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…

Software Architects, as mentioned in my early blog posts, are often experienced Software Engineers with programming background. Over time when Engineers convert to Tech Leads or Software Architects, they program less and manage more. Generally, Software Architects are dealing with more high-level design, IT documentation, requirements engineering, resource management etc…

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. Many teams tend to migrate old Monolithic applications to Microservices, which is…

Working with Versioning Tools for Source Code Management has been must-to-know in last decade for Software Engineers. Tools like GitHub, Bitbucket etc. are pretty popular in Software Engineering world that all have their own specifications with some common functionalities instead. Being familiar with Git Commands gives the user more freedom…

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. Without further due, let us have…

Designing specific Architecture for a software system, especially for greenfield projects, requires solid planning and preparation. There are plenty of methodologies that are used by experienced Software Architects for designing greenfield projects, one of which is Attribute-Driven Design. Attribute-driven design is a methodology to create software architectures that takes into…
