Varnish is a web app accelerator platform, which caches content for the sake of quicker access. It’s sometimes called a caching HTTP reverse proxy too and it interacts between a web server and a browser. When a visitor accesses a certain page, its content is requested by the Internet browser, and then the server handles this request and delivers the requested information. If Varnish is activated for a specific site, it will cache the pages on the very first visit and if the visitor accesses a cached page once again, the content will be delivered by the caching platform and not by the web server. The improved loading speed is a result of the much faster response time that the Varnish platform offers compared with any web server software. At the same time, this doesn’t mean that the website visitors will keep seeing the very same content again and again, because any update on any of the pages is reflected in the content that Varnish caches in its system memory.
Varnish in Cloud Hosting
In case you host your Internet sites in a cloud hosting account with our company, you’ll be able to activate Varnish with a couple of mouse clicks from your Control Panel. The platform is available as an upgrade with all our shared web hosting plans and you can select how many websites will use it and the total storage space that will be used for the cached content. The two upgradeable features in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they’re not directly tied to each other, so you can choose whether you want plenty of memory for one single large site or less memory for several smaller ones. You can use the full potential of the Varnish platform in case the sites use a dedicated IP address. With the hosting Control Panel, you can swiftly start/restart/remove an instance, delete the cached files independently for each site that employs Varnish or view a comprehensive log file.
Varnish in Semi-dedicated Servers
Varnish is offered by default with all Linux semi-dedicated hosting plans that we offer and you can use it for workload distribution purposes. It’s available in your Hepsia Control Panel. The Varnish content caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can use it with any website that you host in your account. In case you are in need of more than that, you can increase the memory quota. The memory itself is available in increments of 32 MB in the Control Panel’s Upgrades section. The very same section will permit you to enable more instances too, if you would like to use Varnish with multiple Internet sites. The two things can be added independently – you can cache the content of one traffic-heavy site or run several different websites with the default memory allowance. You can take full advantage of the Varnish caching platform in case you have a dedicated IP and you can order one with your semi-dedicated package as well. Hepsia will grant you total control over the platform and, with no more than one mouse click, you will be able to clear the cached data, to see a system log file or to reboot an instance.
Varnish in VPS Servers
You can take advantage of Varnish with each of our VPS server plans at no additional fee, as the platform is pre-installed and is available by default. The only condition is that the Virtual Private Server must come with the Hepsia hosting Control Panel, through which you’ll be able to activate Varnish for any of your websites with just a couple of mouse clicks. Each Virtual Private Server plan features a different amount of memory for caching purposes, but you’ll get no less than several hundred megabytes, which is quite sufficient even for several traffic-heavy websites. Shortly after you enable the Varnish platform, it’ll start caching the content that your site visitors request, so you’ll notice the significantly better Internet site loading times and the decreased load on your virtual server in no time. The platform will permit you to use a less pricey VPS server, as you will not require that much power to warrant the proper operation of your websites even if you have busy Internet sites with many visitors. Optimum results are accomplished if the Internet sites which use Varnish also use a dedicated IP.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia Control Panel, you’ll acquire the Varnish content caching platform at no additional charge and you will have total control over it via a very simple-to-navigate interface – you will be able to start, to delete or to restart an instance, to browse an in-depth log, to clear the cached content for any Internet site and much more. The Varnish platform will have several GB of system memory at its disposal, so even if you host traffic-intensive sites with plenty of visitors, you will notice the significantly better site load times and the less load on the dedicated server. This will happen soon after you start using Varnish, since it will need some time to cache the website content that people access. You can get the most out of the platform’s capability if the websites that are using it use also a dedicated IP, but considering the fact that your dedicated server includes a few IP addresses by default, you will not need to pay anything on top of the monthly fee for the machine itself.
