Building a Vmware Powered Hybrid Cloud using Ecalyptus

The Cloud means many things to many different persons,but personally I view a Cloud as a distinct pool of  computing resources that can be manage centrally, provides the ability to scale resources via pre configured policies and lastly provides the ability to automate manual requests such as Virtual Machine creation and deployment.

Though not recommended by many IT professionals, I am planning on making our IT department an internal service provider. In this vain it is my vision to build out a Private Cloud that can provide self service to authorized internal clients such as our developers and application administrators.Currently we utilize a Vmware Vsphere platform, but in another few months this platform will possess all the attributes of a true cloud.To provide the functions necessary I have decided that we will look at the Open Source Eucalyptus platform.

Eucalyptus is Open Source so it reduces our initial capital expenditure ,it is compatible with Vmware and it has the ability to support Amazon based workloads thus providing a Hybrid platform mangement tool.

At Stage one, we will roll out a Private Cloud  that will allow authorized internal clients to perform various tasks related to a an assigned blocked of computing resources.

At Stage two we will seek to allow the migration of workloads between Amazon and our Vmware based private cloud,this should provide Disaster recovery and scalability benefits to our group.

DATA CENTER + SDN EQUALS TRUE VIRTUAL NETWORKS

Multi Tenant data centers being used to provide cloud services has led to a number of network requirements that are difficult to meet using VRF, Q-In-Q or other tunneling techniques.A Cloud data center customer needs to be able to provision network resources such as virtual switches and RFC 1918 IP addresses  without needing to consider similar resources being used by other tenants. Software Defined networking seeks to provide an END-to-END virtual network that consists of virtual forwarding tables ,virtual routers,virtual switches and controllers.  Software Defined Networking can be used to create logical networks that consist of virtual network gear. SDN tracks the state of the underlying physical data center network along with the overlaying virtual networks.

State changes are recorded and the Physical or Logical components affected by these said state changes are configured to have their settings and operations updated to support the changes made by the data center’s customer. Software defined networking’s ability to provide distributed,rule driven control of large physical network elements presents a new way of virtualizing network resources.
