Microservices Architecture & Data: Managing the Use of Data with Microservices
The Open Group
Mishandling data can jeopardize the benefits of MSA. This document explores the central question of which data should be contained within Microservices and what should be kept outside, and looks at the complexities of data and MSA interaction and the preservation of MSA's primary advantages (of resilience, scalability, and development agility) in an evolving industry with new Data Architecture styles, such as data mesh, to enable organizations to achieve high levels of efficiency and…

A Self-Adapting IoT Network Configuration Supported by Distributed Graph Transformations
MDPI Applied Sciences Journal
The research described in this article proposes the creation of a framework that enables the self-optimization of IoT device networks. The network of distributed IoT devices is visualized as a graph, and graph transformations are used to specify and optimize the network in response to events such as degraded performance, failures, or configuration changes. The article provides both formal definitions and a practical example of the proposed solution.

TOGAF® Series Guide: Microservices Architecture (MSA)
The Open Group
This document provides guidance on how the architect can use the TOGAF® Standard to develop, manage, and govern Microservices Architecture (MSA) or any architecture where MSA is part of the scope. This should promote the shared understanding of the MSA creation process according to the principles of distributed architecture, and significantly strengthen the alignment between the cultures of business and information technology. The further adoption of MSA as an architectural style in a cloud…
This document provides guidance on how the architect can use the TOGAF® Standard to develop, manage, and govern Microservices Architecture (MSA) or any architecture where MSA is part of the scope. This should promote the shared understanding of the MSA creation process according to the principles of distributed architecture, and significantly strengthen the alignment between the cultures of business and information technology. The further adoption of MSA as an architectural style in a cloud environment would result in the use of the method, metamodel, references, and other TOGAF facilities.

Benefits of DevOps Methodology for Microservices Solutions
The Open Group
This White Paper describes the business and technology-related benefits realized by the combination of Microservices and DevOps. It builds on The Open Group White Paper: Microservices Architecture (MSA) and explores the scenarios where the use of DevOps in conjunction with MSA will significantly improve DevOps objectives. The focus is on the architectural aspects of DevOps, not on particular frameworks and products.

REVIEW OF THE DATA MODELING STANDARDS AND DATA MODEL TRANSFORMATION TECHNIQUES
Applied Computer Science
Manual data transformations that result in high error rates are a big problem in complex integration and data warehouse projects, resulting in poor quality of data and delays in deployment to production. Automation of data transformations can be easily verified by humans; the ability to learn from past decisions allows the creation of metadata that can be leveraged in future mappings. Significant improvement of the quality of data transformations can be achieved, when at least one of the models…
Manual data transformations that result in high error rates are a big problem in complex integration and data warehouse projects, resulting in poor quality of data and delays in deployment to production. Automation of data transformations can be easily verified by humans; the ability to learn from past decisions allows the creation of metadata that can be leveraged in future mappings. Significant improvement of the quality of data transformations can be achieved, when at least one of the models used in transformation is already analyzed and understood. Over recent decades, particular industries have defined data models that are widely adopted in commercial and open source solutions. Those models (often industry standards, accepted by ISO or other organizations) can be leveraged to increase reuse in integration projects resulting in a) lower project costs and b) faster delivery to production. The goal of this article is to provide a comprehensive review of the practical applications of standardization of data formats. Using use cases from the Financial Services Industry as examples, the author tries to identify the motivations and common elements of particular data formats, and how they can be leveraged in order to automate process of data transformations between the models.
