New Features

Eucalyptus 4.0.0 introduces the following new features.

Feature Description
New architecture We made changes to the way the Eucalyptus components are installed and registered. We separated the user-facing services from the database host (the CLC). This makes for better security and for better availability of the user-facing services. For more information, see Plan Your Installation.
New storage architecture We added an object storage system that provides a S3 API interface. This interface is designed to scale out horizontally. For more information, see Object Storage.
New networking mode We added support for the new Edge networking mode. For more information, see the Installation Guide..
New default administrator roles We added support for three default admininstrator roles. For more information, see Administration Roles.
New ELB features We added support in elastic load balancing (ELB) to support session stickiness and SSL certificates. For more information about sticky sessions, see Creating Elastic Load Balancing Sticky Sessions. For more information about SSL certificates, see Uploading SSL Certificates for Elastic Load Balancing.
Deprecated console We deprecated the Administration Console. The IAM functionality was moved to the User Console. The following tasks must now be done using the CLI: change VM types, create accounts, delete accounts, download certificates, and generate reports.
Stock DHCP server package Previous versions of Eucalyptus applied a private DHCP entry to VNET_DHCPDAEMON for the Cluster Controller (CC) and the Node Controller (NC). In 4.0.0, we recommend that the VNET_DHCPDAEMON file be edited to use the dhcpinstead of the dhcp41 file. For more information, see "Switch to the Stock DHCP Package" in the 4.0.0 Eucalyptus Installation Guide.
New schemas We created new schemas for the backend services that correspond to the user-facing services. For more information, see the Internal APIs section in Schema Documentation.
New technical preview feature We are offering CloudFormation templates in technical preview. For more information about this feature, go to the draft specification. For more information about AWS CloudFormation go to Working with AWS CloudFormation Templates.
