Rolling Deployment Vs. Blue-Green: Which Strategy Fits Your Pipeline?
Blog post from Flagsmith
The text explores three deployment strategies—rolling, blue-green, and canary deployments—emphasizing their differences, advantages, and trade-offs. Rolling deployments update instances in sequential batches without requiring a duplicate environment, making them cost-effective but potentially complex due to version coexistence. Blue-green deployments maintain two identical environments, allowing for near-instantaneous rollback and zero downtime but at the cost of doubling infrastructure expenses. Canary deployments offer a middle ground by gradually introducing new versions to a small user segment, allowing for real-user validation and minimizing risk. The choice between these strategies depends on factors like infrastructure budget, risk tolerance, and the need for rapid recovery from failed releases, with each approach offering unique benefits and challenges tailored to different organizational needs.
