CPNext

CPNext is a new technology currently being experimented on by the Club Penguin Team. It is currently only being used on the My Penguin mobile application, but soon, it will be expanded to everywhere on Club Penguin. Many people do not like this new idea, especially people in a small community called Club Penguin Armies.

Rooms
CPNext works completely differently then the current server system. Currently, each server is one "shard" of Club Penguin, meaning one reflection of the island which a certain amount of users can play. In CPNext, every room is in effect a shard. As more users join a certain room, more reflections of the room are created, allowing lag free play and busy rooms. In this system, many versions of a popular room could coexist with only one version of a less popular room, making it easier to hang out with more penguins. This allows all rooms to have the same amount of penguins so long as there is demand for the room. The team also will have the ability to control the amount of penguins in a given room before another version is created.

Future Concepts
Spike Hike has stated that Club Penguin could conceptually have an unlimited number of rooms for penguins to explore, with rooms being revealed over time as penguins discover them. Missions like Operation: Hot Sauce that happen in world only could exist permanently, with the engine of the game grouping EPF agents who wish to play them in mirror versions of real rooms. You meet friends by jumping to friend, a new version of Server Jumping. Mascots would be met by teleporting to them from friends lists, ruining the point of mascot tracking.

Benefits
On November 16, 2013, Spike commented on the fan blog Club Penguin Memories about the benefits of the new technology.

Implementation in My Penguin
Currently, CPNext is used in My Penguin to create multiple reflections of players' igloos for their buddies to visit. It also renders the 3D Penguins for the game, replacing almost the entire current main engine of the game.

The new tech will most likely be used in the next year.
