Software projects are becoming complex, larger, more integrated, and are implemented by the use of several varieties of technologies. Quality attributes usually assessed and analyzed at the architecture level, not at the code level. However, some experts start talking about it, for example, I highly recommend you to attend Global Software Architecture Summit in Barcelona ( October, 1-2), where Alexander von Zitzewitz will talk about “Software Metrics for Architects”.

Microservices, serverless, AI, ML, and Kubernetes are among the most notable topics in our analysis of proposals from the O’Reilly Software Architecture Conference. The speaker proposals we receive for the O’Reilly Software Architecture Conference are valuable because they come from speakers who are often the leading names in their fields. They also understand that business and architecture can no longer be compartmentalized, and that revenue is at stake.

This notion has been reinforced through four decades of work in computer architecture and software after it was first driven home to me by a luminary in computer architecture at Intel Corporation, the late George Cox.

Leveraging Hexagonal Architecture We needed to support the ability to swap data sources without impacting business logic , so we knew we needed to keep them decoupled. We decided to build our app based on principles behind Hexagonal Architecture and Uncle Bob’s Clean Architecture. The idea of Hexagonal Architecture is to put inputs and outputs at the edges of our design. The dependency graph in Hexagonal Architecture goes inward.

Is there any way it’s possible to predict the future so that our architecture can easily absorb the changes we need to make of it? One thing I want you to notice is that good architecture is about more than just defining good boundaries. Getting the interactions right between the components of your architecture is equally important for loose coupling and evolvability. In DDD a bounded context is an independent, loosely-coupled architectural component.

This is the question I get asked the most, so I’ve put together this article describing a workshop recipe you can use. In Domain-Driven Design, a large system is decomposed into bounded contexts , which become natural boundaries in code as microservices and as teams in the organisation. There is no shortcut to identifying good boundaries.

Let's talk about the elephant in the room; Serverless doesn't really mean that there are no Software or Hardware servers. It just means that from Software Development perspective, servers are abstracted and outsourced to another entity, so you don't need to worry about it. Serverless is currently a hot topic in many modern architectural patterns. This has a huge impact on application architecture, however having said that, it's not necessarily a bad idea.

When your software system communicates with external systems or devices, there is good reason to isolate all communication with the external system into a single place and perform the relevant translation there.
