CI/CD Optimization Assessment Realizing the Full Potential of Your Continuous Integration / Continuous Delivery & Deployment Pipeline
InterVision Professional Services CI/CD Optimization Assessment Realizing the Full Potential of Your Continuous Integration / Continuous Delivery & Deployment Pipeline ACCELERATE: Jumpstart your CI/CD efforts with expert guidance, planning, and design tailored to your specific environment. VALIDATE: Perform a ‘checkup’ on your existing automation strategies and tools to identify opportunities for additional efficiency. IMPROVE: Break through existing automation and quality challenges with third party expertise and detailed recommendations. Increasing Automation to Gain Competitive Advantage Automating the software production pipeline can deliver significant benefits to the business. Continuous Integration / Continuous Delivery (CI/CD) represents a practical benchmark for the level of automation desired by companies that create software, which is growing every day. An organization leveraging CI/CD can produce software faster, with higher quality, and release it to its users more quickly, which in turn delivers competitive advantages over companies still struggling with automation. Continuous Deployment represents an even higher state of automation but most organizations are quite content in getting to CI/CD and tackling Continuous Deployment as a follow on. Leveraging CI/CD, development groups can get new features out to customers at a faster rate, which pleases existing customers and attracts new ones. CI/CD also allows more of the code to be tested, and more rigorously at that, through testing automation. The resulting quality can become a symbol of the company and improve its brand and its market share. Modern development practices like CI/CD can also drive employee retention. Developers are happy working in modern development environments where they can focus on coding and are free from fixing recurring problems that the CI/CD practices have eliminated. -

All Rights Reserved. 2 Overview In traditional software development, developers check out the code and work on it separately until they finish the task. Then all these changes get merged into base code at the choice of the lead developer. The merge process tends to happen infrequently—sometimes weeks but sometimes months. The process of sorting merge conflicts can get very complicated since multiple people are working on same codebase and the number of changes can be significant. Building toward a ‘monolithic‘ merge and release is fraught with risk. There are too many assumptions, plenty of opportunity for miscommunication and added complexity if something needs to get “undone.” With the tooling available today, build and merges should happen at least daily. In doing so, the amount of risk is reduced exponentially. So, integrating the source code frequently is highly recommended and a best practice. Each time the code is integrated, it should be tested. In traditional development teams, this involves the following steps: Integrating the source code when a developer commits the changes to source code Build/release engineer builds the software after the integration QA tests the build Feedback is provided to the respective developer in case of defects The software is then marked as usable The goal of CI/CD (continuous integration/continuous delivery) is for these tasks to be automated. -
Efficient Automated Build and Deployment Framework with Parallel Process
ISSN (Online) : 2278-1021 ISSN (Print) : 2319-5940 International Journal of Advanced Research in Computer and Communication Engineering Vol. 3, Issue 6, June 2014 Efficient Automated Build and Deployment Framework with Parallel Process Prachee Kamboj1, Lincy Mathews2 Information Science and engineering Department, M. S. Ramaiah Institute of Technology, Bangalore, India 1, 2 Abstract: Continuous integration has been in theory for a long time but successful practicing is still a dream. To resolve the integration problems and increase the customer satisfaction, it is important to follow the practice of continuous integration in software development. Doing manual build and deployment regularly results in lot of time consumption and thus becomes an inefficient process. This paper proposes architecture for build and deployment by following best practices. It aims to fully automate the build process by using some available tools for source management, binary management and compilation. Build architecture gives a method to integrate all tools in build server. Successful completion of build is followed by deployment. This paper also proposes a deployment architecture which is common for all development environments. Deployment architecture states three steps, required to do the deployment and also proposes optional features to enhance the deployment process. Keywords: Automation, Build, Continuous Integration, Deployment, Parallel I. INTRODUCTION Software development is done in different environments. Generally industry follows four environments which are Development, Quality Assurance, Stage, and Production [1] . Before delivering the software to the customer it is essential to test the software and ensure the quality of Figure 1: Build and Deployment automation for different development software. The environments should not intersect as the Environments activities between each group in software development This paper proposes a new build and deployment should not interfere with one another. -

Improving C++ Software Quality with Static Code Analysis
Aalto University School of Science Degree Programme in Computer Science and Engineering Elias Penttilä Improving C++ Software Quality with Static Code Analysis Master’s Thesis Espoo, May 16, 2014 Supervisor: Professor Lauri Malmi Advisor: Kaj Björklund, M.Sc. (Tech.) Aalto University School of Science ABSTRACT OF Degree Programme in Computer Science and Engineering MASTER’S THESIS Author: Elias Penttilä Title: Improving C++ Software Quality with Static Code Analysis Date: May 16, 2014 Pages: 96 Major: Software Systems Code: T-106 Supervisor: Professor Lauri Malmi Advisor: Kaj Björklund, M.Sc. (Tech.) Static code analysis is the analysis of program code without executing it. Static analysis tools are therefore a useful part of automated software analysis. Typical uses for these tools are to detect software defects and otherwise suspect code. Several algorithms and formal methods are available specializing in code analysis. Token pattern matching is used by simpler tools, while more in-depth tools prefer formal methods such as abstract interpretation and model checking. The choice of algorithms thus depends on the preferred analysis precision and soundness. We introduced the practical problems facing static analysis, especially in the con- text of C++ software. For static analysis to work in a satisfiable way, the tool must understand the semantics of the code being analyzed. Many tools, particularly open-source ones, have deficiencies in their capabilities of code understanding due to being unable to correctly parse complex C++. Furthermore, we examined the difficulty of handling large numbers of warnings issued by these tools in mature software projects. As a summary, we presented a list of five open-source and six commercial static analysis tools that are able to analyze C++ source code. -
Implementing a Container-Based Build Environment: a Case Study
Implementing a container-based build environment: a case study Paavo Pärssinen School of Science Thesis submitted for examination for the degree of Master of Science in Technology. Espoo 20.12.2019 Supervisor Prof. Casper Lassenius Advisor M.Sc. Risto-Matti Vuonnala Aalto University, P.O. BOX 11000, 00076 AALTO www.aalto.fi Abstract of the master’s thesis Author Paavo Pärssinen Title Implementing a container-based build environment: a case study Degree programme Computer, Communication and Information Sciences Major Computer Science Code of major SCI3042 Supervisor Prof. Casper Lassenius Advisor M.Sc. Risto-Matti Vuonnala Date 20.12.2019 Number of pages 63+1 Language English Abstract Containers have become a widely adopted way to package and distribute software. Their portability, ease of use and small computational overhead are some of the main features driving their popularity, as well as their adoption into modern cloud architectures. Some developers have also come to realize the advantages of using containers as a way to package dependencies and tools, easing the set-up and migration of development environments across computers. In this case study, we studied the process of moving an entire software department to a workflow, where the default way of building and testing the project softwareis in a container. The department consists of nearly 200 developers developing Layer 1 software for 5G radio base stations. Two interview rounds were conducted, of which the first analyzed the initial state of the workflow in the department. Thesecond interview round was conducted after taking a containerized build environment into use. In addition, a literature review was conducted on the technologies related to the solution, as well as on previous studies related to the subject. -
Master Thesis Submitted in Fulfilment of the Requirements for the Academic Degree M.Sc
PERFORMANCE EVALUATION AND OPTIMIZATION OF CONTINUOUS INTEGRATION BASED AUTOMATED TOOLCHAIN FOR SAFETY RELATED EMBEDDED APPLICATIONS SOFTWARE Master Thesis Submitted in Fulfilment of the Requirements for the Academic Degree M.Sc. Dept. of Computer Science Chair of Computer Engineering Submitted by: Zain Ullah Student ID: 395153 Date: 25.10.2016 Supervising tutor: Prof. Dr. W. Hardt Donny Masril [Baumer Hübner GmbH] Abstract Continues Integration has been a vital part of software development process in order to make the development process fast and reliable. There are number of actors which play an important role with support of third party tools that helps the development process to be effective and productive in nature. The CI- toolchain is capable of doing much more than the compilation of the software project which covers the daily life tasks of the developers like testing, documentation etc. The important part of automated toolchain is the conversion of source code artifacts into executables with the help of the build system. The selection of proper build system is a matter of subjective in nature and it depends upon the number of factors that should be analyzed before proceeding forward towards the selection mechanism. This thesis focuses on software rebuilding and proves practically with experiments that could help developers and managers to decide between two important software build systems SCons and CMake. It has been experimentally proved that what are the conditions and situations where SCons performs better and what are the moments where it is wise to select CMake as a build tool. At first, individual build tools are evaluated in terms of scalability, conveniency, consistency, correctness, performance (in terms of speed and targets) and later, the build systems are experimented by automating the workflow by increasing the source code artifacts to evaluate the performance when there is limited user interaction. -
