Functionality
The Eucalyptus User Console provides an interface for users to self-service provision and configure compute, network, and storage resources. Development and test teams can manage virtual instances using built-in key management and encryption capabilities. Access to virtual instances is available using familiar SSH and RDP mechanisms. Virtual instances with application configuration can be stopped and restarted using encrypted boot from EBS capability.
IaaS service components Cloud Controller, Cluster Controller, Walrus, Storage Controller, and VMware Broker are configurable as redundant systems that are resilient to multiple types of failures. Management state of the cloud machine is preserved and reverted to normal operating conditions in the event of a hardware or software failure.
Eucalyptus can run multiple versions of Windows and Linux virtual machine images. Users can build a library of Eucalyptus Machine Images (EMIs) with application metadata that are decoupled from infrastructure details to allow them to run on Eucalyptus clouds. Amazon Machine Images are also compatible with Eucalyptus clouds. VMware Images and vApps can be converted to run on Eucalyptus clouds and AWS public clouds.
Eucalyptus user identity management can be integrated with existing Microsoft Active Directory or LDAP systems to have fine-grained role based access control over cloud resources.
Eucalyptus supports storage area network devices to take advantage of storage arrays to improve performance and reliability. Eucalyptus Machine Images can be backed by EBS-like persistent storage volumes, improving the performance of image launch time and enabling fully persistent virtual machine instances. Eucalyptus also supports direct-attached storage.
Eucalyptus 3.3 offers new features for AWS compatibility. These include resource tagging, which allows application developers and cloud administrators to assign customizable metadata tags to resources such as firewalls, load balancers, Web servers, and individual workloads to better identify them. Eucalyptus 3.3 also supports an expanded set of instance types to more closely align to instance types in Amazon EC2.
Eucalyptus 3.3 also includes a new Maintenance Mode that allows cloud administrators to perform maintenance on Eucalyptus clouds with zero downtime to instances or cloud applications. It also includes new user console features such as a Magic Search Bar, and an easy option to allow users to change their password.
