Coupled with stateless application servers to execute business logic and a database-like system to provide persistent storage, they form a core component of popular data center service archictectures. Why are developers using RInK systems as part of their design? We’ve seen similar high marshalling overheads in big data systems too.)

When a system ‘scales’ it is able to deliver higher levels of performance proportional to the system resources available to it. In particular, this means as we add CPU cores and increase the system load, we see higher performance. In this example, we will compare MySQL 5.7.33 and MySQL 8.0.25 and MySQL 5.7.33.

That was the provocative thesis of a much-talked-about article from 2003 in the Harvard Business Review by the US publicist Nicolas Carr. The end effect is that the complexity of the system increases, which is not efficient. How companies can use ideas from mass production to create business with data. This pattern should be broken.

Obviously, we don't want to pay to maintain multiple e-Commerce sites or pay licensing fees for multiple ERP systems. We need to combine systems, and do so quickly. There are plenty of cookie-cutter frameworks for combining businesses, even their technology systems and operations. True, but not very helpful.

They create all these systems and processes – and then end up with a very small percentage of people who are supposed to solve complex problems, while the other 98% of people just execute. This leaves the mass of executors wasting effort on misfit solutions, or it leaves them idle, waiting for orders. They implode on themselves.
