Varnish is a web accelerator tool, which has been gaining a lot in popularity in recent years, because it can increase the loading speed of any website, sometimes even by one hundred percent, based on the content. This tool is occasionally called an HTTP reverse proxy as well and is used to lower the overall load on the server and to boost the browsing speed for the website visitors. Anytime a visitor opens a page on a given website, the web browser request is taken care of by the web server and the requested info is delivered as a response. If Varnish is activated, it caches the pages that the website visitor opens and if any of them is accessed once more, it is fetched by Varnish and not by the web server directly. The performance increase comes from the fact that the accelerator processes the browser requests considerably quicker than any web server, which results in much faster browsing speeds for the users. In case any data is edited meanwhile, the cached web pages will also be ‘refreshed’ the next time someone accesses them.
Varnish in Cloud Hosting
You can make use of Varnish’s full potential and accelerate the load speed of your websites regardless of the cloud hosting package that you’ve selected and you can activate and set up the platform with a few mouse clicks using the easy-to-use GUI offered by our next-generation Hepsia Control Panel. During the process, you will be able to choose two different things – how many websites will use the Varnish caching platform, in other words – the number of instances, and how much info will be cached, i.e. the amount of system memory. The latter is offered in increments of 32 MB and is not tied to the number of instances, so you can use more instances with less memory and vice versa. If you’ve got plenty of content on a particular Internet site and you draw many site visitors, more memory will give you a better result. You may also consider employing a dedicated IP address for the websites that will use the Varnish caching platform. Hepsia will provide you with simple one-click buttons for stopping or restarting any instance, for deleting the cache associated with each website and for seeing comprehensive system logs.
Varnish in Semi-dedicated Hosting
The Varnish content caching platform is an essential part of the basic set of services that you will obtain when you choose to host your websites in a semi-dedicated server account. You can configure it for any of your sites via our leading-edge Hepsia hosting Control Panel. The default memory that the Varnish platform can use to cache content is 64 MB, but if you decide that you need more, you can upgrade this amount of memory 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 features are not bound to each other, you can use several instances with the default amount of memory or you can order more memory in increments of 32 MB and use all of it for one single site. The Varnish platform performs best if you get a dedicated IP address for the Internet sites that utilize its power. The Hepsia Control Panel will give you a simple way of rebooting any instance. In addition, you will be able to delete the cached data with just one single mouse click.
Varnish in VPS Web Hosting
We offer Varnish with all Hepsia-managed VPS web hosting services, so if you acquire a VPS with this hosting Control Panel, you’ll be able to make the most of the caching platform at no additional fee. Varnish can use different amounts of memory for data caching purposes based on the very VPS plan that you have chosen on the order page, but at any rate, this amount won’t be less than several hundred megabytes. This is quite enough to boost the performance of several different large sites, so the faster web page browsing speeds and the reduced load on the VPS will be noticeable. The effect may not be evident straight away, since Varnish will require some time to cache the website content that users access, but soon after you enable it, you will witness its full potential. This caching platform will permit you to use a less powerful Virtual Private Server and to pay less cash to get the exact same performance you would get with a more powerful machine without Varnish.
Varnish in Dedicated Servers Hosting
In case you order a dedicated server with the Hepsia Control Panel, you’ll get the Varnish caching platform at no additional cost and you’ll have full control over it via an amazingly simple-to-work-with GUI – you’ll be able to start, to remove or to restart an instance, to see a comprehensive system log, to delete the cached files associated with any site and much more. Varnish will have several GB of system memory at its disposal, so even if you manage frequently visited websites with a lot of visitors, you’ll notice the much faster website loading times and the decreased load on your dedicated machine. This will become a fact soon after you start using Varnish, as it will require some time to cache the website content that users access. You can get the most out of the platform’s capacity if the Internet sites that are using it also use a dedicated IP address, but since your dedicated server comes with a few IPs by default, you won’t need to pay anything on top of the monthly charge for the machine itself.
