Varnish is a web application accelerator platform, which caches information for faster response times. It’s sometimes referred to as an HTTP reverse proxy as well and it works between a web server and an Internet browser. When a visitor opens a particular page, its content is requested by the Internet browser, and then the server processes this browser request and delivers the necessary info. If Varnish is activated for a given site, it will cache its pages at the very first request and if the user opens a cached page again, the data will be delivered by the caching platform instead of the server. The boosted loading speed is an end result of the considerably faster response time that Varnish offers compared with any web server software. Of course, this doesn’t mean that the site visitors will continue being served the same content over and over again, because any change on any of the pages is reflected in the content that the Varnish platform saves in its system memory.
Varnish in Website Hosting
You can use Varnish’s potential and accelerate your websites’ loading speed regardless of the website hosting package that you have chosen and you can enable and configure the content caching platform with several mouse clicks from the intuitive graphical interface offered by our next-gen Hepsia hosting Control Panel. In the meantime, you will be able to choose two different things – how many websites will use Varnish, i.e. the number of instances, and how much content will be cached, i.e. the amount of memory. The latter is available in increments of 32 MB and is not bound to the number of instances, so you can add more instances and less memory and the other way around. If you have lots of content on a particular site and you win numerous website visitors, more memory will guarantee you better results. You may also consider using a dedicated IP address for the Internet sites that will use the Varnish platform. Hepsia will offer you easy 1-click controls for switching off or restarting any instance, for erasing the cache associated with any Internet site and for seeing exhaustive system logs.
Varnish in Semi-dedicated Hosting
Varnish is a feature, which comes as standard with all Linux semi-dedicated hosting packages that we offer and you can use it for load distribution purposes. It is available in your Hepsia hosting Control Panel. The content caching platform comes with 64 MB of system memory for cached data storing purposes and you can use it with any website that you host in the semi-dedicated account. If you need more, you can increase the system memory allocation. The memory itself is offered in increments of 32 megabytes through the Control Panel’s Upgrades section. The very same section will enable you to enable more instances as well, if you want to use the Varnish platform with multiple websites. The two upgrades can be added separately – you can cache the content of one single resource-consuming site or run several websites with the default memory allocation. You can take full advantage of the Varnish caching platform if you have a dedicated IP address and you can order one with your semi-dedicated plan as well. Hepsia will grant you full control over the platform and, with no more than a click, you will be able to clear the cached files, to view a log or to restart an instance.
Varnish in VPS Hosting
The Varnish caching platform comes by default with all Linux VPS hosting packages offered by us as long as the VPS server is ordered with the Hepsia hosting Control Panel, so you can optimize the performance of your websites with only a few mouse clicks. The more powerful the plan, the more memory Varnish will have at its disposal, but even with a low-end plan, the platform will be able to utilize several hundred megabytes, so even if you manage a number of Internet sites, you will notice an enormous reduction in the server load and a considerably better web page load speed. The Varnish caching platform will have to work for a little while while the users navigate the site and once the site content has been cached, you will perceive the effects. One of the advantages of using Varnish is that a less powerful and less pricey VPS plan will do the very same job as a more expensive one without the platform, so not only will your Internet sites work much better, but you’ll also spare some money.
Varnish in Dedicated Web Hosting
In case you order a dedicated server with the Hepsia hosting Control Panel, you will get the Varnish data caching platform at no additional charge and you’ll have full control over it via a really user-friendly graphical interface – you’ll be able to start, to discontinue or to restart an instance, to check a detailed log, to delete the cached content for any site and much, much more. The Varnish platform will have several GB of memory at its disposal, so even if you run large Internet sites with a large number of visitors, you’ll notice the substantially better page load times and the reduced load on the dedicated machine. This will become a fact shortly after you begin using the Varnish platform, since it will require a certain amount of time to cache the web pages that users browse. You can get the most out of the platform’s capabilities if the Internet sites that are using it use also a dedicated IP, but considering the fact that your server comes with a couple of IP addresses by default, you will not need to pay anything on top of your monthly fee for the machine itself.
