BETA release for WASABi (Windows Azure Autoscaling Application Block) is ready for download from NuGet Here:

 A list of October Release and latest changes are available at:

 

New Features:

  • The Stabilizer increases hysteresis in the block's scaling operations by preventing reactive rules from performing repeated and erratic scaling actions.
  • Application throttling provides a new reactive rule action for changing a Windows Azure configuration setting for a specific role when a rule condition is satisfied. Through this, you can limit or disable certain relatively expensive operations in your application when the load is above certain thresholds.
  • E-mail notifications allow for hypothetical scaling. The block still evaluates the rules and makes a decision (recommendation) on what should be scaled and how, but instead of performing the change it sends a notification to configured recipients (human operators) to scale manually or to perform some other action.
  • Collection of role instance count values for every role defined in the service information store (this is mainly used by the stabilizer feature, but users could also use it in operands for rule conditions).
  • Ability to define custom actions for reactive rules.
  • Ability to specify custom operands for use in reactive rule conditions.
  • New "Max" and "Growth" aggregate functions in operand definition.
  •  Enhanced log messages for rules evaluation and scaling to better determine what is happening in the system.
    • Added an Evaluation ID to correlate all log messages for a specific evaluation pass.
    • Added JSON payloads to log messages to assist tools that monitor and interpret the messages.
    • Provided utility classes and constant definitions to read and parse the log messages.
  • Configuration tool enhancements, including better names and descriptions for configuration objects, validation, and a Windows Azure connection string editor.
