host your Internet sites in a semi-dedicated server
account. You can configure it for any of your websites through our innovative Hepsia hosting 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 amount from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this caching platform at the same time. As these two things aren’t linked to each other, you can use a couple of websites with the default amount of memory or you can order more memory in increments of 32 megabytes and use all of it for a single site. The Varnish caching platform works best when you use a dedicated IP address for the Internet sites that utilize its power. Hepsia will give you a simple means of rebooting any instance. Also, you will be able to clear the cached content with only one click of the mouse.
Varnish in Dedicated Web Hosting
All Linux dedicated web hosting
that are ordered with the tailor-made Hepsia hosting Control Panel include Varnish, which is one of the pre-installed software platforms that you will get with the dedicated machine. The Varnish content caching platform can be enabled and administered without any effort through Hepsia’s intuitive GUI and, with no more than one single click, you can browse an in-depth system log, add or restart an instance, delete the cached data associated with any website and much, much more. Soon after you set up the Varnish platform for a given domain or subdomain, it will start caching the web pages accessed by your website visitors and once it has cached enough content, you’ll perceive a significantly better site performance and a decreased load on the dedicated server. With Varnish-dedicated memory starting at 3 GB, you’ll be able to use the software platform for workload distribution purposes even if you run a lot of sites on the server.
