A cloud server is primarily an Infrastructure as a Service (IaaS) based cloud service model. There are two types of cloud server: logical and physical. A cloud server is considered to be logical when it is delivered through server virtualization. In this delivery model, the physical server is logically distributed into two or more logical servers, each of which has a separate OS, user interface and apps, although they share physical components from the underlying physical server.
A VPS can be rebooted without affecting the other VPSes on that machine. You have a server operating system (OS) with root access, and you can install software as you would if you had a dedicated hosting plan with your own server. A portion of the physical host’s CPU and memory are dedicated to your VPS, but you also share additional resources with the other virtual servers.
With shared hosting, which is more common among small and medium sized businesses, the client pays for a set amount of space (storage) on a single server, and that server’s resources are shared by a number of other websites. It’s a cost-efficient, low-maintenance way to host a website or application, and the hosting company is responsible for managing, maintaining, and updating the units.

When a website is hosted on shared hosting, the website is placed on the same server as many other sites, ranging from a few to hundreds. Typically in this setup, all domains share resources, such as RAM and CPU from the same server. Cloud hosting, on the other hand, offers nearly unlimited ability to handle high traffic spikes. On Cloud, your website is hosted not only on one but on several servers connected to work as one. Your websites don’t depend on only one Server– even if one server is inaccessible, the Data is retrieved and processed by the other available servers with no downtime.
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.
I've observed or been a part of buying decisions for a few thousand server customers, from small-business owners getting a website online for the first time to established platforms with tens of millions of visits every day. While each of those purchasers had different requirements and priorities for a cloud server, a few key deciding factors were consistent across those decisions:
One of the most popular hybrid cloud configurations is to use dedicated servers for back-end applications. The power of these servers creates the most robust environment for data storage and movement. The front-end is hosted on cloud servers. This configuration works well for Software as a Service (SaaS) applications, which require flexibility and scalability depending on customer-facing metrics.

As you can see, there are many pros and cons of each setup. For this reason, SysGen often recommends a hybrid model to clients – meaning a combination of both in-house and cloud-based solutions. Going hybrid gives clients the best of both worlds. Having some in-house server hardware can be suitable for companies that do not want to rely on the Internet. And at the same time, businesses can reap the benefits of a cloud solution, such as Microsoft Exchange email, to allow users to connect from anywhere with a high degree of uptime. SysGen actually guarantees 99.99% uptime to its clients with cloud-based email.


Cloud server hosting is when hosting services are made available to customers on demand via the Internet. Rather than being provided by a single server or virtual server, cloud server hosting services are provided by multiple connected servers that comprise a cloud. Cloud server hosting is also sometimes referred to as cluster server hosting or server on-demand hosting.
VPS and cloud computing are not mutually exclusive options. You can host your VPS in a virtualized environment. This allows you to convert one physical server into multiple virtual machines, each of which acts like a unique physical device for running both IT resources and web applications in a flexible, instantly scalable and cost-efficient manner.

Many cloud web hosts offer unlimited monthly data transfers, so other factors may help you decide which service is best for your business. That said, if you're interested in "unlimited" anything, no matter if it's data or storage, be sure to read the tiny print to make sure that there aren't any surprises. In other words, make sure your definition of unlimited matches the hosting service's definition. They can be two very different things.

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.
