|Release Notes / 4.4.0|
This topic lists new features in Eucalyptus 4.4.0.
Eucalyptus 4.4.0 introduces the following new features.
|EBS snapshot delta support.||Eucalyptus snapshots now can be stored as a
delta to a previous checkpoint (delta or a full snapshot). Volume
restore occurs from the first snapshot, plus the deltas. This
feature is supported only when Ceph-RBD is used as the block storage backend provider
for the Storage Controller (SC). The cloud administrator can set the
maximum number of snapshot deltas between full volume checkpoints.
EBS snapshot delta support is a Technical Preview feature. For information about Technical Preview features in Eucalyptus, see Special Status Release Features.
|Cross-origin resource sharing (CORS) configuration for S3 buckets support.||CORS defines a way for client web applications that are loaded in one domain to interact with resources in a different domain. With CORS support in Eucalyptus S3, you can build rich client-side web applications with S3 and selectively allow cross-origin access to your Eucalyptus S3 resources.|
|Mido 5.2 support.||In Eucalyptus 4.4.0, VPCMIDO mode relies on MEM version 5.2.x.|
|OpenID Connect (OIDC) support||You can now log into the Eucalyptus
Management Console using InCommon identities, via Globus OAuth 2.0
OpenID Connect (OIDC) is a Controlled Availability feature. For information about Controlled Availability features in Eucalyptus, see Special Status Release Features.
|Signature Version 4 (SigV4) for S3 support.||Eucalyptus S3 now supports the SigV4 signing process for all previously supported operations.|
|ELB using SWF support.||The ELB service now uses the Eucalyptus Simple Workflow service (SWF) to coordinate distributed tasks. This enhancement improves scalability and troubleshooting for the ELB service.|
