Auto Scaling in the Amazon Cloud: Netflix's Approach and Lessons Learned
Another great post for today from the engineering team at Netflix:
Auto scaling is a very powerful tool, but it can also be a double-edged sword. Without the proper configuration and testing it can do more harm than good. A number of edge cases may occur when attempting to optimize or make the configuration more complex. As seen above, when configured carefully and correctly, auto scaling can increase availability while simultaneously decreasing overall costs.
