[Announce] Apache Stratos (incubating) 4.0.0-M5 is READY

[Imesh Gunaratne <im...@apache.org>]

Hi All,

Apache Stratos (incubating) 4.0.0-M5 milestone is now ready. This is a
developer preview/snapshot of the current development track and it could be
used as a baseline for contributing to the product stack.

Please find the binary packages of this milestones at:
https://dist.apache.org/repos/dist/dev/incubator/stratos/milestones/4.0.0-incubating-m5/

Source code could be fetched using git tag 4.0.0-incubating-m5:
>git clone https://git-wip-us.apache.org/repos/asf/incubator-stratos.git
>cd incubator-stratos
>git checkout tags/4.0.0-incubating-m5

Please find the Installation Guide, Puppet Guide and REST API Guide
attached with this mail.


*Major Functional Changes Introduced*

1. New Artifact Deployment Process:

In this milestone a major change has been done in the artifact deployment
process (artifacts: partitions, deployment policies, autoscaling policies
and cartridges).
In previous milestones all artifacts were deployed using file based
deployers in cloud controller and autoscaler. Now file deployers have been
removed and a new set of service methods have been introduced in REST API
for deploying artifacts. Please refer the attached REST API guide for more
information.

2. Load Balancers as a Service:

Another major change was done in this milestone on how load balancers are
defined. From this milestone on-wards load balancers are defined as service
cartridges and will be spawned for each network partition on demand. Each
network partition would have a default load balancer instance.

3. Puppet Cartridge Images:

In this milestone puppet based cartridge images were introduced. A sample
PHP cartridge image was created using Puppet scripts. These sample puppet
scripts could be found in the git repository.
