Version control is a system that manages changes to a set of files or codebase over time, allowing multiple users to collaborate efficiently. It enables tracking of revisions, facilitates branching and merging, and provides a historical record of changes, which is crucial for debugging and maintaining project integrity.
Deployment strategies in software development determine how new versions of an application are released to users, balancing the need for new features with system stability and user experience. These strategies must consider factors like rollback mechanisms, downtime, and user feedback to ensure a smooth transition and quick recovery from potential issues.
A rolling update is a deployment strategy that incrementally updates a service or application to newer versions without downtime, ensuring continuous availability during the update process. It systematically replaces old instances with new ones, verifying their performance and health at each step to maintain stability and minimize service disruption.
Kubernetes Deployment is a resource object in Kubernetes that provides declarative updates to applications, managing the desired state and ensuring running instances match specified configurations. It handles rolling updates, scaling, and rollback capabilities to facilitate reliable and efficient application management across distributed clusters.
