Varnish is a web application accelerator platform, which caches content for the sake of quicker response times. It is occasionally referred to as a caching HTTP reverse proxy as well and it interacts between a web server and a web browser. When a visitor accesses a particular webpage, the content is requested by the web browser, and then the web server processes this browser request and delivers the required data. If Varnish is enabled for a certain site, it will cache the pages on the very first request and in case the visitor opens a cached page again, the content will be delivered by the caching platform instead of the server. The accelerated loading speed is a result of the substantially faster response time that the Varnish platform offers as compared to any server software. Of course, this doesn’t mean that the users will continue being served the same content over and over again, as any change on any of the web pages is reflected in the content that the Varnish platform saves in its system memory.
Varnish in Shared Hosting
Varnish is offered as an optional upgrade with each Linux shared hosting and if you’d like to use it, you can add it to your website hosting account via the Upgrades menu in your Hepsia Control Panel. There’re two different features that can be upgraded – the number of instances and the memory. The first one refers to the number of the Internet sites that you want to employ Varnish for and the second one, which comes in increments of 32 megabytes, displays the total amount of data that the platform can cache at any particular moment. The Hepsia Control Panel’s easy-to-work-with GUI will allow you to deactivate or to reboot any instance, to see comprehensive logs or to clear the platform’s cache with just a click. For optimum results, you can use a dedicated IP for the websites that will use the caching platform. With Varnish, your Internet site will open substantially faster, which means more satisfied users and prospective clients.
Varnish in Semi-dedicated Hosting
The Varnish content caching platform is included in the basic set of services that you will get in case you choose to host your Internet sites in a semi-dedicated server account. You can activate it for any of your sites via our innovative Hepsia Control Panel. The default amount of system memory that Varnish can use to cache data is 64 MB, but in case you decide that you need more, you can upgrade this 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 simultaneously. Since these two features aren’t tied to each other, you can use several instances with the default amount of memory or you can get more memory in increments of 32 MB and use all of it for one single site. The Varnish platform works best if you get a dedicated IP for the Internet sites that utilize its power. Hepsia will provide you with an easy way of restarting any instance. Also, you will be able to clear the cached content with only one click.
Varnish in VPS
You can use Varnish with all our virtual private server plans at no extra cost, as the content caching platform is pre-installed and is available by default. The only prerequisite is that the VPS server must come with the Hepsia Control Panel, via which you’ll be able to set up Varnish for any of your websites with just a few mouse clicks. Each Virtual Private Server package includes a different amount of memory for data caching purposes, but you will have at least several hundred MB, which is sufficient even for several resource-heavy Internet sites. Shortly after you set up the Varnish platform, it’ll begin caching the content that your site visitors access, so you’ll notice the significantly better web page loading times and the reduced load on your VPS very soon. The Varnish platform will allow you to use a less expensive Virtual Private Server, as you won’t require that many resources to warrant the correct operation of your sites even if you have larger websites with multiple visitors. Optimal results are achieved if the sites that use Varnish also use a dedicated IP.
Varnish in Dedicated Hosting
You can use Varnish in order to accelerate the load speed of any website that is hosted on a dedicated server from our company when the Hepsia Control Panel is installed on the machine. Not only will you get the caching platform ready for use at no extra cost, but you’ll also exert total control over it through Hepsia’s easy-to-work-with GUI. It will take only one single mouse click to start or remove an instance or to clear the cached files for any Internet site that is using the Varnish platform and if you are more sophisticated, you can also browse the platform’s logs. Varnish comes with no less than 3 GB of virtual memory for content caching purposes, so even if you host numerous Internet sites on your machine and they all use the caching platform, the difference in their overall performance will be evident. You will simply have to wait for a little while till Varnish caches whatever content the visitors open on their end. The Varnish platform works best when the Internet sites use a dedicated IP address, but owing to the fact that our servers come with three cost-free IP addresses, you will have everything you need.
