ABSTRACT
This chapter attempts to fill in the fundamentals for mission critical networked computing applications. It discusses the fundamentals of mission critical cloud applications and focuses on three objectives: maximal application survivability, unlimited application performance scalability, and zero data losses. These properties are desirable for all mission critical applications. The chapter describes the generic “DNA” sequence of the maximally survivable systems. It explores the historical background of the “DNA” sequence of maximally survivable systems, the necessary and sufficient conditions for the maximally survivable systems, and the introduction of Networked Computing Applications Architectures (NCA). The chapter defines the Unit of Transmission for four basic NCAs: messaging, storage, computing, and transaction processing. It also describes the steps required for embedding the maximally survivable sequence for a transaction processing system. The fundamentals on cloud application architecture, however, are surprisingly short. The basic NCA architectures include messaging, transaction, storage and computing.
