The How
How we approached this initiative and what we have learned along the way

6.
Supervised Learning
• When input and output, both labels are known
• model learns from data to predict output for similar input data
Unsupervised Learning
• When output data is unknown
• it is needed to find patterns in data given
Reinforcement Learning
• Algorithms learn to perform an action from experience.
• Here algorithms learn through trial and error, which action yields the greatest rewards.
• The objective is to choose actions that maximize the expected reward over a given amount of time.
Which AI?

7.
Simulation
Elements
• Simulation of hosts, VMs, Service Offerings
Functionalities
• Only required functionality for VM placement
Evaluation
• Way of comparing the state of the system
Fuzzy
• Fuzzy functions to describe the Cloudstack Status
