Varnish is a web application accelerator, which has been gaining a lot in popularity lately, as it can increase the load speed of any Internet site, at times even by 100%, based on the content. This tool is sometimes called an HTTP reverse proxy too and is used to reduce the overall load on the physical server and to enhance the browsing speed for the site visitors. Whenever a visitor loads a page on a given Internet site, the browser request is processed by the web server and the requested content is sent as a reply. If the Varnish accelerator is activated, it caches the web pages that the site visitor browses and in case any of them is opened once again, it’s served by Varnish and not by the server directly. The performance improvement comes from the fact that the accelerator handles the web requests substantially faster than any web server, which leads to much faster browsing speeds for the website visitors. If any data is changed in the meantime, the cached webpages will also be updated the next time someone opens them.
Varnish in Shared Website Hosting
If you host your Internet sites under a shared website hosting account with us, you’ll be able to activate Varnish with a few clicks from your Control Panel. The data caching platform is available as an upgrade with all our shared hosting plans and you can choose the number of the websites that will use it and the total amount of system memory that will be available for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they aren’t directly linked to each other, so you can decide whether you want a lot of memory for a single large website or less memory for several smaller ones. You can take advantage of the full potential of Varnish in case the sites use a dedicated IP address. With the Control Panel, you can quickly start/restart/terminate an instance, clear the cached contents independently for each website which employs the Varnish platform or see an elaborate log.
Varnish in Semi-dedicated Servers
The Varnish data caching platform is an essential part of the basic set of services that you will get when you decide to host your websites in a semi-dedicated server account. You can enable it for any of your Internet sites via our next-generation Hepsia Control Panel. The default amount of memory that the Varnish caching platform can use to cache content 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 sites that can use this caching platform simultaneously. As these two features aren’t bound 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 one single site. The Varnish platform performs best if you use a dedicated IP address for the Internet sites that utilize its power. The Hepsia Control Panel will offer you a simple means of rebooting any instance. On top of that, you will be able to delete the cached contents with just one mouse click.
Varnish in VPS Servers
The Varnish content caching platform comes by default with all VPS web hosting plans that we’re offering as long as the VPS server is ordered with the Hepsia Control Panel, so you can boost the performance of your sites with just a couple of mouse clicks. The more powerful the package, the more system memory will be available to Varnish, but even with a lower-end package, the caching platform will be able to utilize several hundred megabytes, so even if you’ve got a handful of websites, you will notice a noticeable decrease in the server load and a significantly faster website load speed. The platform will have to work for a little while as the users browse the site and as soon as the content has been cached, you will distinguish the effects. One of the pluses of employing Varnish is that a less powerful and less expensive Virtual Private Server plan will do the very same job as a more costly one without the caching platform, so not only will your sites work significantly better, but you will also save a certain amount of money.
Varnish in Dedicated Servers
You can use Varnish in order to accelerate the speed of any website that’s hosted on a dedicated server with our company when the Hepsia Control Panel is installed on the machine. Not only will you get the platform ready to be used at no additional cost, but you will also exert full control over it through Hepsia’s easy-to-use interface. It’ll take just one click to start or delete an instance or to clear the cached files associated with any Internet site that is using Varnish and in case you’re more competent, you can also see the platform’s system logs. Varnish comes with no less than 3 gigabytes of memory for website content caching purposes, so even in case you host many Internet sites on your dedicated machine and they all use the Varnish caching platform, the difference in their overall performance will be evident. You’ll just have to wait for a little while till Varnish caches whatever webpages the site visitors load on their end. The platform performs best when the websites use a dedicated IP, but owing to the fact that our dedicated servers include 3 cost-free IPs, you’ll have all that you need.
