Changes in general and environment is much more dynamic than it was only couple of years ago. A good process is like a good recipe. A Vision, that shows the long-term technical shape of the project. One of the main tasks for solution architect is to make such system that is highly independent from: vendor, database, programming language, framework, etc. In Software Architecture, a good process can help us remove all the extra effort required for repetitive tasks such as: Sometimes we don’t notice how much time takes, as a whole group, thinking about this kind of questions. The similar is for solution architecture discipline. Preparing the Software Architecture Roadmap, Part 6. Problem. A well-oiled website and its applications represent the face of a company, and in an ideal scenario, they serve as … Ensure software meets all requirements of quality, security, modifiability, extensibility etc. The hardware architecture (the software architect in turn provides requirements to the system architect, who configures the hardware architecture). In the past, I’ve been required to fill in a document of about ten pages each time we wanted to include a new library as a dependency in our Java project. That’s what you’ll learn with this guide. Experienced software architects share their defining moments. Always tend to fight with legacy. To achieve independence described in the paragraph above you need to invest very much time and money. The software architecture consists of an assortment of design artifacts typical of other engineering disciplines, such as diagrams, drawings, and static and dynamic models. It allows us to set up actual phases that can show the design intent at the various levels of completion. Other books focus on software and system architecture and product-line development. I would recommend starting with the book Software Architecture … In information technology, architecture plays a major role in the aspects of business modernization, IT transformation, software development, as well as other major initiatives within the enterprise. Solution architecture is the initial step taken when an organization aims to create a set of enterprise solutions, applications and processes that integrate with each other in order to address specific needs and requirements and that often lead to software architecture and technical architecture work. These and all books in the series address critical problems in software engineering for which practical solutions are available. Everybody knows where to find the outcome from previous actions (e.g. system crash. Another potential symptom of not counting with a good process is having a Meeting-Only Software Architect, that only participates in the software creation process with design meetings, which outcome does not include an action plan and which contents are normally forgotten in a week. When picking one try to understand its health from the perspective of frequency of commits, list of bugs, community size, help materials, the speed of release of fixes, etc. What i like to do in that case is to ask them how they solved some common issues that this architecture brings with it. Information architectureis the structure of information from the user … Part 1. Creating, and especially helping others create, new ideas that may provide competitive differentiation to the project. Even though the Software Architects may have a perfect picture of the entire architecture landscape in their minds, for the developers there is a feeling of chaos and the odds are that you deviate from the decisions and conventions very often. Legacy system stayed legacy system. The word process may trigger a negative feeling. Even so, best practices unique to solutions architecture have emerged, as new attention is paid to the field. “We have a feature that we do not want noticed.” Inevitably in buildings there are a few necessary … Quality Attributes. It is in very unmanageable state. The cause of problem is in fact that there is no technology/language that can cover any platform/challenge. To me it happened couple of times that some companies wanted to impress me by stating that their architecture is based on microservices. There is no single reason behind those problems, it’s like a cocktail with several possible ingredients: Having a good process in place will help you deal with these situations and come up with productive outcomes. It defines a structured solutionto meet all the technical and operational requirements, while optimizing the common quality attributes like performance and security.
