![CI and CD -- what they are and why they're not the same [Q&A] - Vimarsana News](https://betanews.com/wp-content/uploads/2023/11/CI-CD-DevOps.jpg?w=640)
You'll often hear CI (continuous integration) and CD (continuous deployment) mentioned in the same breath, often as CI/CD, and indeed both are part of improving the quality, speed and efficiency of software development.
In the ever-evolving landscape of software development, the mantra "Shift Left, Write Right" has emerged as a guiding principle. This approach emphasizes early and continuous testing, collaboration, and a focus on quality throughout the development lifecycle. Let's delve into the significance of this mantra and explore how it shapes the realms of software development, with a particular focus on the role of software testing companies.
Business intelligence (BI) was once heralded as a technology that would democratize data, enabling everyone to become more productive and make better decisions. Today, though, analysts in the BI space like to share the same (and possibly apocryphal) statistic: The global business intelligence adoption rate is only 26 percent.
A typical software development process is sequential (1970s-1990s): define requirements, analyse, design, code, test and deploy. In this process, testing happens towards the end. Problems uncovered by testing at such a late stage can cause costly redesign and delays. The idea of Shift Left is to involve testing teams earlier in the process and to think about testing at all stages of the process.
Continuous Integration (CI) is a cornerstone of modern software development. By automatically checking for regressions and linter errors on each Pull Request (PRs), CI frees engineers to focus on more nuanced, qualitative aspects of code review.
