Mission critical computing requires three pillars: Reliability, Availability, and Scalability – “RAS” for short. Availability and Scalability are well-known and served by Active/Active data replication architectures. Reliability and data integrity are now at the forefront of business concerns, and a primary challenge for businesses to solve. They remain a critical customer and regulatory concern which are adversely affected by software bugs, hardware errors, malware, hacking, and many other common problems.
This new solution centers on Validation Architectures to address reliability and data integrity. In this talk, we review three Levels of Active/Active and Validation Architectures and an advanced best-of-both-worlds architecture to maximize all three pillars of RAS. We outline several use cases of these architectures using HPE NonStop and ProLiant Servers based on preventing election fraud, system upgrade proofs, and gambling.
