Minimal effort image storage, transformation and delivery.

IaaS

AWS: Serverless Image Handler

• Storage: You upload to S3
• Delivery + Transformation: CloudFront -> API Gateway -> Lambda (Node, Sharp/Thumbor) -> S3
• CloudFormation: 1 click and fill up some fields.
• Only predefined S3 Bucket, no dynamic bucket routing.
• Transformation is encoded into Base64 that can be generated by anyone. You can add Signed URL but it's quite troublesome.

History

Basically the game No Man's Sky UPS was a world with infinite possibility. I was very excited about the release of such a game because it created new possibility in games and might even inspire some one to do it better. The game flopped on release but the concept was unique, I was excited of what's to come. Fast forward 3 years later, still very little innovation in such genre.

Two incident caught my attention recently, Minecraft 2b2t and Sky Citizen.

Minecraft 2b2t server is a good example of maintaining a world with infinite possibility. 4000 GB of data, and <100 players can be on it at a time.
