Amazon AWS EC2 storage types
You can connect different storage types to Amazon EC2 instances , two of them provided naively by Amazon platform and the rest are either provided by external sources or tweaks. In any EC2 instance (except micro) you have instance storage included in a package. You can also use elastic block storage (EBS) and have an option connecting different 3rd party storage over the network. Instance storage is a fast non-persistent storage provided by Amazon. It means it will revert to it`s original state after any system shutdown, erasing any changes you have applied to the file-system. It is very useful for running “dumb” servers that do not store data locally or as an additional storage for temporary files. Elastic block storage (EBS) is a persistent storage provided by Amazon. All and any data stored on it is available after instance shutdown and can be manipulated with on device level. For example you can detach an EBS volume from one instance and attach it to another
