About Auto-Scaling?

What is Auto Scaling?
“Auto scaling is a cloud computing feature that allows
users to automatically scale cloud services, like virtual
machines (VM) and server capacities, up or down,
depending on defined situations”. - techopedia
3 Types of Auto Scaling
● Scheduled
● Reactive
● Predictive
“Horizontal Scaling” - Add/remove number of compute
resources
“Vertical Scaling”- Increase/decrease size of compute
resources
Up/Down
Performance
Rules
OrchestrationCompute
Load
Balancing

Why Auto Scale?
1. Reduce Wasted Capacity
• Decrease costs
• Increase utilization
• “Do more with less”
2. Manage Unexpected Spikes
• Avoid outages
• Maintain SLAs

Auto Scaling Cloud Applications

Overview
Reactive Horizontal Auto Scale
1. Monasca monitors VM scale group
memory and CPU
2. Combined CPU and Memory
utilization > X
3. Monasca alarm sends webhook
notification to Heat
4. Heat orchestrates nova and
neutron to create new VMs and
rebalance traffic
5. Monitoring continues...

1. Call Heat with a cloud application HOT template
2. Heat creates cloud application stack with scale group and
scale policy
3. Heat creates alarm definitions and scaling notifications in
Monasca
4. Monasca start to monitor the scale group elements
[[CLOUD APPLICATION AUTO-SCALING SETUP IS DONE]]
5. When Scale group reaches the alarm threshold
monasca detects and generates alarm
6. Monasca signals cloud application stack in heat
7. Heat either scale up or scale down based on the signal (here,
increment scale group elements by 1)
5-7 runs for ever ! (auto-scale)
