The Problem

Cloud networking bases on tech and protocols that were not initially designed for it. This has lead to unnecessary overhead and complexity in all phases of a cloud service. Tunneling protocols generate inherent cascading and encapsulation especially in multi tenant systems. The problem increases by vendor specific configuration requirements and heterogenous architectures. This complexity leads to systems which are hard to reason about, prone to errors, energy inefficient and increases the difficulty of configuration and maintenance. Continue reading
