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

Why Auto Scale?

1. Reduce Wasted Capacity• Decrease costs• Increase utilization• “Do more with less”

2. Manage Unexpected Spikes • Avoid outages• Maintain SLAs

OverviewReactive 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 template2. Heat creates cloud application stack with scale group

and scale policy3. 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 alarm6. Monasca signals cloud application stack in heat7. 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)
