    Obscuring Complexity

    One of the most important things that software architects do is manage the complexity of their systems in order to mitigate release disruption while maintaining sufficient feature velocity. When we cannot reduce complexity, we try to hide or shift it. Software architects tend to manage that complexity with the time-honored strategies covered in this article.

    Evaluating Hyperledger Composer

    Hyperledger Composer is a new open source project which makes it easy for developers to write chaincode for Hyperledger Fabric and the decentralized applications (DApps) that can call them. This article summarizes a technical evaluation of the performance characteristics of using Composer in a test application.

  • Architectural Refactoring: A Task-Centric View on Software Evolution

    In this article, author discusses Architectural Refactoring (AR) techniques to improve the quality attributes without changing the system's scope and functionality. He also provides a TaskCentric Template and Architectural Refactoring Catalog.

  • IT Architecture Design Framework: ADMIT

    ADMIT details the decisions points that should be considered by any IT Architecture effort. While its format is similar to other Enterprise Architecture frameworks, its focus on characteristics and forces which affect the end result allow it to be used in conjunction with other formalized EA deign and evaluation methodologies.

  • Pattern-Based Architecture Reviews

    In this IEEE article, authors Neil Harrison and Paris Avgeriou discuss a pattern-based architecture review (PBAR) process to help with system-wide quality attributes. They also discuss how PBAR approach helps with agile practices like frequent releases, changes for user needs, and lightweight documentation. They illustrate the benefits of PBAR process with a real-world project.

  • Rick Kazman on Evaluating Software Architectures

    Evaluating software architectures is a critical part of the software architecture lifecycle processes. The book "Evaluating Software Architectures: Methods and Case Studies" covers the software architecture evaluation topic in detail focusing on different architecture evaluation frameworks. InfoQ spoke with Rick Kazman, co-author of the book on the architecture evaluation topic.

  • Trust is good, Control is better - Software Architecture Assessment

    Testing is an important means to obtain information about implementations. Likewise, code reviews help to keep the code quality high. What is very common for code, gets sometimes neglected for software architecture. But how can a project team test the architecture itself? Software architecture assessment represents an effective approach for introspecting and assessing software design.

    Are You a Software Architect?

    The line between development and architecture is tricky. Some say it's fake, that architecture is an extension of the design process undertaken by developers; others say it's a chasm that can only be crossed by lofty developers who believe you must abstract your abstractions and not worry about implementation details. There's a balance in the middle, but how do you move from one to the other?

  • Book Excerpt and Interview: Open Source SOA

    Boris Lublinsky interviews Jeff Davis as part of a review of Davis' new book, Open Source SOA. The book covers the selection and usage of the open source products for SOA implementation. The interview poses questions about SOA as "business problem" or technical distributed system; SOAP vs. REST; WSDL, and "adherence to standards" as an evaluation criteria, among other topics.
