Cloud Computing

Cloud computing is a computing model, where resources such as computing power, storage, network and software are abstracted and provided as services on the Internet in a remotely accessible fashion. Billing models for these services are generally similar to the ones adopted for public utilities. On-demand availability, ease of provisioning, dynamic and virtually infinite scalability are some of the key attributes of cloud computing.

An infrastructure setup using the cloud computing model is generally referred to as the “cloud”. The following are the broad categories of services available on the cloud:

  • Infrastructure As A Service (IAAS)
  • Platform As A Service (PAAS)
  • Software As A Service (SAAS)

Amazon Web Services (AWS) is one of the major players providing IAAS. They have two popular services – Elastic Compute Cloud (EC2) and Simple Storage Service (S3). These services are available through web services.

Eucalyptus Networking


In System mode, CC generates and assigns a random MAC address to the VM instance while requesting NC to bring up the instance. NC attaches the VM instance’s virtual NIC to the physical NIC on the node through a bridge. This mode requires that the Nodes are connected to the enterprise network directly. Instances obtain an IP address using DHCP, just as physical machines on the network do.

This mode is very easy to setup as it does not have any additional prerequisites in terms of networking, except for a running DHCP server on enterprise network, and is a good way to get started with Eucalyptus, particularly if you want to set it up on your laptop/desktop to get a basic understanding.

This mode of networking is similar to “Bridged Networking” that hypervisors like VMware, VirtualBox etc. offer or like “tap” networking offered by KVM/Qemu.

[Eucalyptus Beginner’s Guide – UEC edition] Chapter 2 – Installation & Configuration

with 42 comments

Chapter 1
Introduction to UEC and its components
Chapter 3
Web Interface

The following sections describe how to install and configure a basic UEC setup spanning 3 servers. 2 Servers(Server1 and Server2) will run Lucid 64-bit server version and the third server will run Lucid Desktop 64-bit version(Client1). We have decided on installing the Desktop version on Client1 so that we can use Firefox or other browsers to access the web interface of UEC and also to use RDP/VNC clients during the image creation process.


What we have used as a sample setup is a typical minimal Eucalyptus setup. Client1 above need not be a dedicated machine. If you need to setup Eucalyptus on a single server, you can refer to UEC: CC and NC on a single machine . However, such a setup will not support Managed and Managed-NOVLAN modes of networking.
