Hi,

I am currently working on an OpenStack Cloud network known as NeCTAR and am trying to understand the basic principles involved in the implementation of the environment. I believe that OpenStack networks these days are more or less modeled on the concepts integrated by AWS in their services, provided to the end user but does OpenStack in general have any specific functionalities or advantages on its own that makes it the standard choice by many vendors ? Also, does OpenStack have any significant advantages for specific types of software applications in general or is it a highly generic model providing a range of functionalities to end users to deploy their applications onto and run ?

Well, OpenStack is:

1. Fairly mature. Meaning that it's got a reasonably complete set of the features needed by most to run a Cloud
2. Well-tested
3. Supported by major vendors
4. Non-proprietary
5. Free

AWS is popular, but Amazon owns it and they're not sharing it. If you want something you can run on your own premises using your own equipment, you need something like OpenStack.

I certainly agree with Tim's points.

I don't know what Amazon has going on "under the hood" and can only speculate. In terms of OpenStack there is no one type of networking [1]. The majority of people (based on survey) use Neutron and OVS, but there are others that use the Nova plugin directly. Within Neutron alone there are dozens of drivers ranging from generic SDN control to vendor-specific integrations. There are even network interface vendors [2] with hardware specifically for OVS/OpenStack.

You have a great deal of flexibility when it comes to OpenStack and networking. For instance, I know of a major cloud provider that has a custom network management solution that conforms to the Neutron API, so as far as OpenStack components are concerned they are working directly with Neutron.
