Assignment 2

Fundamentals of Software Architecture

Influence of Architecture Attributes and Styles on

DevOps Transformation [1],[2],[3]

Background

The popularity of Development and Operations (DevOps) and Continuous Delivery (CD)

practice as a promising approach to develop and release software at an accelerated pace has

motivated a widespread research and industrial interest.

The transformation towards DevOps is heavily influenced by software architecture decision. We

need to analyze and understand those architectural decisions, to promote and deploy software

architecture attributes and styles that are compatible and supportive to DevOps-CD objectives.

It is important to understand how an application should be re-architected to support DevOps.

A conceptual framework is needed to supplement the architecting process in a CD context

through introducing the quality attributes that are required to design and deploy operationsfriendly

architectures.

[2] Designing Software Architecture to Support Continuous Delivery and DevOps: A Systematic Literature

Review. Robin Bolscher and Maya Daneva. University of Twente, Drienerlolaan 5, Enschede.

Based on, and according to the referenced three papers, please complete

the following tasks, concisely, briefly, and clearly:

1- Read the three papers and provide a 400-500 words paper summary (use your own

authentic review, and avoid copying unless it is a quotation) of the most important issues

presented for each paper separately, such as research approach (methodology), most

important findings, implication of findings, and conclusion. Include one paragraph to

present you own opinion of the significance and quality of each paper (for specific

details of your summaries, see more details below*. (18 pts)

2- Provide six key architectural decisions that are essential to DevOps transformation.

Provide explanation for each decision with its stated concerns, and implications. (20 pts)

3- Provide 10 attributes of software architecture that are the most important for enabling

CD and DevOps. Explain for each how it impacts DevOps outcome.

State the ones that are most researched in literature (20 pts)

4- What software architecture style is most suitable for being considered in a CD and

DevOps context? Explain the motives for using such style to promote CD/DevOps

practice (16 pts)

5- Achieving DevOps-driven architecture requires loosely coupled architectures and

prioritizing deployability, testability, supportability, and modifiability over other quality

attributes. A conceptual framework [3] shows how to re-architect for CD.

Task response with Max 300 words.

What are the main parts that this framework is consist of? (5 pts)

What are the fundamental motivations behind this framework development? (7 pts)

Explain (in details) how this conceptual framework can support re-architecting a system

for CD support. (14 pts)

*Recommended Research Summary Structure and Organization

Headline – the first contact between the research summary and a reader is its title. Generally, headlines formed as

questions work perfectly. At the beginning of the writing process, it may be tricky to come up with a headline. Instead,

create it once you’re done with writing, you’ll have plenty of ideas to use

What is this research about? (3-5 sentences) – introduce the research and its primary objective. Consider this part as

an announcement of some event, you need to provide necessary details to ensure audience understands everything

and wants to learn more. Define important terms from the research paper, especially if they aren’t common

knowledge.

Methods (5-10 sentences) – research summary (and original file) aren’t just about findings that are of huge interest

for the topic, methods also matter. Once you’ve explained the purpose of the research, move on to describe the

methodology and elaborate how researchers collected data and include examples of questions that were asked.

Findings (5-10 sentences) – this section is unavoidable. After researchers or scientists implemented their methods,

what did they discover? Describe key findings from the study itself. Don’t waste your time including every finding from

a specific study, just the key points.

How can you use the research? (3-7 sentences) – describe how findings from the research can be used by

practitioners in different fields. Identify who would be interested in the results of the study

Conclusion (3-4 sentences) – this section tells a reader what he/she needs to know about the research. Basically, this

is a short overview of the summary that compiles key points of the study and its finding into a single section.
