Varnish is a website accelerator platform, which caches data for the sake of faster response times. It is occasionally referred to as an HTTP reverse proxy too and it works between a web server and an Internet browser. When a visitor loads a certain page, its content is requested by the Internet browser, and then the web server processes this browser request and delivers the requested info. If Varnish is activated for a given website, it will cache the pages at the very first visit and if the user opens a cached page once again, the info will be delivered by the caching platform instead of the web server. The improved speed is a result of the considerably faster response time that the Varnish platform offers compared to any server software. Of course, this doesn’t mean that the site visitors will keep being served the exact same content over and over again, as any update on any of the pages is reflected in the content that Varnish saves in its system memory.
Varnish in Shared Hosting
If you host your Internet sites in a shared hosting account with us, you will be able to activate Varnish with a couple of clicks through your hosting Control Panel. The content caching platform is available as an upgrade with all our shared web hosting packages and you can select the number of the websites that will use it and the total storage space that will be used for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of memory and the number of instances and they are not linked directly to each other, so you can decide whether you need plenty of memory for a single large-scale website or less memory for several smaller ones. You can take advantage of the full potential of the Varnish platform in case the sites use a dedicated IP. With the Control Panel, you can swiftly start/reboot/delete an instance, clear the cached contents individually for each website that employs Varnish or check an elaborate system log file.
Varnish in Semi-dedicated Hosting
Varnish is included by default with all semi-dedicated hosting offered by us and you can use it for load balancing purposes. It is available in your Hepsia hosting Control Panel. The data caching platform comes with 64 megabytes of system memory for cached data storing purposes and you can use it with any site that you host in your semi-dedicated account. In case you are in need of more, you can increase the system memory allocation. The memory itself is available in increments of 32 MB in the Upgrades section of the Control Panel. The same section will permit you to activate more instances as well, in case you want to use the Varnish platform with multiple Internet sites. The two things can be added separately – you can cache the content of one single large-size website or use a number of sites with the default memory. You can get the most out of the Varnish caching platform if you have a dedicated IP and you can get one with your semi-dedicated server package as well. Hepsia will give you full control over the caching platform and, with no more than one single click of the mouse, you’ll be able to clear the cached data, to see a system log or to restart an instance.
Varnish in VPS Web Hosting
Varnish is included by default with each of the Linux VPS web hosting packages that we offer as long as the virtual server is ordered with the Hepsia hosting Control Panel, so you can optimize the performance of your sites with just a few mouse clicks. The more powerful the plan, the more memory Varnish will have at its disposal, but even with a lower-end package, the platform will be able to utilize several hundred MB, so even if you own a handful of sites, you will notice an enormous decrease in the overall server load and a much better site load speed. The Varnish platform will need to work for a while as the visitors browse the web pages and as soon as the website content has been cached, you’ll distinguish the effect. One of the advantages of employing Varnish is that a lower-end and less costly VPS plan will do the very same job as a more pricey one without the platform, so not only will your websites perform substantially better, but you will also save some money.
Varnish in Dedicated Servers Hosting
All dedicated servers hosting that are ordered with the in-house built Hepsia website hosting Control Panel come with Varnish, which is among the pre-installed platforms that you will get with the dedicated machine. The Varnish platform can be set up and managed with no effort from Hepsia’s intuitive interface and, with no more than one click of the mouse, you can check an in-depth system log, create or restart an instance, clear the cache for any site and much more. Shortly after you activate Varnish for a certain domain or subdomain, it will start caching the webpages requested by your website visitors and as soon as it has cached enough web content, you’ll witness a substantially better website performance and a lowered load on the machine. With Varnish-dedicated system memory starting at 3 gigabytes, you will be able to use the software platform for workload balancing purposes even if you run a lot of Internet sites on the dedicated machine.
