Day-0, Day-1, and Day-2 Operations: What Are the Differences?

Mastering Day-0, Day-1, and Day-2 operations is essential for DevOps teams to efficiently manage the lifecycle of an application from planning and deployment to maintenance and optimization. Day-0 operations focus on planning, including architecture design, tool selection, infrastructure planning, and ensuring security compliance, which sets the foundation for smooth future phases. Day-1 operations involve deploying the application, provisioning infrastructure, deploying code, and configuring security settings to ensure a smooth transition to a live environment. Day-2 operations encompass the ongoing maintenance, monitoring, and optimization necessary to keep applications secure, performant, and scalable. Qovery is highlighted as a platform that simplifies these operations by offering integrated solutions for defining infrastructure as code, automating CI/CD pipelines, and maintaining performance and cost-efficiency through automated scaling and monitoring. The case study of Synota demonstrates how Qovery facilitated zero downtime and cost savings, streamlining deployments and enabling the team to focus on product development.
