Including microservices in architecture

DevOps is about gaining higher productivity with faster releases of code. DevOps teams can focus on specific tasks and code that is designed to only perform that task. They develop the code independently from other services to increase focus, the speed of delivery, and customer experience. Security principles are applied to these services and continuously validated by the means of automated scanning. DevOps is by default distributed architecture, in contrast with monolithic architectures where systems are designed and built as a whole. In DevOps, the architecture will be driven by microservices: an application is defined as a collection of independent services that will communicate with each other over specified protocols. The following figure shows the principle of microservices:

In terms of security, we can assume that microservice architectures are more secure than monolith...
