Auto Scaling allows your application to always have the compute capacity needed and reduces the need to manually monitor server capacity. You can autoscale based on incoming requests (front-end) or number of jobs in the queue and how long jobs have been in the queue (back-end).
The benefits of Auto Scaling:
-
- Responsive server usage based on traffic load
- Handle unexpected traffic spikes and avoid downtime
- Plan scaling activities if you have predictable load changes
- Uncover and replace faulty instances and unhealthy applications automatically
