Metaspex automates the engineering of high quality Cloud and Microservices-based back-end transactional applications (so-called "Software as a Service" and "Multitenant"). Until now, these solutions were produced at a very high cost, using a "human wave" approach inherited from the 70s, and reserved to a few companies with very deep pockets. Metaspex's original patent-pending technology cuts down these costs, by taking rule-based business-analysis level input ("Ontological"), letting the computer perform the programming tasks, without the usual human intervention, and the defects associated. The code, automatically produced, defeats the usual "abstraction penalty" rule, as it is of a higher quality than typical programmer code, and requires often a fraction of the data center resources equivalent man-programmed systems need. It can sustain traffic in the hundreds, thousands or tens of thousand transactions per second, a feat which is reserved ordinarily to applications carefully written by hand at great cost. As such, Metaspex's technology resolves the software conundrum around programmers scarcity, software development costs, quality issues and ever-growing complexity, with a single answer to all these concerns: programming automation. The programmers' workforce can then concentrate on advanced features around User Interface, Analytics, Decision-making software, Data Science in general, Optimization, and Artificial Intelligence.
