Continuous Integration/Continuous Delivery (CI/CD) is crucial for modern software development, offering teams the ability to deliver high-quality code rapidly. Companies often face the decision of building a homegrown CI/CD system or using a commercial solution like CircleCI. Homegrown solutions can cater to specific needs and allow on-premise hosting, but they often become outdated, require extensive maintenance, and incur technical debt. These systems may lack scalability and modern features, leading to inefficiencies and increased costs over time. In contrast, CircleCI provides a reliable, scalable, and flexible platform with seamless integrations and performance monitoring, enabling teams to focus on delivering value rather than maintaining complex infrastructure. Real-world cases like Netguru and nCino demonstrate significant improvements in testing and delivery times after transitioning to CircleCI, highlighting the platform's ability to enhance productivity and support evolving business needs.
