Eucalyptus is open source software for building Amazon Web Services-compatible private and hybrid clouds.
Requirements and Technical Notes
-
Eucalyptus is broken into five components: Cloud Controller, Walrus,
Cluster Controller, Storage Controller, Node Controller. There is also
an optional, proprietary VMware broker plugin, available from Eucalyptus
Systems. These components are software services and are arranged in
three layers: cloud, cluster, and nodes. You can install the components
on the same physical server or on separate physical servers as business,
security, and resource needs dictate.
-
The Node Controller requires libvirt and KVM.
-
The libraries that Eucalyptus depends on are described in detail in
the INSTALL file.
-
You will have to choose one of several network modes, which are
described in the installation guide. Your system's and network's
requirements will vary based on which mode you choose.
-
Generally, you will need two IP address ranges. The first range
is private, to be used only within the Eucalyptus system itself. The
second range is public, to be routable to and from end-users and VM
instances. Both sets must be unique to Eucalyptus, not in use by other
components or applications within your network. Static mode requires
only one available IP address range, and system mode does not require
an available IP address range.
