SDLC is the process of developing software, starting from an idea and ending with delivery. This process consists of six phases. Each phase takes input from the results of the previous phase. Although the waterfall methods is still widely used today, it's gradually being superseded by more adaptive, flexible methods that produce better software, faster, with less pain. These methods are collectively known as “Agile development.” DEVASCv1 5 Requirements and Analysis Phase . The requirements and analysis phase involves the product owner and qualified team members exploring the stakeholders' current situation, needs and constraints, present infrastructure, and so on, and determining the problem to be solved by the software. -
Designing Software Architecture to Support Continuous Delivery and Devops: a Systematic Literature Review
Designing Software Architecture to Support Continuous Delivery and DevOps: A Systematic Literature Review Robin Bolscher and Maya Daneva University of Twente, Drienerlolaan 5, Enschede, The Netherlands [email protected], [email protected] Keywords: Software Architecture, Continuous Delivery, Continuous Integration, DevOps, Deployability, Systematic Literature Review, Micro-services. Abstract: This paper presents a systematic literature review of software architecture approaches that support the implementation of Continuous Delivery (CD) and DevOps. Its goal is to provide an understanding of the state- of-the-art on the topic, which is informative for both researchers and practitioners. We found 17 characteristics of a software architecture that are beneficial for CD and DevOps adoption and identified ten potential software architecture obstacles in adopting CD and DevOps in the case of an existing software system. Moreover, our review indicated that micro-services are a dominant architectural style in this context. Our literature review has some implications: for researchers, it provides a map of the recent research efforts on software architecture in the CD and DevOps domain. For practitioners, it describes a set of software architecture principles that possibly can guide the process of creating or adapting software systems to fit in the CD and DevOps context. 1 INTRODUCTION designing new software architectures tailored for CD and DevOps practices. The practice of releasing software early and often has For clarity, before elaborating on the subject of been increasingly more adopted by software this SLR, we present the definitions of the concepts organizations (Fox et al., 2014) in order to stay that we will address: Software architecture of a competitive in the software market. -

As organizations start to move into an agile development methodology, they start to uncover other processes that can be accelerated, such as delivery by DevOps and testing by Continuous Testing. The acceleration that is set in motion via agile makes it necessary to accelerate the release schedule. In order to ensure a successful release, an organization must adopt continuous testing to make sure the conveyer belt does not break down. The modernization maturity model has these three distinct phases: AGILE Agile software development is a different way of thinking about approaching the challenge of development time. -

Devops Engineer
DevOps Engineer The IHMC Robotics group is looking to fill a DevOps position. The ideal candidate is somebody who is excited about bringing our lab up to speed on how to best use modern solutions for making our software development and release process super repeatable, reliable, and painless. This is a full-time position. We are huge proponents of strong software engineering practices, leveraging the philosophies of test-driven development, continuous delivery/integration, agile programming, repeatable deployments, and many others that make managing diverse teams and complex software easier. Specifically, the DevOps engineer we’re looking for is awesome at: • Automation. Of everything. An obsession with making every aspect of the development and deployment pipeline painless, testable, repeatable, and reliable is a must-have. • Provisioning and configuration management using tools like Puppet, Chef, Ansible, Salt, etc. The tool of choice is open to discussion, but being comfortable with a provisioning oriented workflow is a must. • Automated Continuous Integration and Continuous Delivery. As a Java shop, we use Gradle as our build system. We are just now beginning to migrate to a full continuous delivery workflow; our builds are becoming more automated with regards to artifact generation, artifact hosting, and integration with tools like Docker. The ideal candidate would be willing to grow a system like this in to something with high reliability so it can be a cornerstone of our open source software workflow. Being test-obsessed is desired, both for making sure our CI stack is doing its job and making sure that your infrastructure automation is just as well tested. -
Development Using Software Quality Control Techniques of a Modern Application for the Shop Floor
Development using Software Quality Control Techniques of a Modern Application for the Shop Floor Report submitted to the Universidade Federal de Santa Catarina as a requirement to approval on the subject: DAS 5511: Projeto de Fim de Curso Rafael Scheffer Berlin, November 2018 Development using Software Quality Control Techniques of a Modern Application for the Shop Floor Rafael Scheffer This paper was judged in the context of the subject: DAS 5511: Projeto de Fim de Curso and approved in its final form by the Course Engenharia de Controle e Automação Prof. Rômulo Silva de Oliveira Examiner Committee: Ricardo Grützmacher Mentor at Rolls-Royce Prof. Rômulo Silva de Oliveira Mentor at UFSC Hector Bessa Silveira Responsible for the Course Leonardo Martins Rodrigues, Committee member Matheus Felipe Souza Valin, Committee member Ígor Assis Rocha Yamamoto, Committee member Abstract Traditional companies, such as Rolls-Royce, are heavily investing in the digitalization of their manual and analog processes. In the department of Assembly and Test, a good example of this type of process is the monitoring of jet engines production in the shop floor, which is done by in-person verification of the module builds, Excel spreadsheets and paper-based systems. These methods are intrinsically slow, inefficient and error prone. As a solution, the development of Shopino, a modern web application for monitoring and data visualization for the shop floor, was proposed. In order to lower costs and save time, the application was developed on top of an existing platform, called Engino. However, since Engino was not finished, it had to be improved and tested. -
