Subject Apache CloudStack 4.1.0 Released
Date Wed, 05 Jun 2013 02:17:41 GMT
The Apache CloudStack project is pleased to announce the 4.1.0 release
of the CloudStack Infrastructure-as-a-Service (IaaS) cloud orchestration
platform. This is the first major release from Apache CloudStack since
its graduation from the Apache Incubator on March 20th. 

Apache CloudStack is an integrated software platform that allows users
to build a feature-rich IaaS. CloudStack includes an intuitive user
interface and rich API for managing the compute, networking, accounting,
and storage resources for private, hybrid, or public clouds. 

The 4.1.0 release represents more than five months of development effort
by the Apache CloudStack community. The release includes many new
features and bugfixes from the 4.0.x cycle. The 4.1.0 release also marks
major changes in the codebase to make CloudStack easier for developers,
a new structure for creating RPM/Debian packages, and completes the
changeover to using Maven as a build tool.

## New Features

Some of the notable new features in Apache CloudStack 4.1.0 include:

* An API discovery service that allows an end point to list its
supported APIs and their details.
* Added an Events Framework to CloudStack to provide an "event bus" with
publish, subscribe, and unsubscribe semantics. Includes a RabbitMQ
plugin that can interact with AMQP servers. Introduces the notion of a
state change event. 
* Implement L3 router functionality in the Nicira NVP plugin, and
including support for KVM (previously Xen-only). 
* API request throttling to prevent attacks via frequent API requests. 
* AWS-style regions. 
* Egress firewall rules for guest networks. 
* Resizing root and data volumes. 
* Reset SSH key to access VMs. 
* Support for EC2 Query API. 
* Autoscaling support in conjunction with load balancing devices such as

In addition to the official source code release, individual contributors
also make convenience binaries available. 4.1.0 convenience binaries
should be available within a day or so of the release announcement.

Note that there is a known issue with 4.1.0 and a recent Tomcat release.
This has been addressed in the convenience binaries, but is still
present in 4.1.0 source release. We will be working on a 4.1.1 release
that will contain that fix shortly.

## CloudStack Collaboration Conference

The CloudStack community will be gathering for its second conference
