FR12 introduce basic support for comma-separated list of management servers for agents, while makes an explicit LB unnecessary. On the agent side, the 'host' is saved as: <comma separated addresses>@<algorithm name>. Where the algorithm name is the name of the lb algorithm. The This FR introduces two new global settings: - indirect.agent.lb.algorithm: The algorithm for the indirect agent LB. - indirect.agent.lb.check.interval: The preferred host check interval for the agent's background task that checks and switches to agent's preferred host. Any changes to the above two global settings and the 'host' setting does not require restarting of the management server(s). The indirect.agent.lb.algorithm supports following algorithm options: - static: use the list as provided. - roundrobin: evenly spreads hosts across management servers. - shuffle: (pseudo) randomly sorts the list (not recommended for production). From the agent's perspective, the first address in the propagated list will be considered the preferred host. A new background task can be activated by configuring the indirect.agent.lb.check.interval which is a cluster level global setting from CloudStack or admins can override this by configuring the 'host.lb.check.interval' in the host's agent.properties file. Comma-separated management server list is propagated to agents on following cases: - Addition of a host (including ssvm, cpvm systevms). - Connection or reconnection by the agents to a management server. - After admin changes the 'host' and/or the 'indirect.agent.lb.algorithm' global settings. First the agent connects to the management server and sends its current management server list, which is compared by the management server and in case of failure a new/update list is sent for the agent to persist. Every time agent gets a ms-host list and the algorithm, the host specific background check interval is also sent and it dynamically reconfigures the background task without need to restart agents. The 'static' and 'roundrobin' algorithms, strictly checks for the order as expected by them, however, the 'shuffle' algorithm just checks for content and not the order of the comma separate ms host addresses.

Apache CloudStack 
Apache CloudStack is open source software designed to deploy and manage large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform. CloudStack is used by a number of service providers to offer public cloud services, and by many companies to provide an on-premises (private) cloud offering, or as part of a hybrid cloud solution.
CloudStack is a turnkey solution that includes the entire "stack" of features most organizations want with an IaaS cloud: compute orchestration, Network-as-a-Service, user and account management, a full and open native API, resource accounting, and a first-class User Interface (UI).
CloudStack currently supports the most popular hypervisors: VMware vSphere, KVM, XenServer, XenProject and Hyper-V as well as LXC containers.
Users can manage their cloud with an easy to use Web interface, command line tools, and/or a full-featured query based API.

Who Uses CloudStack?
-
There are more than 150 known organizations using Apache CloudStack (or a commercial distribution of CloudStack). Our users include many major service providers running CloudStack to offer public cloud services, product vendors who incorporate or integrate with CloudStack in their own products, organizations who have used CloudStack to build their own private clouds, and systems integrators that offer CloudStack related services.

BEFORE using any encryption software, please check your country's laws, regulations and policies concerning the import, possession, or use, and re-export of encryption software, to see if this is permitted. See http://www.wassenaar.org/ for more information.
The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has classified this software as Export Commodity Control Number (ECCN) 5D002.C.1, which includes information security software using or performing cryptographic functions with asymmetric algorithms. The form and manner of this Apache Software Foundation distribution makes it eligible for export under the License Exception ENC Technology Software Unrestricted (TSU) exception (see the BIS Export Administration Regulations, Section 740.13) for both object code and source code.
The following provides more details on the included cryptographic software:
- CloudStack makes use of JaSypt cryptographic libraries
- CloudStack has a system requirement of MySQL, and uses native database encryption functionality.
- CloudStack makes use of the Bouncy Castle general-purpose encryption library.
- CloudStack can optionally interacts with and controls OpenSwan-based VPNs.
- CloudStack has a dependency on Apache WSS4J as part of the AWSAPI implementation.
