Comparative Study on Agile software development methodologies

Today-s business environment is very much dynamic, and organisations are constantly changing their software requirements to adjust with new environment. They also demand for fast delivery of software products as well as for accepting changing requirements. In this aspect, traditional plan-driven developments fail to meet up these requirements. Though traditional software development methodologies, such as life cycle-based structured and object oriented approaches, continue to dominate the systems development few decades and much research has done in traditional methodologies, Agile software development brings its own set of novel challenges that must be addressed to satisfy the customer through early and continuous delivery of the valuable software. It is a set of software development methods based on iterative and incremental development process, where requirements and development evolve through collaboration between self-organizing, cross-functional teams that allows rapid delivery of high quality software to meet customer needs and also accommodate changes in the requirements. In this paper, we significantly identify and describe the major factors, that Agile development approach improves software development process to meet the rapid changing business environments. We also provide a brief comparison of agile development methodologies with traditional systems development methodologies, and discuss current state of adopting agile methodologies. We speculate that from the need to satisfy the customer through early and continuous delivery of the valuable software, Agile software development is emerged as an alternative to traditional plan-based software development methods. The purpose of this paper, is to provide an in-depth understanding, the major benefits of agile development approach to software development industry, as well as provide a comparison study report of ASDM over TSDM.Comment: 25 pages, 25 images, 86 references used, with authors biographie

Enhancing design learning using groupware

Project work is increasingly used to help engineering students integrate, apply and expand on knowledge gained from theoretical classes in their curriculum and expose students to 'real world' tasks [1]. To help facilitate this process, the department of Design, Manufacture and Engineering Management at the University of Strathclyde has developed a web±based groupware product called LauLima to help students store, share, structure and apply information when they are working in design teams. This paper describes a distributed design project class in which LauLima has been deployed in accordance with a Design Knowledge Framework that describes how design knowledge is generated and acquired in industry, suggesting modes of design teaching and learning. Alterations to the presentation, delivery and format of the class are discussed, and primarily relate to embedding a more rigorous form of project-based learning. The key educational changes introduced to the project were: the linking of information concepts to support the design process; a multidisciplinary team approach to coaching; and a distinction between formal and informal resource collections. The result was a marked improvement in student learning and ideation

Continuous integration and application deployment with the Kubernetes technology

Poslední dobou by téměř každý chtěl své aplikace nasadit do Kubernetes. Jenže pro plné využití Kubernetes je třeba přijmout s otevřenou náručí postupy průběžné integrace (CI) a nasazení (CD). Je třeba CI/CD pipeline. Ale k dispozici je až zdrcující množství open-source nástrojů, kde každý pokrývá různé části celého procesu. Následující text vysvětlí základy technologií, kterých bude pro pipeline třeba. A následně shrne některé z populárních open-source nástrojů využívaných pro CI/CD. Z open-source nástrojů navrhneme pipeline. Závěrečné porovnání možných řešení (včetně proprietárních) poskytne čtenáři konkrétní tipy a rady ohledně vytváření vlastní pipeline.It seems nearly everyone would like to deploy to Kubernetes nowadays. To efficiently leverage the power of Kubernetes one must first fully embrace continuous integration (CI) and deployment (CD) practices. A CI/CD pipeline is needed. But there is an overwhelming amount of open-source tools that cover various parts of the whole process.The following text explains the basics of the underlying technologies needed for a pipeline deploying to Kubernetes. And subsequently summarizes some of the popular open-source tools used for CI/CD. Then it designs a working pipeline from the researched tools. Finally, it summarizes some of the possible pipelines (including proprietary) and provides the reader with specific bits of advice on how to implement a pipeline
