Integration
TLDR: Integration in software development refers to the process of combining individual components or subsystems into a cohesive application or system. It ensures that modules, developed independently, work together seamlessly, supporting functionality and data flow across the system. Integration is a cornerstone of DevOps and agile methodologies, enabling frequent and efficient collaboration between teams and technologies.

In modern development workflows, integration often involves continuous integration (CI), where code changes are automatically merged, tested, and built into a shared repository. Tools like Jenkins, Travis CI, and GitLab CI/CD facilitate this process by automating tasks such as dependency management and testing, reducing the risk of integration conflicts. Integration also includes combining diverse technologies, such as APIs, third-party services, and heterogeneous systems, ensuring they operate in harmony.

Integration extends to testing, where integration testing validates interactions between modules to ensure they perform as expected. It also plays a crucial role in microservices and cloud-native architectures, where components must communicate effectively over networks. By adopting robust integration practices, organizations can improve system reliability, accelerate delivery timelines, and minimize errors during development and deployment.
