Feature Overview

As a  customer i am  interested in combining Watcher strategies. for example:

• Combining Zone migration / evac for day 2 maintenance with workload balancing so i'll have the optimal spread across my functioning nodes 
• Combining Node consolidation with workload balancing so i’ll be able to shutdown underutilized nodes and have the workload being spread optimally on my other nodes 

Goals 

• Combination of various strategies will enable to execute complex resource balancing in single plan
• Currently one strategy execution needs to end first before another can start which sometimes might end with instances moving multiple times within the cloud. 

Requirements

Done 
Using Watcher interface it is possible to combine and execute multiple strategies together to lower total number of actions required for having the cloud in a requested state.

Documentation of how to layer said strategies to be used in tandem

Use Cases 

• Workload consolidation and workload balancing strategies
• Zone migration and workload balancing strategies
• Multiple balancing strategies based on variety of metrics
  • Network latency would be most used metric to balance from with additional metrics

Out of Scope...

Documentation Considerations ...

Questions to Answer 

• Should multiples strategies be executed sequentially or in a composition of multiple algorithms?
•  Are multiple workload balancing strategies with different metrics under different weights the core mechanism to support tiering ?
