One of the most critical challenges in software development is providing users with updates and new features without causing any hiccups or downtime. Many development teams used to plan deployments for times throughout the night or during the day when users were least likely to be accessing the applications. Easy-to-find deployment windows are no longer relevant since customers want cloud-based, round-the-clock environments accessible in all time zones. Fortunately, blue-green and canary deployment configurations are popular strategies that avoid risks and downtime almost wholly.
