I will try not to repeat the benefits of microservices or other supporting elements that you need to have, to migrate into such an architecture. Increasingly, there are more articles, blogs and other content available about the pitfalls and the kind of safety nets that you should have before or during the transition to granular services. There are many resources which highlight pros of having more granular services explained part of microservices narratives. It is about separating the monolithic applications into multiple stand alone service applications or developing them separately from the beginning with the help of bounded contexts, a DDD concept. The architectural style I would like to talk about is very similar to microservices. Bounded Contexts Designed as Service Applications

Sometimes these technical rules are perceived as hard barriers implementing the DDD, but at the end, people tend to forget that the important part is to organize code artifacts in alignment with business problems and using the same common, ubiquitous language as (1). It describes independent steps/areas of problems as bounded contexts, emphasizes a common language to talk about these problems, and adds many technical concepts, like entities, value objects and aggregate root rules to support the implementation. When building applications, DDD talks about problems as domains and subdomains.

As it is now getting older and hype level decreasing, many of us forget that the DDD approach really helps in understanding the problem at hand and design software towards the common understanding of the solution. Domain Driven Design advocates modeling based on the reality of business as relevant to our use cases. We look at individual pieces and recognize our collective experiences with design patterns or techniques and try to apply the best of the choices.Īn interesting software design technique to understand and solve complexity is Domain Driven Design (DDD). We realize that we cannot formulate a complete process that fits all. We started to break them into different applications with goals to easily manage individual applications, develop and deploy faster with lesser dependencies, and lastly bring more freedom of technological choices. The same applies to the software that we’ve modeled after problems.
As in real life, we try to focus on not detailing the whole process, but to try and understand the overall journey by looking at our latest performances. While for years waterfall-like formulated recipes have been applied to the software development process, in the end, mostly heuristic and experience based estimation techniques (planning poker, t-shirt sizing) and agile processes have prevailed. This is not different in the software development world. This is related to the size of the tasks to accomplish.The underlying real criteria is about timing or schedule, our energy to execute, our cognitive capacity and its relation to familiarity of tasks and maybe even the physical locations where those tasks can be executed (consulate vs. When we handle one of the steps, we don't keep all the details of the process in our minds, we just do the task at hand.

We learn that we need a visa to travel, we slowly grasp the documentation needs, what forms are to be filled and how to fill these. We don't use a formula to understand what is required to travel to a country that requires a visa. By decomposing the problem, we turn it into more understandable and manageable pieces.Īs is described in many product/project management cycles, for real life problems, this is usually driven by instinct. When we face complex problems, we usually try to understand the individual pieces of complexity. I won’t be talking particularly about service endpoint design, but I would like to discuss the ideation phase for creating multiple service applications. Particularly about larger systems which could potentially be separated into multiple deployables in the form of service endpoints. This piece is about making choices for software design.
