Varnish is a web application accelerator platform, which caches info for faster access. It’s occasionally called an HTTP reverse proxy too and it interacts between a web server and a web browser. When a visitor accesses a specific page, the content is requested by the Internet browser, and then the web server handles this browser request and returns the needed content. If Varnish is enabled for a certain site, it will cache its pages on the very first visit and in case the visitor visits a cached page once again, the content will be delivered by the caching platform instead of the web server. The increased load speed is a result of the significantly faster response time that Varnish offers as compared to any web server software. At the same time, this does not mean that the users will continue seeing the exact same content over and over again, as any change on any of the pages is reflected in the content that the Varnish platform keeps in its system memory.
Varnish in Cloud Hosting
In case you host your sites in a cloud hosting account with our company, you will be able to add Varnish with several clicks of the mouse from your hosting Control Panel. The data caching platform comes as an optional upgrade with all our hosting packages and you can select how many sites will use it and the maximum amount of system memory that will be used for the cached content. The two upgradeable features in the Upgrades section of the Control Panel are the number of instances and the amount of system memory and they’re not tied directly to each other, so you can choose whether you want lots of memory for one single large website or less memory for several smaller ones. You can take advantage of the full potential of the Varnish caching platform in case the websites use a dedicated IP. With the hosting Control Panel, you can effortlessly start/reboot/stop an instance, clear the cached content independently for each website which uses the Varnish platform or view an elaborate log.
Varnish in Semi-dedicated Hosting
The Varnish content caching platform is an essential part of the basic service set that you’ll receive in case you choose to host your sites under a semi-dedicated server account. You can activate it for any of your sites via our next-gen Hepsia Control Panel. The default amount of system memory that the Varnish platform can use to cache content is 64 MB, but if you decide that you want 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 sites that can use this platform at the same time. As these two things are not bound to each other, you can use a couple of sites with the default memory or you can add more memory in increments of 32 megabytes and use all of it for a single Internet site. The Varnish caching platform performs best if you set a dedicated IP for the Internet sites that utilize its power. The Hepsia Control Panel will provide you with a simple means of rebooting any instance. Also, you will be able to clear the cached files with only one single click.
Varnish in VPS Hosting
The Varnish caching platform comes by default with each of the Linux VPS hosting that we are offering as long as the Virtual Private Server is ordered with the Hepsia Control Panel, so you can boost the overall performance of your sites with just a couple of clicks of the mouse. The more powerful the plan, the more memory Varnish will have at its disposal, but even with a less powerful package, the platform will be able to utilize several hundred MB, so even if you’ve got a handful of Internet sites, you’ll notice an enormous reduction in the server load and a tremendously faster page loading speed. The Varnish platform will have to work for a little while as the users browse the web pages and as soon as the content has been cached, you will distinguish the effects. One of the pluses of using Varnish is that a less powerful and less pricey VPS package will accomplish the very same job as a more costly one without the platform, so not only will your sites perform considerably better, but you will also save some cash.
Varnish in Dedicated Web Hosting
You can employ Varnish to accelerate the speed of any website that’s hosted on a dedicated server from our company if the Hepsia Control Panel is pre-installed on the machine. Not only will you get the caching platform ready to be used at no additional fee, but you will also exert full control over it via Hepsia’s simple-to-work-with interface. It will take just a click to start or shut down an instance or to clear the cached files for any Internet site that’s using Varnish and in case you’re more trained, you can also see the platform’s logs. Varnish comes with no less than 3 gigabytes of system memory for content caching purposes, so even if you run a large number of sites on your machine and they all use the Varnish caching platform, the difference in their performance will be evident. You will simply have to wait for a while till Varnish caches whatever webpages the site visitors open on their end. The Varnish platform performs best if the websites use a dedicated IP address, but since our dedicated servers come with 3 free-of-cost IP addresses, you’ll have all that you need.
