Video Summary

There are 7 types of instance on AWS: - R: for RAM-intensive applications - C: for CPU-intensive applications - M: for general-purpose applications - I: for I/O-intensive applications - G: for applications that require a GPU - T2/T3: burstable instances that are good for short-term spikes in load - T2/T3 unlimited: instances with unlimited burst capacity To choose the right instance type, you can use the EC2 Instances Comparison page. T2/T3 instances are good for applications that have occasional spikes in load, but you should be careful not to overuse them, as they can become very slow if you run out of credits. T2/T3 unlimited instances are good for applications that have sustained periods of high load, but you should be aware that you will pay more for them.
