·         Ubuntu Enterprise Cloud and  Eucalyptus

Ubuntu Enterprise Cloud, UEC, is a stack of applications from Canonical included with Ubuntu Server Edition. UEC includes Eucalyptus along with a number of other open source software. UEC makes it very easy to install and configure the cloud.

There are a few differences between the Ubuntu Server Edition and the Ubuntu Desktop Edition. It should be noted that both editions use the same apt repositories. Kernel differences can be identified mainly between the two editions.  The Server Edition uses the Deadline I/O scheduler whereas the Desktop edition uses CFQ scheduler. Preemption is switched off in the Server Edition. The timer interrupt is 100 Hz in the Server Edition and 250 Hz in the Desktop Edition.

Well, making it simple, UEC is a cloud computing technology allows you to build a private cloud deployment model in your own environment. You can pool your servers into a centrally managed resource pool behind your firewall on your own network. In UEC, you can manage all your resources yourself using the UEC management tool Landscape. Also UEC allows you to burst into public cloud platforms such as EC2 giving you an added level of flexibility. Figure 7, a screenshot representing Landscape tool after a private cloud has created.  There are other management tools such as Rightscale, CohesiveFX, ElasticFox and etc.

But why UEC comes with EC2 architecture and APIs??

Amazon and EC2 is the momentum leader in the cloud business. So tying up with the leader will create a competitive advantage over other cloud providers. Best captures shift from product to service economy. Designing for EC2 guarantees on-demand deployment and scalability, two key benefits of cloud computing, that’s obviously cool. The Coolest feature I suppose is EC2 has already has many implementations such as Eucalyptus, Globus Nimbus, Open Nebula and etc. Also Top 2 listed most popular AMIs (Amazon Machine Images) is Ubuntu.

          Eucalyptus is a cloud based software available under GPL (General Public License) that helps in creating and managing a private or even a publicly accessible cloud. It provides an EC2-compatible cloud computing platform and S3-compatible cloud storage platform. Eucalyptus has become very popular and is seen as one of the key open source cloud platforms. Since Eucalyptus makes its services available through EC2/S3 compatible APIs, the client tools written for AWS can be used with Eucalyptus as well.
