The document discusses three AIOps technologies: Lambda, Kappa, and Zeta. It describes Lambda architecture, which processes data through parallel batch and real-time streams to provide consistent views with low latency. The architecture achieves scalability and performance through immutable data storage, denormalized data structures, and precomputed views. It also lists the basic tenets that enable Lambda's scalability, such as immutable data, data denormalization, and precomputed views.
