Mitigate risk with rolling deployments

Rolling deployments are an effective method of minimizing risk during software updates. They involve gradually replacing nodes in the production environment with new ones, ensuring that only one additional node is active at a time. This approach reduces costs and vulnerability by limiting the impact of potential bugs or issues to a small percentage of users. Additionally, rolling deployments allow for quick rollbacks if necessary. While there are some complexities involved, such as compatibility and notification challenges, these can be mitigated with proper planning and tools like Sleuth. Overall, rolling deployments offer significant benefits in terms of risk reduction and cost savings compared to other deployment methods.
