Hydra (stylized as HYDRA) is an early, discontinued, capability-based, object-oriented microkernel designed to support a wide range of possible operating systems to run on it.[1] Hydra was created as part of the C.mmp project at Carnegie Mellon University in 1971.[2]
The name is based on the ancient Greek mythological creature the hydra.
Hydra was designed to be modular and secure, and intended to be flexible enough for easy experimentation.[3] The system was implemented in the programming language BLISS.[4]
