Dell's PowerEdge C2100

Dell has outfitted its PowerEdge C2100 and C6100 servers with Canonical’s Ubuntu Enterprise Cloud (UEC) in order to serve Ubuntu-based cloud services.

These Ubuntu cloud servers are very useful for companies developing applications to run on Amazon Web Services (AWS). These companies can take advantage of the PowerEdge C2100 and C6100 servers to test applications locally before uploading them to the paid AWS platform.

The servers have a preconfigured testing and development environment, Eucalyptus, which duplicates the AWS APIs. Eucalyptus is a private cloud software that runs on the Ubuntu Server Edition operating system.

The C2100 server is suggested to act as a cloud compute node, while the C6100 one can act either as a cloud compute server or as both a server and a node.

This is the first time that Dell sales Linux-based Ubuntu OS on their servers, although it has used Ubuntu Desktop Edition for some of their netbooks, laptops and PCs.

Dell is making a good approach for companies that want to improve their applications and to save money on the same time.

The OSI Reference Model consists of 7 layers. When OSI was in active development, new protocols and specifications to implement the functions specified by each layer were made. Today, the OSI model can be used as a standard of comparison to other networking models (to TCP/IP, for example).

Let’s take a look in the OSI Reference Model layers:

7) Application.

It provides an interface between the communications software and any applications that need to communicate outside the computer on which the application resides. It also defines the authentication process.
