Hexagonal Architecture, firstly introduced by Alistair Cockburn back in early 2000s, (who is also one of the main protogonists of Manifesto of Agile Software Development) is pretty popular architectural style applied to layered architectured software systems, which lack of flexibility, entaglement. This architectural pattern is widely inspired by Eric Evan’s…

Application of different Service Mesh Tactics — Performance concerns are driving forces for software architects to come up with new techniques for more efficient software performance. The performance is also hot topic for teams applying microservices. The extreme popularity of microservices has led to evaluation of service mesh pattern/architecture (whatever you want to call this…). In software…

Designing well-established Interfaces — There is no software system in isolation. Software systems communicate with each other to request or response some data. This is also called interoperability. Interoperability is about the degree to which two or more systems can usefully exchange meaningful information via interfaces in particular context. Software systems can exchange this…

In Java world, Spring Framework/Boot is a must-have skill set. XML-Based Configuration was for a long time main mean. But overloaded xmls with unreadable structure has become quickly headache for developers. Spring has started to switch from XML-based configuration to Annotation-based Configuration. Nowadays, greenfield projects are structured almost always in…

Monolithic applications are still overwhelmingly widespread in IT industry, since the most applications have legacy past and had been built with standards of their era. Microservices is trending software architecture pattern that become industry standard for greenfield projects. …

So far we have discussed different software architecture topics in more low-level aspects, focusing on designing specific parts of software system separately such as backend, frontend, middleware etc. With this article we take the discussion to one step further and discuss designing a software system end-to-end. In designing whole system…

Canary, A/B Testing, Ramped, Blue/Green, Recreate… — In Cloud-Computing there are plenty of ways to construct the new release deployment process. The correct strategy must be chosen accurately to have a stable application while new release rollout. In tools like Kuberenetes or Openshift you can preconfigure the exact deployment strategy easily. …

Master Plan for becoming a Software Architect — Software Architects are senior level actors in software development team. It takes time and experience to become the one. The skills and knowledge that you need to accumulate are cross-functional. Besides having challenges first of all in technical sphere, this position also demands from architects to have a well-established social…

Technical Debt is a hot topic in all software development projects that over time gets more sophisticated as source code grows gradually. There are plenty of tools analyzing technical debt that basically concentrates on code quality. …
