Marco wants to build a set of services for financial transactions for his company. The services need to be capable of scaling quickly to very large numbers of transactions, and need to be able to operate without major dependencies on other components of the architecture. What architecture should he select to best meet these needs?

A microservices design will allow for each component or service to be separate and lightweight, allowing them to be developed independently and thus easier to fix without complex dependencies. Containerization would allow for easy deployment of applications to different service environments, but the focus for containerization is on portability, not on the design requirements listed. Virtualization requires even more resources because operating systems are virtualized, but it suffers from the same lack of a direct means of addressing the needs explained in the question. SCADA stands for supervisory control and data acquisition and is used to manage complex industrial or controls’ environments, not service environments like the question describes.
