What is cloud hosting? If you run a website, there are two types of cloud computing you might have found out about: cloud servers and cloud-based content delivery systems (CDNs). What exactly are they, just how do they work, and what benefits do they bring? So what’s a cloud server like in practice?
It’s relatively easy to join up to cloud services and find out for yourself. After the server’s created, you can configure it in the most common way (as being a physical server) with software like WHM and cPanel-or nevertheless, you wish. If you decide you no want your server you can destroy it in the same way easily much longer, and you merely purchase what you’ve used (an hourly rate for the server and a per GB rate for the bandwidth).
It’s extremely simple to use. Despite having only previous experience of shared hosting and no previous experience of WHM whatsoever, I had this website up and running on a Storm cloud server in a couple of hours. Photos: Liquid Web’s Storm on Demand gives you to create a cloud server in a matter of minutes, simply by ticking a few boxes.
Every aspect of the service is pay-as-you-go. It’s user friendly even though you have little if any experience of setting up or handling dedicated servers. Cloud servers or digital servers? How do cloud servers work? The important thing to keep in mind is that “cloud server” is actually a marketing term rather than a technical explanation or description.
Hosting products described as “cloud servers” are generally virtual slices of large, physical servers running what’s called virtualization software(the most common types being VMware and Xen hypervisor for Linux and Microsoft Hyper-V for Windows). In other words, they may be effectively “virtual servers” (completely independent digital machines) operating on a genuine, physical server. How is that different from shared enviroment?
The digital servers are essentially unbiased of one another (though they do use the same processors and memory), so you are not in danger from other people’s applications or websites. Your site can benefit hugely from cloud computing even though you don’t want to migrate it to a cloud server. Information-rich sites such as this one, with a lot of static content, typically use over 90 percent of their bandwidth portion up images (and other media) and CSS data files that probably don’t differ from one month to another.
With traffic break up equally between Europe, America, and Asia, there is no easy way to decide where to find your main server: wherever you choose, some users shall benefit and more will lose out. But putting the static content on the content delivery network (CDN) , dispersed across the cloud, will benefit everyone. Speaking Simply, a CDN makes multiple copies of your static data files and stores them at key “edge locations” round the world so that different users in different continents get whichever documents are closest (and therefore quickest to download). How do you setup a CDN in practice? Suppose you want to increase your website by moving all your images on to a CDN.

You can join a pay-as-go CDN in just a matter of minutes (Amazon’s Cloudfront and Rackspace Cloud Files are two popular, instant options, but there are plenty of others). You can either use this address explicitly (referring to it straight in your IMG tags) or (more sensibly) refer to it through a CNAME (effectively a DNS alias) predicated on your own domain name.
When people down load your webpages, the images are no longer pulled from your primary server but in one of the edge locations across the world-ideally one that’s geographically near to where they happen to be. So how exactly does it work behind the moments? You can find out if you execute a DNS lookup for whatever domain name you’re using for your CDN. Of an individual IP address Instead, you’ll find the name resolves to different IP addresses in various parts of the world.
