My Opinion on Semaphore

Value For Money

Overall Opinion: Continuous integration (CI) is a development paradigm that enables developers to push their changes to a code repository several times per day. The code is then automatically tested through an automated build process, with the goal of identifying bugs or problems early and allowing more time to fix them prior to going into production. Continuous deployment (CD) is an extension of CI, which takes the tested and approved changes and deploys them to the production environment. Semaphore is a software suite that provides software testing automation and aids with deployment. It has over 100 languages and tools pre-installed and integrates easily with Docker for virtualized end-to-end testing. It provides graphical reporting on build results, to help you visualize where things are failing. Because of the dedicated hardware resources available to the Semaphore servers, it can process builds more quickly than competing products. The application's optimized code identifies and caches project dependencies to improve performance as well. Semaphore offers parallel test execution, and there are special "boosters" available to further increase the speed of your builds. The boosters use a sample build as a template. You specify the optimal number of jobs that can process in parallel, and the booster does the rest. You don't need to make any modifications to your code to experience this improved performance: the booster handles it all in the background. And Semaphore handles deployment as well. Set up multiple environments for developer testing, user acceptance testing and production, and configure them for manual or continuous deployment. Semaphore's integration with popular cloud-based environments seamlessly handles deployment automatically, or you may choose to simplify your custom deployment using scripts. Finally, Semaphore provides you with reporting on your testing and deployment processes that keep you in-the-know with regard to your development life-cycle. You can see a history of commits, the results of testing and your deployment history.

Pros: Semaphore delivers fast build times through the implementation of a powerful build platform and parallel processing. Integration with GitHub and Bitbucket simplify implementation for existing projects. Semaphore enables continuous deployment, meaning that all your approved changes are automatically deployed to your testing or production environment.

Cons: If your company's development culture is not already implementing CI/CD, it can be a significant paradigm shift. There can be cultural, workflow and testing process changes required for a successful implementation. In addition, developers must learn new push and pull routines and integrate them into their development process. Especially for an organization new to CI/CD, there can be an increased risk of changes being pushed to production that hasn't been fully tested or that aren't really ready yet. Developers may be so focused on development that they don't see the build failures and fix them right away, leading to downstream issues and derailing the CI/CD process.
