Varnish is a web accelerator platform, which caches content for the sake of quicker response times. It’s sometimes referred to as a caching HTTP reverse proxy as well and it interacts between a web server and a web browser. When a website visitor loads a certain page, its content is requested by the browser, and then the web server processes this browser request and delivers the needed info. If Varnish is activated for a specific site, it will cache its pages on the first visit and if the user opens a cached page once more, the data will be delivered by the caching platform and not by the server. The accelerated speed is an end result of the significantly faster response time that the Varnish platform offers compared with any web server software. At the same time, this does not mean that the visitors will continue seeing the very same content again and again, as any update on any of the pages is reflected in the content that Varnish stores in its memory.
Varnish in Cloud Hosting
Varnish is offered as an optional upgrade with each cloud hosting and if you would like to use it, you can add it to your hosting account via the Upgrades menu in your Hepsia hosting Control Panel. There are two different things that can be upgraded – the instances and the system memory. The first one depends on the number of the sites that you would like to employ Varnish for, whereas the second, which comes in increments of 32 megabytes, pertains to the total amount of data that the data caching platform can store at any given time. Hepsia’s intuitive graphical interface will allow you to stop or to reboot any instance, to check elaborate logs or to clear the platform’s cache with just click of the mouse. For best results, you can use a dedicated IP for the websites that will use the platform. With Varnish, your site will open considerably faster, meaning more happy site visitors and potential clients.
Varnish in Semi-dedicated Servers
All our semi-dedicated servers include Varnish by default, so you can take full advantage of the web accelerator and accelerate any website that you host on our semi-dedicated servers. You will get 64 megabytes of memory exclusively for Varnish at no extra fee and you can activate an instance with no more than a couple of clicks through the Hepsia Control Panel, which comes with the semi-dedicated plans. In case you want more memory, the latter is offered in increments of 32 megabytes in the Upgrades section of the Control Panel and it will be available to you momentarily. You can also order more instances as an upgrade, so you can decide if lots of data will be cached for a single site or whether the memory will be used by multiple Internet sites. Hepsia will permit you to restart or to disable any instance, to see the system log file associated with it or to clear the cached files using single-click controls. To get the most out of the Varnish accelerator, you can assign a dedicated IP address to the websites which will employ it.
Varnish in VPS Servers
We provide Varnish with all Hepsia-equipped VPS servers, so in case you acquire a server with this web hosting Control Panel, you will be able to take advantage of the content caching platform at no additional charge. Varnish can use different amounts of system memory for caching purposes based on the specific setup that you’ve chosen during the server order process, but nevertheless, this amount won’t be less than several hundred megabytes. This is quite enough to boost the work of several different resource-requiring websites, so the better site loading speeds and the decreased load on your Virtual Private Server will be discernible. The effect may not be apparent immediately, since Varnish will need some time to cache the site content that people access, but soon after you set it up, you’ll feel its full capacity. This platform will allow you to use a lower-end server and to pay less cash to get the exact same performance you’d get with a more powerful virtual machine without Varnish.
Varnish in Dedicated Servers
You can use Varnish to optimize the loading speed of any site that is hosted on a dedicated server from our company if the Hepsia hosting Control Panel is pre-installed on it. Not only will you get the caching platform ready to be used at no additional charge, but you’ll also exert full control over it via Hepsia’s simple-to-navigate graphical interface. It’ll take only one click of the mouse to start or terminate an instance or to clear the cached content for any site that is using the Varnish platform and if you are more sophisticated, you can also browse the platform’s logs. Varnish comes with no less than 3 gigabytes of memory for content caching purposes, so even in case you run lots of websites on your server and they all use the platform, the difference in their overall performance will be evident. You’ll only have to wait for a while until Varnish caches whatever pages the site visitors open on their end. The platform performs best when the sites use a dedicated IP address, but considering the fact that our dedicated servers come with three cost-free IP addresses, you’ll have everything you need.
