Types of Instances and the major differences between the instances

Instance Types
There are very large number of instances availaible from the AWS and depending on your compute requirement you want to use the same. But here is general categorization of the instances.

Micro
Small
Medium 
Large

We could use very large instance types which can cost very high but when you are running them on hourly charge you are actually paying less. For e.g. If you spin up quadraple extra large instance for an hour and spend like $2. Rather than purchasing whole bunch of harware and running in your datacenter.





Differences in instances

1. Memory
2. Compute Power
3. Block Storage
4. Network Performance
5. EBS optimization

These are key differences in instances and based on the your requirements you can find the optmized combination which suits your requirement.
