Nowadays, Redis is an indispensable middleware in building the backend service of an app. As an ambitious team, we bought a Redis cluster under Amazon ElastiCache with the following features:

• Clustered with several shards, and each shard owns 3 nodes (each shard performs primary-replica)
• Encryption in transit enabled (or TLS) to assure no man-in-the-middle attack
• Redis AUTH enabled (of course we do not want a door without a key)

So far so good, it seems that we can concentrate on developing our product now. But wait, as the title says, the way is too long to get there!
