An Empirical Study of Scalability Frameworks in Open Source Microservices-based Systems

On the Nature of Issues in Five Open Source Microservices Systems: An Empirical Study

“…Architectural patterns and tactics for MSA: Architectural patterns and tactics represent generic and reuse-driven knowledge that enables developers and architects to rely on best practices during design and development of MSA-based systems [21]. Several studies, such as [19,22], focused on mining software repositories (e.g., analyzing version control, change logs, and design documents)…”

“…The postmortem analysis of repositories such as GitHub or logs of source code supports the empirical discovery of patterns to address various reuse-driven development [19,21] and evolution issues [1] of MSAs. Specifically, the studies [19,21] investigated artifacts of MSA-based projects deployed on GitHub, such as developers' discussion and source code files, to discover 17 architectural patterns that address reusability [19] and 5 architectural tactics that resolve scalability issues of open-source MSAbased systems. In contrast to the design and development phase, the study in [1] investigated the modernization processes of legacy software to discover and document 15 patterns for architecture-centric refactoring and migration of MSA-based systems.…”

“…In contrast to the design and development phase, the study in [1] investigated the modernization processes of legacy software to discover and document 15 patterns for architecture-centric refactoring and migration of MSA-based systems. To complement repository mining approaches [19,21], the study in [2] focuses on analyzing developers' discussion -investigating human-centric view -regarding MSA development on SO to analyze the topics (e.g., processes, tools, issues, solutions, etc.) that developers find most exciting or challenging.…”

“…To conclude, we categorize the most relevant existing research as (a) repository mining approaches such as [6,19,21] and (b) surveybased studies including [3,26,34] to investigate MSA-based systems and their underlying issues. Specifically, the repository mining approaches exploit GitHub data (e.g., source code, design documents, docker files, and configuration scripts) to pinpoint a number of issues related to reusability and architectural quality [19], service scalability [21], and evolvability [6]. In comparison, our proposed study analyzes the real issues and their discussion by MSA developers on GitHub, to investigate what are the issues and why such issues are caused throughout the life-cycle of microservices systems.…”
