Question
I'm able to connect to an ElastiCache Redis instance in a VPC from EC2 instances. But I would like to know if there is a way to connect to an ElastiCache Redis node outside of Amazon EC2 instances, such as from my local dev setup or VPS instances provided by other vendors.
Currently when trying from my local set up:
redis-cli -h my-node-endpoint -p 6379
I only get a timeout after some time.

Update 2018
The previous answer was accurate when written, however it is now possible with some configuration to access redis cache from outside using the directions according to [Accessing ElastiCache Resources from Outside AWS](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/accessing- elasticache.html#access-from-outside-aws)
Old Answer
No, you can't without resorting to 'tricks' such as a tunnel, which maybe OK for testing but will kill any real benefit of using a super-fast cache with the added latency/overhead.
The Old FAQ under How is using Amazon ElastiCache inside a VPC different from using it outside? :
An Amazon ElastiCache Cluster, inside or outside a VPC, is never allowed to be accessed from the Internet
However, this language has been removed in the current faq
