Cloud vs. Dedicated Server

Cloud Computing IaaS versus Dedicated Server Hosting

You have a number of infrastructure hosting options when it comes to the type of server, storage and network architecture you need for your applications, databases and websites. Some Cloud computing servers now perform and behave exactly like a dedicated server, providing greater reliability, flexibility, scalability, and incredible performance, while giving unprecendeted flexibility, and elastictiy while costing much less.  Below is a side-to-side comparison of the two most popular options to help you select the type that is best for your application needs.


Comparing Cloud Servers with Dedicated Servers


Cloud Servers

Dedicated Servers


Simply put, a true Cloud server or instance is hardware that operates via virtualization and the providers provisioning software, allowing you to modify key resources. Need more CPU power? Need more memory? Storage? All physical server resources can be adjusted on-demand without having to wait for a technician to power-down the server, open the server, install new RAM, and repower.

A dedicated server is a type of Internet hosting in which the client leases an entire server not shared with anyone else. This is more flexible than VPS hosting, as organizations have full control over the server(s), including choice of operating system, hardware, etc.

Operating System

Dedicated Operating System;
Support any x86 compatible operating system (Unix, Linux, MS Windows, and more)

Dedicated Operating System;
Most dedicated hosting services require you to select from a list of pre-approved OS and versions.

Software Applications

Customer can remotely install and manage any compatible software application

Customer can remotely install and manage any compatible software application

Administrative Access

Full Root access for Unix/Linux-based Servers. Full Administrative
access for Windows Servers

Root access for Unix Servers. Administrative access for Windows Servers

Remote OS Install/Reinstall



Remote Server Console Access



Remotely Reboot a “frozen” Server



Server Snapshots

Customer can take a server snapshot before making changes to it.
A simple mouse click will return server back to the original state if needed.

No snapshot feature.

Server Performance

Varies by cloud provider, some providers have very poor performance; other’s have performance that is the same or better than most dedicated servers.

Performs comparable to most cloud servers.

Data redundancy

Varies by provider. Some offer no redundancy some offer same data
center redundancy and others have multi-data center redundancy.

Lots of dedicated servers are on a single disk. Some dedicated servers are on a single parity disk (RAID 5) with no hot standby disk.

Power redundancy

Cloud servers run on a computing resource pool served by redundant
power PDUs, redundant power UPSs, redundant power generators, and redundant power grids (not all data centers were built
this way).

Many dedicated servers still sold today have a single power supply. Some dedicated servers have dual power supplies but they are often on a single power PDU.

Live hardware resource scaling

Most providers don’t offer on-demand vertical scaling with no-reboot. 
With some providers you can add CPU cores and RAM without rebooting
if the OS supports it.

Upgrading CPU, RAM, and/or disk space requires opening a support ticket shutting down the server, and waiting for the technician to update the hardware configuration resulting in downtime.

Hardware upgrade

Some Cloud Computing providers were deisnged in a way that customers
are informed that they must move their server and data.  Other cloud providers will automatically migrate customers to another server without
any downtime.

Dedicated server hosting companies will often allow customers to run on old, out-dated hardware for a long time, when the servers do get replaced the customer is often forced to renew their agreement and select a new server, price and reinstall & re-configure everything.
