Varnish is a web application accelerator platform, which caches content for the sake of quicker access. It’s sometimes referred to as an HTTP reverse proxy as well and it interacts between a web server and its users. When a website visitor loads a specific web page, its content is requested by the Internet browser, and then the server processes this request and delivers the needed data. If Varnish is enabled for a specific site, it will cache its pages at the very first visit and if the user accesses a cached page again, the data will be delivered by the caching platform and not by the server. The improved loading speed is an end result of the much faster response time that Varnish offers compared with any server software. Of course, this does not mean that the users will continue seeing the very same content over and over again, because any change on any of the web pages is reflected in the content that the Varnish platform stores in its memory.
Varnish in Shared Hosting
Varnish comes as an optional upgrade with each of our Linux shared service. You can add it to your hosting account via the Hepsia hosting Control Panel, which is offered with all shared hosting plans and you will get a rather simple-to-use graphical interface, which will grant you full control over the data caching platform. Using one-click fast-access buttons, you can restart or discontinue any of the instances, i.e. Varnish will no longer be activated for a certain Internet site. You can also check an exhaustive system log file or erase the cache associated with any of the sites. When you add Varnish to your shared hosting package, you’ll be able to choose the total amount of memory that will be at your disposal for data caching purposes and how many sites will use Varnish. You can always order more memory in increments of 32 megabytes and, for optimal performance, you can allocate a dedicated IP to the sites that will use Varnish. This will allow you to get the most out of your websites and to have numerous satisfied website users.
Varnish in Semi-dedicated Servers
Varnish is part of the standard service set that you’ll get in case you decide to host your websites in a semi-dedicated server account. You can enable it for any of your sites via our next-generation Hepsia Control Panel. The default system memory that the Varnish platform can use to cache content is 64 MB, but in case 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, i.e. the number of the Internet sites that can use this platform simultaneously. As these two features are not tied to each other, you can use a couple of Internet sites with the default memory or you can get more memory in increments of 32 MB and use all of it for one single site. Varnish works best if you set a dedicated IP address for the sites that utilize its power. Hepsia will give you a simple way of rebooting any instance. In addition, you’ll be able to clear the cached data with only one single click.
Varnish in VPS Servers
You can use Varnish with any of our VPS server plans at no additional charge, as the caching platform is pre-installed and is offered by default. The only precondition is that the Virtual Private Server must come with the Hepsia Control Panel, via which you will be able to set up Varnish for any of your Internet sites with only a few clicks. Each plan features a different amount of memory for content caching purposes, but you will have no less than several hundred MB, which is sufficient enough even for several traffic-intensive Internet sites. Shortly after you set up the Varnish platform, it will start caching the content that your visitors browse, so you will notice the substantially better website load times and the less load on your virtual server very soon. The Varnish caching platform will permit you to use a less high-priced Virtual Private Server, as you will not require that many resources to guarantee the proper operation of your sites even if you’ve got traffic-consuming websites with plenty of visitors. Optimum results are accomplished if the sites which use the Varnish caching platform also use a dedicated IP address.
Varnish in Dedicated Servers
When you need the most powerful web hosting solution and you obtain any of the dedicated servers that we offer, you’ll be able to use the Varnish data caching platform to enhance the overall performance of your Internet sites at no extra cost as long as the dedicated machine is ordered with our innovative Hepsia hosting Control Panel. Its simple-to-work-with interface will enable you to keep an eye on system processes, to delete the cached files or to restart any instance with a click. The smallest amount of memory that the caching platform can use to cache website content is 3 GB, which is more than enough for a vast selection of large Internet sites, so your dedicated server will be able to deal with a substantial system load while your website visitors are enjoying a smooth web browsing experience. As your server will include a number of dedicated IP addresses, you’ll be able to make use of Varnish’s maximum capacity.
