EC2 snitches should be used only if you're 100% sure that you never will add another DC outside of AWS (but can you be sure in that?). These snitches just slightly simplify your life by inferring the DC & rack information, instead of specifying it manually as in case of GossingPropertyFileSnitch (GPFS).

Pros of using GPFS:

  • You can add data centers outside of AWS. For example, to implement hybrid cloud deployments (AWS/other cloud, or AWS/on-premise), or to migrate data out of AWS, ...

Cons of using GPFS:

  • You need to specify DC & rack information manually (but I don't believe that it will make a lot of problems - and I think that you can even automate it by asking for meta-information of node when it's provisioned).
