Deployment strategies and tips for stable service deployment

Most failures occur during deployment.

Deployment is more than simply the process of applying code to the server. It's a critical step that directly impacts the quality and stability of the service, as well as the user experience. Since even a small deployment error can lead to a major service outage, rapid and safe deployment is essential in modern software development. Especially in environments where technology is rapidly changing and multiple teams collaborate, a more strategic deployment approach is required.

In this lecture, "Deployment Strategies and Tips for Stable Service Deployment," we'll introduce deployment strategies applicable to various situations, drawing on our experience automating deployments using Jenkins. Various deployment methods, such as rolling deployment, blue-green deployment, and canary deployment, each have unique characteristics and benefits and may be optimal for specific situations. We'll cover when and why each deployment strategy is necessary, as well as how to apply them in practice. This will help you minimize risks during deployment and achieve stable service operation.

We also explain how to build a deployment notification system using Slack. Using Slack, you can monitor deployment status in real time and share it transparently with team members, fostering an efficient collaboration environment. We'll also explore what information should be included in notification messages and how to use this to increase the reliability of the deployment process.

Finally, we explain why it's important to understand the difference between development and production environments, and further discuss how to segment your environments to build a stable deployment process. We'll discuss how to thoroughly test in the development environment and safely deploy to the production environment, and we'll also introduce strategies for increasing service stability by segmenting your environment further as needed.

This course provides essential content for those seeking to learn practical deployment strategies and tips beyond deployment automation. It will be helpful to all developers and engineers who aim to reduce deployment failures and ensure stable service operation.
