Processors in dedicated servers are entirely devoted to the host website or application. Unless all of the processing power is used at once (which is highly unlikely), they do not need to queue requests. This makes dedicated servers an excellent choice for companies with CPU intensive load balancing functions. In a cloud environment, processor cores require management to keep performance from degrading. The current generation of hypervisors cannot manage requests without an added level of latency.
Speaking of storage, we've discovered that cloud hosts typically offer hard drives or solid-state drives that range between 100GB and 200GB in size. That said, you'll occasionally discover a web host that boasts unlimited storage. (Again, the usual caveats apply with regards to "unlimited" anything.) Solid-state drives are typically faster than their hard-drive-based counterparts, but are typically smaller in terms of storage capacity. If you're looking for sheer volume, a traditional hard drive is the way to go.
While shared, VPS, and dedicated server hosting packages rely on one physical server at a time, cloud hosting enables an unlimited number of servers to act as a unified system. With so many resources at your disposal, cloud hosting introduces a greater level of scalability, availability, and performance. The added flexibility of adding or removing resources means many hosting providers bill customers monthly for exactly the resources used.

If you're looking for a real-time example of cloud hosting, what better example can someone give other than Google itself? The king of search engines has got its resources spread over hundreds of servers on the cloud, no wonder you've never seen Google.com facing any downtimes over past decade or so (I don't remember seeing it down – planned maintenance of services like AdSense and AdWords are a different affair altogether!)

At Hostinger , we use cloudlinux with LVE containers. Each account gets a dedicated container and is served from there. Each container has resource boundaries to make sure the host stays healthy at all times (even if, one of the accounts is under a DDoS attack). In case the host needs to be put down, the account with its container can be easily migrated to a different host, to avoid unnecessary downtime. Our shared hosting accounts share hosts between several customers, whereas our cloud hosting clients are served solely from the host, meaning that only their accounts are put in the whole host.

A hybrid server model also gives companies greater data security. For example, with a SysGen hybrid model, clients can back up their data to an onsite server as well as a cloud solution. SysGen’s backup solution partner, Datto, introduces next-gen backup, disaster recovery, and business continuity solutions. Read more about backup solutions in our blog post, “Five key questions to ask about your backup solution”.
Your Virtual Private Server is automatically provisioned with your choice of CentOS or Ubuntu, and a firewall. No more software overhead, no more slow servers. That means that you have total control and freedom to customize, optimize, and set up your VPS server to your exact needs. Whether you want Apache, NGINX, PHP, MySQL, custom services, or anything else, you're able to do so with our Cloud VPS servers.
You are responsible for your backups and web content. We create our own weekly backups of Cloud servers, and we can restore your web, email and database content from those per your request. However, this is NOT a procedure you should rely on to keep copies of your content safe; we recommend you make your own backups. You can take a backup from your cPanel.
At the end of the day, you need a reliable VPS that stays online, doesn't crash, and isn't slow. Our next generation VPS platform is highly available. We achieve this through 2X hardware duplication and 3X data replication. That means that even if something happened to your node, or even our infrastructure, we automatically switch to a backup. Spend less time fighting your web hosting company, and more time building your projects.
IT departments don’t need to invest in in-house server hardware. And customers don’t need to pay for up front for extra storage or processing capacity that they don’t use. Cloud hosting is more quickly scalable than traditional hosting. If an application or website receives more or less traffic, the cloud servers scale up and down automatically. With cloud hosting, there’s no need to manually add or remove server space as there is in shared hosting.
Shared Server Hosting is the most common and affordable form of website hosting. Multiple users will share the resources of a secured server or group of secured servers in order to put their websites online for others to view. Bluehost offers several affordable shared hosting services so you can find the perfect shared hosting package for your website needs.
