Varnish is a website accelerator platform, which caches info for the sake of faster access. It is sometimes referred to as an HTTP reverse proxy too and it works between a web server and a browser. When a site visitor opens a given page, the content is requested by the browser, and then the server processes this browser request and delivers the required information. If Varnish is enabled for a certain site, it will cache the pages on the very first request and if the visitor accesses a cached page once more, the data will be delivered by the accelerator platform and not by the server. The boosted speed is a result of the much faster response time that the Varnish platform offers as compared to any web server software. At the same time, this does not mean that the website visitors will keep seeing the exact same content over and over again, as any modification on any of the pages is reflected in the content that the Varnish platform caches in its system memory.

Varnish in Cloud Web Hosting

If you host your websites in a cloud web hosting account with our company, you will be able to activate Varnish with a couple of mouse clicks via your hosting Control Panel. The platform is offered as an upgrade with all our plans and you can select how many websites will use it and the maximum amount of system memory that will be available for the cached data. The two upgradeable features in the Upgrades section of the Control Panel are the amount of system memory and the number of instances and they are not directly tied to each other, so you can decide if you want lots of memory for one single large-scale site or less memory for multiple smaller ones. You can make use of the full potential of the Varnish platform if the sites use a dedicated IP. With the hosting Control Panel, you can quickly start/reboot/stop an instance, delete the cached files individually for each site which uses the Varnish platform or view a detailed log.

Varnish in Semi-dedicated Servers

The Varnish content caching platform is an essential part of the standard service set that you will receive if you choose to host your websites in a semi-dedicated server account. You can enable it for any of your websites via our next-generation Hepsia hosting Control Panel. The default system memory that the Varnish platform can use to cache content is 64 megabytes, but if you decide that you need more, you can upgrade this amount of memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this platform at the same time. As these two features are not tied to each other, you can use a few Internet sites with the default amount of memory or you can add more memory in increments of 32 MB and use all of it for a single website. The Varnish caching platform performs best if you assign a dedicated IP address to the sites that utilize its power. Hepsia will give you a simple way of rebooting any instance. What’s more, you’ll be able to clear the cached files with just one click of the mouse.

Varnish in VPS Servers

Varnish is included by default with each of the Linux VPS servers that we are offering as long as the virtual server is ordered with the Hepsia hosting Control Panel, so you can improve the performance of your sites with only a couple of clicks of the mouse. The more powerful the package, the more system memory Varnish will have at its disposal, but even with a lower-end plan, the platform will be able to utilize several hundred MB, so even if you manage a number of sites, you’ll notice an enormous reduction in the server load and a significantly better webpage load speed. The platform will need to work for a while as the visitors navigate the website and once the site content has been cached, you’ll perceive the effects. One of the pros of employing Varnish is that a lower-end and less costly Virtual Private Server package will accomplish the exact same job as a more high-priced one without the caching platform, so not only will your Internet sites work considerably better, but you’ll also save a certain amount of money.

Varnish in Dedicated Servers

All Linux dedicated servers which are ordered with the custom-developed Hepsia website hosting Control Panel feature Varnish, which is one of the pre-installed platforms that you’ll get with the machine. The Varnish caching platform can be enabled and administered without any effort from Hepsia’s easy-to-navigate interface and, with no more than one click, you can check an elaborate system log, create or reboot an instance, clear the cached files associated with any site and much, much more. Shortly after you activate the Varnish platform for a certain domain or sub-domain, it will begin caching the web pages browsed by your website visitors and once it has cached enough web content, you’ll perceive a substantially better website performance and a reduced load on your server. With Varnish-dedicated virtual memory starting at three gigabytes, you will be able to use the software platform for load balancing purposes even if you host a vast number of websites on your machine.
